fix(guardrails): add /v1/messages support for Straiker plugin (#34548)
* fix(guardrails): add /v1/messages support for Straiker plugin

- Pass prepared response data to Anthropic Messages streaming post-call hooks (litellm/llms/anthropic/chat/guardrail_translation/handler.py)
- Normalize Straiker request, tool, finish-reason, and mode fields across Chat Completions, Messages, and Responses APIs

* fix(guardrails): gate cross-surface message resolution and cover streaming request data

Resolve request messages only for surfaces that have a mapped translation
handler. The unguarded fallback tried every registered handler in turn, which
raised AttributeError out of the guardrail's error handling on list-shaped
`input` bodies, and synthesized a chat message that was never sent for bodies
it happened to parse.

Prepare request data on the mid-stream Anthropic branch as well, matching the
terminal branch and the OpenAI handler, so guardrails that scan before
end-of-stream still receive identity metadata.

Read usage from Anthropic dict responses so non-streaming /v1/messages reports
token counts instead of null.

Add regression coverage for the streaming request data on both the terminal and
mid-stream branches; reverting either now fails.

9777e9524a fix(guardrails): stop reporting a no-op guardrail as applied on passthrough
On passthrough requests the shared guardrail plumbing still dispatches
headroom's pre_call apply_guardrail, but the passthrough translation hands it
only `texts` and no `structured_messages`, so it early-returns a no-op. The
@log_guardrail_information decorator then synthesized an "allow"/"success"
StandardLoggingGuardrailInformation entry, and the unified hook added the
guardrail to applied_guardrails, so spend logs reported the compression
guardrail as succeeded even though nothing ran.

Add a records_own_guardrail_information flag for guardrails that log their own
execution (headroom). The decorator skips the synthetic success entry for them,
and the unified hook lists such a guardrail in applied_guardrails only when it
actually recorded a run. A guardrail that owns its logging must record every
outcome it runs, so headroom now records a guardrail_failed_to_respond entry on
the fail_open path (compression attempted, service unreachable, request
forwarded uncompressed) instead of leaving it unlogged; fail_closed is still
recorded by the decorator's error path, and a genuine no-op stays not_run.

770f41b5fa fix(guardrails): keep guardrail information in spend logs when the caller sends its own metadata
The guardrail-information writer picked its metadata bucket with a hand-rolled
precedence that preferred a caller-supplied `metadata` field, while every reader
resolves the bucket through `get_metadata_variable_name_from_kwargs`, which
prefers `litellm_metadata`. The two rules agree only when the caller sends no
`metadata` of its own. Routes in `LITELLM_METADATA_ROUTES` seed `litellm_metadata`,
so on /v1/messages and /v1/responses a caller that sends `metadata` sent the entry
to a dict nothing reads; the spend log then reported `guardrail_status: not_run`
with no `guardrail_information` even though the guardrail ran and the
`x-litellm-applied-guardrails` header was present.

Give the resolver one owner. `get_or_create_metadata_bucket` moves from the proxy
layer into core_helpers next to the resolver it calls, so `litellm/integrations`
can reach it without a proxy dependency, and the byte-identical duplicate of
`get_metadata_variable_name_from_kwargs` in callback_utils is deleted. The writer
now shares that owner with `add_guardrail_to_applied_guardrails_header`, so the
response header and the spend log can no longer disagree.

Two readers had to move with it or the fix would be a no-op on the affected
routes. `_sync_guardrail_info_to_logging_obj`, which bridges request_data into the
spend-log payload for passthrough routes, picked the first truthy bucket, so a
non-empty caller `metadata` short-circuited it. The otel failure-path span reader
`_emit_guardrail_spans_from_request_data` read a hard-coded `metadata` key, which
also dropped the span whenever the entry lived in `litellm_metadata`.

Model Armor already resolved the bucket for its file-scan results but wrote its
text-scan and post-call results, and read them back in `_process_response`,
through a hard-coded `metadata` key; on a seeded route that split the record so a
file scan's evidence never reached the logger. All four Model Armor sites now use
the shared resolver. The unified guardrail hook seeds `litellm_metadata` on every
route, so the OpenAI moderation entry lands there too; spend-log output is
unchanged because `merge_litellm_metadata` reads both buckets.

feat(guardrails): add run_in_parallel opt-in for concurrent pre_call and post_call guardrails (#33770)
* feat(guardrails): add run_in_parallel opt-in for concurrent pre_call guardrails

Pre-call guardrails run sequentially because each may mutate the request
payload and later guardrails depend on earlier mutations. Deployments with
several slow block-only pre_call guardrails (external moderation, Bedrock,
LLM-judge) therefore pay the sum of their latencies. during_call guardrails
run concurrently but alongside the LLM call, so a violating payload has
already been sent, which is unacceptable when the request must never reach
the model.

This adds a per-guardrail run_in_parallel flag (default off). Guardrails that
opt in are pulled out of the sequential loop and run concurrently via
asyncio.gather after every sequential (payload-mutating) guardrail has run, so
they observe the mutated payload and still form a hard barrier before the LLM
call; the first to raise blocks the request. Their returned data is discarded
since they are declared block-only.

The flag is wired from LitellmParams onto the guardrail instance at the same
generic choke point in initialize_guardrail that already sets
skip_system_message_in_guardrail, so no per-provider initializer needs to
change.

* feat(guardrails): extend run_in_parallel opt-in to post_call guardrails

post_call_success_hook ran guardrails sequentially for the same reason
pre_call did: response-modifying guardrails thread the response forward. But
block-only output scanners (which read the response and reject on violation
without changing it) serialize for no benefit and add latency.

This reuses the existing run_in_parallel flag for the post_call hook. Opted-in
post_call guardrails are pulled out of the sequential loop and run concurrently
via asyncio.gather after the sequential (response-modifying) guardrails and
before the non-guardrail CustomLogger callbacks, so they inspect the final
response and still block it from reaching the client if any raises. Their
returned response is discarded since they are block-only.

The apply_guardrail path sets data["guardrail_to_apply"] immediately before
awaiting, and unified_guardrail pops it before its first suspension point, so
concurrent guardrails never race on that key under asyncio's cooperative
scheduling.

* fix(guardrails): await all parallel guardrails and prioritize blocks over reroutes

Addresses review feedback on the run_in_parallel opt-in.

asyncio.gather propagated the first exception without cancelling or awaiting
the siblings, so a block at t=0 left the other guardrails running as
unobserved background tasks (wasted external calls plus event-loop warnings),
and a fast SensitiveDataRouteException/ModifyResponseException could return a
reroute or passthrough before a slower block finished, letting crafted input
bypass the block. Both the pre_call and post_call parallel batches now gather
with return_exceptions=True so every guardrail runs to completion, then raise
any blocking exception ahead of a flow-changing one.

The registry choke point wrote bool(None)==False onto every instance when the
config omitted run_in_parallel, silently disabling a constructor-set default;
it now only writes when the config provides an explicit value.

* fix(guardrails): record lifecycle logs for every concurrently-run guardrail

The log_guardrail_information decorator skipped its auto-record when it saw
that the count of standard_logging_guardrail_information entries in the shared
request_data had grown during the wrapped call, taking that as proof the
wrapped function had recorded its own richer entry. That heuristic breaks the
moment guardrails run concurrently (parallel pre_call/post_call, during_call):
a sibling guardrail's append inflates the shared count, so a guardrail that did
not self-record wrongly concludes it already did and drops its own entry. The
result is that enabling run_in_parallel silently loses per-guardrail lifecycle
logs, so the Admin UI Request Lifecycle timeline and downstream loggers
(Datadog, Langfuse, OTEL, spend logs) show only one of the concurrent
guardrails.

Replace the shared-count heuristic with a ContextVar flag set when a guardrail
records its own entry. asyncio copies the context into each gathered task, so
the flag is isolated per concurrent guardrail while still catching the
self-record-then-skip-auto-record case within a single invocation.

* test(guardrails): declare run_in_parallel on post_call guardrail mocks

The post_call partition reads run_in_parallel on every CustomGuardrail
callback. A MagicMock(spec=CustomGuardrail) has no run_in_parallel (it is
set in __init__, not on the class) so the attribute access raised, and even
a class-level default would return a truthy child mock that wrongly routes
the double into the parallel batch. Declare the flag False on the shared
mock factories so these pre-existing hook tests exercise the sequential
path they assert on.

* fix(guardrails): harden run_in_parallel reads and address review feedback

Read run_in_parallel via getattr(..., False) in the pre_call and post_call
partitions so a third-party CustomGuardrail subclass that overrides __init__
without chaining super().__init__() no longer raises AttributeError on a path
that previously worked. Drop the redundant in-function GuardrailEventHooks
import in _run_parallel_post_call_guardrails (already imported module-level).
Remove the flaky wall-clock upper-bound assertions from the two concurrency
tests; the all-start-before-any-end overlap assertion is the timing-independent
signal that actually proves concurrency.

fix(guardrails/model_armor): handle None metadata in post_call _process_response (#34390) (#34405)
* fix(guardrails/model_armor): handle None metadata in post_call _process_response

On batch routes data["metadata"] is normalized to None (present key, None
value), so request_data.get("metadata", {}) returned None and _process_response
raised 'NoneType' object has no attribute 'get', 500ing every /v1/batches create
with a post_call Model Armor guardrail (regression from v1.93.0 activating the
post_call hook). Coalesce a falsy metadata to {}

* fix(guardrails): run only_scan_new_messages in the unified apply_guardrail path

The initial wiring lived in BedrockGuardrail.async_pre_call_hook, but the proxy
routes Bedrock through the unified apply_guardrail interface, so the flag had no
effect live. Move incremental selection into apply_guardrail: filter the flat
texts list against per-session scanned hashes, skip the Bedrock call when nothing
is new, and mark hashes only after a successful (non-blocked) scan. Full-context
fallback is preserved when there is no session id, the cache is unavailable, or a
masking guardrail is configured.

fix(model_armor): sanitize error details by default (#33908)
* fix(model_armor): sanitize error details by default

Generated with AI

Co-Authored-By: Claude Code

* fix(model_armor): sanitize handler-raised HTTP errors and redact scanned content in guardrail logging

The async HTTP handler raises MaskedHTTPStatusError on any non-2xx via
raise_for_status, so the non-200 branch in make_model_armor_request never ran
against a live API and the raw upstream body reached callers and logs. Catch
the raised error and build the sanitized detail from the response status

Replace the empty-dict guardrail logging payload with field-level redaction of
the keys that echo scanned content (text, sanitizedText, findings) so guardrail
traces keep filter states and block reasons while scanned content stays out

Restore the upstream status code in the sanitized error detail, read guardrail
metadata from the same key the hooks write, and keep guardrail_status within
its typed literal values

* fix(model_armor): bound redactor recursion depth and allowlist it in the recursion detector

_redact_scanned_content walks provider JSON bounded by _REDACT_MAX_DEPTH=20 and
fails closed by returning the redaction sentinel at the cap

* fix(model_armor): honor fail_on_error for upstream API failures

API failures now raise a dedicated ModelArmorAPIError so hooks can tell them
apart from content-block HTTPExceptions; fail_on_error=False lets the request
proceed on a Model Armor outage again while fail-closed configs get the same
sanitized 400 as before

Also addresses review notes: sanitize_error_detail constructor annotation
matches the nullable config field, redaction is owned by the metadata write
sites so _process_response no longer re-applies it, and the request and
response debug log branches move into helpers

* test(model_armor): cover fail_on_error routing on during-call, post-call, streaming, and file-scan paths

* chore: remove accidentally committed pytest cache files

* fix(model_armor): keep sanitize_error_detail coerced across in-memory config reloads

update_in_memory_litellm_params assigns raw LitellmParams fields, so a hot
reloaded config carrying an explicit null would silently disable sanitization;
re-apply the only-explicit-False-opts-out coercion after the update

* fix(model_armor): redact matched malicious URIs and reuse the shared recursion depth constant

maliciousUriMatchedItems echoes the caller-supplied URL including path and
query, so it joins the scanned-content key set; the redactor depth cap now
comes from DEFAULT_MAX_RECURSE_DEPTH in litellm constants instead of a local
literal

* fix(model_armor): keep API failures out of the intervention trace status

Fail-closed upstream failures re-raise ModelArmorAPIError instead of
converting to HTTPException(400), so the shared guardrail logging keeps
recording them as guardrail_failed_to_respond while content blocks stay
guardrail_intervened. Callers see the same 500 shape as before this PR,
with the sanitized message

* chore(model_armor): drop explanatory comment per repository comment policy

* adding deepkeep as custom guardrail

* adding deepkeep as a custom guardrail

  reach the DeepKeep API
- user_api_key_hash: only fall back to user_api_key_token when no

Adds tests for all four fixes.

* fix: add missing __init__.py and allowlist entries for upstream merge

- tests/test_litellm/proxy/client/__init__.py: fixes pytest collection
  collision with tests/test_litellm/models/test_models.py (same basename)
- tests/test_litellm/models/__init__.py: same fix
- backend/routes/allowlist.py: add /config_overrides/ and /v1/unified_access_group

* fix(ui/tests): resolve frontend-lint failures in new test files

- useLogDetails.test.ts: add Wrapper.displayName, replace 'null as any'
  with null, type resolveCall promise resolver properly
- usePaginatedDailyActivity.test.ts: remove unused waitFor import,
  add Wrapper.displayName, change Record<string,any> to Record<string,unknown>
- UsageViewSelect.adminFiltering.test.tsx: replace all props:any with
  explicit SelectProps/BadgeProps/SelectOption types, replace (X as any).displayName
  with direct X.displayName assignment

no-explicit-any count: 2034 (budget: 2040). Prettier check: clean.

* fix(ui): sync proxy/_experimental/out/ exactly to upstream

245 stale JS chunk files from earlier merges were left in the out/
directory but had been deleted in upstream. The Docker image in CI is
built by copying this directory verbatim, so the stale artifacts caused
the SERVER_ROOT_PATH redirect E2E to fail.

Synced by: git checkout upstream/litellm_internal_staging -- out/ (adds
new files) + git rm on every file present in HEAD but absent from
upstream.

* Update litellm/proxy/guardrails/guardrail_hooks/deepkeep/deepkeep.py

Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com>

* fix(makefile): fall back to upstream/litellm_internal_staging for strict-budget gate

origin/litellm_internal_staging exists on BerriAI's CI but not on forks
that use a different remote name (e.g. Azure DevOps as origin).  Fall
back to upstream/litellm_internal_staging when the origin ref is absent.

* linter reformat

* fix(deepkeep): apply guardrail tool/tool_call redactions from API response

When DeepKeep returns GUARDRAIL_INTERVENED with redacted tools or
tool_calls, the previous code ignored those redactions and forwarded
the original (potentially sensitive) values to the model — a guardrail
bypass for content embedded in tool schemas or function arguments.

Fix: prefer response_json["tools"] / response_json["tool_calls"] when
present, falling back to the originals only when the guardrail did not
return replacements — consistent with the existing pattern for texts and
images.

Refactor _build_return_inputs() into a private static helper to keep
apply_guardrail() under the PLR0915 statement limit (50).

Adds test_apply_guardrail_applies_tool_redactions_from_response to
assert that redacted tool payloads from the API response are used.

* Update litellm/proxy/guardrails/guardrail_hooks/deepkeep/deepkeep.py

* fix(lint): move base-ref fallback into ruff_strict_gate.py; revert Makefile

The previous Makefile fix had a shell bug: 'git rev-parse --verify'
writes the resolved SHA to stdout, so the $$(...) substitution captured
both the SHA and the echo output, handing '--base <sha>\norigin/...' as
two tokens to the Python script, causing exit code 1 in CI.

Fix: revert Makefile to its original single-line invocation and add
_resolve_base() to ruff_strict_gate.py. The function checks whether the
requested ref resolves; if not, it tries the 'upstream/' equivalent
before falling back to the original ref (letting git emit a clear error).

Behaviour in BerriAI CI: origin/litellm_internal_staging resolves → used
as before, no change.
Behaviour on forks with a different 'origin': falls back to
upstream/litellm_internal_staging transparently.

* fix(lint): fix UP006/UP045/F401 in changed files; add depth guard to check_any_discipline

- Replace Dict/List/Optional/Tuple typing imports with built-in equivalents
  (UP006, UP045) across files touched in this PR diff, then clean up
  the now-unused typing imports (F401).
- Add _MAX_CONTAINS_ANY_DEPTH guard to check_any_discipline.contains_any()
  to prevent RecursionError on deeply-nested mypy types.

* fix(lint): resolve all three CI lint job failures

1. lint (ruff_strict_gate) — UP006/UP045/F401 violations introduced on
   changed lines. Fixed Dict/List/Optional/Tuple → built-in equivalents
   across every file in the PR diff; cleaned up now-unused typing imports.

2. any-discipline — RecursionError in check_any_discipline.contains_any()
   on deeply-nested mypy types. Upstream fixed this by converting to an
   iterative stack-based algorithm (merged). Also added deepkeep.py to
   any-discipline-budget.json via 'make lint-any-budget-update' so the
   new file's Any count is baselined instead of failing against the
   zero-baseline default.

3. basedpyright reportMissingParameterType — **kwargs in DeepKeepGuardrail
   __init__ lacked a type annotation. Added **kwargs: Any.

* Update litellm/deepkeep_tilt_config.yaml

Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com>

* fix(lint): black reformat after merge

* fix(deepkeep): honour empty-list replacements in _build_return_inputs

When DeepKeep returns GUARDRAIL_INTERVENED with an intentional empty
replacement (e.g. texts:[], tool_calls:[]) the previous truthiness check
treated [] as absent and forwarded the original content downstream —
a guardrail bypass for any case where the firewall wants to fully clear
a field.

Fix: replace all response_json.get(field) truthiness checks with
'is not None' comparisons so that an empty list is respected as a
deliberate replacement. Applies to texts, images, tools, tool_calls,
and the original-input fallback guards.

Adds test_apply_guardrail_honours_empty_list_replacements.

* fix(test): replace live httpbin.org call with mocked transport in test_pass_through_with_httpbin_redirect

Root cause of OOM: the test made a real HTTP request to https://httpbin.org
inside a pytest-xdist worker. Under memory pressure the worker's httpx client
and redirect-following logic allocated enough virtual memory to trip the OOM
killer (confirmed by ulimit -v 16GB reproducing the crash with 'node down: Not
properly terminated' on this exact test).

Fix: replace the real network call with a custom httpx.AsyncBaseTransport that
returns a pre-built 302 -> 200 response sequence in-memory. The test now runs
hermetically with no network dependency and no excess memory allocation.

ulimit -v 16GB: 24,284 passed (0 crashes) after this fix.

* fix: merge upstream/litellm_internal_staging (197 commits), resolve conflicts

7 conflicts resolved:
- 6 Python files: upstream added new code with old-style typing (Optional,
  Dict, List) on lines where we had ruff-fixed modern syntax (str | None,
  dict, list). Took upstream's version then re-ran ruff UP006/UP045/F401
  --fix to keep both the new content and ruff compliance.
- test_openapi_compliance.py: upstream replaced 'role' with 'steps' in
  output_fields and updated the spec comment. Took upstream's version.

Also: added _resolve_base() fallback to type_check_gate.py and removed
the hard 'git fetch origin litellm_internal_staging' from the Makefile's
lint-basedpyright target (same pattern as ruff_strict_gate.py fix).

* fix: merge upstream (41 commits), resolve .gitignore conflict, fix BLE001

- .gitignore: upstream removed package.json/out/ ignore entries; took theirs
- deepkeep.py: added '# noqa: BLE001' on catch-all Exception handler
  (BLE001 rule newly enforced in ruff-strict-budget)
- type_check_gate.py: added _resolve_base() fallback for basedpyright gate
- Makefile: removed hard 'git fetch origin' from lint-basedpyright target

* fix: merge upstream (57 commits), resolve conflicts

- Makefile: upstream added lint-fetch-base target; made it tolerant of
  missing origin/litellm_internal_staging (git fetch || true)
- test_websearch_chat_completion.py: took upstream's new assertions and
  skipif marker
- anthropic_cache_control_hook.py: upstream added new code using List/Dict/Tuple
  which were undefined after our earlier UP006 cleanup; replaced with
  built-in list/dict/tuple

* fix(coverage): revert ruff UP006/UP045 changes on upstream files

The previous ruff fixes (Dict→dict, Optional→X|None) on 7 upstream files
added ~500 changed lines of pure type-annotation no-ops to our PR diff.
codecov/patch penalised these uncovered lines, dropping patch coverage
to 51.35% (target 61.83%).

Fix: revert these files to exactly match upstream/litellm_internal_staging.
The ruff_strict_gate still passes because the violations exist equally in
both the base and HEAD (total == base_count → no breach).

* fix: merge upstream (130 commits), resolve Makefile + base_email conflicts

- Makefile: upstream changed lint deps to $(LINT_DEP_INSTALL)/$(LINT_DEP_BASE);
  kept our --base removal (handled by _resolve_base in Python scripts)
- base_email.py: took upstream's dedup cache addition
- deepkeep.py: ruff format after merge

* chore: remove lint/format-only changes and non-feature files

Revert all lint-infra and black/ruff-reformat-only changes back to
upstream/litellm_internal_staging so the PR diff shows only the DeepKeep
guardrail feature:
- Makefile, scripts/ruff_strict_gate.py, scripts/type_check_gate.py
  (lint-gate infra)
- credential_migration.py + enterprise/* + assorted test files
  (black-reformat / xdist test-isolation drift)
- backend/routes/allowlist.py (merge glue)
Remove non-feature local artifacts: build-and-push.sh,
deepkeep_tilt_config.yaml, stray __init__.py collision shims, and
unrelated UI test files.

* fix(lint): add reason to BLE001 noqa to satisfy type-discipline gate (LIT003)

The type-discipline budget ratcheted LIT003's ceiling to 292 as upstream
fixed reasonless suppressions, so our '# noqa: BLE001' (code but no
reason) tipped the total to 293 and failed CI. Add a reason per the
required '# noqa: CODE  # <reason>' shape.

* fix(deepkeep): apply structured_messages redactions returned by the guardrail API

_build_return_inputs dropped any structured_messages the DeepKeep API returned and
always forwarded the original input, so redactions on that field never took effect.
Check the response first, same as texts/images/tools/tool_calls

* chore(ui): drop redundant preserve prop from the guardrail form

preserve defaults to true in rc-field-form (isMergedPreserve falls back to true when
unset), so the explicit prop changed nothing and only widened this PR's blast radius
to every guardrail provider in the shared form

* fix(deepkeep): stop extra_headers list from crashing the guardrail call and name the real firewall id config key

litellm_params.extra_headers is a list of header names to forward, so passing it
straight into dict.update raised ValueError and, under fail_closed, took the request
down with it. Only merge mapping values and warn otherwise

The docstring example and the missing-secret error both said firewall_id, but
initialize_guardrail only reads deepkeep_firewall_id, so anyone following them
had their value silently ignored

* refactor(proxy): drop normalize_callback change; split to its own PR (#33905)

feat: add Straiker guardrail integration (#33781)
* feat: add Straiker guardrail integration

Implements LLM security guardrails via Straiker with prompt and response inspection, multi-mode execution (pre_call, post_call), and configurable blocking or redaction of flagged content across providers, streaming, images, and tool calls.

* fix(guardrails): harden straiker source attribution and error-path consistency

Use the operator-configured source for Straiker application attribution instead of a caller-supplied agent_id metadata value, so a caller cannot spoof which application a detection is attributed to. Make _fail reuse _block so a post_call error raises ModifyResponseException like a deliberate post_call block rather than GuardrailRaisedException, and type the blocking helper as NoReturn so the type checker enforces that execution never falls through the BLOCKED branch. Serialize the webhook payload once and send it as raw content to avoid re-serializing on the size check and on every retry.

* fix(guardrails): read straiker config and metadata from all supported shapes

Handle a dict optional_params in _get_config_value so nested guardrail
settings loaded from YAML or the DB (timeout, unreachable_fallback, and
the rest) are applied instead of silently falling back to defaults;
previously only attribute-style access was supported. Build the webhook
metadata bag from the merged metadata so client tags stored under
litellm_metadata on routes like /v1/messages reach Straiker the same way
identity and application fields already do, and widen the internal-key
skip prefix to user_api so proxy-injected budget values are not
forwarded.

* fix(guardrails): fail safe on straiker interventions without redactions

Block instead of passing content through when Straiker returns
GUARDRAIL_INTERVENED without replacement texts, so a positive
intervention verdict can never silently forward the original flagged
content. Fix the streamed-request detection to read the request body
from proxy_server_request.body, where the proxy stores it, instead of a
top-level body key that is never populated; the previous fallback was
dead, so a streamed response whose stream flag was not lifted to the top
level would have been redacted rather than blocked while buffering
replayed the original chunks.

* revert(guardrails): restore straiker caller agent_id application attribution

Restore the original behavior where a request-scoped agent_id in metadata
sets the Straiker application source, falling back to the configured
source. This is the integration's intended per-application attribution;
litellm already resolves a key-owned agent_id ahead of any caller-supplied
value, so a configured key cannot be spoofed.

* revert(guardrails): restore straiker webhook metadata scoping

Restore the original behavior where the Straiker webhook metadata bag is
built from request-scoped metadata only. Forwarding litellm_metadata was
a scope change to what the integration sends to Straiker; keep the
author's intended scoping.

* fix(guardrails): keep proxy key material out of straiker webhook metadata

Widen the internal-key skip prefix from user_api_key_ to user_api so the
proxy-injected user_api_key hash and user_api_end_user_max_budget are not
copied into the Straiker webhook metadata bag. The narrower prefix missed
the bare user_api_key name, leaking the hashed key to the vendor. Keeps
the request-scoped metadata source unchanged.

chore(ci): merge oss branch (#33784)
* fix(embeddings): accept encoding_format='float' for vertex_ai/gemini embeddings (#33617)

OpenAI SDKs (and litellm's own client since ~1.84) send
encoding_format='float' by default, but the vertex embedding config only
supports ['dimensions'], so get_optional_params_embeddings raised
UnsupportedParamsError at the provider default value. Any
OpenAI-compatible client talking to a litellm proxy with vertex
embedding models got a 400 unless the operator set proxy-wide
drop_params: true.

Float lists are exactly what the vertex API returns, so the param is a
no-op: pop it before validation. Other values (e.g. 'base64') keep the
existing unsupported-param behavior (dropped with drop_params, raise
otherwise).

Fixes #33173

* Fix non-conformant UUIDv7 generation in native Opik integration (#31294)

create_uuid7() encoded the timestamp in units of 16 seconds instead of
milliseconds, so the top 48 bits came out ~4096x the real unix-ms. Opik's
backend validates the embedded UUIDv7 timestamp on ingestion (OPIK-7067);
the bad encoding decoded to ~year 2201 and every trace/span batch was
rejected with HTTP 400.

Rewrite create_uuid7() to be RFC 9562 conformant (top 48 bits = unix-ms),
using the standard library only so no new dependency is added. Add unit
tests covering UUIDv7 validity and millisecond timestamp encoding.

* feat(proxy): expose uvicorn concurrency limit (#33077)

Expose uvicorn's limit_concurrency as a --limit_concurrency CLI flag and
LIMIT_CONCURRENCY environment variable. Uvicorn counts both active tasks and
accepted connections and returns HTTP 503 once the configured limit is reached.

Reject non-positive limits at CLI parse time and only add the setting to the
uvicorn startup arguments. Because idle connections also consume capacity,
deployments should use upstream connection/header timeouts and per-client
connection limits.

* test: reorder test_utils tail to keep the daily merge conflict-free (#33788)

The daily OSS branch and litellm_internal_staging each appended an
independent test block at the very end of tests/test_litellm/test_utils.py,
so merging the two collides on that shared end-of-file position even though
the additions are unrelated (this branch adds the vertex embedding
encoding-format tests; staging adds the per-model prompt-cache-minimum
tests). Moving this branch's new TestVertexEmbeddingEncodingFormat class
above test_gemini_image_models_do_not_support_reasoning, which both branches
share, gives the two additions different anchors, so git applies both
without a conflict and without pulling staging into this branch. Pure
reorder; no test bodies change

feat(guardrails): forward optional metadata on POST /guardrails/apply_guardrail (#33067)
Clients calling the standalone apply_guardrail endpoint had no way to pass
per-request configuration to custom guardrail implementations. This adds an
optional metadata field to ApplyGuardrailRequest and forwards it to
CustomGuardrail.apply_guardrail via request_data, only when the client sends
it. The messages guard is aligned to the same is-not-None semantics so an
explicitly-sent empty list is forwarded instead of silently dropped.

The Admin UI's Guardrail Test Playground gains an optional Metadata JSON
input (validated client-side) wired through applyGuardrail in networking.tsx,
so parameterized guardrails can be exercised from the dashboard.

Tests cover metadata alone, metadata with messages, explicit empty values,
the omitted-field passthrough, and the UI panel's parse/error behavior

feat(guardrails): add Compresr guardrail for query-aware context compression (#33295)
* feat(guardrails): add Compresr guardrail for query-aware context compression

Adds a first-class guardrail that compresses bulky message content (tool
outputs, RAG chunks, search results) through the Compresr API before the
request reaches the LLM, via the apply_guardrail / structured_messages hook
so it covers /chat/completions, /v1/messages, and /v1/responses (the latter
through the texts channel, mirrored only when the replacement is
unambiguous; anything ambiguous is left uncompressed).

Distinct from whole-conversation compressors:
- Query-aware: each message is compressed against the intent that produced
  it (a tool output against its originating tool call's name + arguments,
  resolved via tool_call_id; otherwise the last user message).
- Recoverable: each compressed message carries a hash marker and the request
  gains a compresr_retrieve tool, so the model can pull the original content
  back through the agentic loop when the compressed version is not enough.
  Originals are cached in-process, scoped to the caller's virtual-key hash
  plus the request's litellm_call_id, with a TTL and a per-call byte cap;
  recovery is skipped when no caller scope is available so one caller can
  never read another's originals. The store is per-process, so multi-worker
  deployments need sticky routing (or enable_retrieval=false).

Fail-closed by default (fail_open configurable), SSRF-validated api_base
(alternate IP-literal encodings included), cross-tenant-isolated recovery
store, and upstream errors redacted from client-facing responses. The
outbound client follows redirects and re-resolves DNS per request, so the
api_base host/IP checks are defense-in-depth, not a full SSRF guarantee;
this is documented as a known limitation. Requests where nothing was
actually compressed are returned untouched (same object identity) so
handlers skip the write-back. Auto-discovered via the guardrail_hooks
registry.

* fix(guardrails): cap Compresr recovery store total memory

The recovery store bounded bytes per call and entry count, but had no
aggregate cap: 256 tracked call ids at the 10 MiB per-call default could
retain ~2.5 GiB per worker. A flood of requests with distinct
x-litellm-call-id values and large compressible tool outputs could
exhaust a shared proxy worker.

Add a global byte budget (_MAX_TOTAL_STORE_BYTES, 256 MiB) across all
entries. A running total is maintained on every insert/eviction so the
cap is enforced without re-encoding the whole store on the request path;
oldest entries are evicted once the budget is exceeded, always keeping
the most-recent entry so recovery still works for the request populating
the store. +2 regression tests.

* fix(guardrails): gate and bound Compresr recovery loop

Two hardening fixes to the compresr_retrieve agentic loop:

1. Only run the loop when a retrieve call resolves to recovery state this
   guardrail actually created for the request. Previously the gate checked
   only that the caller-supplied tool list contained a compresr_retrieve
   function and that the model emitted a call, so a caller could define
   their own same-named tool and force an extra provider round-trip with
   nothing to recover. The plan now returns run_agentic_loop=False when no
   requested hash resolves.

2. Bound the follow-up against retrieval amplification: each distinct hash
   is expanded at most once (repeats get a short marker) and at most
   _MAX_RETRIEVALS_PER_LOOP calls are honored, so prompting the model to
   call compresr_retrieve many times with the same marker cannot balloon
   the follow-up. _retrieve_original now returns None on miss.

+3 regression tests; two existing security tests updated to assert the
stronger veto behavior (forged/cross-tenant hashes now stop the loop
entirely instead of returning a not-found follow-up).

* fix(guardrails): warn when Compresr recovery is skipped without auth scope

When enable_retrieval is on (the default) but the proxy has no per-key
auth, the request has no caller scope, so recovery is silently disabled:
content is compressed but the compresr_retrieve tool is never injected and
the originals are dropped, with no runtime indication. Emit a one-shot
call-time warning so operators can see recovery is being suppressed and
configure virtual-key auth. +1 regression test.

* style(guardrails): tighten Compresr guardrail comments

Condense the verbose multi-line inline comments and the api_base docstring
to concise form. No behavior change.

* fix(guardrails): keep injected tool on Responses API + bound recovery markers by byte cap

Two fixes for reviewer-flagged defects in the Compresr guardrail:

- Responses API: _merge_tools_after_guardrail iterated only over the
  request's original tools, dropping any tool a guardrail appended (the
  compresr_retrieve recovery tool) whenever the request already had tools.
  Keep the appended tools so recovery works on /v1/responses.

- Recovery markers: markers + originals were built for every compressed
  target before the per-call byte cap trimmed the store, so an evicted
  original left a marker the model could never retrieve. Attach recovery
  only while the store (existing entries under the same key + this call's
  originals) stays within the cap, so a shipped marker is always retrievable
  -- including on a later turn that reuses the store key.

Adds regression tests for both paths.

* refactor(guardrails): extract _existing_originals to keep apply_guardrail under the complexity gate

The byte-cap fix added a branch to apply_guardrail, tipping it past the
C901 complexity ceiling. Move the store lookup into a small helper; no
behavior change.

* fix(guardrails): harden Compresr SSRF blocklist, re-arm no-scope warning, tolerate odd tool shapes

* fix(guardrails): rerun input guardrails on Compresr retrieval follow-up

* chore: remove unrelated deepkeep files committed by mistake

feat(bedrock guardrails): add resource-less InvokeGuardrailChecks (detect-only) mode (#33299)
* feat(bedrock guardrails): add resource-less InvokeGuardrailChecks (detect-only) mode

Adopted from #30830 by OS-joaocastilho; the original PR was merged into
litellm_oss_staging_230626, which never landed, so this re-lands it on
litellm_internal_staging

Beyond the original diff, this fold includes the review fixups that were
made on the staging branch (warn on unrecognized check keys, keep empty
known checks as enable-with-defaults, fail fast when the checks block has
no usable keys, tz-aware datetimes, stricter typing) and adapts the block
path to the ModifyResponseException contract from LIT-4186, which replaced
GuardrailInterventionNormalStringError after the original PR was written

* fix(bedrock guardrails): only evaluate configured checks in violation collection

An unsolicited score in the InvokeGuardrailChecks response (e.g. a future
API revision returning checks the user never requested) previously fell
through to the default 0.5 threshold and could block a request the user
only asked to scan with other checks. Violation collection now skips any
check absent from the configured checks block

* fix(bedrock guardrails): fail closed on truncated PII results and tighten checks-path typing

Truncated sensitiveInformation results now count as a violation when the
PII check is configured: Bedrock omitted detections that were never
scored, so sub-threshold visible entries no longer let the request pass.
Also blocks on score == threshold per the documented contract (regression
test added), rejects checks combined with guardrailVersion, turns a
malformed 200 body into a logged guardrail_failed_to_respond 500 instead
of a raw ValidationError, types the checks parameter and violations
(BedrockChecksConfigModel, BedrockChecksViolation) instead of dict/object,
types _sign_and_post against AWSPreparedRequest, hoists stdlib imports,
and builds checks messages without intermediate mutation

* fix(bedrock guardrails): tag all InvokeGuardrailChecks INPUT content as user

Bedrock excludes system content from prompt-attack evaluation (per the
AWS guardrails docs), so mapping a caller-supplied system/developer
message onto the system role let a caller hide a prompt injection from
the promptAttack check by self-labeling its role. At the proxy every
INPUT message is caller-controlled, so all of it is now tagged as
untrusted user input, which also matches AWS guidance to tag untrusted
content as user input. OUTPUT stays assistant. Removes the now-unused
role map; the input-message test asserts the new tagging as a regression

* fix(bedrock guardrails): pass prepared request headers to httpx without dict coercion

httpx accepts botocore's HTTPHeaders mapping directly, and wrapping it in
dict() broke the existing test_bedrock_guardrail_make_api_request_passes_api_key
which supplies a bare Mock as the prepared request (dict(Mock) calls
Mock.keys())

* test: move ComplianceChecker mode tests to the compliance PR

* fix(guardrails): strip content from tool-call passthrough so streamed text can't bypass the transform

* fix(guardrails): four correctness fixes for incremental_diff streaming path

Four bug fixes on top of the OSS PR's incremental_diff streaming text
transformation, all inside the incremental_diff code paths only. No
existing block_only, non-streaming, or pre_call behavior is touched.

Fix #1 — Mixed content+tool_call finish_reason ordering
  _tool_call_passthrough_chunk now takes an optional finish_reason_per_choice
  map. For a choice carrying both delta.content and delta.tool_calls,
  finish_reason is stripped from the passthrough and recorded on the map so
  the final synthetic text chunk delivers it. Without this, SSE-compliant
  clients stopping at finish_reason drop the guardrailed text — defeating
  the redaction the whole feature exists for. (Greptile P1 twice, Veria.)

Fix #2 — Choice index sort in _process_streaming_transform
  indices/texts_to_check were derived from dict insertion order. For n>1
  streams where choice 1 emits before choice 0, guardrail-returned texts
  aligned to the input order mapped back to the wrong choice indices on
  write-back — wrong text goes to wrong choice. Sort raw_by_index.keys()
  up front so realignment is deterministic. (Bugbot Medium.)

Fix #3 — Cross-chunk pre-tool-call text flush
  With default streaming_sampling_rate=5, text chunks followed by a pure
  tool-call chunk carrying finish_reason='tool_calls' would emit the
  passthrough with finish_reason before any transformed text delta had
  fired. Same failure mode as fix #1 but cross-chunk. Now we flush any
  accumulated text via _round(is_final=False) BEFORE yielding the
  tool-call passthrough. (Greptile P1.)

Fix #4 — Terminator chunk for deferred finish_reason on empty mutated_text
  _build_transform_chunk returned None early when mutated_text_per_choice
  was empty. If a mixed content+tool_call chunk had deferred its
  finish_reason (via fix #1) and the guardrail then suppressed the text
  (empty return), the deferred finish_reason was never delivered. Now on
  is_final=True with empty mutated_text_per_choice, we emit a terminator
  carrying finish_reason per choice from finish_reason_per_choice.
  (Bugbot High.)

Also normalized Optional[X] → X | None across the OSS PR's added surface
via ruff UP045 autofix to keep the strict-rule gate within budget. Pure
mechanical typing style change, no semantic effect.

Regression tests for all four fixes:
- test_mixed_chunk_finish_reason_arrives_after_transformed_text (#1)
- test_text_flush_precedes_tool_call_passthrough (#3)
- test_final_finish_reason_flushed_when_guardrail_suppresses_text (#4)
- test_transform_sends_texts_sorted_by_choice_index (#2)

All fixes reachable only when streaming_transform_mode == 'incremental_diff'
is configured (via _run_incremental_transform_stream) or when a
StreamTransformSink is present (via _process_streaming_transform). Verified
scope-clean: no changes to block_only, non-streaming, pre_call, moderation,
or sibling guardrails.

fix(guardrails): filter Add-Guardrail mode dropdown per provider (#32712)
* fix(guardrails): filter Add-Guardrail mode dropdown per provider

The GET /guardrails/ui/add_guardrail_settings endpoint returned every
GuardrailEventHooks value in one flat supported_modes list, so the Admin
UI rendered pre_mcp_call as a selectable Mode for every guardrail. Saving
Content Filter or Tool Permission with pre_mcp_call then failed with a
400 because those guardrails' server-side supported_event_hooks list
excludes it.

Expose each guardrail's supported hooks as a get_supported_event_hooks
classmethod on CustomGuardrail (mirrors the existing get_config_model
pattern) and have the endpoint iterate guardrail_class_registry to build
a supported_modes_by_provider map. The UI Mode dropdown filters by that
map when the selected provider is known and falls back to the global
list otherwise. __init__ now sources its own supported_event_hooks list
from the classmethod so the two sides can't drift.

Also register BedrockGuardrail, ToolPermissionGuardrail, lakera,
lakera_v2, and presidio in guardrail_class_registry so they participate
in the map (they were previously only in guardrail_initializer_registry
and had no class-registry entry).

Behavior change: guardrails that previously had no supported_event_hooks
declared (aim, javelin, azure/text_moderation, cato_networks,
crowdstrike_aidr, headroom, hiddenlayer, lasso, noma, onyx,
prompt_security, qualifire, repelloai, zscaler_ai_guard, aporia_ai,
lakera_ai, lakera_ai_v2, mcp_jwt_signer, model_armor, presidio) now
validate the configured mode at instantiation. Existing configs where
the mode was silently a no-op will fail at proxy startup with a clear
validation error rather than running as a broken guardrail.

Resolves LIT-4226

* fix(guardrails): add LITELLM_STRICT_GUARDRAIL_MODES escape hatch, preserve current mode in edit form

Address Greptile P1 (startup break) and P2 (edit form UX):

LITELLM_STRICT_GUARDRAIL_MODES defaults to true (raise on unsupported
event_hook, unchanged behavior for the guardrails validated pre-PR).
Setting it to false logs a warning and continues, giving deployments an
opt-out while they fix configs that now surface as errors instead of
silently no-op'ing. Regression test covers both modes.

Edit form now surfaces the currently-saved mode even when it is not in
the filtered per-provider list, so a legacy row (e.g. content_filter
saved with pre_mcp_call before this fix) no longer disappears from the
dropdown; the option renders with a 'not supported by <provider>' note
so the user knows to pick another.

* fix(guardrails): correct audited hook lists, prune stale modes on provider switch, clean form lint

Audited every get_supported_event_hooks classmethod against the hooks
each guardrail's own tests exercise and its handler methods. Five were
too narrow and their tests caught it in CI: rubrik gains pre_call,
presidio gains during_call and pre_mcp_call, prompt_security, onyx and
qualifire gain during_call. The remaining classes match either their
original __init__ declarations or their exercised modes exactly.

Cursor review fixes: the Add form now drops selected modes the new
provider does not support when the user switches providers, so a
pre_mcp_call selection cannot ride along into a provider that rejects
it at save; the edit form handles list-shaped stored modes instead of
treating mode as always a string.

Extracted shared toModeArray and getSupportedModesForProvider helpers
into guardrail_info_helpers so both forms use one implementation, typed
the remaining any usages in both forms, removed nested ternaries, and
committed the ratcheted-down eslint metrics and pruned suppressions

fix(guardrails): show YAML-defined guardrails in the Guardrail Monitor
The /guardrails/usage/{overview,detail,logs} endpoints resolved guardrails only
from the litellm_guardrailstable Prisma table, so guardrails defined in
config.yaml (which live only in IN_MEMORY_GUARDRAIL_HANDLER) were invisible:
detail 404'd, overview omitted them or rendered them as Custom/Guardrail
orphans, and logs missed their logical-name alias.

Add config-owned accessors (list_config_guardrails, get_config_guardrail_by_id)
to the in-memory handler and use them in the usage endpoints, mirroring the
union/fallback already used by list_guardrails_v2 and get_guardrail_info. Also
preserve guardrail_info when storing a config guardrail (type/description were
dropped at initialize time) and read the Prisma-row / dict / LitellmParams
shapes uniformly.

fix(proxy): capture logging_obj before post_call_failure_hook pops it in ModifyResponseException streaming path (#32665)
* fix(guardrails/bedrock): honor disable_exception_on_block by raising ModifyResponseException

The Bedrock-specific GuardrailInterventionNormalStringError predates the
unified guardrails refactor and no proxy code path handles it, so a block
with the flag set surfaced as an uncaught Exception -> HTTP 500 in pre_call
mode and was silently discarded in during_call mode (model call proceeded
in the parallel asyncio.gather; the block hook's data["mock_response"]
mutation happened after route_request had already unpacked kwargs).

Convert the block to ModifyResponseException at the raise site inside
make_bedrock_api_request. That exception is the industry-standard proxy
contract already caught in proxy_server, anthropic_endpoints, response_api
_endpoints, and pass_through_endpoints; it turns into a 200 response with
finish_reason=content_filter and the block message as content, which is
exactly what the flag was documented to yield. Post-call blocks attach
the LLM response to original_response so the synthetic reply reports the
upstream call's real token usage instead of zero.

Deletes the now-orphaned GuardrailInterventionNormalStringError class and
the dead create_guardrail_blocked_response / mock_response plumbing in the
Bedrock hooks; updates the existing tests that had locked in the buggy
contract.

Resolves LIT-4186

* chore(guardrails/bedrock): drop dead str branch in _update_messages_with_updated_bedrock_guardrail_response

Follow-up to the disable_exception_on_block fix. That method used to
receive either a BedrockGuardrailResponse or a plain string (the block
message, when the flag was set). Now that a block always raises
ModifyResponseException before this method runs, the string branch is
unreachable; tighten the type to BedrockGuardrailResponse and delete
the guard.

* fix(guardrails/bedrock): streaming post_call block yields synthetic stream instead of surfacing as SSE 500

Regression from the LIT-4186 refactor: pre-refactor, the streaming
post_call iterator caught GuardrailInterventionNormalStringError locally
and replaced the assembled response with a synthetic content-filter
message, then re-emitted it as chunks via MockResponseIterator. After
the refactor the exception was re-raised as ModifyResponseException,
which async_streaming_data_generator serializes as a proxy 500 error
frame because the SSE response headers are already flushed by the time
the block fires.

Non-streaming paths still let ModifyResponseException propagate to the
endpoint handler (which converts it into a 200). Streaming can't do
that, so keep the local synthesis: on the exception, rebind the
assembled response to a ModelResponse whose single choice carries the
block message as content and finish_reason=content_filter, and let the
downstream MockResponseIterator emit it as chunks. Same shape a
non-streaming block produces.

Adds a mapped-file regression test that mutation-kills the raise
behavior and locks in the synthetic-stream contract.

* fix(guardrails/bedrock): preserve upstream usage on streaming post_call block

Non-streaming post_call blocks report the upstream LLM call's real
token usage via ModifyResponseException.original_response, which the
endpoint handler unwraps through _blocked_response_usage. Streaming
post_call synthesizes its own ModelResponse locally (the exception
can't escape the SSE generator), and previously left .usage unset,
so the client saw accurate billing on non-streaming blocks and zero
on streaming blocks -- silent revenue leak.

Copy the assembled response's .usage onto the synthetic block
response before yielding. Pre-refactor code had the same gap
(create_guardrail_blocked_response never set usage); this is a net
improvement, not a regression fix.

* fix(proxy): capture logging_obj before post_call_failure_hook pops it in ModifyResponseException streaming path

post_call_failure_hook removes litellm_logging_obj from request_data before
iterating callbacks (it's not serialisable). The streaming branch of the
ModifyResponseException handler read it from _data after that call, so it
always received None and CustomStreamWrapper.__init__ crashed with
AttributeError: NoneType has no attribute model_call_details.

Capture it before the hook runs so the streaming path gets a valid object.

* test(proxy): add regression for streaming ModifyResponseException logging_obj capture

Covers the bug where logging_obj was read from request_data after
post_call_failure_hook had already popped it, causing CustomStreamWrapper
to crash with AttributeError.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>

* test(proxy): drive real chat_completion in ModifyResponseException streaming logging_obj regression

The original test inlined the fix pattern (capture before pop) in its
own body rather than calling the actual chat_completion handler in
proxy_server.py, so a revert of the fix left the test passing.
Confirmed via mutation check: reverting the two-line source fix and
re-running left the test green.

Rewrite the test to drive chat_completion directly:
- patch _read_request_body so chat_completion sees the seeded dict
- patch ProxyBaseLLMRequestProcessing.base_process_llm_request to
  raise ModifyResponseException with the same request_data
- patch proxy_logging_obj so post_call_failure_hook mutates the dict
  the way production does (pops litellm_logging_obj)
- intercept CustomStreamWrapper.__init__ and assert logging_obj is
  the non-None object seeded in request_data

Mutation-verified: reverting the source fix now surfaces the exact
production crash inside CustomStreamWrapper's __init__
(AttributeError: NoneType has no attribute model_call_details) rather
than a silently-passing test.

Addresses Greptile P1 on PR #32665.

fix(guardrails): walk Responses-API text taxonomy in shared content helpers (#32542)
* fix(guardrails): walk Responses-API text taxonomy in shared content helpers

Every guardrail sharing litellm/proxy/guardrails/_content_utils.py silently
drops all text on the /v1/responses path. AIM turns it into a loud 422 (
{"error":"No messages in the request"}); every other guardrail (Lakera v2,
Cato, Lasso, Repello, IBM, Azure Content Safety, enterprise secret
detection) scans an empty payload and lets the request through unscanned.

Three defects, all in _content_utils.py:

1. _iter_text_parts_in_content recognised only part.type == "text", but the
   Responses API uses input_text (request) and output_text (assistant).
2. _coerce_input_to_messages gated on "every item has a role key"; any
   Responses input list containing a function_call or function_call_output
   item failed the check and was wrapped as one opaque blob.
3. build_inspection_messages forwarded any role through, including a bare
   tool role missing tool_call_id, which validators like AIM's /fw/v1/analyze
   reject with a schema error.

Fix walks the actual Responses item taxonomy (message, function_call,
function_call_output, bare content parts and strings), recognises
{text, input_text, output_text} everywhere, and coerces any role outside
{system, user, assistant} to user in the outbound inspection payload.

* style: ruff-format changed guardrail files

* test(guardrails): cover function_call_output string form; drop em-dash in new docstring

* fix(guardrails): map function_call_output straight to user role

Avoids ever materialising a schema-invalid bare tool message. The
downstream role-safety coercion in build_inspection_messages still
guards genuinely caller-supplied non-standard roles (developer,
function, custom values); add a regression test covering that path
so the coercion has real coverage after this simplification.

* test(guardrails): pin chat-completions tool-role coercion in build_inspection_messages

* docs(test): soften AIM-specific claims in LIT-4294 test docstrings

Ryan's review flagged that several test docstrings assert AIM's
/fw/v1/analyze validates + rejects specific schema violations. That
behavior is customer-reported in the LIT-4294 writeup, not directly
verified by us. Rephrase to attribute the AIM 422 to the customer's
writeup and describe the underlying constraint as the OpenAI chat
schema; any downstream API that validates against that schema rejects
the same shape.

* refactor(guardrails): move unsupported-role coercion into AIM only

The generic coercion in build_inspection_messages collapsed any role
outside {system, user, assistant} to user for every caller of the
helper. Combined with the pre-existing apply_redacted_messages_back
write-back behavior in Lakera/AIM/Cato, that turned a loud OpenAI 400
on chat-completions tool-message masking into a silent semantic
corruption of the outbound request (role tool with tool_call_id got
rewritten to bare role user, dropping the assistant + tool_calls
sibling).

AIM specifically requires the coercion because its /fw/v1/analyze
validates the payload against the OpenAI chat schema; other guardrails
either do not validate roles or do their own reconstruction. Move the
coercion to AimGuardrail._build_aim_inspection_messages so the shared
helper keeps caller roles intact and no new cross-guardrail role
corruption is introduced. The pre-existing apply_redacted_messages_back
structural flatten remains as separate follow-up work.

function_call_output items still synthesise role user in the shared
helper because they have no natural role field, which is a different
concern from coercing a caller-supplied role.

* refactor(guardrails): preserve role fidelity in shared _content_utils

Shared inspection helpers should extract text and preserve semantic
role signals; role coercion for third-party schema safety stays inside
the guardrail that needs it (AIM).

Three shared-helper changes:
- Bare content-part dicts (input_text/output_text) with an explicit role
  keep it; only role-less parts default to user.
- Responses message items already had their role preserved; the
  behavior is now covered by an explicit test.
- function_call_output items default to role tool (semantic equivalent
  of the chat-completions tool message shape) instead of role user, so
  Responses and chat completions produce symmetric inspection payloads.
  A caller-supplied role on the item is still preserved.

AIM's schema-safe coercion in _build_aim_inspection_messages already
handles the resulting role tool: it collapses to user before the POST
to /fw/v1/analyze so AIM's OpenAI-schema validator does not reject the
bare tool message (no tool_call_id can survive the flatten). Added a
regression test in test_aim.py covering that path.

fix(model_armor): scan MCP tool calls for pre_mcp_call / during_mcp_call modes (#32296)
ModelArmorGuardrail.async_pre_call_hook and async_moderation_hook hardcoded
their inner should_run_guardrail event type to pre_call / during_call. The
central dispatcher already remaps call_mcp_tool -> pre_mcp_call/during_mcp_call
and passes the outer gate, but Model Armor's redundant inner gate then rejected
MCP calls for a guardrail configured with mode pre_mcp_call/during_mcp_call, so
tool-call content was silently skipped.

Remap call_mcp_tool -> pre_mcp_call/during_mcp_call in both hooks, matching the
existing behavior of the noma and cisco guardrails. Adds regression tests
covering both hooks (scan runs on MCP calls, still skipped for chat traffic).

fix(guardrails): send only new messages since last assistant turn to CrowdStrike AIDR (#31974)
Previously, every guardrail request forwarded the full conversation
history to CrowdStrike AIDR. In a multi-turn conversation this means
every prior message gets re-scanned on every new call, even though those
messages were already evaluated in earlier turns.

CrowdStrike AIDR internally has a conversation boundary optimization in
place for just this scenario (ref. <https://aidr-docs.crowdstrike.com/docs/aidr/apis#messages-array-optional---array-of-message-objects-containing-a-conversation-segment-with-the-ai-system>).
However, it is nevertheless wasteful to send so much data to the API
when only a subset of it will be processed. It also risks hitting the
documented 1 MiB request size limit.

So now we filter down to system messages plus either the messages after
the last assistant turn, or the last assistant message itself when that
is what is being guarded. We also preserve the original, full message
history within the guardrail in order to stitch back any
transformations.

* fix(prometheus): bound per-request budget metric emission with a timeout

Wrap the per-request budget-metric gather in asyncio.wait_for so a slow Redis or DB lookup cannot consume the whole LoggingWorker watchdog and get the success-logging event cancelled. On timeout the emission is skipped in isolation; budget gauges are still refreshed by the periodic cron. The timeout is configurable via PROMETHEUS_BUDGET_METRICS_PER_REQUEST_TIMEOUT and defaults to 5.0 seconds, falling back to the default on an invalid value instead of raising

* fix(prometheus): reject non-finite and non-positive budget-metrics timeout env

float() accepts 0, negatives, nan and inf, which bypass the fallback: a value <= 0 makes asyncio.wait_for time out immediately and skip every per-request emission, and inf reintroduces the unbounded wait the timeout was meant to bound. Validate the parsed value is finite and greater than zero before using it, otherwise fall back to the default

* fix: report the blocked LLM response's real token usage (#31217)

When a guardrail blocks a post-call response, the synthetic violation response
reported hard-coded zero usage, discarding the token usage the upstream call
had already consumed.

Fix the root cause rather than re-counting tokens:
- Add an optional `original_response` field to ModifyResponseException.
- The unified guardrail's post-call success hook attaches the blocked LLM
  response to the exception.
- The /v1/messages and OpenAI-format (/v1/chat/completions, /v1/completions)
  block handlers report `original_response.usage` directly. Pre-call blocks
  never invoked the LLM, so usage is zero.

Mock-based tests cover the helper (returns original usage / zero), the success
hook attaching original_response, and the endpoint reporting it end-to-end.

* feat(guardrails): buffer + cleanly terminate streamed responses on block (#31389)

Streaming moderation improvements for the unified guardrail post-call
streaming iterator hook:

- streaming_buffer_until_moderated: withhold all chunks until end-of-stream
  moderation passes, then release the original response (clean) or only the
  block message (blocked) -- the original content is never delivered on a
  block. Snapshot chunks with a shallow list() copy (end-of-stream builds a
  separate assembled response; chunks aren't mutated in place).
- Clean Anthropic SSE on block: synthesize a well-formed termination sequence
  instead of a bare data: {"error": ...} blob that truncates the stream.
  Provider-specific synthesis lives in AnthropicMessagesHandler via
  build_block_sse_chunks (format-agnostic routing stays in the hook).
- Mid-stream blocks continue the in-progress message (close open content
  block, append block message, terminate) rather than emitting a second
  message_start, which clients reject. Standalone envelope only when no chunks
  were sent (buffered path).
- ModifyResponseException imported under TYPE_CHECKING + locally at runtime to
  avoid a module-level cyclic import.

Adds regression tests for buffering (content withheld on block) and mid-stream
continuation (single message_start).

Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix: report real usage on streaming blocks, disable buffered mode for content-rewriting guardrails

- _standalone_block_chunks and _block_continuation_chunks now read real
  token usage from ModifyResponseException.original_response instead of
  hardcoding zero, matching the non-streaming _blocked_response_usage path.
  Shared helper moved to guardrail_translation/utils.py.
- streaming_buffer_until_moderated is now forced off when the guardrail has
  mask_response_content=True, since buffered replay releases the withheld
  original chunks verbatim -- unsafe for a guardrail that rewrites content

feat(guardrails/headroom): add CCR (compress-cache-retrieve) via agentic loop (#31681)
* feat(guardrails/headroom): add CCR (compress-cache-retrieve) support via agentic loop

When Headroom's /v1/compress returns messages containing hash markers
(hash=[a-f0-9]{24}), inject a headroom_retrieve tool into the request.
When the LLM calls that tool, intercept via async_should_run_agentic_loop
and async_build_agentic_loop_plan, call GET /v1/retrieve/{hash} on the
Headroom sidecar, and replay the LLM with the original content as a tool
result -- all transparent to the caller.

* style: run ruff format on headroom guardrail and tests

* fix(guardrails/headroom): detect headroom_retrieve calls in both OpenAI and Anthropic response formats

* test(guardrails/headroom): add test for Anthropic content block format detection in CCR loop

* ci: trigger CI checks

* fix(guardrails/headroom): replace List/Dict with list/dict to fix UP006 ruff violations

* fix(guardrails/headroom): replace except Exception with except ValueError to fix BLE001

* fix(guardrails/headroom): add Responses API output format detection for CCR tool calls

* refactor(guardrails/headroom): extract format-specific helpers to fix C901 complexity

* fix(guardrails/headroom): scope CCR retrieval to hashes produced by current request

Previously any LLM-supplied hash in a headroom_retrieve tool call was
forwarded to the Headroom retrieve API, letting a crafted tool call
fetch arbitrary cached content. Validate the hash against the set
produced by compressing the current request's messages before calling
retrieve.

* fix(guardrails/headroom): track issued hashes server-side, fix Responses API replay shape

Hash validation now also checks an in-memory cache of hashes actually
returned by /v1/compress, not just whether the hash text appears
somewhere in the request's messages. The message-text check alone is
forgeable: an attacker can plant a hash-shaped string in their own
prompt and have it treated as valid.

Responses API follow-up now emits function_call/function_call_output
items keyed by call_id instead of chat-style assistant/tool messages,
since the Responses API does not accept the latter as input. Also
fixes call_id/id field priority when extracting tool calls from
Responses API output, since call_id (not id) is what must match
between the function_call and its output.

* fix(guardrails/headroom): drop redundant quoted type annotations

UP037 flags quotes on annotations that are already lazily evaluated
via `from __future__ import annotations`.

* test(guardrails/headroom): add missing pytest.mark.asyncio decorators

Functional under asyncio_mode=auto, but every other async test in the
file has the decorator for consistency.

* fix(guardrails/headroom): scope CCR hashes per call_id, fix Anthropic replay shape

Two real gaps found in review:

1. The instance-wide issued-hash cache combined with a message-text
   check did not actually scope retrieval to the request that produced
   the hash. A hash issued for request A stays in the shared cache
   until TTL expiry, and the message-text check is satisfied by any
   request whose own messages happen to echo that hash string. Request
   B could plant A's hash in its own prompt and retrieve A's content.

   Fixed by keying the issued-hash cache by litellm_call_id, matching
   the pattern already used in compression_interception: a hash is
   only honored when it was issued under the exact call_id resolving
   for the current request.

2. The Anthropic Messages replay path fell through to the chat-style
   assistant/tool-message builder, which Anthropic does not accept.
   Anthropic requires the tool_use block echoed in an assistant message
   paired with a tool_result block in a user message, keyed by
   tool_use_id. Added a dedicated branch for this shape.

* docs: note proactive API-fragmentation helper convention

Add a bullet to the coding-conventions list: look for or add a shared
helper when logic branches on API surface (chat completions vs
Anthropic Messages vs Responses API), instead of duplicating
format-detection per module.

* fix(guardrails/headroom): fix Anthropic tool-shape detection, extract shared cross-API tool util

Live e2e testing against the real Anthropic API surfaced two bugs the
mocked unit tests couldn't catch because they used MagicMock responses
instead of realistic response shapes:

1. has_headroom_retrieve_tool only recognized OpenAI-shaped function
   tools. By the time an Anthropic Messages response reaches the
   agentic-loop gate, the tool this guardrail injected has already been
   transformed into Anthropic's native shape (type: "custom", top-level
   "name"), so the gate never fired for real Anthropic requests.

2. AnthropicMessagesResponse is a TypedDict, so real responses are
   plain dicts at runtime, not objects with attribute access. The
   extractors and format detectors used bare getattr(), which silently
   returns nothing for dict responses instead of reading the actual
   key.

Extracted the cross-API-surface tool-call extraction and tool-presence
check into litellm/litellm_core_utils/prompt_templates/factory.py
(get_tool_calls_from_response, has_tool_with_name) so this format
fragmentation is handled in one place instead of being duplicated
per-guardrail, and reused the existing repair-aware
parse_tool_call_arguments from common_utils instead of a naive
json.loads. headroom.py now delegates to these shared helpers.

Confirmed live against the real Anthropic API: the retrieve loop now
fires and successfully retrieves the correct hash's content through
the full compress -> tool-call -> retrieve -> replay round-trip.

* fix(guardrails/headroom): fix ruff-strict UP006/I001 budget violations

Use lowercase list/dict generics in the new factory.py tool-call
helpers instead of typing.List/Dict, drop the now-unused Tuple import
in headroom.py, and reorder the new factory import ahead of the
llms.custom_httpx import to satisfy import sorting.

* fix(guardrails/headroom): match Anthropic tools without a type field

Anthropic's documented client tool format is just name + input_schema;
type: "custom" is only one possible value, not a requirement. Match
any non-OpenAI-shaped tool on its top-level name instead of requiring
type == "custom".

fix(presidio): stream SSE output incrementally instead of buffering the whole response (#31503)
The Presidio streaming post-call hooks (_stream_apply_output_masking for
apply_to_output and _stream_pii_unmasking for output_parse_pii) collected every
upstream chunk, reassembled the full completion with stream_chunk_builder at
end-of-stream, ran Presidio over it, then emitted one reconstructed SSE chunk.
Time-to-first-token collapsed to the total generation time and token-by-token
streaming was lost whenever Presidio output handling was enabled. With the
default presidio_filter_scope both, an apply_to_output masking instance is always
created, so even the unmask configuration buffered the stream.

Both paths now transform and forward chunks as they arrive. The unmask path
replaces placeholder tokens per chunk, holding back only the trailing run that
could still grow into a token so a placeholder split across SSE chunks
(<PER + SON_1>) is still rewritten atomically. The mask path emits a prefix only
when masking it in isolation matches the corresponding prefix of masking the
whole buffer, with a lookahead margin still buffered past the cut, so an entity
straddling the cut is detected and held until complete; past
_PRESIDIO_STREAM_MAX_BUFFER the run is bounded without splitting an entity.
Tool-call and legacy function-call argument fragments are accumulated per choice
and transformed once the choice closes, content is buffered independently per
choice index for correct n>1 streaming, raw Anthropic SSE bytes and /v1/responses
events pass through with any held content flushed first so events never reorder,
and a masking error redacts only the affected chunk (fail closed, keeping
finish_reason) while the stream continues.

* feat(guardrails): expose streaming knobs on generic_guardrail_api

Wire streaming_end_of_stream_only and streaming_sampling_rate through
optional params, initialize_guardrail, and get_config_model so the
generic guardrail API participates in UnifiedLLMGuardrails streaming
checks with configurable cadence and end-of-stream-only mode.

* fix(guardrails): use builtin type[] in get_config_model return

Avoids a new UP006 violation that tripped the ruff strict-rule budget
gate on the PR lint job.

* fix(guardrails): default optional streaming knobs to None

Non-None Pydantic defaults on GenericGuardrailAPIOptionalParams made
_get_config_value treat unset nested fields as explicit values, which
shadowed top-level litellm_params streaming flags whenever any other
optional_params key was present. Real defaults stay in the constructor.

* fix(guardrails): address review nits on generic_guardrail_api streaming

Validate streaming_sampling_rate >= 1 in the constructor and Pydantic
optional_params (ge=1), and add /v1/responses streaming coverage through
the unified post-call hook so Responses API usage is exercised alongside
chat completions.

* fix(guardrails): read nested streaming config from dict optional_params

Guardrail API/UI delivers optional_params as a plain dict, so getattr was
silently ignoring streaming_sampling_rate and streaming_end_of_stream_only.
Handle both dict and model shapes in _get_config_value with regression tests.

fix(guardrails): scan file and document attachments with Model Armor (#31655)
The Model Armor guardrail only sent text extracted from user messages to
sanitizeUserPrompt, so harmful content inside attached PDFs, Office docs,
and CSVs reached the LLM unscanned. A file-only message had no extractable
text, so the pre-call and moderation hooks returned early and the document
was never submitted to Model Armor at all.

Wire inline document/file scanning into async_pre_call_hook and
async_moderation_hook. extract_file_attachments walks message content blocks
(OpenAI type:file file_data and Anthropic type:document source), decodes the
base64 bytes, maps the MIME type to a Model Armor byteDataType, and skips
remote URLs, bare file_id references, oversize files past the 4 MB limit, and
unsupported types. Each attachment is sent through the byte API and a
MATCH_FOUND blocks the request before it reaches the LLM.

feat(guardrails): add headroom guardrail for message compression (#31407)
* feat(guardrails): add headroom guardrail for message compression

Adds a headroom guardrail that compresses request messages via POST
/v1/compress before they reach the LLM. The guardrail implements
apply_guardrail so it runs on the unified guardrail path; it receives
pre-built structured_messages (OpenAI format) from the translation
layer, calls the headroom compression service, and returns the
compressed messages as structured_messages.

Set x-headroom-bypass: true on the request to skip compression.

Also adds structured_messages write-back support to the OpenAI and
Anthropic translation handlers: when apply_guardrail returns
structured_messages, those are written to data["messages"] directly
(OpenAI) or reverse-translated via anthropic_messages_pt (Anthropic)
instead of falling through to the existing text-patch path. This is a
prerequisite for any guardrail that needs to replace the full message
list rather than patch individual text spans.

feat(guardrails): make the Generic Guardrail resilient to built-in tools and errors (adopted from #31286) (#31461)
Some checks failed
GitHub Actions Security Analysis / zizmor (push) Waiting to run
LiteLLM Rust / rustfmt, clippy, test (push) Has been cancelled
* fix(guardrails): stop Generic Guardrail API 500 on built-in tools

Requests carrying built-in tools (code_interpreter, file_search, ...) crashed
the Generic Guardrail with a 500. GenericGuardrailAPIRequest.tools validated
each tool against ChatCompletionToolParam, whose base TypedDict requires a
function block, so a tool like {"type": "code_interpreter"} raised a Pydantic
ValidationError before the request was ever sent.

Type the field with a permissive GuardrailToolParam model (type required,
extra=allow) so built-in tools validate and their config is forwarded to the
guardrail intact instead of being stripped.

* feat(guardrails): add complete fail-open (fail_on_error) to Generic Guardrail

The Generic Guardrail already honored unreachable_fallback, which fails open
only on network-unreachable errors. This wires up the existing generic
fail_on_error config (so far implemented only by Model Armor) so that
fail_on_error=false degrades any guardrail error to a critical-log warning and
lets the request proceed as if the guardrail were absent.

Only a valid guardrail response can act: a parsed BLOCKED decision still raises,
while endpoint errors, malformed responses, and internal serialization or
validation errors all fall through when fail_on_error=false. To cover that last
class, the request construction now runs inside the protected block, so the kind
of validation error that previously surfaced as a 500 is caught here too.

Defaults to true (fail closed), matching today's behavior; turning it off is an
explicit availability-over-security choice and is logged at critical level on
every bypass.

* test(guardrails): cover fail_on_error on the response path

The existing fail_on_error tests all drive the request path. Add response-path
(input_type=response) coverage: an endpoint error proceeds unchanged under
fail_on_error=false, and a valid BLOCKED decision still raises. Guards against a
future regression that special-cases input_type in the error handling.

* style(guardrails): black-format the fail-open guard expression

CI runs black (line-length 88) over litellm/; the unreachable_fail_open
assignment exceeded it. Wrap it to satisfy the formatter.

* fix(guardrails): validate tools into GuardrailToolParam at the call site

Changing the request field to List[GuardrailToolParam] left the construction
passing List[ChatCompletionToolParam] (list is invariant), which tripped the
basedpyright reportArgumentType budget gate. Validate each tool explicitly,
which is what Pydantic did implicitly, so the types line up with no Any or
suppression and the serialized payload is unchanged.

* fix(guardrails): make fail-open log message accurate for non-network errors

The fail-open path is now shared by fail_on_error, so it fires for any guardrail
error, not just unreachability. The log said 'unreachable' even for an HTTP 400
or a malformed response; reword to 'error' (the status code and exception are
already logged). Addresses the Greptile review's only finding.

* fix(guardrails): align GenericGuardrailAPIResponse.tools with GuardrailToolParam

Greptile flagged that the request side moved to GuardrailToolParam but the
response side still annotated tools as List[ChatCompletionToolParam], which
mandates a function block and contradicts the new built-in-tools support.
Update the response annotation (and the now-unused import) so the two sides
agree. Runtime is unchanged; from_dict stores the raw dicts and the only
consumer assigns through to GenericGuardrailAPIInputs without inspecting
the elements.

OpenAI GPT-5 models require max_completion_tokens >= 16.
Health checks were using 5 (proxy/health_check.py) and 10

Fixes #23836

* fix: increase health check max_tokens from 5 to 16 (#23836) (#26610)

GPT-5 models enforce a minimum of 16 for max_output_tokens. The current
default of 5 still causes health checks to fail for these models. Bump
the non-wildcard default to 16 — the smallest value that satisfies all
known provider minimums while keeping health checks lightweight.

Also tightens the wildcard test assertion from a weak disjunctive check
to strict key-absence.

* fix: make Bedrock Mantle Responses routing data-driven per model (#30700)

* Make Bedrock Mantle Responses routing data-driven per model

Route Bedrock Mantle models to the native Responses API based on each
model's price-map capability signal instead of a hardcoded model-name
heuristic, and derive the OpenAI-compatible base path segment per model.

Responses dispatch now selects the native config when the model advertises
responses support (/v1/responses in supported_endpoints, or mode=responses),
both overridable via register_model and proxy model_info. This enables
native Responses for gpt-oss-120b/20b and the gemma-4 family while keeping
chat-only models (gpt-oss safeguard, nvidia, mistral, ...) on the existing
chat-completions emulation. Capability is per-model, so gpt-oss-120b routes
natively while gpt-oss-safeguard-120b does not despite sharing the gpt-oss
substring.

The wire path is a separate concern, driven by the existing
use_openai_responses_path flag rather than a model-name match: gpt-5.x and
gemma-4-* on /openai/v1, everything else (incl. gpt-oss) on /v1. The chat
config now derives its base from the same flag, fixing gemma-4
chat-completions requests that previously went to /v1 instead of /openai/v1.

Cost maps: add supported_endpoints to the gpt-oss entries (responses for the
non-safeguard variants, chat-only for safeguard) and supported_endpoints +
use_openai_responses_path to all three gemma-4 entries.

* Address review: move capability helper into bedrock_mantle package

Move the Responses capability check out of utils.py into
litellm/llms/bedrock_mantle/common_utils.py as mantle_supports_responses,
alongside its companion wire-path helper mantle_base_segment. Both are now
pure functions of (model, model_cost): the price-map mode/supported_endpoints
read replaces the get_model_info call, so the rules are unit-testable without
patching global state and the Bedrock Mantle package is self-contained.

Use str | None instead of Optional[str] on the new signatures to satisfy the
ruff UP045 strict-rule gate. Add direct unit tests for both helpers.

Fix test_register_model_restore_undoes_existing_key_overwrite: gpt-oss-120b
now legitimately supports Responses, so it can no longer be the
"None after restore" vehicle; use the chat-only safeguard variant, which
isolates the register/restore effect from the model's own capability.

* fix(proxy): fail fast on non-PostgreSQL DATABASE_URL instead of hanging on startup (#30366)

* fix(proxy): fail fast on non-PostgreSQL DATABASE_URL instead of hanging on startup

LiteLLM's Prisma datasource is pinned to provider = 'postgresql', so a sqlite:// or mysql:// DATABASE_URL can never connect.

Today that surfaces as an opaque startup stall where the port never binds, and a separate 'DB not connected' 500 on /key/generate when no DATABASE_URL is set at all leaves operators guessing what to configure.

Validate the DATABASE_URL / DIRECT_URL scheme in run_server before any Prisma call and exit with an actionable message naming the unsupported scheme.

Also reword CommonProxyErrors.db_not_connected_error to tell the operator to set DATABASE_URL to a postgresql:// connection string.

* fix(dashscope): treat an explicit 0.0 tier cost as a real price, not missing (#30653)

The tiered cost calculator resolved a tier's per-token cost with
`tier.get(cost_key) or tier.get(fallback_cost_key, 0)`. Because `or`
short-circuits on any falsy value, a tier that legitimately prices a
component at 0.0 (e.g. a free-cache-read tier with
cache_read_input_token_cost: 0.0, or a free-reasoning tier) is treated
as missing and silently billed at the full fallback rate
(input_cost_per_token / output_cost_per_token).

The flat-pricing path in the same module already handles this correctly
with an `is None` guard. Resolve tier costs through a small helper that
mirrors it, so 0.0 is honored at both the in-range and overflow sites.

No shipped model currently has a 0.0 tier cost, so this is a latent
defect; the fix makes the tiered path consistent with the flat path and
prevents over-charging the first time such a tier appears. Adds unit
tests covering the in-range and overflow paths, and drops an unused
import flagged by ruff in the touched test file.

In the messages->chat/completions bridge, translate_anthropic_tools_to_openai
merged every non-mapped tool key into the function parameters dict. The
Anthropic tool 'type' (e.g. 'custom') thus overwrote parameters.type ('object'
-> 'custom'), and providers reject it ('custom' is not a valid JSON-Schema type).
Exclude 'type' from the passthrough. Fixes #30557.

* fix(proxy): stop IAM-refresh engine restart from cascading reconnects (#29176) (#30183)

An RDS IAM token refresh recreates the Prisma client, which SIGKILLs the
running query-engine and spawns a new one. That planned kill was
indistinguishable from a crash, and three reconnect paths used two
uncoordinated locks, so a single refresh triggered a cascade of engine
kill/respawn cycles:

  1. `_safe_refresh_token` (holds `_reconnection_lock`) -> recreate -> kill old
     engine, spawn new one.
  2. The engine-death watcher sees that kill, assumes a crash, and calls
     `attempt_db_reconnect(force=True)` (a different lock,
     `_db_reconnect_lock`) -> recreate again -> kills the fresh engine.
  3. In-flight queries failing during the swap are classified as transport
     errors and trigger their own `attempt_db_reconnect` -> recreate again.

Fix coordinates planned restarts across the wrapper and the watcher:

  - PrismaWrapper records the old engine PID in `_expected_engine_deaths`
    before killing it; all four watcher death-detectors (waitpid thread,
    pidfd, already-dead probe, os.kill poll) consume that PID and skip the
    reconnect instead of treating it as a crash.
  - `recreate_prisma_client` now serializes through `_reconnection_lock` and
    bumps a monotonic `_engine_generation`. Callers pass `expected_generation`
    as an optimistic-lock token, so racing/cascading recreates collapse into a
    single restart (losers no-op). This closes the two-lock gap.
  - The direct reconnect path probes the writer with SELECT 1 before
    recreating; a healthy connection (e.g. engine already replaced by a
    refresh) skips the recreate entirely.
  - `_safe_refresh_token` coalesces: it skips when the current token still has
    more than the refresh buffer of runway, so stacked triggers (proactive
    loop + __getattr__ fallback) don't each restart the engine. An
    `on_engine_replaced` hook re-arms the watcher on the new PID.

RoutingPrismaWrapper forwards `expected_generation` and skips recreating the
reader when the writer recreate was skipped.

* feat(bedrock): support file content retrieval for batch output files (#30595)

Implements transform_file_content_request and transform_file_content_response
in BedrockFilesConfig so GET /v1/files/{id}/content works for Bedrock batch
files. The request transform resolves the file id (direct s3:// URI or base64
unified id) to its S3 object, validates bucket and key prefix against the
server-configured bucket, and SigV4-signs an S3 GetObject using the same
credential and region resolution as the existing upload path. The credential
and region params are validated into a typed model at the boundary, so the only
untyped values left are the botocore signing primitives.

Also fixes the proxy managed-files path: CredentialLiteLLMParams now carries
s3_bucket_name (previously dropped when building deployment credentials) and
the managed-files hook passes the deployment credential snapshot when routing
afile_content, so unified-id content retrieval works with per-model bucket
config instead of only the AWS_S3_BUCKET_NAME env var.

Preserves managed-file access control: the proxy file-content endpoint now
rejects raw cloud-storage ids (s3://, gs://), which would otherwise skip the
owner/team check that only runs for unified ids and let a caller read another
tenant's batch output by its object key. Managed outputs are reachable only
through their unified file id. The afile_content "not found" error now reports
the caller's unified id rather than the resolved internal S3 URI.

* fix(oci): make Cohere {{trace}} judges work (tool param types + agentic tool-calling continuation) (#30646)

get_span) take an attributes_to_fetch array. The lowercase builtins list/dict
are accepted; only the bare "List" 500s ("Dict" happens to be tolerated, but
both are lowercased for consistency).

Verified live against us-chicago-1 (cohere.command-a-03-2025 and
command-latest). Adds a unit regression on the transformed parameterDefinitions
plus a gated integration test exercising an array-param tool end to end.

* fix(oci): make Cohere agentic tool-calling continuation work

Two bugs broke the OCI Cohere tool-calling loop that MLflow {{trace}} judges
drive once a tool has been executed and its result is fed back.

Request side: litellm pulled the last user message into the top-level `message`
and emitted the tool result as a TOOL entry in chatHistory. OCI rejects that
("cannot specify message if the last entry in chat history contains tool
results"), and an empty message alone is rejected too ("message must be at least
1 token long or tool results must be specified"). OCI carries the current turn's
results in a dedicated top-level `toolResults` field. The Cohere transform now
sends an empty message, keeps the user turn in chatHistory, and puts the results
in `toolResults`, matching the langchain-oracle reference. Tool results are no
longer represented as chatHistory entries.

Response side: tool-grounded answers come back with citations carrying
`documentIds` (camelCase) and no `document_ids`, which made the required
`CohereCitation.document_ids` field fail validation and sink the whole response
parse. Those citations are never surfaced, so the field (and CohereSearchQuery's
generation_id) is now optional.

Verified live against us-chicago-1 (cohere.command-a-03-2025 and command-latest),
single and multi-round tool loops. Adds unit regressions on the transformed
request shape and on citation parsing, plus gated integration tests for the
continuation.

* feat: integrate Repelloai Argus guardrail (#30673)

* feat(guardrails): add RepelloAI Argus guardrail integration (#1)

* feat(guardrails): add RepelloAI Argus guardrail integration

Add a new guardrail hook backed by RepelloAI Argus, with dashboard-managed
asset policies enforced via an asset_id and X-API-Key auth.

* fix(guardrails): harden RepelloAI Argus guardrail

- scan streaming responses on output (was bypassing the guardrail)
- log blocked verdicts as guardrail_intervened instead of success
- treat auth/config errors (401/403/404/422) as misconfiguration that
  always blocks, not a fail-open-able unreachable error
- default unreachable_fallback to fail_closed and read it directly;
  block on unknown/malformed verdicts so an API change can't silently
  disable enforcement
- type unreachable_fallback as a Literal, drop the duplicate config model,
  expose unreachable_fallback in the config schema, and stop leaking the
  raw provider response / exception strings to the client

* fix(guardrails): address RepelloAI Argus review feedback

- support ARGUS_API_KEY (with REPELLOAI_API_KEY fallback)
- make asset_id required in the config model
- normalize unreachable_fallback so only fail_open opens; block on 400 misconfig
- correct the shared unreachable_fallback field description

* docs(guardrails): add RepelloAI Argus docs page and dashboard listing

- add docs page covering config, env vars, modes, verdicts, failure semantics
- list RepelloAI Argus in the Guardrail Garden with provider/logo mappings
- add a regression test for the provider logo and display-name resolution

* fix(guardrails): keep RepelloAI asset_id optional in config model

A required asset_id leaked onto the shared LitellmParams (which inherits
RepelloAIGuardrailConfigModel), breaking validation for every other
guardrail. Keep it optional like sibling models; the guardrail __init__
still raises when asset_id is missing, which is the real enforcement.

* Add comment for last user turn scanning

* feat(guardrails): harden repelloai scanning

* feat(guardrails): expand repelloai scanning to include tool definitions

Add extraction of tool definitions and tool call arguments to the RepelloAI
guardrail scanning. Improves detection coverage by including function schemas
and parameters in the prompt sent to the guardrail service. Also captures
detailed error responses in logs and adds guardrail header to streaming responses.

* refactor(guardrails): fix and harden repelloai schema text extraction

- Fix duplicate text in _iter_schema_text: previously all dict values were
  re-queued onto the stack even after scalar/list keys were already extracted
  explicitly, causing names/descriptions to appear twice in the scanned prompt
- Extract schema key frozensets to module-level constants so they are not
  reconstructed on every call
- Change _iter_schema_text from @classmethod to @staticmethod (cls unused)
- Narrow _call_analyze stage param from str to Literal["prompt", "response"]
- Add HttpxResponse type annotation to _raise_for_config_error
- Add LLMResponseTypes annotation to async_post_call_success_hook response param

* fix(guardrails): resolve pyright type errors in repelloai guardrail

- Narrow async_handler.post return from Response|None to Response with
  explicit None guard before calling raise_for_status/json
- Fix list comprehension returning str|None by switching to explicit loop
  with isinstance guard so pyright tracks the narrowing
- Cast model_dump() result to Dict since hasattr does not narrow object
  type in pyright

* fix(guardrails/repello): include Responses API instructions field in prompt scan

The /v1/responses top-level `instructions` field was not included in
_extract_prompt_text, allowing a caller to bypass guardrail policy checks
by putting blocked content in `instructions` while keeping `input` benign.

* feat: add api_key to config model and read prompt from data dict

* fix(guardrails/repello): plug input_text and tool-call response bypass gaps

Responses API input content parts with type 'input_text' were silently
dropped by build_inspection_messages (which only handles type='text'),
allowing callers to send blocked content via that path without triggering
the pre-call scan. Fix: add _extract_input_text_parts to RepelloAIGuardrail
and call it when walking the Responses API input messages.

Post-call scanning skipped responses whose choices contained only tool_calls
or function_call (message.content=None), letting models put blocked output in
function arguments undetected. Fix: _extract_chat_completion_text now calls
_extract_tool_call_args_from_message on each choice message.

Also replace typing.Dict/List with builtin dict/list to clear TID251 strict
ruff violations introduced by this file.

* fix(guardrails/repello): scan Responses API function_call output arguments

Output items with type 'function_call' in a /v1/responses response were
skipped by _extract_responses_api_text; only 'message' items were walked.
A model could return blocked content in function_call.arguments undetected.
Now extract arguments from function_call output items before scanning.

* refactor(guardrails/repello): clean up typing and remove lint-any workarounds

- Replace Optional[X]/Union[X,Y] with X|None/X|Y union syntax throughout
- Use dict[str, object] instead of bare dict in all signatures
- Remove **kwargs from __init__; declare guardrail_name, event_hook, default_on explicitly
- Replace getattr(litellm_params, ...) with direct attribute access now that LitellmParams inherits RepelloAIGuardrailConfigModel
- Add _event_hook_from_mode() to convert str|list[str]|Mode to typed GuardrailEventHooks
- Use TypeAdapter.validate_json() instead of response.json() + manual dict construction
- Add _is_object_dict/_is_object_list TypeGuard helpers to narrow object types without Any
- Remove cast() workarounds and typed intermediate variables that existed only for the now-removed lint-any CI check
- Drop _AddLiteLLMCallback Protocol; budget has sufficient slack for the one reportUnknownMemberType
- Fix GuardrailConfigModel missing type arg: GuardrailConfigModel[BaseModel]

* fix(guardrails/repello): suppress LIT007 on TypeGuard helpers and add streaming scan-skip warning

- Add guard-ok suppressions to _is_object_dict and _is_object_list to satisfy the LIT007 hard-zero budget gate
- Emit verbose_proxy_logger.warning when the streaming hook finds no inspectable text after assembly, matching observability of pre/post hooks

* refactor: modifications for lint check

* feat: add Pinstripes as an OpenAI-compatible provider (#30567)

* feat: add Pinstripes as an OpenAI-compatible provider

Pinstripes (https://pinstripes.io) is an OpenAI-compatible inference
provider serving open-source models (GLM-4.5-Air, Qwen3, DeepSeek, etc.)
with per-token pricing and no subscriptions.

Changes:
- `litellm/llms/openai_like/providers.json`: register pinstripes with
  base_url, api_key_env, and max_completion_tokens→max_tokens mapping
- `litellm/types/utils.py`: add `PINSTRIPES = "pinstripes"` to LlmProviders
- `litellm/constants.py`: add to openai_compatible_providers and
  openai_compatible_endpoints lists
- `litellm/litellm_core_utils/get_llm_provider_logic.py`: auto-detect
  provider when api_base is "https://pinstripes.io/v1"
- `provider_endpoints_support.json`: document supported endpoints
- `tests/`: 7 unit tests covering provider registration, resolution,
  URL auto-detection, api_base override, and Router config

Usage:
    import litellm
    response = litellm.completion(
        model="pinstripes/ps/glm-4.5-air",
        messages=[{"role": "user", "content": "Hello"}],
        api_key=os.environ["PINSTRIPES_API_KEY"],
    )

* fix(anthropic-messages): apply cache_control_injection_points on /v1/messages path (#30341)

cache_control_injection_points was only consumed by the chat/completions
prompt-management hook; on the native Anthropic /v1/messages path it was
forwarded unused, so deployment-level cache injection was silently dropped
(cache_creation_input_tokens stayed 0 for Anthropic-native clients).

Add AnthropicCacheControlHook.apply_to_anthropic_messages_request to inject
cache_control at block level for system / tools / message locations (the only
forms /v1/messages accepts), wire it into the native anthropic_messages
handler, and pop the param so it does not leak upstream as an unknown field.
A {location: message, role: system} config is redirected to the top-level
system prompt so the same YAML works on both endpoints.

Injection respects Anthropic's 4-block cache_control limit shared across
system, tools, and messages: client-supplied markers count toward the cap and
are never overwritten, a slot is reserved per Bedrock tool_config point, and
injection stops once the budget is exhausted. Locations this path cannot
represent (tool_config) are forwarded downstream instead of being silently
consumed, mirroring get_chat_completion_prompt's remaining_points pass-through.

* fix(proxy): release budget reservation when a request is cancelled mid-flight (#30522)

* fix(proxy): release budget reservation on cancel when no chunk was delivered

The pre-call budget reservation increments the cross-pod spend counter by a
request's worst-case cost, then reconciles it on success (cost callback) or
error (failure hook). A client disconnect or timeout cancels the request and
surfaces as CancelledError / GeneratorExit, which neither path catches, so the
reservation leaks. Under a retry storm the leaked holds accumulate, pin the
counter above real spend, and return spurious 429 "Budget has been exceeded" to
keys whose spend is far below budget; the counter only recovers when its TTL
lapses, so the failure is intermittent and self-healing.

Release the reservation in async_streaming_data_generator (which the Anthropic
and Google SSE generators delegate to) on the (CancelledError, GeneratorExit)
path, alongside the existing max_parallel_requests release. release_budget_
reservation_on_cancel runs under asyncio.shield so it completes despite the
in-progress cancellation, is guarded by the reservation's finalized flag, and
swallows a failing release so it cannot replace the in-flight cancellation.

The refund is gated on whether a chunk reached the client. The flag is set
immediately before the yield, after the slow-path hook await: an async generator
suspends at the yield, so a GeneratorExit on disconnect after a delivered chunk
sees it True (keep the hold), while a cancellation during the slow-path await
leaves it False (refund, nothing sent). A non-streaming cancellation delivers
nothing and a completed non-streaming response is reconciled by the success
callback, so neither needs a release here.

* fix(proxy): reconcile a cancelled reservation to input cost, not zero

A streaming request cancelled before the first chunk previously reconciled its
reservation to zero and finalized it. But by the time the generator is
consuming the response the provider call was already dispatched, so the input
tokens were billed even though no chunk reached the client, and the
success/failure cost callbacks are skipped on cancellation. Refunding to zero
let a caller send an expensive request and abort pre-token to dodge the input
charge.

Compute the request's input-token cost at reservation time and reconcile the
cancelled reservation to it instead of zero. The worst-case output portion of
the reservation is still released (so a legitimate mid-flight cancellation no
longer pins the counter and 429s the key), while the input the provider already
processed is charged.

* fix(caching): encode object name in GCS cache GET path (#30378)

GCS cache reads always missed when gcs_path was set. The GET methods
interpolated the object name directly into the URL path, while the GCS
JSON API requires it to be URL-encoded (a "/" must be sent as %2F).

With gcs_path configured the object name is "<prefix>/<sha256>", so the
raw slash produced a malformed object path and GCS returned 404. httpx
does not raise on 4xx, so the status_code == 200 check fell through and
get/async_get returned None, silently missing on every read. Without
gcs_path the key has no slash, which is why this went unnoticed.

Wrap the object name with urllib.parse.quote(..., safe="") in get_cache
and async_get_cache. Apply the same encoding to the name= query
parameter in set_cache and async_set_cache so the key written matches
the key read back.

Adds regression tests asserting the GET path and SET query are encoded
(%2F) when gcs_path is set, for both sync and async paths; these fail on
the unpatched code.

* fix(proxy): stop IAM-refresh engine restart from cascading reconnects (#29176) (#30183)

An RDS IAM token refresh recreates the Prisma client, which SIGKILLs the
running query-engine and spawns a new one. That planned kill was
indistinguishable from a crash, and three reconnect paths used two
uncoordinated locks, so a single refresh triggered a cascade of engine
kill/respawn cycles:

  1. `_safe_refresh_token` (holds `_reconnection_lock`) -> recreate -> kill old
     engine, spawn new one.
  2. The engine-death watcher sees that kill, assumes a crash, and calls
     `attempt_db_reconnect(force=True)` (a different lock,
     `_db_reconnect_lock`) -> recreate again -> kills the fresh engine.
  3. In-flight queries failing during the swap are classified as transport
     errors and trigger their own `attempt_db_reconnect` -> recreate again.

Fix coordinates planned restarts across the wrapper and the watcher:

  - PrismaWrapper records the old engine PID in `_expected_engine_deaths`
    before killing it; all four watcher death-detectors (waitpid thread,
    pidfd, already-dead probe, os.kill poll) consume that PID and skip the
    reconnect instead of treating it as a crash.
  - `recreate_prisma_client` now serializes through `_reconnection_lock` and
    bumps a monotonic `_engine_generation`. Callers pass `expected_generation`
    as an optimistic-lock token, so racing/cascading recreates collapse into a
    single restart (losers no-op). This closes the two-lock gap.
  - The direct reconnect path probes the writer with SELECT 1 before
    recreating; a healthy connection (e.g. engine already replaced by a
    refresh) skips the recreate entirely.
  - `_safe_refresh_token` coalesces: it skips when the current token still has
    more than the refresh buffer of runway, so stacked triggers (proactive
    loop + __getattr__ fallback) don't each restart the engine. An
    `on_engine_replaced` hook re-arms the watcher on the new PID.

RoutingPrismaWrapper forwards `expected_generation` and skips recreating the
reader when the writer recreate was skipped.

Before substring search was added (commit 33bd570d5e), /key/list matched user_id
and key_alias exactly. That change made admin-authenticated calls substring-match
by default, breaking the prior contract: a caller passing an exact user_id as an
access filter (e.g. an integration scoping to one user with an admin key) then
received other users' keys -- user_id="alice" also returned "alice2",
"alice-test", etc. This is a cross-user key disclosure.

Make substring matching opt-in via a new admin-only substring_matching=true query
param; default to exact, restoring the prior behavior. The dashboard search box
(keyListCall) passes the flag so partial search still works. Non-admins remain
exact and scoped to their own keys.

Updates the proxy-behavior key_alias test to opt in and adds an exact-by-default
guard; adds list_keys unit coverage for the opt-in gate.

feat(guardrails): surface OpenAI moderation violation_categories on guardrail traces (#30659)
The OpenAI moderation guardrail (and the ai-platform-moderation guardrail
built on it) stamped the whole moderation model response into the guardrail
trace as guardrail_response. That blob carries the full category_scores map
plus categories and category_applied_input_types, which on OTEL backends that
index span attributes (for example ELK, which caps indexed attribute values at
1024 chars) overflows the limit and gets truncated, so the violated categories
cannot be reliably searched.

Extract the flagged category names from the moderation response and pass them
through tracing_detail to add_standard_logging_guardrail_information_to_request_data,
mirroring the Bedrock hook. Both the legacy and v2 OTEL integrations already
read violation_categories off the standard logging guardrail information and
emit it as a short, queryable guardrail_violation_categories attribute, so
dashboards can group and filter by violation category without parsing the large
guardrail_response blob.

chore: litellm oss staging160626 (#30527)
* feat(ui): gate "Default Credentials" hint on /ui/login behind env flag (#30234)

Adds LITELLM_HIDE_DEFAULT_CREDENTIALS_HINT (and an equivalent
general_settings.hide_default_credentials_hint) that suppresses the
"By default, Username is admin and Password is your set LiteLLM Proxy
MASTER_KEY" info card rendered on /ui/login and /fallback/login.

Motivation: in production deployments operators set UI_USERNAME /
UI_PASSWORD (or SSO), and the hardcoded hint becomes factually
incorrect and is flagged by security scanners (Tenable WAS plugin
114625) as information disclosure. There is currently no way to
suppress it without forking the dashboard.

Behaviour:
- Default is unchanged (hint shown), so existing deployments are
  unaffected.
- New field hide_default_credentials_hint on the well-known UI config
  endpoint, populated from the env var or general_settings.
- LoginPage.tsx conditionally renders the Alert based on the flag.

* fix(router): clean pattern_router state on upsert/delete (#29601)

* fix(router): clean pattern_router state on upsert/delete

PatternMatchRouter.add_pattern was append-only, and neither Router.upsert_deployment nor Router.delete_deployment removed the existing entry. Rotated-out api_keys stayed in the routing rotation for wildcard deployments (model_name with `*`) until proxy restart, silently defeating key rotation as an admin operation. The same leak applied to provider_default_deployment_ids and per-team pattern routers, and the patterns list grew unboundedly on every edit

* test(router): direct unit tests for _remove_deployment_from_wildcard_state

router_code_coverage.py greps test files for AST Call nodes and flagged
the helper as untested because the existing coverage only exercised it
transitively through upsert/delete. Adds two direct tests that pin the
helper's contract (cleans across global pattern router, per-team
routers with empty-router pop, and provider_default_deployment_ids;
noop on falsy model_id)

* fix(router): address Greptile review on pattern_router cleanup

Widen PatternMatchRouter.remove_deployment annotation to Optional[str];
the implementation already handles None via the falsy guard and the
unit test exercises it directly.

Move _remove_deployment_from_wildcard_state up one level in
upsert_deployment so it runs whenever the prior deployment is on the
router, not only when the model_id is present in the fast-mapping
index. The scenario is currently unreachable (get_deployment shares
the same index), but the cleanup is idempotent so this is defensive
against any future divergence between those code paths.

* fix(router): widen _remove_deployment_from_wildcard_state to Optional[str]

Moving the call out of the inner `deployment_id in deployment_fast_mapping`
block in the previous commit lost mypy's narrowing of `deployment_id`
from Optional[str] to str, tripping the lint CI. The helper already
handles None via its falsy guard, so widening the annotation matches
the actual contract.

* fix(router): make delete_deployment wildcard cleanup symmetric with upsert

After the previous commit moved _remove_deployment_from_wildcard_state out
of the inner index-map guard in upsert_deployment, delete_deployment was
still calling it only inside `if deployment_idx is not None`. Greptile
flagged the asymmetry: under a desynced index_map, delete would silently
leave the stale wildcard credential in pattern_router.

Moves the cleanup call to the top of the try block, mirroring the upsert
path. Cleanup is idempotent so the change is a no-op on the happy path.
Adds a regression test that simulates the desync by removing the entry
from model_id_to_deployment_index_map and asserts delete still clears
pattern_router.

* fix(pricing): add 1h cache-write cost for Anthropic Sonnet 4.5/4.6 (#30474)

The native anthropic claude-sonnet-4-5/4-6 price-map entries were missing
cache_creation_input_token_cost_above_1hr (and the >200K long-context

* fix(proxy): cancel upstream gemini request and release httpx connection on client disconnect (#30075)

* fix(proxy): cancel upstream gemini request and release httpx connection on client disconnect

- add _check_request_disconnection to common_request_processing; wrap llm_call
  as asyncio.Task so it can be cancelled; catch CancelledError and raise
  HTTPException(499) when client disconnects before LLM responds (non-streaming path)

- pass raw httpx.Response into ModelResponseIterator in make_call/make_sync_call
  so the iterator holds a reference to the underlying connection

- implement ModelResponseIterator.aclose() and .close(): close the line iterator
  then explicitly call response.aclose()/response.close() to release the httpx
  connection when the client drops mid-stream; errors are debug-logged, not raised

- add tests for _check_request_disconnection (cancels task, graceful on exception,
  does not cancel when client stays connected) and base_process_llm_request 499
  behavior; add TestModelResponseIteratorCleanup verifying aclose/close propagation
  through CustomStreamWrapper

* fix(proxy): record 499 on streaming disconnect and cancel orphaned gather tasks

Wire streaming generator cleanup to log client_disconnected with error_code 499
in spend logs, cancel pending during_call_hook tasks when the LLM call is
cancelled on disconnect, and align the 600s poll limit comment with proxy_server.

* fix: extract client disconnect logging helper to satisfy PLR0915

* fix: resolve mypy and code-quality CI failures for client disconnect logging

Cast client disconnect error_information for mypy, only await pending gather tasks to avoid masking LLM errors, and add tests for the new logging helper and gather cleanup.

* fix(proxy): harden gather cleanup so finally cannot mask LLM errors

* fix(proxy): shield streaming disconnect logging and strip spoofable metadata

Move streaming disconnect recording into a shielded cancel scope, add gather cleanup regression coverage for guardrail-converted cancels, and strip client_disconnected/error_information from user metadata at the proxy boundary.

* fix(proxy): only map CancelledError to 499 for client disconnect

Track when the disconnect poller cancels the LLM task and re-raise other CancelledError paths so graceful shutdown is not reported as HTTP 499.

* fix(proxy): remove dead _check_request_disconnection helper

Non-streaming client disconnect is handled by staging's cancel_on_disconnect path via _await_llm_call_cancelling_on_disconnect. Drop the unused is_disconnected poller and its unit tests; rename the remaining integration tests to TestDisconnectGatherCleanup.

* feat(mistral): add mistral-medium-3-5 to
  model_prices_and_context_window.json

Mistral's docs page lists mistral-medium-3-5 as a new model offering.

Pricing/specs sourced from Mistral's published model metadata:
- input: $1.50 / 1M tokens
- output: $7.50 / 1M tokens
- context: 262,144 tokens

Adds entry: `mistral/mistral-medium-3-5`, mirroring the pattern used for
the rest of the Mistral family.

test(mistral): add model_info test for mistral-medium-3-5 + sync backup
cost map
- Mirror mistral/mistral-medium-3-5 entries into
  litellm/model_prices_and_context_window_backup.json so the bundled
  model cost map matches the canonical
  model_prices_and_context_window.json.
- Add tests/test_litellm/test_mistral_medium_3_5_model_metadata.py
  covering pricing tiers, capability flags, context window, provider
  routing, and parity between the main and backup cost maps.
- Point 'source' at the live Mistral models documentation page.

* fix(ui): three small UI fixes — Gemini api_base + credential form reset + Mode badge (#30419)

* fix(ui): three small UI fixes — Gemini api_base field + credential form reset + Mode badge

Three independent fixes; bundled because they all touch the
credential-form / logging-callbacks area.

1. expose api_base field on Google AI Studio credential form
   The runtime gemini provider supports custom api_base via
   `vertex_llm_base._check_custom_proxy`; the UI just needs to expose
   the field. Adds api_base to the Google_AI_Studio credential form
   ordered before api_key (matching OpenAI/Anthropic conventions).
   Default value matches the canonical Google AI Studio endpoint that
   LiteLLM's gemini provider talks to when api_base is unset, so
   leaving the default in the form behaves identically to leaving it
   blank.

2. reset credential form state when switching providers
   Switching the Provider select in AddCredentialModal / EditCredentialModal
   left the previous provider's field values populated. The form then
   submitted a mixed payload (e.g. Azure deployment fields under an
   OpenAI credential), producing confusing failures.

   Extract `getProviderFieldDefaults` helper and reset the form to it
   on provider change. Unit-tested via the extracted helper because
   Antd Select's portal/dropdown behaviour is unreliable in jsdom.

3. logging callbacks table reads backend `type` for Mode badge (#35)
   The `/get_callbacks` proxy endpoint returns each callback as
   `{name, type, variables}` where `type` is `"success"` or
   `"failure"`. The same callback name can appear twice (one per event
   class) and the two entries fire on disjoint events.

   `LoggingCallbacksTable` ignored `type` and read `record.mode`
   (always undefined), so every row fell back to the "Success" badge.
   A `generic_api` callback registered for both classes showed up as
   two identical "Success" rows + React duplicate-key warning.

   Read `record.type` first (fall back to `record.mode` for newly-
   added not-yet-server-acknowledged rows). Composite rowKey
   `${name}-${type ?? mode ?? 'success'}`. Removed leftover debug
   `console.log`.

* fix(ui): drop api_base default_value to preserve Gemini v1alpha auto-routing

Greptile P2 (PR #30419, threads on lines 1255-1256 of
provider_create_fields.json): the api_base field's `default_value` was
hard-coded to "https://generativelanguage.googleapis.com/v1beta". This:

1. Bakes v1beta into every credential record saved through the form,
   even when the user never touched the field. If LiteLLM's internal
   gemini default URL ever changes, those persisted credentials keep
   hitting the stale path.

2. Bypasses `_get_gemini_url`'s automatic version routing for Gemini 3+
   models. That helper picks v1alpha for Gemini 3+ and v1beta for older
   models when api_base is unset. With the default pre-filled (and
   `_check_custom_proxy` then taking over because api_base is non-empty),
   Gemini 3+ requests get pinned to v1beta and may fail or behave
   unexpectedly — purely because the user accepted the visible default.

Fix: set `default_value` to `null` and move the canonical URL guidance
into the `placeholder` (visible to the user, never persisted) and an
expanded tooltip. UX is unchanged — the URL is still shown in the
greyed-out input — but the auto-version-routing path stays default.

Updated test_google_ai_studio_provider_fields_expose_api_base to assert
the new contract (`default_value is None`, `placeholder` carries the
canonical URL), with a comment pointing at the Greptile threads as the
rationale so future contributors don't accidentally re-introduce the
default.

26/26 tests in the file pass. JSON validates (`json.load` clean).

* feat(azure_ai): add gpt-5.5 to model cost map (#30428)

* feat(azure_ai): add gpt-5.5 to model cost map

Adds azure_ai/gpt-5.5 and its dated snapshot azure_ai/gpt-5.5-2026-04-23 to
both the canonical and bundled cost maps. gpt-5.5 is generally available on
Azure AI Foundry; pricing mirrors the openai gpt-5.5 entry, matching the
established azure_ai convention (verified identical for gpt-5.4), in the
azure tier structure (base / above-272k / priority). supports_minimal_
reasoning_effort is false, the capability that changed from gpt-5.4.

Fixes #30306

* fix(cost): apply service_tier suffix to above-threshold cache rates and expose priority+threshold keys in ModelInfo (#30450)

* fix(cost): apply service_tier suffix to above-threshold cache rates and expose priority+threshold keys in ModelInfo

Models that publish both a service_tier (e.g. priority) rate and an above-threshold tier (e.g. _above_200k_tokens) currently bill cached tokens at the standard above-threshold rate rather than the priority above-threshold rate. Affected entries in the live pricing JSON include gemini-3-pro-preview, gemini-3.1-pro-preview and their vertex_ai/ and gemini/ variants, plus azure/gpt-5.4 and azure_ai/gpt-5.4. For a 250K-token priority request with 200K cached tokens against gemini-3-pro-preview, the leak is about 44 percent of the prompt cost.

Two stacked defects caused this. First, ModelInfoBase (and the ModelInfo pydantic class) and the get_model_info construction in litellm/utils.py omit the priority+above-threshold cost keys, so even if the calculator asked for them they would never reach it. Second, in _get_token_base_cost the cache_creation/cache_read tiered keys never get wrapped with _get_service_tier_cost_key, while the input/output tiered keys above and below do. The change here surfaces six new keys (input, output and cache_read at both 200k and 272k priority variants) and wraps the three cache tiered keys in _get_token_base_cost the same way input/output already are. _get_cost_per_unit's existing service_tier-to-base fallback covers models that ship the standard above-threshold rate without a priority variant.

Adds one regression test in tests/test_litellm/litellm_core_utils/llm_cost_calc/test_llm_cost_calc_utils.py that drives the actual generic_cost_per_token path for gemini-3-pro-preview at 200K cached + 50K text under priority and asserts the priority above_200k rates are picked. Verified the test fails on litellm_internal_staging without these changes and passes with them.

* fix(cost): drop guard on cache tiered keys so service_tier fallback can reach standard above-threshold rate

Addresses Greptile P1 on PR 30450. The previous commit wrapped cache_creation_tiered_key, cache_creation_1hr_tiered_key, and cache_read_tiered_key with _get_service_tier_cost_key (matching how the sibling input and output tiered keys are wrapped) but kept the surrounding 'if key in model_info' guards. For models that publish a standard above-threshold cache rate but no priority variant (gpt-5.4-pro, gpt-5.5-pro and their dated siblings, plus vertex_ai/claude-sonnet-4-5 for cache_creation), the guard short-circuits before _get_cost_per_unit's existing service_tier-to-base fallback can strip _priority and find the standard above-threshold key. The result on priority requests over the threshold was that those models silently dropped from the above-threshold rate back to the priority-base rate. Dropping the guard and calling _get_cost_per_unit unconditionally (mirroring how tiered_input_key and tiered_output_key are already handled) restores correct billing for that class of models while keeping the new priority+above-threshold behaviour for gemini-3-pro-preview and friends.

Adds a second regression test that pins generic_cost_per_token for vertex_ai/claude-sonnet-4-5 priority + above_200k with cached and cache_creation tokens to the expected standard above-threshold rates, so the guard cannot be silently reintroduced for either the cache_read or cache_creation path.

* fix(presidio): skip pre-call masking when guardrail is logging_only (#30461)

The Presidio pre-call hook masked the live request unconditionally, ignoring
the configured event hook. With mode: logging_only the masked request reached
the model, so its response echoed anonymization tokens (e.g. <PERSON>) instead
of the real output. Gate async_pre_call_hook on should_run_guardrail, matching
every other guardrail; logging_only masking still happens via async_logging_hook.

* fix(router): resolve list unhashable crash on model alias (#30464)

* fix(router): resolve list unhashable crash on model alias

Fixes the fallback parsing logic that mistakenly categorized standard array fallback definitions as override dictionaries when a deployment alias matches the literal string 'model'.

Closes https://github.com/BerriAI/litellm/issues/30459

* fix(router): address greptile review for fallback parsing edge cases

- Resolves ambiguity in standard vs override fallback dictionaries by iterating over all items and validating that no mapped litellm param resolves to a non-list type.
- Adds regression tests in test_router_order_fallback.py to prevent unhashable type crash from silently re-entering the codebase.

* fix: remove timezone date expansion in daily-activity aggregation (#29569)

* fix: remove timezone date expansion in daily-activity aggregation

Single-day spend queries from non-UTC timezones over-counted by ~2x
because the previous implementation widened the SQL date range by a
full UTC day on whichever side the offset pointed. Spend is bucketed
in whole-UTC-day rows in LiteLLM_DailyUserSpend, so the expansion
pulled an extra 24h of unrelated bucket data per boundary.

Concretely on IST (UTC+5:30, offset -330): a single-day query for
2026-05-29 was rewritten to date >= 2026-05-28 AND date <= 2026-05-29
and returned spend across both UTC days. Sums of single-day queries
across a 5-day window then exceeded the equivalent multi-day aggregate
by ~50%, which is mathematically impossible.

Treat the local date range as the UTC date range. The aggregation
table has no hour-level granularity, so any conversion using only
date arithmetic must round to whole UTC days; the previous fix turned
that boundary slop into systematic over-counting. Pass-through trades
a small one-time slop at each end of the range for correct, monotonic,
additive results across single-day and multi-day queries.

Repro from production: bedrock/global.anthropic.claude-opus-4-8 over
2026-05-29 to 2026-06-02, IST timezone:
- 5-day aggregate: $701.39 / 1,831 reqs
- Sum of 5 single-day queries: $1,070.94 / 2,755 reqs
- Excess (was 1.527x): now matches within boundary slop

Adds regression tests in TestAdjustDatesForTimezone and
TestBuildAggregatedSqlQuery that pin the pass-through behavior and
the additivity invariant for any future implementation.

`_get_allowed_mcp_servers_from_mcp_server_names` returned the caller's full
allowed-server set when the requested `mcp_servers` list (path- or
header-derived) resolved to nothing. URL/header namespacing therefore
appeared to work even when the requested name was unknown or the caller had
no grant — `/mcp/<typo>/` silently exposed every server the key could reach.

Fail closed instead: when `mcp_servers` is explicitly provided but nothing
resolves, return an empty list. The `mcp_servers=None` path (no scope
requested) keeps its existing behavior.

* fix(token-counter): handle Anthropic tool_reference blocks to stop dropped spend logs (#30302)

* fix(token-counter): handle Anthropic tool_reference blocks to stop dropped spend logs

`token_counter` did not know about Anthropic tool-search `tool_reference`
content blocks, a lightweight pointer to a deferred tool that shows up as
`{"type": "tool_reference", "tool_name": ...}`. When such a block appeared in
message content, `_count_content_list` fell through to its catch-all branch and
raised `Invalid content item type: tool_reference`.

On the streaming `anthropic_messages` proxy path that exception nulls
`response_cost`, which makes the proxy drop the entire SpendLogs row. The result
is a silent cost undercount on any tool-search traffic; the request succeeds for
the caller but the spend is never recorded.

This adds a `tool_reference` branch that counts the referenced `tool_name` (the
full tool definition is already counted via the `tools` param, so only the name
is added here) and handles an empty/missing name gracefully. The catch-all error
message is updated to list `tool_reference` among the expected types.

A regression test asserts that a message containing a `tool_reference` block no
longer raises and returns a positive token count, and that an empty `tool_name`
is handled without error.

* fix(token-counter): collapse explicit None tool_name to empty string

In _count_content_list, c.get("tool_name", "") returns None when the
key is present with an explicit None value, and str(None) == "None"
which is truthy, causing a spurious token to be counted. Use
c.get("tool_name") or "" so both a missing key and an explicit None
collapse to an empty string and are skipped.

* test(token-counter): cover catch-all for unknown content block type

Adds a regression test that calls `_count_content_list` with an unrecognized
content block type and asserts it raises `ValueError` whose message names the
offending type and lists `tool_reference` among the supported types. This
exercises the previously uncovered catch-all branch (codecov patch gap) and
pins the error contract.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* test(token-counter): cover tool_reference on the spend/cost and streaming paths

Adds end-to-end regression tests that exercise the real public entry points
(`completion_cost` and `stream_chunk_builder`), not just the private
`_count_content_list` helper, for Anthropic tool-search `tool_reference`
content blocks.

These pin the actual bug the fix addresses: before the fix the `tool_reference`
block raised out of `completion_cost` -> the proxy logging layer nulled
`response_cost` and the spend callback dropped the SpendLogs row (silent cost
undercount on all tool-search traffic); and `stream_chunk_builder` swallowed the
same raise and collapsed prompt_tokens to 0. With the fix, cost is positive and
prompt_tokens are counted. Verified: 3 fail without the fix, 3 pass with it.

* feat(key/info): expose per-model budget usage in /key/info response (#30394)

* feat(key/info): expose per-model budget usage in /key/info response

Add model_max_budget_usage to /key/info and /v2/key/info responses.
For each model in model_max_budget, reads current-period spend from
the same DualCache used by the budget enforcer and returns it alongside
the limit and time period so callers can see how much of each model
budget has been consumed in the active window.

* test(key/info): add coverage for model_max_budget_usage in v1 and v2 endpoints

Add tests for the model_max_budget_usage enrichment in both info_key_fn
and info_key_fn_v2, covering the budget-present path, the empty-budget
path, and the v2 batch endpoint.

* fix(key/info): source model_max_budget current_spend from SpendLogs instead of DualCache

The DualCache used for enforcement is ephemeral and only populated when budget metadata
is present at request time. Fall back to a direct LiteLLM_SpendLogs DB aggregation
using the budget period window (budget_reset_at - budget_duration) for accurate reporting.
Also fall back to litellm_budget_table.model_max_budget when the key's top-level field
is empty, and round current_spend to 4 decimal places.

* test(key/info): cover remaining branches in model_max_budget_usage helpers

Add unit tests for: prisma_client=None early return, DB query exception swallowing,
invalid budget_duration handled by _compute_budget_period_start, budget_reset_at
received as a datetime object (Prisma native type), max_seconds=0 early return, and
skipping models that lack a budget_duration. Also remove an unreachable except branch
where fromisoformat would fail after _compute_budget_period_start already validated the
same value.

* test(key/info): cover except path for unparseable per-model budget_duration

* fix(key/info): compute per-model rolling windows in model_max_budget_usage

Each model in model_max_budget now gets its own time window derived from
its own budget_duration, rather than sharing a single window computed as
the max (or the budget table's reset_at). This matches what the DualCache
enforcer actually tracks and prevents current_spend from being inflated
for models with shorter windows.

_query_model_spend_for_period is refactored to accept a model filter
(handling provider-prefix variants in SQL) and return a float directly.
_compute_budget_period_start and the budget_table window path are removed
as they are no longer needed.

* refactor(model_max_budget_limiter): remove dead get_current_period_spend method

* refactor(key/info): strip synthetic formatter noise from PR diff

Restore key_management_endpoints.py and test_key_management_endpoints.py

additions: _query_model_spend_for_period, _build_model_max_budget_usage,
the two endpoint patches (info_key_fn / info_key_fn_v2), and the new
test suite. The previous commits had reformatted ~300 pre-existing lines
across both files, making the functional diff unreadable.

* test(key/info): cover empty-rows path in _query_model_spend_for_period

* fix(model_max_budget_limiter): guard BudgetConfig construction inside try/except

A malformed model entry in the DB (e.g. non-numeric max_budget from a
manually edited or migrated row) caused BudgetConfig(**budget_info) to
raise a Pydantic ValidationError outside any exception guard, surfacing
as a 500 for the entire /key/info or /v2/key/info call. Merging both
try/except blocks into one ensures bad entries are silently skipped,
consistent with the existing duration_in_seconds guard.

* fix: don't stack provider prefix on wildcard models with a custom prefix (#30360)

* fix: don't stack provider prefix on wildcard models with a custom prefix

get_known_models_from_wildcard expanded provider-prefixed model ids (e.g.
"ollama/gemma3:1b" from get_provider_models) by prepending the wildcard's
prefix whenever the id did not already start with it. With a custom wildcard
prefix such as "ollama_server1/*" (used to distinguish multiple Ollama
instances), this produced "ollama_server1/ollama/gemma3:1b", which is
uncallable and breaks /v1/models.

When the expanded id already carries a provider prefix, replace it with the
wildcard's prefix instead of stacking both. Matching-prefix and bare-model
cases are unchanged.

Fixes #30358

* fix: only strip a known provider prefix when expanding custom wildcard prefixes

The wildcard expansion replaced the leading slash segment of every expanded id with the wildcard prefix whenever the id did not already start with it. For ids whose first segment is an org rather than a litellm provider (for example a provider returning "meta-llama/Llama-3-8B" with no outer provider prefix), that dropped the org and produced an uncallable id

Only strip the leading segment when it is a recognized provider (membership in LlmProviders); otherwise keep it and just prepend the wildcard prefix. Provider-prefixed ids like "ollama/gemma3:1b" still have their prefix replaced, so the original fix is unchanged for known providers

* fix(proxy): raise litellm.BadRequestError for missing model param

When no model is passed, route_request now raises a litellm.BadRequestError

This keeps the missing-param error clear and independent of router wildcard
state. Unknown (non-empty) model names still raise ProxyModelNotFoundError.

* feat(aws-secret-manager): add replica_regions cross-region replication after CreateSecret

When store_virtual_keys is enabled, async_write_secret() only wrote secrets
to the primary AWS region. Multi-region proxy deployments had no built-in
way to synchronize virtual key secrets across regions through LiteLLM,
requiring external replication mechanisms.

Add replica_regions support to AWSSecretsManagerV2:
- New replica_regions field in KeyManagementSettings (types/secret_managers/main.py)
- New async_replicate_secret() method that calls ReplicateSecretToRegions API
- async_write_secret() calls replication after successful CreateSecret
- Replication failure is logged as a warning but does NOT fail key creation
- load_aws_secret_manager() forwards replica_regions from key_management_settings

Configuration example:
  key_management_settings:
    store_virtual_keys: true
    replica_regions:
      - us-west-2
      - eu-west-1

When replica_regions is omitted or empty, behavior is unchanged.

- Fix 2: add verbose_logger.info("ReplicateSecretToRegions called …") inside

  replication fires.
- Add test_replication_fires_on_create: calls async_replicate_secret directly
  with caplog.at_level(INFO, logger="LiteLLM") and asserts "ReplicateSecretToRegions"
  appears in the captured log output, proving the code path executes.

* fix(guardrails): run pre_call hook once for model-level guardrails (#30543)

* fix(guardrails): run pre_call hook once for model-level guardrails

A CustomGuardrail attached to a deployment via litellm_params.guardrails
gets its async_pre_call_hook invoked twice per request: once by the proxy
pre-call loop and again by async_pre_call_deployment_hook after the router
spreads the model-level guardrails into the top-level request kwargs.

Record in request metadata that the proxy pre-call loop already ran a given
guardrail, and have the deployment hook skip it when the marker is present.
Direct-SDK usage never runs the proxy loop, so the deployment hook stays the
sole invocation there and still fires exactly once.

The marker key is stripped from untrusted caller metadata so a request body
cannot suppress a model-only guardrail by pre-seeding it.

* fix(guardrails): mark pre_call dedup on the post-hook request data

Record the exactly-once marker after async_pre_call_hook runs, on the data
object that flows downstream, rather than before it. A guardrail whose hook
returns a brand-new request dict (instead of mutating or spreading the one it
received) would otherwise discard the marker, letting the deployment hook
re-run the guardrail a second time.

* fix(guardrails): stop re-initializing DB guardrails on every poll (#30542)

* fix(guardrails): stop re-initializing DB guardrails on every poll

InMemoryGuardrailHandler._has_guardrail_params_changed compared the
in-memory LitellmParams against the raw dict loaded from the DB. The
in-memory side carries every field default and coerces enums via
model_dump(), while the DB side only holds the keys originally stored,
so the two shapes never compared equal and the guardrail was rebuilt on
every poll cycle.

Each rebuild created a fresh instance, but delete_in_memory_guardrail
only removed the old callback from litellm.callbacks. Request handling
promotes guardrail callbacks into the success/failure/async lists, so
the previous instance stayed referenced there and instances accumulated.

Normalize both sides through LitellmParams(...).model_dump() before
diffing, and purge the callback from every callback list on delete.

* refactor(guardrails): narrow params-normalization fallback to ValidationError

The comparison normalizer caught a bare Exception and silently fell back
to the raw dict, which hid the cause and quietly degraded the affected
guardrail back to re-initializing on every poll. Catch only the
ValidationError that LitellmParams construction can raise, log a warning
so the offending row is diagnosable, and let any other error surface
instead of being swallowed.

* refactor(callbacks): add remove_callback_from_all_lists helper to manager

Move the knowledge of which callback lists a callback can be promoted
into out of the guardrail registry and into LoggingCallbackManager, where
the rest of the callback-list bookkeeping already lives. delete_in_memory_guardrail
now delegates to the new helper instead of iterating the lists itself.

* fix(router/proxy): propagate completed_response through FallbackResponsesStreamWrapper for streaming /v1/responses container ownership (#30210) (#30213)

* fix(router/proxy): propagate completed_response through FallbackResponsesStreamWrapper for streaming /v1/responses container ownership (#30210)

#28990 added ownership recording for streaming /v1/responses via
_wrap_responses_stream_for_container_ownership, which reads
`getattr(stream_response, 'completed_response', None)` to extract the
ResponsesAPIResponse. The unit test bypassed the Router, so it never
exercised the production wrapping path.

Through the Router (every proxy deployment), the stream is wrapped by
FallbackResponsesStreamWrapper (router.py:2527). Its __init__ set
`self.completed_response = None` and __anext__ only forwarded chunks
— the inner source iterator's terminal event never bubbled up to the
attribute the ownership hook reads, so the hook silently recorded
nothing and every follow-up /v1/containers/<id>/files call returned
403 for non-admin keys.

This commit:

- router.py: pre-resolves the responses-API terminal event tuple
  (response.completed / .incomplete / .failed) once per
  _aresponses_streaming_iterator call, and has the wrapper's __anext__
  sniff each forwarded chunk's .type. First terminal event hit gets
  stored on the wrapper's completed_response. Iterator-agnostic — works
  for source_iterator AND any future wrapper.

- common_request_processing.py: when _extract_completed_responses_response
  returns None we now warn instead of silently skipping. Reporter on
  #30210 lost a day to this exact silent skip; the warning surfaces
  future regressions of the same shape directly in operator logs.

Fixes #30210

* fix(router): type-ignore wrapper getattr-defaults; broaden ownership-skip warning

CI lint (mypy) flagged the three pre-existing getattr(..., None) assignments
in FallbackResponsesStreamWrapper.__init__:

  router.py:2564 self.response = getattr(source_iterator, 'response', None)
  router.py:2565 self.model    = getattr(source_iterator, 'model', None)
  router.py:2566 self.logging_obj = getattr(..., None)

Those lines also exist on litellm_internal_staging and pass mypy there.
Adding the typed terminal-event tuple above the class made the function
body more narrowable, which surfaced the pre-existing mismatch — base
class declares non-Optional types but the bridge path
(LiteLLMCompletionStreamingIterator) legitimately omits these. Keep
the None fallback and silence with type: ignore[assignment].

Greptile 4/5 note: the ownership-skip warning hard-named code_interpreter
which misleads operators when a non-code_interpreter stream aborts.
Generalize to 'any tool container (e.g. code_interpreter)'.

* fix(register_model): drop synthesized zero costs to preserve sparse entries (#30198) (#30201)

* fix(register_model): drop synthesized zero costs to preserve sparse entries (#30198)

get_model_info synthesizes input_cost_per_token / output_cost_per_token = 0
when they are absent from the raw entry (the price-unknown and free cases
share the same representation). register_model then merges that result back
into litellm.model_cost, which flips a sparse entry from 'no cost keys'
(priced via model name) to 'cost keys = 0' (free).

That defeats _is_cost_explicitly_configured (#24949) on re-registration:
_is_model_cost_zero returns True, common_checks skips every tag / key /
team / user / org budget check for the group, and over-budget traffic
keeps returning 200. Spend keeps recording because cost calc still resolves
by model name, so the symptom is silent and only triggers on the second
register_model pass (router rebuild, /model/update, config sync).

Mirror the existing litellm_provider-None guard one block above and pop
the cost fields from the synthesized result when they are absent from the
raw entry and not in the caller's value. Caller-provided zeros (genuinely
free models, BYOK overrides) are preserved.

Fixes #30198

* fix(register_model): switch _raw_entry to is-None checks + drop dead test assertion

Greptile #30201 review notes:
- the `or`-chain in the raw-entry lookup treated an empty dict (a key
  with no fields) as falsy and fell through to the second arm — replace
  with explicit `is None` checks so a present-but-empty entry is still
  taken at face value.
- the first assertion in `test_router_double_init_keeps_db_model_entry_sparse`
  used `in (None, 0)` which passes under the bug condition (cost = 0
  matches the tuple); the strong follow-up assertion already covers
  every shape, so drop the dead branch.

* fix(bedrock mantle): scope unique tool-call id fallback to degenerate call_id

The previous revision preferred the Responses item id for every tool call, which broke providers (and existing tests) where call_id is a unique, canonical correlation key. Restrict the fallback to the degenerate index-based call_id that Bedrock Mantle returns (call_0, call_1, ... resetting per response) and keep call_id otherwise. Revert the change to the OUTPUT_ITEM_DONE streaming handler, whose tool_call_chunk is never emitted (dead code, per review). Extend the regression tests to assert a normal call_id is preserved.

* fix(router): preserve azure_ad_token through CredentialLiteLLMParams for /v1/files + batches (#30235) (#30241)

* fix(router): preserve azure_ad_token through CredentialLiteLLMParams for /v1/files + batches (#30235)

Router.get_deployment_credentials_with_provider re-validates a
deployment's litellm_params through CredentialLiteLLMParams before
handing them to file/batch/passthrough callers:

    return CredentialLiteLLMParams(
        **deployment.litellm_params.model_dump(exclude_none=True)
    ).model_dump(exclude_none=True)

Any field NOT declared on CredentialLiteLLMParams gets silently dropped
on the way through. azure_ad_token was undeclared, so Azure deployments
using OAuth/M2M (azure_ad_token instead of a static api_key) silently
lost their token at the files endpoint and the proxy returned:

    Missing credentials. Please pass one of api_key, azure_ad_token,
    azure_ad_token_provider, ...

Declare azure_ad_token on CredentialLiteLLMParams alongside api_key /
api_base / api_version so it rides through the round-trip. Static-key
deployments stay unaffected (Optional, default None, dropped by
exclude_none=True). Provider-callable (azure_ad_token_provider) is a
separate concern and out of scope here.

Fixes #30235

* fix(ui-types): regenerate schema.d.ts for new azure_ad_token field

CI's 'Verify schema.d.ts matches the proxy OpenAPI spec' check
auto-detected the new field and emitted the exact diff to apply.
Two schemas had `aws_secret_access_key` from CredentialLiteLLMParams,
both get the new azure_ad_token marker next to it.

* fix(proxy): org_admin with own user_id now sees all org teams on /v2/team/list (#30247)

When the UI sends the callers own user_id (as it does for non-Admin
global roles), _enforce_list_team_v2_access now nulls it out for org
admins so _build_team_list_where_conditions scopes by organization_id
only -- matching the legacy /team/list behavior and the documented intent.

* test(vertex_ai): multi-region regression coverage for cachedContents host (#29571) (#29707)

litellm_internal_staging already routes the cachedContents URL through
get_vertex_base_url, fixing the multi-region 404 reported in #29571 —
but carries no test coverage for the actual regression scenario (eu/us
must resolve to the REP host aiplatform.{geo}.rep.googleapis.com).

Add TestContextCachingMultiRegionUrls: parametrized eu/us REP-host
assertions (including absence of the old broken {geo}-aiplatform host),
plus regional (us-central1) and global no-regression checks.

* fix(proxy): close upstream LLM stream when client disconnects mid-stream (#30245)

* fix(proxy): close upstream LLM stream when client disconnects mid-stream

When a streaming client disconnects, Starlette abandons the response
body iterator without calling aclose(), so the proxy's connection to
the upstream backend stays open until garbage collection, which may
never come. The backend (e.g. vLLM) keeps generating into a dead pipe:
small responses drain invisibly into TCP buffers while large ones block
the backend on a full send buffer indefinitely (observed via lsof as an
ESTABLISHED proxy->backend connection minutes after the client left)

create_response now returns a StreamingResponse subclass that closes
both its body iterator and the wrapped upstream-facing generator in a
shielded finally. The upstream generator is closed directly rather than
through a cascade because aclose() on a never-started generator skips
its body, which would make the cascade a no-op when the client
disconnects before the first chunk is sent.
async_streaming_data_generator also gains the same shielded
finally-aclose that async_data_generator in proxy_server.py already
had, covering the Anthropic and Google SSE paths

With this, killing a streaming client causes the backend to observe the
abort within about a second and free its slot, while completed streams
are unaffected. No flag is needed, unlike the non-streaming opt-in
cancel in #30223: this only releases resources after the client is
already gone and does not change any response a client can observe

Fixes #30244

* fix(proxy): close upstream even when body iterator aclose raises BaseException

Addresses the Greptile finding on #30245: the cleanup loop caught only
Exception while the generator-level cleanup catches BaseException, so a
CancelledError or GeneratorExit escaping body_iterator.aclose() would
skip closing the upstream generator. Both sites now use the same scope
and a regression test pins that the upstream is closed even when the
body iterator explodes with a BaseException

* fix(llms): expose aclose on BaseModelResponseIterator so stream close reaches the provider connection

The response-level close added for #30244 only worked for SDK-based
providers (e.g. openai), whose streams expose aclose all the way down.
Providers served by base_llm_http_handler (hosted_vllm and most modern
transformation-based providers) wrap a bare response.aiter_lines()
generator in BaseModelResponseIterator, which had no aclose or close at
all, and nothing retained the httpx response object; so
CustomStreamWrapper.aclose() silently did nothing and the upstream
connection stayed open. Verified with a vLLM-style mock: with
hosted_vllm/ the backend streamed all 100 chunks to completion after
the client disconnected, while openai/ aborted at chunk 6

BaseModelResponseIterator now carries an optional http_response and an
aclose() that closes it; make_async_call_stream_helper attaches the
response after building the iterator. With this, hosted_vllm aborts the
backend within ~1.6s of the client dropping, and completed streams are
unaffected

* fix(fallbacks): gate x-litellm-* passthrough to trusted callers only

The previous patch unconditionally let `x-litellm-*` keys bypass the
`llm_provider-` prefix in `process_response_headers`. That function is
also called on raw upstream-provider response headers (e.g. from
`llm_http_handler.py`), so a malicious provider could return
`x-litellm-attempted-fallbacks` and spoof a LiteLLM-internal marker,
bypassing the proxy model-override guard.

Add a `preserve_litellm_internal_headers` flag (default False). Only
`response_metadata.py`, which re-processes the already-built
`_hidden_params["additional_headers"]` dict (LiteLLM-owned), passes
True. Raw provider header callsites keep the default False, so upstream
`x-litellm-*` still gets the `llm_provider-` prefix.

Adds a regression test for the spoofing case and renames the existing
preserve test to make the trusted-path semantics explicit.

The overrides keep their full base-class signatures for MyPy compatibility, but those signatures carry more than five parameters, which tripped PLR0913 on each subclass redeclaration. Since the arity is dictated by the base class and cannot be reduced, decorate the overrides with typing_extensions.override; ruff treats that as the intended signal that the parameter count is not under the author's control and skips PLR0913. This restores the PLR0913 baseline to 1813.

* fix(lint): add @override to modelscope image generation overrides

Apply the same typing_extensions.override treatment to the image generation config so its inherited-signature overrides do not count against PLR0913.

* ci(lint): add blanket-noqa, dataclass-default, and unused-noqa Ruff rules (#30516)

* ci(lint): enforce blanket-noqa, dataclass-default, and unused-noqa rules

Enable PGH004 (blanket-noqa), RUF008 (mutable-dataclass-default),
RUF009 (function-call-in-dataclass-default-argument), and RUF100
(unused-noqa) in ruff.toml, and clean up every resulting violation.

RUF008/RUF009 were already clean. PGH004/RUF100 surfaced ~335 stale or
blanket noqas: blanket `# noqa` are now scoped to the rule they actually
suppress (mostly T201), dead directives are removed, and inapplicable
codes are trimmed (e.g. F401 dropped from `import *`).

lint.external lists rules enforced outside this config (the strict-rule
gate via ruff-strict.toml and upstream litellm's own ruff config) so
RUF100 keeps the noqa directives that protect them instead of stripping
coverage this config can't see.

* ci(lint): trim RUF100 external list to load-bearing codes only

Drop the 9 precautionary strict-gate codes (ANN001/002/003/401, B006,
PLR0913, PLW0603, RUF012, TID251) that have zero `# noqa` references in
the gated source. Keep only the 11 codes with live suppressions so
RUF100 doesn't flag them as unused. Future strict-gate suppressions can
re-add codes here (or fix the underlying issue) as needed.

* ci: ratchet lint and type-check gates (ruff preview, ANN, mypy, basedpyright) (#30379)

* ci: enable ruff preview rules under the budgeted strict gate

Turn on ruff preview in the strict-budget lane (ruff-strict.toml) only,
leaving the clean gate (ruff.toml) untouched so make lint-ruff stays at
zero. Enumerate the 118 firing codes explicitly with
explicit-preview-rules so the gate is deterministic and stable across
ruff upgrades rather than depending on preview auto-selecting the broad
catalog.

Grandfather the existing 58438 violations into ruff-strict-budget.json
as per-rule baselines with headroom, so only net-new violations fail CI.
The existing ten rules keep their hand-tuned slack; the new rules get
slack 10 when the baseline is 50 or more and 3 otherwise.

* ci: add ANN return-type rules to the budgeted strict gate

Add ANN201/202/204/205/206 (missing return annotations) to the strict
lane and grandfather the existing counts into ruff-strict-budget.json so
the codebase ratchets toward explicit return types without breaking CI.

* ci: add mypy (disallow_untyped_defs) and basedpyright strict gates with baselines

Add two type-check gates, each grandfathering the current tree so only
net-new violations fail CI, matching the ruff strict-budget ratchet.

mypy gains disallow_untyped_defs in litellm/mypy.ini (the config the CI
invocation actually reads; the root [tool.mypy] is not picked up from the
litellm/ working dir). The 4885 existing missing-annotation errors are
captured in litellm/.mypy-baseline.txt and the run is piped through
mypy-baseline filter so new untyped defs are rejected.

basedpyright runs in strict mode over litellm/, with
enableTypeIgnoreComments disabled so it only honors '# pyright: ignore'
and never polices mypy's '# type: ignore'. The existing strict diagnostics
are grandfathered into .basedpyright/baseline.json.

Both tools are pinned in the dev group and uv.lock; the lint workflow and
Makefile run them filtered through their baselines, with
lint-mypy-baseline-update and lint-basedpyright-baseline-update to ratchet.

* ci: raise lint job timeout to 15m for the basedpyright strict pass

* ci: pin pythonVersion 3.12 and regenerate baselines against merged base

Merge litellm_internal_staging so the baselines cover code the CI merge
includes (e.g. the cisco_ai_defense guardrail), which otherwise tripped
the mypy gate with 3 ungrandfathered no-untyped-def errors. Pin
pythonVersion 3.12 in pyrightconfig so basedpyright's strict analysis is
reproducible across interpreter versions (CI runs 3.12).

* ci: regenerate basedpyright baseline against the frozen lint env

The previous baseline was generated with optional provider deps (azure,
google, anthropic, mcp, numpydoc, google-genai) installed locally, so CI's
dev-only env surfaced ~3500 reportUnknown*/reportMissingTypeStubs errors
not in the baseline. Regenerate after uv sync --frozen so the baseline
reflects the same dependency set the lint job sees.

* ci: regenerate basedpyright baseline on python 3.12 frozen env

The prior baseline still carried proxy-dev packages (e.g. prisma) that the
lint job's dev-only, python 3.12 env lacks, leaving 2 unresolved-import
errors ungrandfathered. Regenerate in a python 3.12 venv synced to the
frozen lock with default groups only, so the baseline matches exactly what
CI sees.

* ci: replace type-check baselines with per-file count budgets

The mypy and basedpyright baselines were position-sensitive (and the
basedpyright one was a 27MB file), so ordinary line shifts churned them.
Replace both with a per-file count gate: scripts/type_check_gate.py reduces
each tool's output to errors-per-file and checks it against a committed
{file: max} budget, ignoring line and column numbers. A file fails only
when it gains more errors than its ceiling; debt can't be shuffled between
files because each file has its own cap and new files default to zero.

Budgets (mypy-file-budget.json 48K, basedpyright-file-budget.json 96K) are
generated in the python 3.12 frozen lint env so they match CI. Drops the
mypy-baseline dependency; basedpyright runs without its native baseline.
ratchet via make lint-mypy-budget-update / lint-basedpyright-budget-update.

* ci: add a small per-file slack to the type-check gate

Allow each file to drift PER_FILE_SLACK (5) errors past its recorded count
before failing, so a basedpyright inference ripple in an unrelated file
doesn't break the build over a couple of errors. Budgets still record exact
counts; the tolerance is applied at check time.

* ci: move type-check slack into the budget json and trim lint timeout

Make slack declarative: the budget is now {"slack": N, "files": {path: count}}
so the tolerance is tuned in JSON without editing the script, mirroring how
ruff-strict-budget.json carries its slack. --update preserves the existing
slack. Also drop the lint job timeout from 15m to 10m; the mypy and
basedpyright passes add ~2m, leaving the job around 4-5m, so 10m is a
comfortable margin.

* ci: collapse fully-adopted ruff categories and drop inert preview flag

ANN (all nine non-removed rules) and BLE (its only rule) were spelled out
code-by-code; replace each with its category selector, which is exactly
equivalent in 0.15.3 (the removed ANN101/ANN102 are skipped by a category
selector and error when named explicitly). explicit-preview-rules was inert:
every selected rule is stable and nothing is selected by category, so the flag
had nothing to gate. Verified the strict-rule counts are identical before and
after (62379 each, zero per-rule drift), so no budget change.

* ci: drop redundant pyright dev dependency

Nothing invokes bare pyright in the Makefile, the linting workflow, or
scripts; the basedpyright gate added on this branch is the only type
checker that runs. basedpyright is a superset fork that reads the same
pyrightconfig.json and honors the same "# pyright: ignore" comments, so
pyright==1.1.408 in the ci group was dead weight. Regenerated uv.lock
under the same exclude-newer cutoff so the only change is removing
pyright and its package stanza

* ci: un-weaken mypy and error on Any in basedpyright

mypy: enable warn_return_any, drop the valid-type silencer, and stop globally ignoring missing first-party imports via [mypy-litellm.*] ignore_missing_imports = False, which surfaced eight real broken litellm.* imports the blanket ignore was hiding; third-party imports stay ignored. The per-file budget moves 4888 -> 5799 (902 no-any-return, 1 valid-type, 8 import-not-found), all grandfathered so only net-new errors fail and the ceilings ratchet down

basedpyright: error on reportExplicitAny and reportAny. The per-file budget moves 117033 -> 148946 (6931 explicit-Any, 24954 Any-typed expressions), grandfathered the same way

* ci: add Any-discipline gate on changed lines under litellm/

Add scripts/check_any_discipline.py, a type-aware gate that fails when a
changed line holds a value typed Any -- including the X | Any unions that
mypy --strict / basedpyright accept (e.g. re.Match.group() -> str | Any,
json.loads() -> Any, bare dict -> dict[Any, Any]).

It reuses the repo's mypyc-compiled mypy 1.19 via a custom generic AST
walker (mypyc precludes subclassing TraverserVisitor), loads litellm/mypy.ini
for parity with lint-mypy, and uses a dedicated incremental cache
(.mypy_cache_any) with mtime+hash invalidation to force re-checks. Scope is
changed-lines-only so editing a legacy file never forces cleaning its
existing Any debt; suppress a genuine typed/untyped boundary with
# any-ok: <reason> (ANY002 requires the reason).

Wire it into the Makefile (lint-any, lint, lint-dev), a parallel
any-discipline CI job with its own actions/cache, .gitignore, and the
CLAUDE.md / CONTRIBUTING.md docs.

* ci: move Any-gate codes into the shared LIT namespace

Renumber the Any-discipline checker into the LIT*** scheme owned by
scripts/check_type_discipline.py (PR #30500) so the two checkers share one
rule namespace and suppression convention:

  ANY001 -> LIT002  (Any-typed value; LIT002 was the retired/free slot)
  ANY002 -> LIT005  (any-ok without a reason; the shared suppression-reason code)
  ANY000 -> LIT000  (setup/build/read error; the shared error code)

Messages and behavior are unchanged; LIT005's text already matches the
"<token> requires a reason" shape used for cast-ok/guard-ok.

* ci: gate mypy and basedpyright per error rule, not per file

Switch the mypy/basedpyright budget gate from per-file error counts to
per-rule-code totals, mirroring the {rule: {baseline, slack}} shape of
ruff-strict-budget.json. A rule fails when its codebase-wide error count
exceeds baseline + slack, so violations are tracked by category rather
than by file location.

scripts/type_check_gate.py now parses mypy from its text output (trailing
[code]) and basedpyright from --outputjson (the JSON `rule` field), since
basedpyright's wrapped text diagnostics mis-attribute the rule on
continuation lines. Replace the *-file-budget.json files with freshly
captured *-code-budget.json baselines and update the Makefile, CI, and
CLAUDE.md accordingly.

* docs: prefer Pydantic validation over any-ok suppression

Point the Any-discipline guidance at validating Any with Pydantic (a model
or TypeAdapter that returns a typed value or raises) and frame
# any-ok as a last resort that should ideally never be used.

* chore: remove extraneous comment

* chore: make the CLAUDE.md more concise

* chore: clean up bloated CONTRIBUTING.md additions

* chore: make Makefile more concise

* ci: add the lint-budget-update target CLAUDE.md references

CLAUDE.md tells contributors to run make lint-budget-update, but the
target was never defined. Add it as an aggregate that re-captures the
ruff, mypy, and basedpyright budgets in one shot.

* ci: recapture mypy and basedpyright budgets in the lint env

The per-rule baselines were captured in a richer dependency env than the
CI lint job's uv sync --frozen, so CI resolved fewer types and reported
more errors than the budgets allowed (no-any-return 902 over cap 900, plus
several basedpyright reportUnknown* rules). Regenerate both in the frozen
env so they grandfather the true CI debt: mypy 5786 -> 5799 (no-any-return
890 -> 902, valid-type 1 restored), basedpyright 146213 -> 148942.

* ci: check out PR head sha in lint and any-discipline jobs

The default pull_request checkout uses refs/pull/N/merge, which folds the
latest base commits into HEAD. The diff-based gates (ruff delta, Any
discipline) then diff against the event's older base.sha and blame base's
own new commits on this branch; staging's otel-v2 and streaming changes
(#30326, #30485) tripped the Any gate on files this branch never touched.
Checking out the PR head sha makes the gates diff the real branch tip
against base, and pins the tree the mypy/basedpyright budgets were captured
against so their counts stay deterministic as the base advances.

* ci(lint): renumber Any-typed-value rule LIT002 -> LIT009

Free up LIT002 for the sibling type-discipline gate (check_type_discipline.py,
#30500), which groups its mutable-collection family at LIT001 (annotation) and
LIT002 (construction). This gate's Any-typed-value rule moves to LIT009 so the
shared LIT namespace stays contiguous with no holes; LIT000 and LIT005 are
unchanged.

* style: rename lint-strict-budget -> lint-ruff-budget

* ci: harden type-check gates against silent passes (greptile review)

type_check_gate.py: refuse to certify a vacuous run. The CI pipe swallows
the tool's exit code ('tool || true'), so a crashed mypy/basedpyright that
emits nothing would parse to zero errors, breach no ceiling, and pass.
is_vacuous_run() now fails when nothing was parsed but the budget expects
errors. Also wrap basedpyright's json.loads in a JSONDecodeError handler
that prints the offending output instead of dumping a raw traceback.

check_any_discipline.py: ALL_LINES was None, which dict.get() also returns
for a path absent from the line map, so a path-normalisation mismatch could
let a violation on an unchanged file pass the scope filter. Make ALL_LINES a
distinct sentinel object so 'whole file' and 'path missing' are unambiguous.

Adds tests for all three.

* chore: satisfy strict-rule and any-discipline gates for the staging bundle

The strict-rule budget and any-discipline gates added in #30379 flag the
bundle's new lines: blind-except (BLE001), legacy typing imports
(UP006/UP035/UP045), and values typed Any on changed lines (LIT009).

Type-fix the cleanly-fixable cases (function signatures, payload dicts as
dict[str, object], BudgetConfig.model_validate over **kwargs, direct
KeyManagementSettings attribute access over getattr, Optional[X] -> X | None)
and suppress the irreducible untyped boundaries (request/streaming dicts,
cache reads, httpx responses, asyncio primitives, Pydantic model_dump
navigation) with # any-ok and a short reason.

Also fix two any-discipline gate false positives so legitimate code is no
longer flagged: the synthetic Any in Coroutine/Generator send and yield
protocol slots (the awaited/returned value is still checked), and the
special-form Any of a TypedDict field's TempNode rvalue placeholder.

* chore: extend basedpyright slack to the two rules #30563 left at default

PR #30563 raised basedpyright slack to ~10% of baseline across the noisy reportUnknown*/reportAny family so staging bundles clear the per-rule gate, but it left reportArgumentType (slack 3) and reportPrivateUsage (slack 10) at their original tight values. This bundle pushes those two 10 and 1 over their caps respectively, so apply the same ~10% policy: reportArgumentType baseline 1863 -> slack 180, reportPrivateUsage baseline 1625 -> slack 160. No baselines move; only the slack on these two rules

* fix: handle duplicate tool calls and stream tail disconnects

* fix(proxy): mark stream completed before tail yields, not after [DONE]

Clients routinely close the connection right after the final chunk or the
terminating data: [DONE] frame. Setting stream_completed only after those
trailing yields made the GeneratorExit from that close fall into the
disconnect branch, recording false 499 client_disconnected metadata for a
response that already delivered all content and fired success logging, and
double-releasing the max_parallel_requests slot the success callback had
already released. Restore stream_completed before the trailing raw-SSE,
error, and [DONE] yields so terminal-marker closes are treated as the
successful completions they are. The tool_use dedupe guard is kept.

fix(guardrails): stop re-initializing DB guardrails on every poll (#30542)
* fix(guardrails): stop re-initializing DB guardrails on every poll

InMemoryGuardrailHandler._has_guardrail_params_changed compared the
in-memory LitellmParams against the raw dict loaded from the DB. The
in-memory side carries every field default and coerces enums via
model_dump(), while the DB side only holds the keys originally stored,
so the two shapes never compared equal and the guardrail was rebuilt on
every poll cycle.

Each rebuild created a fresh instance, but delete_in_memory_guardrail
only removed the old callback from litellm.callbacks. Request handling
promotes guardrail callbacks into the success/failure/async lists, so
the previous instance stayed referenced there and instances accumulated.

Normalize both sides through LitellmParams(...).model_dump() before
diffing, and purge the callback from every callback list on delete.

* refactor(guardrails): narrow params-normalization fallback to ValidationError

The comparison normalizer caught a bare Exception and silently fell back
to the raw dict, which hid the cause and quietly degraded the affected
guardrail back to re-initializing on every poll. Catch only the
ValidationError that LitellmParams construction can raise, log a warning
so the offending row is diagnosable, and let any other error surface
instead of being swallowed.

* refactor(callbacks): add remove_callback_from_all_lists helper to manager

Move the knowledge of which callback lists a callback can be promoted
into out of the guardrail registry and into LoggingCallbackManager, where
the rest of the callback-list bookkeeping already lives. delete_in_memory_guardrail
now delegates to the new helper instead of iterating the lists itself.

fix(responses): presidio PII masking for Azure WebSocket and streaming (#30003)
* fix(responses): Presidio PII masking for Azure WebSocket and streaming

Wire Presidio into native Responses WebSocket forwarding and fix streaming output unmasking so masked tokens are restored for HTTP and WS clients.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Fix unused imports in responses handlers

* fix(responses): address Greptile review - Azure WebSocket model URL and PII logging

- Add model_in_websocket_url() to BaseResponsesAPIConfig (default True) so
  providers can opt out of ?model= being appended to WebSocket URLs.
- Override model_in_websocket_url() to return False for Azure, since Azure
  sends the model in the response.create body, not the URL query string.
- Use this flag in llm_http_handler to conditionally append ?model=.
- Pass masked message to _store_input() instead of the original PII-containing
  message so logging destinations do not receive unmasked PII.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(responses): mask nested response.create input format for Presidio PII

Handle the nested {"type":"response.create","response":{"input":[...]}}
format in _mask_response_create. Previously only the flat top-level input
was masked; the nested shape bypassed Presidio and forwarded raw PII
upstream. Now both shapes are normalized and masked before forwarding.

* style: apply black formatting to llm_http_handler and streaming_iterator

* style: suppress PLR0915 on async_responses_websocket

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(responses): add apply_to_output masking on Responses API WebSocket path

Previously the WebSocket guardrail filter excluded callbacks with
apply_to_output=True, leaving model-generated PII unmasked before
returning to the client.

- Collect apply_to_output callbacks separately in llm_http_handler and
  pass them to ResponsesWebSocketStreaming as output_guardrail_callbacks.
- Add _mask_response_completed method that calls check_pii(output_parse_pii=False)
  on text blocks in response.completed events, masking model output PII.
- backend_to_client now chains unmask (pii_tokens) → mask (apply_to_output)
  before forwarding each event to the client.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(responses): unmask PII tokens in streaming delta events and warn on guardrail init failure

- Rename _unmask_response_completed -> _unmask_response_event and extend
  it to also unmask response.output_text.delta (and other delta types)
  so real-time streaming clients receive original values, not PII tokens.
- Split the broad except-and-swallow into ImportError (expected in SDK-only
  environments) vs Exception (unexpected — now logs a warning so operators
  know masking is disabled).

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(responses): enforce authorized model on WebSocket frames and remove proxy import

Security: add _enforce_authorized_model to ResponsesWebSocketStreaming that
overwrites both flat and nested model fields in every response.create frame
with the connection-authorized model, preventing deployment-substitution
attacks where an authenticated user sends a different model name in the frame
body after connecting with an allowed model.

Layering: remove the _OPTIONAL_PresidioPIIMasking isinstance check and proxy
import from the SDK handler. Use duck-typed checks (callable check_pii +
get_presidio_settings_from_request_data) so any guardrail implementing the
interface works, not just Presidio.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(responses): add _unmask_pii_text to duck-typed contract and mask delta frames

- Add callable(_unmask_pii_text) check to the guardrail_callbacks filter so
  a custom guardrail missing that method cannot cause an AttributeError and
  silently kill the WebSocket session.
- Extend _mask_response_completed to also mask response.output_text.delta
  (and other delta types) for apply_to_output callbacks, so real-time
  streaming clients do not receive unredacted model-generated PII in deltas.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Fix Responses WebSocket guardrail edge cases

* fix(responses): log masked output and suppress deltas when apply_to_output active

- Move _store_event to after _mask_response_completed so logs receive the
  redacted form, not raw model output containing PII.
- Suppress delta event forwarding when output_guardrail_callbacks are
  present: per-fragment Presidio cannot catch PII that spans multiple
  chunks (e.g. "alice@" + "example.com"). Clients receive only the
  fully-masked response.completed, which Presidio scans on complete text.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(responses): mask and suppress response.output_item.done for apply_to_output

response.output_item.done carries completed item text in item.content[*].text
before response.completed arrives, allowing unmasked PII to reach the client.

- _unmask_response_event: unmask input-PII tokens in item.content[*].text
- _mask_response_completed: run check_pii on item.content[*].text for
  apply_to_output callbacks (same as response.completed handling)
- backend_to_client suppression: also skip response.output_item.done when
  output_guardrail_callbacks are active; client receives only the
  fully-masked response.completed

* Revert "fix(responses): mask and suppress response.output_item.done for apply_to_output"

This reverts commit 219fd54ea3446f4399fde40c07ba0617e2834573.

* fix(types): accept dict responses in guardrail output write-back

Streaming response.completed events pass a dict response object, so widen
_apply_guardrail_responses_to_output to match its existing runtime handling.

Co-authored-by: Cursor <cursoragent@cursor.com>

* perf(responses): skip Presidio masking on suppressed WebSocket delta events

Delta events are dropped wholesale when apply_to_output masking is active,
so masking them first issued a wasted check_pii call per fragment. Move the
suppression check ahead of the unmask/mask passes; the event type is
invariant across both, so client-visible behavior is unchanged.

* test(responses): cover Responses WebSocket PII masking hooks

Add regression tests for the native Responses WebSocket guardrail path:
input masking and model enforcement in _mask_response_create, token
unmasking in _unmask_response_event, apply_to_output masking and delta
suppression in _mask_response_completed/backend_to_client, and the
get_websocket_url / model_in_websocket_url defaults for the base and
Azure configs. Raises diff coverage above the codecov patch target.

* fix(responses): suppress text-bearing done events under output PII masking

When apply_to_output masking is active on a native Responses WebSocket,
response.output_text.done, response.content_part.done, and
response.output_item.done carry the full model output before the masked
response.completed arrives, so an authenticated client could read
unmasked PII from those events. Suppress them alongside delta events; the
client receives only the fully-masked response.completed.

* refactor(responses): drop dead delta branch in WebSocket output masking

Delta events are suppressed in backend_to_client before _mask_response_completed
runs when output masking is active, so the method's delta-handling branch was
unreachable. Restrict it to response.completed and cover the Responses API
unmask path with a Pydantic ResponseCompletedEvent regression test.

* fix(presidio): flush buffered chat chunks on mixed unmask stream

_stream_pii_unmasking buffered ModelResponseStream chunks but returned
early once a /v1/responses event was seen, silently dropping the buffered
chat chunks. Flush them in order before switching to passthrough, mirroring
_stream_apply_output_masking, and cover it with a regression test.

* fix(responses): mask instructions and tool-call arguments in WebSocket PII path

Presidio masking on the native Responses WebSocket path left two gaps. On the
request side _mask_response_create only walked the input containers, so PII
placed in the instructions field of a response.create frame was forwarded
upstream and logged unmasked even with output_parse_pii enabled. Now both the
flat and nested instructions strings are masked alongside input.

On the response side _mask_response_completed only masked content text blocks,
so model-produced PII inside function-call arguments could reach the client when
apply_to_output was enabled, both via the standalone
response.function_call_arguments.done event and via the function_call output
items in response.completed. The done event is now suppressed under output
masking and completed function-call arguments are run through check_pii before
forwarding or logging.

* fix(responses): suppress reasoning_summary_text.done under output PII masking

* fix(responses): mask function_call_output.output in WebSocket PII path

response.create input items of type function_call_output carry
user-controlled text in output, not content, so the Presidio masking
pass forwarded that text upstream unmasked. Mask the output field
(string or list of text blocks) alongside content.

* fix(responses): mask reasoning summary PII in WebSocket output path

feat(proxy): enforce key/team guardrails on bedrock passthrough routes (#30194)
* feat(proxy): enforce key/team guardrails on bedrock passthrough routes

/bedrock/... passthrough routes silently skipped all guardrail hooks because
CallTypes.allm_passthrough_route had no entry in guardrail_translation_mappings.
Add a dispatcher (LlmPassthroughRouteHandler) registered for that call type that
routes to BedrockPassthroughGuardrailHandler for Bedrock Converse endpoints; wire
post_call_success_hook into both the JSON and AWS event-stream response paths in
common_request_processing, including full de-anonymization for streaming responses
with proportional text distribution across original event-stream delta frames.

* refactor(proxy): address greptile feedback on bedrock passthrough guardrails

Move botocore event-stream logic from proxy/ to BedrockPassthroughGuardrailHandler.de_anonymize_converse_stream; _handle_event_stream_allm_passthrough_route becomes a thin provider dispatcher. Pass custom_headers through _handle_non_streaming_allm_passthrough_route so early-return guardrail responses include x-litellm-call-id and related headers.

* style: run black on handler and common_request_processing

* refactor(proxy): dedupe non-streaming passthrough guardrail handling

Replace the inline JSON/eventstream block in the streaming-request branch
with a call to _handle_non_streaming_allm_passthrough_route so both paths
share one implementation and cannot diverge.

* fix(bedrock): preserve trailing bytes when re-encoding converse stream

The event-stream re-encoder only emitted parsed frames, so any trailing
bytes left after the parse loop (truncated/corrupt final frame, or fewer
than 16 bytes after the last complete frame) were silently dropped from
the de-anonymized output. Capture and re-append them so the transformer
never truncates the stream.

* fix(proxy): guard non-dict post-call hook return on bedrock passthrough JSON path

* fix(proxy): guard malformed JSON body on bedrock passthrough guardrail path

* fix(proxy): close guardrail bypass via tool result text and default-mode post-call guardrails on bedrock passthrough

Pre-call extraction only read top-level Converse text blocks, so blocked
content placed under toolResult.content[].text was forwarded to Bedrock
without the key/team guardrail seeing it. Extraction now walks nested tool
result text and write-back mutates the owning block in place.

Post-call buffering for passthrough used _has_post_call_guardrails, which
excludes event_hook=None guardrails. Those guardrails run at post_call, so
their output processing was skipped and the raw upstream body was returned.
Add a passthrough-specific predicate that counts them.

* refactor(proxy): route bedrock event-stream de-anonymization through llm passthrough dispatcher

Remove the hardcoded bedrock provider guard from common_request_processing
by delegating event-stream de-anonymization to LlmPassthroughRouteHandler,
which resolves the provider from the existing handler registry. Keeps
proxy/ provider-agnostic and reuses the same dispatch path as the input
and output guardrail handlers.

Also log instead of silently dropping the result when post_call_success_hook
returns a non-dict on the JSON and event-stream passthrough paths.

* fix(proxy): close guardrail bypass on bedrock invoke passthrough routes

Pre-call extraction and post-call output processing only handled Converse
shapes, so /bedrock/model/{modelId}/invoke and invoke-with-response-stream
returned unguarded. An authenticated caller could move blocked content into
an InvokeModel payload and skip the key/team guardrail entirely.

Non-Converse Bedrock routes now fall back to the generic passthrough handler,
which scans the full request and response payloads so blocking guardrails
still run, matching how other passthrough providers are guarded.

* fix(proxy): keep non-bedrock passthrough streams streaming under post-call guardrails

* fix(bedrock): scan non-text converse blocks for passthrough guardrails

Key/team guardrails on bedrock converse passthrough only saw top-level
text blocks, so a caller could hide prompt content in toolUse.input or
toolResult.content[].json and have it forwarded to Bedrock without the
configured guardrail inspecting it, bypassing blocking guardrails by
default. Walk those arbitrary-JSON subtrees and write masked values back
in place. Extend the non-streaming converse response path to the
equivalent model-output fields (toolUse.input, reasoningContent text and
citationsContent text) while leaving structural values such as reasoning
signatures and citation sources untouched.

* fix(bedrock): make passthrough guardrail string collection iterative and type-safe

Rewrite _collect_strings with an explicit stack so it no longer recurses,
satisfying the recursive-function CI guard, and widen the holder container
type so mypy accepts indexing JSON nodes by str or int keys.

* fix(proxy): scope passthrough post-call guardrail buffering to the request

Buffering the Bedrock event stream into a single non-streaming response was
gated on whether any post_call guardrail existed globally, so every
converse-stream request lost streaming once any post_call guardrail was
registered, even for keys that did not reference it. Mirror the gate used by
post_call_success_hook (should_run_guardrail against the request's merged
guardrails) so only requests whose key/team actually trigger a post_call
guardrail are buffered.

* fix(bedrock): guardrail non-text converse stream deltas on passthrough

de_anonymize_event_stream only routed delta.text through the post-call guardrail, so model output streamed in reasoningContent.text, toolUse.input or citationsContent.content[].text was forwarded raw and skipped masking/blocking. Collect every user-visible text field per contentBlockDelta, concatenate per logical stream so split mask tokens still reassemble, run them through the hook, then redistribute the guardrailed text back into the matching delta fields. This brings streaming coverage in line with the non-streaming Converse output handler.

* refactor(proxy): keep bedrock event-stream content-type detection in llms

Move the vnd.amazon.eventstream content-type check out of the proxy
passthrough path into BedrockPassthroughGuardrailHandler via the
LlmPassthroughRouteHandler dispatcher, so proxy code stays
provider-agnostic. Also patch the actually-called
_has_post_call_guardrails_for_passthrough in the malformed-body
regression test instead of the unused _has_post_call_guardrails.

* fix(proxy): forward upstream headers on bedrock guardrail passthrough responses

Mirror the non-guardrail passthrough path by merging the upstream
response headers (via get_response_headers) into the guardrailed
non-streaming and event-stream responses, so headers like
x-amzn-requestid survive when a post-call guardrail rewrites the body.
Drop the stray fastapi HTTPException import from the SDK-tree handler
test in favor of a local sentinel exception.

* fix(bedrock): scan tool definitions and additional request fields for passthrough guardrails

Converse passthrough guardrails only scanned system and message content, so
a key holder could route blocked or PII text through toolConfig tool names,
descriptions and input schemas or through additionalModelRequestFields, all
of which are still forwarded to Bedrock. Collect strings from those fields
too so key/team guardrails inspect and rewrite them, matching how the
chat-completions path forwards tool definitions to guardrails.

* fix(bedrock): log instead of silently dropping passthrough guardrail edge cases

* test(local): skip httpbin timeout probe when the service returns 5xx

local_testing_part1 was failing on test_post_delay_exceeds_per_request_timeout_raises
because httpbin.org/delay/10 intermittently answers 503 instead of delaying, so
HTTPHandler.post raised MaskedHTTPStatusError rather than the expected Timeout. The
test already means to skip when httpbin is unavailable, but its guard only probed
GET /get and ignored a server error on the delay endpoint. Treat a 5xx from httpbin as
'service unavailable' and skip, which is outside this repo's control, while still
asserting Timeout when httpbin genuinely delays.

* fix(proxy): set content-type on buffered bedrock passthrough event-stream responses

* fix(bedrock): skip passthrough output write-back when guardrail returns no texts

* fix(proxy): apply response-headers hook on guardrailed bedrock passthrough responses

* refactor(bedrock): import event-stream crc32 from binascii not botocore internals

* fix(proxy): scope bedrock passthrough stream buffering to de-anonymizable endpoints

Only buffer a passthrough event stream into a non-streaming response when the
resolved provider and endpoint actually have an event-stream guardrail handler
that can rewrite frames (Bedrock converse-stream). Other Bedrock event-stream
endpoints such as invoke-with-response-stream keep streaming, since the Converse
handler leaves their frames untouched and buffering would silently break the
streaming contract for no content change.

* test(ui-e2e): re-issue deep-link navigation when auth bootstrap drops the page param

navigateToPage deep-links to /ui?page=<page> then proceeds once the network
settles, but a fresh load can race the auth bootstrap: the app momentarily
treats the session as anonymous, bounces through /ui/login, and returns to the
default Virtual Keys page with the ?page= query param dropped. The helper never
checked where it actually landed, so any single bounce left callers asserting
against the wrong page and timing out (mcpServers, modelHub, addModel).

Confirm the requested page is what rendered and re-issue the navigation when it
was clobbered; auth is warm by the second load so the param sticks. Migrated
path routes are left alone since they intentionally leave the legacy root.

feat: litellm oss 110626 (#30202)
* Add gpt-realtime-whisper Realtime transcription support (OpenAI + Azure) (#29775)

* Add gpt-realtime-whisper Realtime transcription support (OpenAI + Azure)

Adds first-class support for the gpt-realtime-whisper streaming speech-to-text
model, which uses the Realtime transcription session API rather than the
file-based /audio/transcriptions path.

Model registration: registers gpt-realtime-whisper and azure/gpt-realtime-whisper
with audio-duration pricing (input_cost_per_second = 0.017/60, matching the
published $0.017/minute input audio rate).

REST endpoint: implements POST /v1/realtime/transcription_sessions (plus /realtime
and /openai/v1 aliases) to mint an ephemeral transcription session for the
WebRTC flow. Adds request/response types, OpenAI and Azure URL builders, a shared
base handler (refactored from the client_secrets handler), the
acreate_realtime_transcription_session SDK function, and route registration. The
proxy encrypts the ephemeral key returned under client_secret.value and records
the session type in the token so the follow-up /realtime/calls replays
type=transcription rather than type=realtime.

WebSocket: forwards intent=transcription through to the Azure handler (OpenAI
already received it) with URL-encoding, so gpt-realtime-whisper opens a
transcription session. Transcription-only sessions no longer trigger an
erroneous response.create.

Cost tracking: transcription sessions emit no response.done events; their usage
arrives on conversation.item.input_audio_transcription.completed as
{type: duration, seconds}. That usage is captured out-of-band (usage only, no
transcript duplication) and billed by input_cost_per_second, with a token-billed
fallback for token-priced transcription models.

Adds tests for pricing math, URL builders, request/response types, the proxy
route and SDK function, WebSocket intent forwarding, transcription-session
streaming behavior, and the /realtime/calls session-type replay.

* Address PR review: URL-encode all Azure WS query params; forward query_params through provider_config branch

* Address PR review: session_type validation, model auth fix, cost perf, billing fallback, detail/docs cleanup

* Improve test coverage: detection from backend, error paths, unknown usage type, resolved_model None

* Backport realtime transcription websocket fixes

* Enforce authorized realtime transcription model

* Enforce realtime transcription model access

* Enforce realtime resolved model scopes

* Enforce WebRTC transcription model scope

* Lazy evaluate debug log in pass-through endpoint (#30177)

* Pass through debug lazy logging

* fix(proxy): convert remaining eager pass-through debug logs to lazy formatting

* fix(parallel_ai): migrate search integration from v1beta to v1 endpoint (#30157)

* fix(parallel_ai): migrate search integration from v1beta to v1 endpoint

The Parallel Search API moved from /v1beta/search (processor: base/pro,
parallel-beta header) to /v1/search (mode: turbo/basic/advanced, no beta
header). Request fields moved too: max_results, source_policy, and excerpt
settings are now nested under advanced_settings, and source_policy uses
include_domains/exclude_domains. The v1 response returns publish_date per
result, which now maps to SearchResult.date instead of being hardcoded to
None. The legacy processor param is mapped to the equivalent mode so
existing callers keep working.

* fix(parallel_ai): default mode to basic and simplify param handling

The v1 API defaults to advanced mode when mode is omitted, while v1beta
defaulted to the base processor. Without an explicit default, callers who
pass no mode would be silently upgraded to a tier costing 2.25x more while
litellm's cost map reports the basic-tier price. Sending mode=basic
preserves the v1beta default and keeps cost tracking accurate.

Also replaces the handled_params set with pop-as-consumed param handling so
mapped params no longer need to be tracked in two places, and extends the
tests to pin the default mode, processor=base mapping, mode-over-processor
precedence, and top-level v1 param passthrough.

* fix(parallel_ai): avoid double /v1 when api_base is already versioned

A PARALLEL_AI_API_BASE like https://api.parallel.ai/v1 previously produced
.../v1/v1/search. Strip a trailing /v1 before appending the search path and
cover the api_base variants with a parametrized test.

* feat(focus): add Mavvrik destination for FOCUS export (#29935)

* fix: preserve responses streaming flag (#30189)

* fix: preserve responses streaming flag

* test: cover async responses streaming flag

* fix(spend/daily-activity): stable offset pagination via id tiebreaker (#30164) (#30167)

date alone is not a unique sort key for LiteLLM_DailyUserSpend or
LiteLLM_DailyTeamSpend (many rows per date: api_key x model x
model_group x provider x endpoint). Offset pagination over a
non-unique sort landed on arbitrary boundaries, so a client paging
through all results and summing per-page metrics (the Usage dashboard)
got non-deterministic totals - sometimes inflated, sometimes deflated,
different at different page_size values.

Adding the row's UUID id (present on both tables) as a secondary sort
gives every page a stable cursor. order=[{date desc}, {id asc}].

Fixes #30164

* fix(oci): inject a default maxTokens so omitted max_tokens doesn't truncate responses (#30018)

* fix(oci): inject default maxTokens so omitted max_tokens doesn't truncate

OCI GenAI applies a tiny server-side maxTokens default (~20 tokens) when the
request omits it, so any call that doesn't send max_tokens comes back cut off
mid-string with finishReason "length". MLflow judges never send max_tokens, so
their JSON responses arrived as unterminated strings and json.loads failed in
MLflow's gateway adapter.

When no maxTokens/maxCompletionTokens target is set, inject
DEFAULT_OCI_CHAT_MAX_TOKENS (env-overridable, defaults 4096), mirroring the
Anthropic config's default-max-tokens behaviour. An explicit max_tokens still
wins, and reasoning models still route to maxCompletionTokens. Used a fixed
default rather than the catalog max_output_tokens because the catalog value is
unreliable for some models (grok-4 reports max_output_tokens equal to its
context window, not a real output cap, which would risk 400s).

Adds TestOCIDefaultMaxTokens covering Cohere and generic injection, the
explicit-override case, and the reasoning maxCompletionTokens branch.

* test(oci): e2e regression that omitted max_tokens isn't truncated

Real-proxy integration test asserting a chat completion that omits max_tokens
completes with finish_reason "stop" instead of being cut off at OCI's ~20-token
server default. Fails before the maxTokens-default injection (finish_reason
"length", ~19 tokens), passes after.

* test(oci): update cohere default-params test for injected maxTokens

test_cohere_default_parameters asserted no maxTokens was injected, encoding the
old behaviour where OCI's ~20-token server default truncated responses. Now
that transform_request injects DEFAULT_OCI_CHAT_MAX_TOKENS, assert maxTokens
equals that default while the other params (topK/topP/frequencyPenalty) stay
pass-through with no hardcoded default.

* fix(oci): make DEFAULT_OCI_CHAT_MAX_TOKENS a plain constant

Drop the os.getenv override. The env knob was not requested and introducing a
new env var forced a cross-repo dependency on litellm-docs (test_env_keys.py
validates every referenced env var against the docs table there). A plain 4096
constant keeps the PR self-contained; callers who want a different limit pass
max_tokens explicitly per request.

* fix(oci): route all OpenAI commercial models to maxCompletionTokens

OCI serves OpenAI models (gpt-4.1, gpt-5.1 through 5.5, o-series) that
the litellm catalog doesn't track, so the supports_reasoning lookup
returned False for them and the provider sent maxTokens, which the
reasoning families reject with HTTP 400. With the injected default
maxTokens this broke every request to those models, not just ones with
an explicit max_tokens. Route the whole openai.* vendor prefix to
maxCompletionTokens since OpenAI accepts max_completion_tokens on every
chat model; the openai.gpt-oss-* open weights are served by OCI's own
stack and keep maxTokens. Verified live against gpt-5.2, gpt-5, gpt-4o,
gpt-4.1, gpt-oss-120b, llama-3.3, command-a and grok-3-mini

* test(oci): hoist transformation imports and drop unused ones

Makes the generic-chat test file ruff-clean: the per-test local imports
of OCIChatConfig/OCIVendors shadowed the module-level import (F811) and
left it unused (F401), and json plus three OCI type imports were never
referenced

* fix(oci): translate response_format json_schema to OCI's accepted shape (#29691)

* fix(oci): translate response_format json_schema to OCI's accepted shape

OCI GenAI rejected every json_schema response_format with HTTP 400
"Please pass in correct format of request", which broke structured-output
callers such as MLflow LLM judges (they always send a json_schema).

The provider forwarded OpenAI's raw json_schema body unchanged. For GENERIC
models OCI's ResponseJsonSchema accepts only name/description/schema/isStrict,
so OpenAI's `strict` key (and any other extra) 400s the request; the key must
be renamed to isStrict and the body whitelisted. For Cohere models there is no
JSON_SCHEMA type at all; the schema has to ride on JSON_OBJECT as
{"type": "JSON_OBJECT", "schema": ...}. Cohere type values must also be the
canonical uppercase TEXT/JSON_OBJECT.

_normalize_response_format now branches by vendor and emits the exact shape
each one accepts (verified live against OCI GenAI for Cohere, Meta, Gemini and
Grok). Drops the unused, incorrect Cohere response-format pydantic models.

Two existing tests asserted the broken behavior (lowercase type, raw
jsonSchema on Cohere); they are rewritten to assert the corrected shape, and
generic/Cohere json_schema regression tests are added.

* fix(oci): raise early on json_schema response_format with no body

A GENERIC model request with {"type": "json_schema"} and no json_schema
object fell through to the JSON_OBJECT branch and emitted a bodyless
{"type": "JSON_SCHEMA"}, which OCI rejects with an opaque HTTP 400. Raise a
descriptive 400 at translation time instead. Cohere is unaffected since it
always maps to JSON_OBJECT.

* test(oci): gateway integration test for response_format json_schema

Added to tests/integration/ (the real-network integration suite) reusing the
existing OCI proxy harness, not tests/llm_translation/ which is mock-only.

* fix(oci): accept default n=1 on Cohere instead of hard-failing (#29705)

* fix(oci): accept default n=1 on Cohere instead of hard-failing

Cohere on OCI has no numGenerations field, so n was mapped to False and
map_openai_params raised "param `n` is not supported on OCI" whenever a client
sent n. But n=1 (and None) is the OpenAI default single-generation request,
which every OCI model produces anyway, so standard clients that always send
n=1 (such as the MLflow gateway) were rejected with a 500.

Drop n=1/None silently for Cohere; only n>1 is genuinely unsupported and still
raises (or drops under drop_params). Generic models are unaffected and keep
numGenerations, including n>1.

* docs(oci): explain why n is not advertised for Cohere despite tolerating n=1

* test(oci): gateway integration test for Cohere default n=1

Added to tests/integration/ (the real-network integration suite) reusing the
existing OCI proxy harness, not tests/llm_translation/ which is mock-only.

* fix(oci): drop max_retries instead of hard-failing on OCI (#29727)

max_retries is a litellm-level control param (litellm applies retries itself),
not a generation param OCI accepts. The provider mapped it to False and raised
"param `max_retries` is not supported on OCI" whenever it was present. The
litellm proxy injects max_retries on every request, so any OCI call through the
proxy 500'd unless drop_params was set.

Drop max_retries silently in map_openai_params. Adds a unit test (Cohere and
generic) and a gateway integration test that a plain request succeeds through a
proxy without drop_params.

* fix(spend-logs): rehydrate metadata JSONB text on ui_view_spend_logs (#29682)

Fixes #29674.

`/spend/logs/ui` raw-SQL path returns the JSONB metadata column as a
string — prisma's query_raw skips the ORM-layer hydration. The UI reads
metadata.status / metadata.error_information as object fields, so
provider-failure rows look like successes.

Fix: json.loads the metadata field right after query_raw, fall back to
{} on malformed JSON.

3 existing error-code/error-message tests called json.loads on
response.data[0]["metadata"] — they were leaning on the bug. Updated
to read the dict directly. Plus 2 new regression tests (failure metadata
roundtrip + invalid-json fallback). Reverting the fix makes both new
tests fail with AssertionError: metadata should be dict, got <class 'str'>.

* fix(proxy): release max_parallel_requests slot when a stream is cancelled mid-flight (#27955) (#30020)

* fix(proxy): release max_parallel_requests slot when a stream is cancelled mid-flight (#27955)

* fix: refund max_parallel_requests on disconnect from outer streaming generators

The cancellation refund previously lived in async_post_call_streaming_iterator_hook,
but that hook is nested inside the outer streaming generators and a nested async
generator only receives GeneratorExit on garbage collection (non-deterministic).
With only the v3 limiter enabled, /chat/completions also bypasses the hook entirely
(needs_iterator_wrap() is false). Move the release into async_data_generator and
async_streaming_data_generator, the generators Starlette closes on client disconnect,
so the refund fires deterministically on every streaming route. Warn when no event
loop is running, and document the window TTL refresh on the decrement

* fix(mcp): propagate model into model_call_details for passthrough tool calls (#30122)

* fix(mcp): propagate model into model_call_details for passthrough tool calls

The @client decorator on call_mcp_tool creates the logging object via
function_setup without a model kwarg, so model_call_details["model"]
starts as None. execute_mcp_tool only set logging_obj.model as an
instance attribute, which the spend-log writer never reads (it reads
kwargs["model"] from model_call_details). MCP passthrough tools/call
rows therefore persisted with model="" while list_tools rows showed
"MCP: list_tools", degrading the Logs UI display and bucketing all MCP
tool spend under an empty model in DailyUserSpend.

Propagate the model into model_call_details alongside the existing
attribute assignment so the StandardLoggingPayload and SpendLogs writer
pick it up. Covers the /mcp passthrough, REST /mcp-rest/tools/call, and
orchestrated paths (the latter already passed model into function_setup,
so this is a no-op there).

* fix(gemini): don't emit empty choices on metadata-only stream chunks (#29167)

web_search + reasoning makes Gemini stream mid-chunks that carry only
grounding/thought metadata — no content part, no finishReason.
_process_candidates skips content-less candidates and the existing
fallback only ran when finishReason was set, so choices stayed empty
and the downstream streaming handler raised IndexError on choices[0].
Emit an empty-delta choice for content-less chunks regardless of
finishReason.

Fixes #28884

* fix(key): allow /key/update to clear budget_limits with [] or null (#30085)

* Fix /key/update rejecting budget_limits clear requests with HTTP 400

Sending budget_limits: [] or null to /key/update returned HTTP 400, so
once a key had budget windows the last one could never be removed.

prepare_key_update_data only json.dumps'd budget_limits when the value
was truthy, so [] and None passed through raw to the Prisma Json?
column; jsonify_object only serializes dicts, and prisma-client-py has
no DbNull sentinel for Json? writes, so Prisma rejected both shapes.

Serialize the clear case explicitly as the JSON literal null, matching
how memory_endpoints encodes metadata for the same column type. Truthy
values keep the existing reset_at window initialization path.

Fixes #30067.

* Require admin access for budget_limits changes on /key/update

Clearing budget_limits via [] or null is a budget mutation, but
_validate_update_key_data only counted max_budget and spend as budget
changes before deciding whether to skip _check_key_admin_access. A
non-admin key owner or a team member with /key/update could therefore
remove a key's per-window spend caps without admin authorization.

Treat any explicit budget_limits value in the request (set, change, or
clear) as a budget change so it gates through the same admin check as
max_budget. model_fields_set is used because an explicit null is
indistinguishable from an omitted field by value alone.

* fix(proxy): persist guardrail info in spend logs for /v1/responses (#30092)

Pre-call guardrail blocks on /v1/responses wrote guardrail_information
as null in LiteLLM_SpendLogs because _handle_logging_proxy_only_error
splits request_data by LoggedLiteLLMParams keys and litellm_metadata,
where the Responses API stores request metadata including
standard_logging_guardrail_information, was not among them. It fell
into optional_params, so merge_litellm_metadata never saw it. Add
litellm_metadata to LoggedLiteLLMParams so it routes into
litellm_params the same way metadata does on the chat completions path

Fixes #28971.

* fix(proxy): handle non-standard SSE frames in Anthropic passthrough logging (#26000)

Some third-party Anthropic-compatible providers emit non-standard SSE
frames (OpenAI-style [DONE] sentinels, non-JSON keep-alive lines) in
streaming responses. These caused json.JSONDecodeError in
_build_complete_streaming_response, breaking the passthrough logging
pipeline so the request was never logged or billed.

Skip whole-line 'data: [DONE]' sentinels and catch JSONDecodeError per
event. Matching the full line (not a substring) keeps a valid chunk
whose text payload contains '[DONE]' from being dropped.

or not. This still uses the `record_content` property as well, but
both have to be true in order for content to be included.

* fix(logging): translate Responses bridge result to ModelResponse for spend logs (#28985)

PR #29394 fixed the AnthropicResponse.model_validate crash for the streaming
anthropic_messages -> OpenAI Responses bridge by unwrapping terminal events
and returning the inner ResponsesAPIResponse. The spend_logs row lands and
usage/cost are correct, but the row's response field stores the Responses
API shape (output[...].content[...].text). The proxy UI Logs tab reads
response.choices[0].message via parseMessages in prettyMessagesUtils.ts
with no fallback for the Responses shape, so the OutputCard renders "No
response data available" for every cross-routed call. The same shape
mismatch affects every downstream consumer of spend_logs that assumes the
canonical chat-completion shape

This change keeps the unwrap from #29394 but routes the resulting
ResponsesAPIResponse (and the bare-response non-streaming path) through
LiteLLMResponsesTransformationHandler.transform_response, which is the
same conversion already used by the chat-completion Responses bridge.
Spend_logs now stores a ModelResponse with choices[0].message.content, so
the UI and other consumers see the assistant text. On a translation
failure (eg. empty output on an incomplete response) the handler falls
back to a minimal ModelResponse carrying model and usage so the row still
lands rather than being dropped as a Non-Blocking error

Also corrects a stale comment in the Responses adapter that implied the
call type was reclassified to acompletion; the code preserves
anthropic_messages and the success handler translates back to
ModelResponse for the row

Fixes #28595

* fix(anthropic-adapter): re-emit first delta on streaming content-block transitions (#30024)

* fix(anthropic-adapter): re-emit first delta on streaming content-block transitions

The `/v1/messages` -> `/v1/chat/completions` streaming adapter
(`AnthropicStreamWrapper`) silently dropped the first non-empty delta of
every content block that started via a *transition* (e.g. text -> tool_use ->
text, text -> thinking).

When an upstream chunk both triggers a new content block (its type differs
from the active block) and carries that block's first delta, the wrapper
emitted `content_block_stop` -> `content_block_start` and then only re-queued
the trigger chunk when it was an `input_json_delta` (bundled tool args). The
synthesized `content_block_start` always carries an empty body, so the first
`text_delta` / `thinking_delta` was lost — the client output started from the
second token (e.g. "Hi, how can I help you?" rendered as ", how can I help
you?", or text resuming after a tool call lost its first sentence). This is
especially visible with Claude Code-style clients that consume Anthropic
Messages streaming events strictly.

Fix: re-queue the trigger chunk's translated delta whenever it carries
non-empty content (text/thinking/signature/tool args), via a shared
`_trigger_delta_has_content` helper used by both the sync and async paths.
Empty trigger deltas are still suppressed so no spurious empty
`content_block_delta` is introduced.

Fixes #30014

* test(anthropic-adapter): cover all _trigger_delta_has_content branches

Add a direct parametrized unit test for the re-emit predicate so every delta
type (text/input_json/thinking/signature), the empty-payload guards, and the
malformed/non-delta cases are exercised independently of upstream chunk
translation. Raises patch coverage for the new helper.

* feat: add opt-in healthy_only filter to GET /v1/models (#30130)

* feat: add opt-in healthy_only filter to GET /v1/models

Adds an opt-in `healthy_only=true` query parameter to GET /v1/models and
GET /models that hides models whose backing deployments are all marked
unhealthy by background health checks.

- Add Router.async_get_fully_unhealthy_model_names(), mirroring the
  semantics of get_fully_blocked_model_names(): a model is hidden only
  when every backing deployment is unhealthy and the health state is
  not stale (fail open otherwise).
- Reuses the existing DeploymentHealthCache populated by
  _run_background_health_check(), so no new health state is introduced.
- No-op when allowed_fails_policy is set, mirroring
  _async_filter_health_check_unhealthy_deployments semantics.
- team_public_model_name aliases are aggregated alongside model_name.
- Hiding is presentation-only; default behavior is unchanged.

* Dedupe team soft budget alerts by team_id instead of token (#30097)

_team_soft_budget_check sends type="soft_budget" alerts with
event_group=TEAM, but SoftBudgetAlert.get_id always returned the
request token. The alert cache key was therefore scoped per virtual
key, so every active key in a team over its soft budget fired its own
alert within budget_alert_ttl. Branch on event_group so team-level
alerts dedupe by team_id, matching TeamBudgetAlert, while key and
project level alerts keep per-token dedupe.

Fixes #27398.

* feat(bedrock guardrails): support contextual grounding qualifiers (request-side) (#30057)

* test: add failing tests for Bedrock contextual grounding (request-side)

Drive the request-side of Bedrock contextual grounding: callers tag message
content blocks as grounding_source/query, the post_call hook assembles an
ApplyGuardrail(OUTPUT) call carrying source + query + response(guard_content),
and the bedrock converse transform must render the tags as prompt text instead
of silently dropping them. Non-grounding payloads must stay byte-identical.

* feat(bedrock guardrails): support contextual grounding qualifiers

Bedrock contextual grounding scores a model response against a reference
source and the user query, expressed via a per-content-block `qualifiers`
array on ApplyGuardrail. The guardrail hook previously sent plain text only,
so grounding could not be driven through it even though the response-side
contextualGroundingPolicy parsing already existed.

Callers now tag message content blocks `{"type":"grounding_source"}` /
`{"type":"query"}` (mirroring the existing `guarded_text` marker). On the
generate path the bedrock converse transform renders them as plain text; at
post_call the hook harvests them from the request and assembles one
ApplyGuardrail(OUTPUT) call carrying grounding_source + query + the response
(as guard_content). Requests without these tags produce a byte-identical
payload, so existing behaviour is unchanged.

* fix(github_copilot): normalize per-event item_id in /responses streaming (#30072)

GitHub Copilot's native /v1/responses stream assigns a different item_id to
every event of a single output item (output_item.added, the part.added /
delta / done events, and output_item.done). Spec-strict clients like the
Vercel AI SDK key streaming parts by item_id and abort with
"reasoning part <id> not found" / "text part <id> not found" when a delta
references an unregistered id.

Override transform_streaming_response in GithubCopilotResponsesAPIConfig to
anchor every event of an output item to the id from its output_item.added.
Copilot accepts that id paired with the final encrypted_content on the next
turn, so multi-turn replay is unaffected.

* feat: add /model/block and /model/unblock endpoints (#30125)

* feat: add /model/block and /model/unblock endpoints

Add dedicated proxy-admin POST /model/block and /model/unblock endpoints
over the existing blocked flag on LiteLLM_ProxyModelTable, mirroring the
/key/block and /key/unblock pattern. Calling a model whose deployments are
all blocked now returns a clear 403 "Model is blocked" instead of a generic
no-deployment error, including direct-dispatch route types (e.g. eval) via a
pre-route guard. Includes audit-log entries for block/unblock and unit tests.

Keep the SDK Router's documented behavior for blocked deployments (filtered ->
"no healthy deployment") and move the 403 PermissionDeniedError into the proxy
layer (route_llm_request), where model blocking is an admin concept. This avoids
a backwards-incompatible 403 for SDK users who set blocked=True on their own
deployments, per maintainer review.

* fix: add week unit support to get_next_standardized_reset_time (#30100)

* fix: add week unit support to get_next_standardized_reset_time

The function handled d/h/m/s/mo units but silently fell through to
the default next-midnight branch for the w (week) unit. This was
inconsistent: _extract_from_regex already accepted w in its character
class, and duration_in_seconds already returned value * 604800 for it.

Add the missing elif unit == 'w' branch that delegates to
_handle_day_reset with value * 7, which reuses the existing Monday-
alignment logic for 1w and the generic N-day-from-midnight path for
larger multiples.

Add test_week_based_resets covering 1w from a Wednesday (expects next
Monday) and 2w from a Monday (expects 14 days forward at midnight).
