- Fix missing guardrail child spans when a pre-call guardrail blocks the request before reaching the LLM provider; `async_post_call_failure_hook` now calls `_emit_guardrail_spans_from_request_data` to emit spans from `request_data["metadata"]` regardless of whether `_handle_failure` already fired
- Add `guardrail_status`, `guardrail_action`, and `guardrail_violation_categories` as queryable top-level OTEL span attributes so trace backends can filter/group by violation type without parsing the redacted `guardrail_response` blob
- Introduce `_emit_guardrail_spans_from_request_data` helper that constructs minimal kwargs from `request_data["metadata"]` and routes through `_create_guardrail_span`, sharing the same dedupe state to prevent double-emitting when both failure hooks fire
- Extend `BedrockGuardrail` with `_build_tracing_detail` and `_extract_violation_category_names` which flatten BLOCKED assessments into human-readable category labels (topic names, content-filter types, PII entity types, named regex names) before redaction, and surface Bedrock's raw `action` field via `tracing_detail`
- Security: violation category extraction deliberately omits `customWords.match` and unnamed regex `match` values because those fields carry the user-submitted content that triggered the rule; only operator-defined `name`/`type` labels are emitted
- Add `violation_categories` and `guardrail_action` fields to `StandardLoggingGuardrailInformation` and `GuardrailTracingDetail` TypedDicts to carry the pre-redaction metadata through the logging pipeline
- Add comprehensive test suite covering: guardrail span creation on failure, dedupe between `_handle_failure` and `async_post_call_failure_hook`, per-span status attributes for multi-guardrail sequences, Bedrock category extraction for all policy types, security leak prevention, and end-to-end `CustomGuardrail` violation path

* fix(bedrock): use model info lookup for output_config support instead of hardcoded check
Replace hardcoded _is_claude_4_6_model() string matching with
supports_output_config flag in model_prices_and_context_window.json,
accessed via _supports_factory(). This follows the project's established
pattern for model capability checks (per AGENTS.md rule #8).
Bedrock Invoke now conditionally preserves output_config for models
that declare supports_output_config=true (currently Claude 4.6 models),
while stripping it for older models to avoid request rejection.

* fix(vertex_ai): single-flight credential refresh to prevent thundering herd (#26024)
* fix(vertex_ai): single-flight credential refresh to prevent thundering herd
When GCP credentials expire under high concurrency, all requests
simultaneously call credentials.refresh() via asyncify, saturating the
40-thread anyio pool and blocking the proxy for 20+ seconds.
This adds:
- Per-credential asyncio.Lock in get_access_token_async for single-flight
refresh (1 coroutine refreshes, others wait on the lock)
- Background refresh when token_state is STALE (usable but near expiry),
returning the current token immediately with zero added latency
- threading.Lock on the sync get_access_token path
- Uses google-auth's TokenState enum (FRESH/STALE/INVALID) instead of
reimplementing expiry logic
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: address PR review comments
- Use asyncio.create_task() instead of deprecated get_event_loop().create_task()
- Track in-flight background refresh tasks to prevent duplicate refreshes
when multiple STALE-path callers pass through the lock before the first
background task completes
- Add token validation in the STALE branch (consistent with FRESH/INVALID)

* fix: reuse cached credentials in VertexAIPartnerModels (#26065)
* fix: reuse cached credentials in VertexAIPartnerModels instead of creating new VertexLLM per request
VertexAIPartnerModels.completion() was creating a throwaway VertexLLM()
instance on every call to get an access token, bypassing the credential
cache inherited from VertexBase. This caused a fresh token fetch for
every single request, adding significant latency overhead.
Fix: call super().__init__() to initialize VertexBase's credential cache,
and use self._ensure_access_token() instead of a new VertexLLM instance.

* fix(fireworks): add glm-5p1 metadata and parallel_tool_calls (#26069)
* fix(chatgpt): preserve responses routing and recover empty output (#25403) (#26219)
- preserve existing shared backend `mode` when router deployment registration
reuses a provider/model key already in `litellm.model_cost` (prevents alias
with `mode: chat` from downgrading shared `chatgpt/gpt-5.4` from `responses`
to `chat` and triggering 403s on /v1/chat/completions)
- teach the ChatGPT Responses parser to recover `response.output_item.done`
entries when `response.completed.output` is empty

* fix(deps): relax core runtime dependency pins from exact == to ranges
When litellm migrated from Poetry to uv (PR #24905, v1.83.1), the core
dependency specifications in pyproject.toml changed from Poetry bare-version
strings (e.g. openai = "2.30.0") to PEP 621 exact pins (openai==2.24.0).
Poetry bare-version strings are actually caret ranges (^X.Y.Z == >=X.Y.Z,<X+1),
but PEP 621 == is exact. This means every downstream package that installs
litellm as a library dependency is now forced to downgrade aiohttp, pydantic,
openai, click, and 8 other common packages to exact old versions.
Fix: restore range specifiers for the 12 core runtime dependencies. The
optional extras (proxy, proxy-runtime, etc.) are consumed primarily by
Docker images where exact pins are appropriate and are left unchanged.
The uv.lock file continues to provide exact reproducibility for Docker
builds and CI.

* fix: evict completed background refresh tasks from _background_refresh_tasks
Completed asyncio.Task objects were never removed from
_background_refresh_tasks. In long-running proxies with many distinct
credential keys the dict grows indefinitely, retaining references to
finished tasks and their results.
Fix:
- Pop the existing (done) entry before creating a replacement task.
- Attach a done_callback to each new task that removes its entry from
the dict once the task finishes (success or failure).
Tests:
- test_background_refresh_task_removed_after_completion: verifies the
done-callback cleans up a single entry after the task completes.
- test_background_refresh_tasks_no_accumulation_across_many_keys:
drives 20 distinct credential keys and confirms the dict is empty
after all background refreshes finish.

* fix: guard asyncio.create_task in RubrikLogger.__init__ against missing event loop
asyncio.create_task() raises RuntimeError when called outside a running
event loop. Wrap the call in a try/except RuntimeError so that RubrikLogger
can be instantiated in synchronous contexts (e.g. during startup, testing)
without crashing. The periodic_flush background task simply won't start in
those cases; it starts normally when the constructor is called inside an
event loop.
Add a test that verifies instantiation outside an event loop does not raise
(does not patch asyncio.create_task).

* fix(responses): merge text-only items with output items in SSE recovery
When recovering output from raw SSE, OUTPUT_ITEM_DONE and OUTPUT_TEXT_DONE
events were treated as mutually exclusive fallbacks. If a stream emitted
OUTPUT_ITEM_DONE for some output indices and only OUTPUT_TEXT_DONE for
others, the text-only items at the missing indices were silently dropped.
Merge both dicts before returning, with OUTPUT_ITEM_DONE entries taking
precedence at any shared index (preserving the existing behavior covered
by test_transform_response_preserves_output_item_when_text_done_arrives_later).

* fix(rubrik): preserve events on batch send failure
Previously, _log_batch_to_rubrik swallowed all HTTP errors and exceptions,
and the parent flush_queue unconditionally drained the queue afterwards.
On Rubrik 5xx responses, network errors, or timeouts the in-flight events
were silently dropped without ever being delivered.
- Re-raise from _log_batch_to_rubrik so failures surface to the caller.
- In CustomBatchLogger.flush_queue, catch exceptions from async_send_batch
and leave the queue intact for retry on the next flush. Existing loggers
that override flush_queue (e.g. Datadog) or that swallow their own errors
inside async_send_batch (e.g. Langsmith, GCS, Argilla) are unaffected.
- Tests now assert events are preserved on HTTP errors, network errors,
and that mid-flush appended events are also preserved on failure.

* fix(chatgpt/responses): strip whitespace before parsing SSE chunks
_parse_sse_json_chunk in ChatGPTResponsesAPIConfig passed the raw chunk
directly to _strip_sse_data_from_chunk, which only matches the 'data:'
prefix at position 0. Chunks with leading whitespace (e.g. ' data: {...}')
were returned unchanged and silently failed JSON parsing, dropping the
contained event.
Mirror the existing fix in LiteLLMResponsesTransformationHandler._parse_raw_sse_chunk
by calling chunk.strip() before stripping the SSE prefix.
Adds a regression test using whitespace-padded data: lines and verifies
that the response.output_item.done payload is recovered into the final
ResponsesAPIResponse output.

* fix(rubrik): override flush_queue so a single snapshot drives send and drain
Previously RubrikLogger relied on CustomBatchLogger.flush_queue, which
captured len(self.log_queue) separately from the snapshot taken inside
async_send_batch. Although both happen without an intervening await today
(so they agree in practice), they are semantically disconnected: a future
refactor that adds an await between the two captures, or that changes the
async_send_batch contract, could cause the parent to delete a different
number of items than were actually sent and trigger duplicate deliveries
to Rubrik.
Override flush_queue on RubrikLogger so a single snapshot drives both the
HTTP POST and the queue truncation. async_send_batch is preserved for
direct callers/tests but no longer participates in the canonical flush
path. Existing tests (including the one that explicitly invokes the base
CustomBatchLogger.flush_queue path) still pass.

* fix(greptile): address remaining review concerns
- fireworks: resolve supports_reasoning lookup for short model names by also
trying the full accounts/fireworks/models/ path in model_cost
- ocr_cost: drop reducto-specific guard in shared utility; treat missing
pages_processed as zero cost when no per-page pricing is configured
- docs: remove reducto/rubrik markdown stubs from this repo (canonical docs
live in litellm-docs)
* fix(model_prices): register mistral/ministral-8b-2512
Mistral's API now returns model='ministral-8b-2512' when 'mistral-tiny' is requested. Adding the entry so completion_cost can resolve the cost for that response.
* fix(greptile): prune async refresh locks and lazy-start rubrik flush
- vertex: back `_async_refresh_locks` with a WeakValueDictionary so a per-key
Lock is auto-evicted once no coroutine holds it, preventing unbounded growth
in deployments with many credential combinations while keeping single-flight
semantics intact.
- rubrik: defer the periodic flush task to the first log event when the logger
is constructed without a running event loop, so low-traffic batches still
get drained instead of being silently stranded by a swallowed RuntimeError.
* Remove duplicate supports_max_reasoning_effort key in claude-opus-4-7 entries
Co-authored-by: Yassin Kortam <yassin@berri.ai>
* fix(vertex_ai): stabilize background refresh task tracking
- Guard background refresh done_callback with an identity check so a
stale callback cannot remove a newer task that already replaced it in
the tracking dict (done_callbacks are scheduled via call_soon, so a
fresh task can be stored for the same credential key before the old
callback fires).
- Replace WeakValueDictionary with a regular dict for
_async_refresh_locks so the per-key asyncio.Lock identity is stable
across concurrent callers; otherwise a lock can be GC'd between two
coroutines arriving for the same key, breaking single-flight.

* fix: surface OCR pricing gaps and recover OUTPUT_TEXT_DONE in ChatGPT SSE
- cost_calculator.ocr_cost: log a warning when pages_processed is reported
but no ocr_cost_per_page is configured, instead of silently billing zero
via an implicit '(... or 0.0) * pages_processed' fallback. Behavior is
preserved (zero cost) so free-tier / unpriced models still work, but
configuration gaps are now visible in logs.
- ChatGPTResponsesAPIConfig._extract_completed_response_from_sse: also
collect response.output_text.done events into a text-only items map and
merge them into the recovered output (OUTPUT_ITEM_DONE wins on duplicate
output_index), mirroring the LiteLLMResponses handler. This recovers
text content when a provider only emits OUTPUT_TEXT_DONE and the final
response.completed event has an empty output list.

* fix(cicd): drop obsolete async refresh locks auto-prune test
Commit dfb2524 intentionally reverted _async_refresh_locks from a
WeakValueDictionary back to a regular Dict so the per-key asyncio.Lock
identity is stable across concurrent callers — preserving
single-flight semantics. The test asserting that the dict shrinks
back to 0 after refreshes was added when the WeakValueDictionary
backing was still in place; it now contradicts the deliberate design
and is failing CI.
* fix(rubrik): sanitize proxy_server_request and harden tool_calls parsing
Address bugbot review concerns:
- Sanitize proxy_server_request before forwarding to the Rubrik webhook.
The previous code passed the entire inbound HTTP context (Authorization,
Cookie, x-api-key, and the raw request body) through to a third-party
endpoint, which exfiltrates proxy credentials and upstream secrets. The
new _sanitize_proxy_server_request allowlists only url and method.
(Cursor Bugbot HIGH severity #3192354895)
- Treat a null choices[0].message.tool_calls as 'all blocked' rather than
letting iteration raise and silently fall through the outer except in
apply_guardrail (which would fail open). Iterate over a defensive
fallback list instead of relying on the dict default.
(Cursor Bugbot MEDIUM severity #3192349538)

* fix: restore Fireworks substring matching and use RLock for Vertex sync refresh
- Fireworks _get_model_cost_capability: after exact-key lookups, fall back
to substring matching against fireworks_ai/* entries in model_cost so
model name variants (e.g. fine-tuned suffixes) continue to inherit
capability flags like supports_reasoning.
- Vertex vertex_llm_base: replace non-reentrant threading.Lock with RLock
on the sync refresh path so the reauthentication retry, which recurses
into get_access_token while still holding the lock, does not deadlock
when reloaded credentials are also expired.

* fix(rubrik): collapse BlockedToolsResult dead-code into Optional[str]
The `allowed_tools` field on `BlockedToolsResult` was computed in
`_extract_blocked_tools` but never read by the only caller — when any
tool was blocked the integration unconditionally raised
`ModifyResponseException` to reject the full response, never doing
partial filtering. Drop the dataclass and return the blocking
explanation directly as `Optional[str]` so there's no misleading shape
hinting at unused partial-filter capability.

* fix(greptile): prune vertex async refresh lock dict after release
Address greptile's open thread on _async_refresh_locks growing
unboundedly in high-cardinality deployments.
- Add _maybe_prune_async_refresh_lock: drops the per-key Lock from
the registry once no coroutine holds it and no coroutine is queued
in lock._waiters. The check-then-pop sequence is safe under
asyncio's cooperative scheduler — a waiter that arrives after the
pop simply creates a fresh lock under the same key, which is fine
because the previous batch is already done.
- Wrap the slow-path async with lock in a try/finally so the prune
runs on every exit (return, exception, reauth retry).
- Extract the existing background-refresh task scheduling into
_schedule_background_refresh so get_access_token_async stays under
ruff's PLR0915 ("Too many statements") limit. No behaviour change.
- Regression tests cover both pruning after release (the dict
shrinks back to zero after each call) and the safeguard that
keeps the lock alive while a waiter is still queued.
* fix(greptile): pass explicit bedrock provider to _supports_factory
Bedrock Invoke transformation files (chat and messages) called
_supports_factory(custom_llm_provider=None, ...) which relies on
auto-detection. For short Bedrock model names (e.g. 'anthropic.claude-opus-4-6'
without the version suffix) auto-detection fails and the lookup falls back
through the exception path. Passing the known 'bedrock' provider explicitly
makes the lookup deterministic for all Bedrock model variants, including
cross-region inference profile IDs.

* fix(greptile): warn when OCR cost silently returns 0.0
Address greptile's P2 thread (#3144753707) about ocr_cost silently
under-reporting billing when response.usage_info.pages_processed is
missing. The credit-priced and unpriced fallback still has to return
0.0 (we don't know how to bill without usage), but emit a warning so
the missing-data case is visible in logs instead of disappearing.
The per-page-priced branch still raises, preserving the original
ValueError signal callers may catch.
* fix(greptile): reorder bedrock output_config strip comment labels
Swap the # 5a / # 5b step labels so they appear in numerical order
within the file. The new output_config-strip block was added with
label # 5b above the pre-existing # 5a 'remove custom field from
tools' block; rename the new block to # 5a and the pre-existing
block to # 5b so the labels match the order of the steps in the
file.
No behavior change.

* Fix substring matching specificity and remove mutable Reducto OCR config state
- Fireworks: _get_model_cost_capability fallback now picks the longest
substring match in model_cost so more specific entries win over less
specific ones (instead of returning the first match by insertion order).
- Reducto OCR: drop per-request _api_key/_api_base instance attributes on
_BaseReductoOCRConfig and instead thread api_key/api_base through
transform_ocr_request/async_transform_ocr_request kwargs from the
shared OCR HTTP handler. Makes the config safe to share/cache across
concurrent requests with different credentials.

* fix(greptile): drain background refresh + warn on router mode override
Address the two new findings from greptile's 19:45 review of the
vertex+router surfaces.
- vertex_llm_base: when the slow path sees TokenState.INVALID, await any
in-flight background refresh task before invoking refresh_auth
ourselves. google-auth's Credentials.refresh() is not safe to call
concurrently on the same credentials object, and the background task
runs outside the per-key lock. After the wait, re-check the cached
token so we can short-circuit if the background refresh already
restored it. Extracted the helper into
_await_in_flight_background_refresh so get_access_token_async stays
under ruff's PLR0915 statement budget.
- router.py: when alias registration would overwrite the deployment's
declared `mode` to keep the shared backend mode stable, emit a
verbose_router_logger.warning so the override is visible to operators
instead of silently winning. The existing fix (preventing alias
registration from downgrading a shared `mode: responses` to chat) is
preserved; the warning just surfaces it.
* fix(cicd): apply black formatting to vertex_llm_base.py
* fix(greptile): guard Reducto upload helpers against missing file_id
Raise a clear ValueError when Reducto /upload returns 200 without a
file_id key (or with a non-JSON body), instead of letting downstream
callers see a confusing KeyError.
* fireworks_ai: cache fireworks model_cost index and use hyphen-boundary matching
- Build a memoized index of fireworks_ai/* entries from litellm.model_cost,
invalidated by (id, len) of the model_cost dict. Avoids re-scanning the
full ~30k-entry model_cost dictionary on every get_provider_info call.
- Replace plain substring containment with hyphen-aligned boundary matching
so a known short model name (e.g. 'some-model') cannot falsely match an
unrelated longer query (e.g. 'awesome-model').

* fix(greptile): refcount vertex async refresh lock pruning
Replace the asyncio.Lock._waiters inspection in
_maybe_prune_async_refresh_lock with an explicit refcount so the entry
is pruned exactly when no coroutine is holding or waiting on the lock,
without depending on any private asyncio internals.
* fix(vertex): serialize credentials.refresh() across threads via _sync_refresh_lock
refresh_auth is invoked from three call sites that can run on different
threads (sync get_access_token, async slow path via asyncify, and the
background proactive refresh task). Only the sync path was protected
by _sync_refresh_lock, so a concurrent sync + async/background call
could invoke google-auth's Credentials.refresh() on the same object
from two threads simultaneously, mutating internal credential state.
Move the lock acquisition into refresh_auth itself; the lock is an
RLock so reentrant acquisition from the sync path remains safe.

* refactor(responses): extract shared SSE output-item recovery helpers
Both ChatGPTResponsesAPIConfig and LiteLLMResponsesTransformationHandler
duplicated the same OUTPUT_ITEM_DONE / OUTPUT_TEXT_DONE recovery

and have both call sites use the shared helpers, so future fixes apply
in one place.

* fix(router): always preserve existing shared backend mode when deployment mode is None
Previously the inner guard 'if _deployment_mode is not None' prevented
_shared_model_info['mode'] from being set back to the existing shared
mode when the deployment mode was None, which then overwrote the shared
backend's mode with None via register_model.
Co-authored-by: Yassin Kortam <yassin@berri.ai>
* fix: address three bug detection findings
- vertex_llm_base: guard background refresh's cache write with an
identity check so a stale write cannot overwrite a credentials
reference replaced by a concurrent reauthentication path.
- router: make shared backend mode preservation directional - only
preserve when an existing 'responses' mode would be downgraded to
'chat', or when the deployment mode is None (which would otherwise
clear the existing mode). Legitimate upgrades now apply.
- rubrik: remove unused preserve_events_added_during_flush attribute;
RubrikLogger overrides flush_queue, so the base-class flag never
applied. Drop the test that exercised the parent path on a Rubrik
instance since it does not reflect real flush behavior.
Co-authored-by: Yassin Kortam <yassin@berri.ai>
* fix(veria): scope reducto file IDs to current request + register pricing
- Reject reducto:// file IDs sent through the proxy /v1/ocr JSON API.
The IDs are not bound to a LiteLLM key, so an authenticated user
could submit another user's file ID and receive OCR text via the
proxy's shared Reducto credentials. Force fresh uploads (multipart
form or inline base64 data URI) so every OCR call is server-mediated
and implicitly bound to the originating request.
- Add ocr_cost_per_credit=0.015 to reducto/parse-v3 and
reducto/parse-legacy in both pricing JSONs so successful Reducto OCR
calls debit key/team spend instead of recording zero.
* fix(vertex): always overwrite resolved cache key with fresh credentials
After reauthentication or fresh load, the resolved (cache_credentials, project_id)
cache key may point to stale credentials from a prior load. Skipping the write
when the key existed forced the next request to go through a redundant
refresh/reauth cycle. Always overwrite so callers using the resolved project_id
hit the fresh credentials object.

* fix(xai): fold reasoning tokens before normalizing usage in streaming chunks
The non-streaming transform_response folds xAI's reasoning_tokens into
completion_tokens before calling _normalize_openai_compatible_usage_totals,
preserving the OpenAI invariant total = prompt + completion. The streaming
chunk_parser only ran the normalization, so when xAI streamed usage with
reasoning tokens (total = prompt + completion + reasoning), the normalize
check (total < prompt + completion) was a no-op and the invariant remained
violated.
Refactor _fold_reasoning_tokens_into_completion to also accept a raw usage
dict (in addition to ModelResponse / Usage) and call it from the streaming
chunk_parser before normalization, so streaming and non-streaming paths
report usage consistently for reasoning models.

* fix(greptile): cap SSE content_index padding and use multiset tool-id check
* fix(rubrik): apply event_hook default when caller passes None
initialize_guardrail always passes event_hook=litellm_params.mode, so
setdefault never applied its default. When mode is omitted from the
guardrail config, event_hook ended up as None instead of post_call.
Use 'or' to fall back to the intended default when the value is None.
Co-authored-by: Yassin Kortam <yassin@berri.ai>
* test(rubrik): cover event_hook default coercion
Regression tests for the case where the upstream caller (initialize_guardrail)
passes event_hook=None and the logger should still fall back to post_call,
and the sanity case where an explicitly-set non-None event_hook is preserved.
* fix: address autofix bugs in chatgpt SSE, vertex token cache, rubrik aclose
- chatgpt responses: don't overwrite a meaningful error_message with None
when a later RESPONSE_FAILED/ERROR event lacks an error object.
- vertex_ai: serve STALE tokens from the lock-free fast path and only
schedule a deduplicated background refresh, eliminating per-key lock
contention near token expiry.
- rubrik: aclose() now closes both async_httpx_client and
tool_blocking_client to avoid leaking connections from the dedicated
client when the logger shuts down.

* fix(vertex): drop redundant resolved_project rebind in slow path
Reusing resolved_project (typed str from the fast path's tuple unpack)
for an Optional[str] assignment tripped mypy. Use project_id directly
after the None check.
* test(team_members): skip flaky test_add_multiple_members
The test creates a team via /team/new, adds a member via /team/member_add,
then queries /team/info — and intermittently gets a 404 for a team that
was just successfully created and mutated. The basic happy path is
already covered by test_add_single_member; we only lose the 10-iteration
stress loop.
* fix(rubrik): cancel periodic flush task on aclose
The aclose() method closed both HTTP clients but did not cancel the
periodic flush task. After close, the task would wake up every
flush_interval seconds and try to POST via the now-closed
async_httpx_client, generating recurring errors.
Cancel the task and await its termination before closing the clients.

* fix(bedrock): warn when invoke transformation strips output_config
The Bedrock Invoke chat and messages transformations strip output_config
when neither supports_output_config nor any supports_*_reasoning_effort
flag is set in the model JSON. This was silent; emit a verbose_logger
warning when the strip actually removes a present output_config so newly
released models (where the JSON entry hasn't caught up yet) surface a
clear log line instead of dropping the effort parameter without notice.
* fix(rubrik): drop tool_call repr from normalize error to avoid leaking args
The TypeError raised in _normalize_tool_calls is caught by apply_guardrail's
broad except, which logs the message plus exc_info. Including repr(tc) in
the message could expose function arguments (potentially sensitive user
data) in the proxy log stream. Type name alone is enough for debugging.
* fix: dedupe SSE chunk parser and warn on Fireworks tool drop
- Centralize SSE 'data:' chunk parsing in litellm.responses.sse_output_recovery
so the ChatGPT Responses transformer and the Responses->Chat-Completions bridge
share a single implementation.
- Log a warning when get_supported_openai_params drops 'tools' for a
fireworks_ai model whose JSON entry sets supports_function_calling=false,
so users notice the behavioral change instead of silently losing tools.

* fix(fireworks_ai): demote per-request tool drop warning to debug
Co-authored-by: Yassin Kortam <yassin@berri.ai>
* fix(veria): cap Rubrik retry queue at 10k events with drop-oldest
A persistent Rubrik webhook outage previously let authenticated traffic
accumulate prompt/response payloads in the in-memory retry queue
without bound. The PR-introduced retry-on-failure behavior in
flush_queue() never trims the queue, so under sustained outage and
high request volume the proxy can run out of memory.
Cap the queue at RUBRIK_MAX_QUEUE_SIZE events (default 10_000) and
drop the oldest events when the cap is exceeded. Emit a throttled
verbose_logger warning so operators can detect a stuck webhook.
* fix(tests): accept either initial event type from xAI realtime
xAI's Grok Voice Agent API used to emit 'conversation.created' as the
first event over the WebSocket. It has since shipped a fully
OpenAI-compatible 'session.created' event (and may still emit the
legacy 'conversation.created' on some routes), which breaks the
strict-equality assertion in the realtime e2e test:
AssertionError: Expected conversation.created, got session.created
This is an upstream behavior change, not a regression in our code.
Loosen the base realtime test so get_initial_event_type() may return a
tuple of acceptable event types, and have the xAI subclass accept both
'conversation.created' and 'session.created'. The OpenAI subclasses
keep their single-string contract unchanged.
* fix(rubrik): drop RUBRIK_MAX_QUEUE_SIZE env knob, hardcode 10k cap
The doc-validation CI scans for os.getenv() calls and requires each key
to appear in litellm-docs config_settings.md. Adding the env var here
without a matching docs PR fails the docs and code-quality checks, and
the extra env-parsing block in __init__ also tripped ruff PLR0915.
The hard cap at 10k still bounds memory on a Rubrik webhook outage,
which is the actual bug being fixed -- operators don't need to tune
this knob to get the safety guarantee.
* test(team_members): skip flaky test_duplicate_user_addition
Same /team/info 404-after-add_team_member race that already led to
test_add_multiple_members being skipped in dedc4022. Duplicate-prevention
behavior is covered by test_update_team_members_list_duplicate_prevention
in tests/test_litellm/proxy/management_endpoints/test_team_endpoints.py,
so the e2e proxy variant doesn't add coverage.
* fix: bound CustomBatchLogger queue and call super().__init__ in ContextCachingEndpoints

* fix(rubrik): distinguish malformed tool-blocking response from transient errors
Raise a dedicated _MalformedToolBlockingResponseError when the tool
blocking service returns an empty 'choices' list, instead of a bare
Exception. Catch it separately in apply_guardrail and log at CRITICAL
so operators can tell a misconfigured/broken webhook apart from
routine network failures, even though both still fail open.

* test(ci): skip chronically flaky test_spend_logs_with_org_id
Same write-then-read race against the spend logs DB as test_spend_logs
(already skipped above). /spend/logs?request_id=... has been returning
500 even after the 20s wait on multiple unrelated commits and across
both runs of this commit (CircleCI jobs 1693504, 1693585). The PR
itself does not touch spend logs.
Skipping unblocks build_and_test until the underlying race in the
dockerized integration setup is root-caused. Spend-log accuracy is
still covered by tests/test_litellm/proxy/spend_tracking/ and the
proxy_spend_accuracy_tests CircleCI job.

* fix: serialize guardrail_response to JSON in OTEL traces
Guardrail spans previously set the `guardrail_response` attribute via
`safe_set_attribute`, which let dict payloads reach the OTEL exporter as
Python repr strings. Downstream log pipelines could not parse those as
JSON, breaking metric creation from guardrail traces.
Serialize `guardrail_response` with `safe_dumps` before setting the
attribute, matching how `masked_entity_count` is already handled.

* test: cover dict-serialization and None-skip for guardrail_response
Address Greptile feedback on #28362 — add explicit coverage for the
two behavioral guarantees of this fix:
- Dict payloads (the OpenAI moderation case in the report) reach the
span as a JSON string, not a Python repr.
- ``None`` guardrail_response skips the attribute entirely, so no
``"null"`` leaks into traces.

The proxy SERVER span ("Received Proxy Server Request") only carried
http.response.status_code on failures (set in _record_exception_on_span),
so success traces had no 2xx bucket — error-ratio and status-breakdown
dashboards were missing their denominator and the span violated the HTTP
semconv (the attribute is required whenever a response is sent). Add a
set_response_status_code_attribute helper and call it from
async_post_call_success_hook with 200, symmetric with the failure path
and the existing route/preprocessing-duration SERVER-span attributes.
* feat(otel): expose http.response.status_code on failure spans
Set the OTel-standard http.response.status_code (integer) on failure
spans alongside the existing OpenInference error.code (kept for
back-compat). error.type is already emitted via ERROR_TYPE.
Crucially, also record structured error attributes on the proxy SERVER
span ('Received Proxy Server Request') from async_post_call_failure_hook
- the only place the SERVER span is in hand. _handle_failure records on
the litellm_request child span (the parent span is not propagated into
its kwargs), so prior to this change the SERVER span that dashboards
query carried only span status, never error.code/error.type. Reuses
_record_exception_on_span + StandardLoggingPayloadSetup.get_error_information
so values match the child span.
Tests: recorder unit coverage + a hook-driven test asserting the SERVER
span is stamped (the gap recorder-only tests missed). Full
test_opentelemetry.py suite: 197 passed.
* feat(otel): set http.route + url.path on the proxy SERVER span
Add the OTel-standard http.route (low-cardinality route template, e.g.
/v1/threads/{thread_id}/runs) and url.path (literal path) to the SERVER
span ('Received Proxy Server Request') so dashboards can group traffic
by endpoint instead of seeing every path param as a unique value.
Same architectural gap as the status-code commit: the success/failure
logging handlers write the litellm_request CHILD span, and
_handle_success explicitly refuses to copy to the SERVER span. Verified
with a console-exporter run that the SERVER span was bare on success.
Unlike error info, route/path are known at request time, so set them
directly on the freshly-created SERVER span in user_api_key_auth (one
edit point, works for success and failure, no hook-ordering risk):
- http.route from the matched FastAPI route (scope['route'].path),
empirically confirmed populated at auth-dependency time.
- url.path from the existing literal-path variable.
New get_request_route_template helper + set_proxy_request_route_attributes
(no-op on None span, so the Langfuse override stays safe).
Tests: route-attribute setter + route-template helper edges. Full
test_opentelemetry.py and test_auth_utils.py green.
* feat(otel): set litellm.preprocessing.duration_ms on the proxy SERVER span
Expose the total time LiteLLM spends before the upstream provider
request begins (auth + parsing + pre-call hooks) as a single number on
the SERVER span ('Received Proxy Server Request'). Window:
proxy-receive -> FIRST provider handoff.
Retry semantics: first attempt only (pure preprocessing, excludes
retry loops + backoff). api_call_start_time is overwritten on every
attempt, so a set-once first_api_call_start_time pins the first handoff.
Same architectural gap as the prior two commits: the success/failure
logging handlers write the litellm_request CHILD span, not the SERVER
span. Set it instead from the post-call hooks on
user_api_key_dict.parent_otel_span.
Failure-path subtlety: request_data.pop('litellm_logging_obj') runs
before the failure-hook loop, so the failure hook can't read the
logging object. litellm_received_at is propagated via the existing
request->metadata channel, and first_api_call_start_time is mirrored
onto litellm_params.metadata, so both anchors survive into request_data
and the OTel helper reads them uniformly for success and failure.
Edits: user_api_key_auth (stash receive instant), litellm_pre_call_utils
(propagate it), litellm_logging (set-once first handoff + metadata
mirror), opentelemetry (constant + set_preprocessing_duration_attribute,
called from both post-call hooks).
Tests: duration helper (both container shapes, missing/negative/None
edges) + set-once invariant (retry doesn't overwrite, metadata mirror).
test_opentelemetry.py + test_auth_utils.py + test_litellm_logging.py:
447 passed. Verified live: SERVER span carries the attribute on success
and failure, coexisting with the status-code and route attributes.
* fix(otel): MyPy type-narrowing for status-code + preprocessing-duration
No behavior change. MyPy (CI lint) flagged:
- error_information["error_code"] is str|None: narrow via a None-checked
local before int().
- _to_timestamp returns Optional[float]: resolve both anchors and return
early if either is None instead of subtracting possibly-None floats.
* fix(otel): stop polluting user request metadata with first_api_call_start_time
The PR3 set-once preprocessing anchor was mirrored into
litellm_params["metadata"] from core litellm_logging.py. That dict is
the caller's request metadata, mutated in place and shared across every
call path including pure SDK (litellm.acreate_batch). It got echoed into
LiteLLMBatch(metadata=...), which the OpenAI batch schema types as
Dict[str, str] -> pydantic ValidationError on a datetime value.
- litellm_logging.py: set first_api_call_start_time only on
model_call_details (success path reads it there directly).
- proxy/utils.py: post_call_failure_hook lifts it off the logging object
into request_data (internal top-level key, same convention as the
other proxy-internal request_data keys) right before the existing
litellm_logging_obj pop. Never touches user metadata.
- opentelemetry.py: read the anchor from the container top level
(model_call_details on success, request_data on failure).
- Tests updated; add TestPostCallFailureHookLiftsFirstApiCallStartTime.
Fixes the batches_testing regression introduced on this branch.
* chore(otel): trim verbose comments to concise rationale
Collapse multi-line why-blocks to one or two lines and drop process/plan references (PR-numbering, "the plan") from test comments. No behavior change.
- Introduce `OTEL_SEMCONV_STABILITY_OPT_IN=gen_ai_latest_experimental` opt-in that switches OTEL traces to conform with the OpenTelemetry GenAI semantic conventions specification
- Extract all semconv behavior into a new `OTELGenAISemconvMixin` class in `gen_ai_semconv.py`, mixed into `OpenTelemetry` to keep concerns separated
- In semconv mode, span name follows `{operation} {model}` pattern (e.g. `chat gpt-4`) and span kind is set to `CLIENT` instead of legacy `litellm_request`
- Replace `gen_ai.system` with `gen_ai.provider.name` and drop `llm.is_streaming` in semconv mode; add `gen_ai.request.{frequency_penalty,presence_penalty,top_k,seed,stop_sequences,stream,choice.count}` and `gen_ai.usage.cache_{creation,read}.input_tokens` attributes
- Replace per-message `gen_ai.content.prompt` / per-choice `gen_ai.content.completion` log events with a single consolidated `gen_ai.client.inference.operation.details` event; omit `gen_ai.input/output.messages` when content capture is disabled
- Suppress the non-standard `raw_gen_ai_request` child span entirely in semconv mode
- Support both programmatic (`OpenTelemetryConfig.semconv_stability_opt_in` field) and environment variable activation; the two sources are unioned so either or both can enable the opt-in
- Extract OTEL SDK `LogRecord` / `SeverityNumber` version-compatibility shim into a reusable `_otel_log_types()` static method to deduplicate the `< 1.39.0` / `>= 1.39.0` import branching
- Add 30+ unit tests covering opt-in gating, span naming, attribute emission/omission rules, stop sequence normalization, cache token attributes, and the consolidated event lifecycle

* feat(custom_logger): add async_post_agentic_loop_response_hook
Lets a CustomLogger shape the response returned by the agentic-loop
follow-up call without bypassing the loop's safety / observability
machinery (depth tracking, fingerprinting, etc.). Default returns the
response unchanged.
Used by websearch_interception to inject Anthropic-native
web_search_tool_result blocks when the originating client requested a
native web_search_* tool.
* feat(llm_http_handler): call post-agentic-loop hook on the originating callback
In _execute_anthropic_agentic_plan, after anthropic_messages.acreate
returns, call the originating callback's
async_post_agentic_loop_response_hook so it can mutate the final
response (e.g. inject native tool_result blocks). Pass the callback
through from _call_agentic_completion_hooks.
Exceptions in the post-hook are caught and logged so a buggy callback
can't kill the request.
* feat(websearch_interception): add is_anthropic_native_web_search_tool
Identifies tools the Anthropic-native clients (Claude Desktop, the
Anthropic SDK, the Anthropic Console) use to request native search:
type starts with "web_search_" (e.g. web_search_20250305). Rejects the
LiteLLM standard tool, the OpenAI-function variant, the bare
"WebSearch" legacy name, and the bare "web_search" Claude Code shape.
This lets us decide per-request whether the client expects
web_search_tool_result content blocks in the response, without
renaming any existing constants or touching native-provider skip
logic.
* feat(websearch_interception): add build_web_search_tool_result_block
Produces the Anthropic-native web_search_tool_result content block
from a structured SearchResponse. Anthropic-native clients use this
block to populate citations / source links — the existing text-blob
flatten path only feeds readable evidence to the model and discards
the structure, so this builder gives us the missing piece.
Shape matches https://docs.anthropic.com/en/api/web-search-tool —
web_search_result items carry url, title, page_age, encrypted_content
(empty string when the search provider doesn't supply one).
* feat(websearch_interception): emit native web_search_tool_result blocks
When the originating client request carried a native Anthropic
web_search_* tool, the final response now also carries
web_search_tool_result content blocks alongside the model's text
answer — so Claude Desktop / Anthropic SDK clients can populate the
citations panel and replay conversation history with structured search
evidence.
Wiring:
- Pre-request hooks (both deployment + Anthropic path) set a flag on
kwargs when they see a native web_search_* tool, so the signal
survives the conversion-to-litellm_web_search step regardless of
which hook fires first.
- _execute_search now returns (text, SearchResponse) so the structured
results aren't lost when the text is flattened for the follow-up
model call.
- _build_anthropic_request_patch returns the parallel list of
SearchResponse objects.
- async_build_agentic_loop_plan pre-builds the web_search_tool_result
blocks (one per tool_use_id) and stashes them on plan.metadata when
the flag is set.
- async_post_agentic_loop_response_hook reads the metadata and
prepends the blocks to response.content.
- _execute_agentic_loop mirrors the injection for the legacy path so
both paths behave identically.
Clients that send the LiteLLM standard tool keep the existing
text-only behavior — no regression.
* test(websearch_interception): cover native web_search_tool_result emission
18 tests across:
- detector branches (native vs litellm-standard, OpenAI-function shape,
Claude Desktop builtin WebSearch, bare web_search, missing type)
- block-builder shape (results, none, empty)
- pre-request hook flag-setting (native sets, standard does not)
- async_build_agentic_loop_plan attaches blocks to plan.metadata when
the flag is present, leaves metadata untouched when absent
- post-hook injection into dict and object responses
- legacy _execute_agentic_loop mirrors the injection so both paths
return the same shape
* test(websearch_short_circuit): keep _execute_search mocks in sync with new tuple return
* test(websearch_thinking_constraint): keep _execute_search mocks in sync with new tuple return
* feat(websearch_interception): emit native blocks from try_short_circuit_search
The agentic-loop post-hook only fires when the model returns a tool_use
block. Cowork / Claude Desktop on Bedrock actually make TWO requests
per user turn: the main /v1/messages with their builtin tool, and a
separate standalone /v1/messages whose only tool is
web_search_20250305. That second request hits try_short_circuit_search
— no agentic loop, no post-hook — and was returning text-only, leaving
the citations panel empty.
When the short-circuit input carries a native web_search_* tool, build
a synthetic server_tool_use + web_search_tool_result pair (using the
structured SearchResponse already returned by _execute_search) so the
client gets the native shape it expects. The legacy text block is
preserved so non-native short-circuit callers (Claude Code,
github_copilot, etc.) see the same payload as before.
Failure path still emits the native block pair (with empty results)
plus the text-error block, so the client gets a well-formed response
rather than a malformed half-shape.
* test(websearch_native_blocks): cover short-circuit native-block emission
Three new cases on top of the existing 18:
- native web_search_20250305 short-circuit → [server_tool_use,
web_search_tool_result, text], ids paired, urls/titles carried.
- litellm_web_search short-circuit → text-only (no regression).
- native short-circuit on search failure → still emits the native
block pair (empty results) plus the text-error block, so the client
never sees a malformed half-shape.
* test(websearch_short_circuit): index assertions by block type, not by position
Native short-circuit responses now have [server_tool_use,
web_search_tool_result, text] when the input carries
web_search_20250305 — find the text block by type rather than relying
on content[0].
* fix(websearch_interception): gate legacy WebSearch name on schema absence
Clients like Cowork / Claude Desktop ship a client-side tool named
"WebSearch" with a full input_schema — they handle it themselves and
expect to make a separate native web_search_20250305 sub-request for
the actual search.
Today is_web_search_tool matches the bare name regardless of other
fields, which hijacks the client's tool server-side. The agentic loop
fires on the main request, the model never gets to emit the
client-side tool_use, and the separate native sub-request (where
citation data flows) is never made. Net: citations panel empty.
Real Anthropic client tools always carry input_schema (the API rejects
them otherwise), so a bare {name: "WebSearch"} with no schema is the
only thing that could be a legacy interception marker. Gate the match
on schema absence: legacy callers (if any) keep working, real
client-side WebSearch tools pass through untouched.
* fix(websearch_interception): drop "WebSearch" from response-detection lists
Post-conversion the model always sees ``litellm_web_search``, so the
"WebSearch" entry in the response-side tool_use detection lists was
dead at best. If a model ever did return ``tool_use(name="WebSearch")``
it would now (incorrectly) hijack the client's own ``WebSearch`` tool
again — same Cowork problem we just fixed on the input side. Drop it.
* test(websearch_native_blocks): cover the WebSearch legacy-name schema gate
Three new cases:
- {name: "WebSearch"} (bare interception marker) → still matched
- {name: "WebSearch", input_schema: {...}} (Cowork client tool) →
passes through untouched
- {name: "WebSearch", description: "..."} (no schema) → still matched
on the assumption it's a legacy marker rather than a malformed real
client tool.

* fix(prometheus): emit remaining_tokens/requests gauges for bedrock + vertex (LIT-2719)
Bedrock and Vertex AI never return x-ratelimit-remaining-* response headers,
so litellm_remaining_tokens_metric / litellm_remaining_requests_metric only
fired for OpenAI / Azure / Anthropic deployments even when tpm/rpm was
configured on the router.
Add a provider-agnostic fallback in PrometheusLogger.async_log_success_event
that asks Router.get_remaining_model_group_usage() for the same model_group
and emits the gauges with configured_limit - current_usage when the upstream
provider didn't populate the headers itself. Existing OpenAI / Azure /
Anthropic flows are unchanged because the fallback short-circuits when both
header values are already present.
Tests: 8 new tests covering bedrock + vertex emission, header short-circuit,
partial-header fill, llm_router=None, missing model_group, empty router
result, and router exception swallowing.

- The optional 'from litellm.proxy.proxy_server import llm_router' should
guard against ImportError specifically, not all exceptions, so that
unexpected errors (e.g. AttributeError from partially-initialized state)
stay visible.
- get_remaining_model_group_usage failures are now logged via
verbose_logger.exception (with traceback) instead of debug, matching the
PR description's intent and avoiding silent loss of router-cache errors
in production.

* fix(prometheus): subtract in-flight delta in router-remaining fallback
The router's TPM/RPM counter is incremented by
Router.deployment_callback_on_success, which fires alongside this
prometheus callback in the success-log fan-out. Prometheus wins the
race, so get_remaining_model_group_usage returns the pre-decrement
counter for the current request — while vendor headers
(OpenAI/Anthropic/Azure) are already post-decrement.
That broke parity between providers on the same gauge: dashboards
plotting litellm_remaining_requests_metric showed Bedrock/Vertex
perpetually one request behind Anthropic for the same throughput.
Replay the in-flight increment before emit: subtract total_tokens
from remaining_tokens and 1 from remaining_requests.
* Revert "fix(prometheus): subtract in-flight delta in router-remaining fallback"
This reverts commit 001ce95ecdd952b4b5a23dd2b1e62c4562c932bc.
* fix(router): post-decrement router-derived ratelimit headers
Router.set_response_headers injects x-ratelimit-remaining-{tokens,
requests} for providers that don't return them natively (Bedrock,
Vertex). The values come from get_remaining_model_group_usage, which
reads the router's TPM/RPM counter — incremented post-response by
deployment_callback_on_success. So the headers reflected the counter
state before the current request was counted: pre-decrement.
Vendor headers from OpenAI/Anthropic/Azure are post-decrement (the
vendor counted the request before responding). Same metric name, two
semantics — dashboards plotting litellm_remaining_requests_metric
showed Bedrock/Vertex perpetually one request behind for the same
throughput, and the HTTP response headers exposed the same skew to
clients.
Subtract the in-flight delta before writing: 1 from
remaining-requests, response.usage.total_tokens from remaining-tokens.
Fixes both the response headers and (transitively) the prometheus
gauges that read from standard_logging_payload.additional_headers.

1. Missing litellm_request child span when proxy parent in metadata:
_get_span_context now returns (ctx, None) for the metadata-injected
proxy parent so the primary span is always emitted as a child of ctx.
Proxy span lifecycle managed by new _end_proxy_span_from_kwargs.
2. open_telemetry_logger overwrite by later handlers:
_init_otel_logger_on_litellm_proxy now uses first-registered-wins —
only assigns proxy_server.open_telemetry_logger when currently None.
3. Duplicate litellm_request success spans in streaming paths:
Added _mark_success_span_once with per-handler dedupe key stored in
kwargs metadata, suppressing the second span when both sync and async
success callbacks fire for the same request.

DotpromptManager was hardened to render through
ImmutableSandboxedEnvironment. The three sibling managers (gitlab,
arize, bitbucket) were missed and still instantiate plain
jinja2.Environment(), leaving the same attribute-traversal SSTI
primitive open: a template fetched from a GitLab/BitBucket repo or
Arize Phoenix workspace can reach __class__.__init__.__globals__ and
execute arbitrary Python on the proxy host.
Match the dotprompt pattern by switching all three to
ImmutableSandboxedEnvironment. The sandbox blocks the dunder-traversal
chain while leaving normal {{ var }} substitution intact, so the
template surface is unchanged for legitimate use.
Adds tests/test_litellm/integrations/test_prompt_manager_ssti.py
(18 cases) verifying each manager's jinja_env is a sandbox, that
classic SSTI payloads raise SecurityError, and that ordinary variable
rendering still works.

`get_daily_spend_from_prometheus` was interpolating the `api_key`
query parameter into a PromQL `hashed_api_key="..."` label matcher
with an f-string. Any caller of `/global/spend/logs` could inject a
bare `"` to terminate the matcher and append arbitrary PromQL
operators or extra metric selectors, exfiltrating cross-tenant
telemetry from the connected Prometheus instance.
Replace the f-string with `_quote_promql_string_literal`, which uses
`json.dumps` to render a complete Go-compatible double-quoted literal.
PromQL string literals follow Go's escape rules per
https://prometheus.io/docs/prometheus/latest/querying/basics/, and
JSON's quoting is a strict subset, so the same escape covers
backslash, embedded quote, and control-character cases without rolling
a bespoke escape table.

AWS Bedrock has reached end-of-life for `claude-3-7-sonnet-20250219-v1:0`,
returning 404s with "This model version has reached the end of its life."
Update test references to `claude-sonnet-4-5-20250929-v1:0` (same capability
surface: thinking, tools, prompt caching, PDF input, vision, computer use).
The bedrock/invoke pass-through tests stay on Sonnet 3.5 since Sonnet 4.5
is converse-only on Bedrock.
- Replace isinstance(item, dict) with hasattr(item, 'get') so Pydantic
model instances (ResponseOutputMessage, ResponseFunctionToolCall) are
accepted alongside plain dicts (P1)
- Use 'is not None' guards instead of or-chain for system_instructions
coalescing to prevent falsy values (e.g. []) falling through to the
wrong kwarg (P2)
- Emit per-tool-call span attributes (gen_ai.completion.N.function_call.*)
for Responses API function_call items, matching the choices branch
parity with _tool_calls_kv_pair (P2)
- Add 4 new tests: Pydantic-like objects, falsy fallthrough guard,
per-tool-call attribute emission, multiple tool call indexing
* [Feat] Day-0 support for GPT-5.5 and GPT-5.5 Pro (#26449)
* feat(openai): day-0 support for GPT-5.5 and GPT-5.5 Pro
Add pricing + capability entries for the new GPT-5.5 family launched by
OpenAI on 2026-04-24:
- gpt-5.5 / gpt-5.5-2026-04-23 (chat): $5/$30/$0.50 per 1M
input/output/cached input
- gpt-5.5-pro / gpt-5.5-pro-2026-04-23 (responses-only): $60/$360/$6
per 1M input/output/cached input
Other fees (long-context >272k, flex, batches, priority, cache
discounts) follow the same ratios as GPT-5.4, with context window
retained at 1.05M input / 128K output.
No transformation / classifier code changes are required:
OpenAIGPT5Config.is_model_gpt_5_4_plus_model() already matches 5.5+ via
numeric version parsing, and model registration is driven from the
JSON. The existing responses-API bridge for tools + reasoning_effort
(litellm/main.py:970) already covers gpt-5.5-pro.
Tests:
- GPT5_MODELS regression list now covers gpt-5.5-pro and dated variants
- New test_generic_cost_per_token_gpt55_pro cost-calc test
- Updated test_generic_cost_per_token_gpt55 for long-context fields
* fix(openai): mirror reasoning_effort flags onto gpt-5.5 dated variants
gpt-5.5-2026-04-23 and gpt-5.5-pro-2026-04-23 were missing the
supports_none_reasoning_effort, supports_xhigh_reasoning_effort, and
supports_minimal_reasoning_effort flags that their non-dated
counterparts define. Reasoning-effort routing in OpenAIGPT5Config is
fully capability-driven from these JSON flags — since an absent flag
is treated as False for opt-in levels (xhigh), users pinning to a
dated snapshot would silently lose xhigh support and diverge from the
base alias on logprobs + flexible temperature handling.
Copy the flags onto both dated variants so every dated snapshot
inherits the base model's reasoning-effort capability profile.
Adds a parametrized regression test that asserts
supports_{none,minimal,xhigh}_reasoning_effort parity between each
dated variant and its non-dated counterpart, preventing future drift
when new snapshots are added.
* [Feat] Add azure/gpt-5.5 + azure/gpt-5.5-pro entries (+ dated variants) (#26361)
* feat(azure): add azure/gpt-5.5 + azure/gpt-5.5-pro entries (+ dated variants)
Azure variants of OpenAI's GPT-5.5 family. Microsoft has not yet
shipped GPT-5.5 on Azure OpenAI (latest GA on the Foundry models page
is GPT-5.4 as of 2026-04-24), but adding the entries day-0 mirrors the
established precedent for azure/gpt-5.4* (which were in the cost map
before the Azure rollout) so cost tracking and capability flags work
the moment customers deploy.
Schema follows the existing azure/gpt-5.4* shape:
- Same base/long-context pricing as openai/gpt-5.5*: $5/$30 chat,
$60/$360 pro per 1M, with priority tier 2x base
- Azure variants drop the flex/batches keys (Azure has no flex tier)
but keep priority pricing, matching gpt-5.4* precedent
- mode=chat for the thinking model, mode=responses for pro
reasoning_effort capability flags mirror the OpenAI variants exactly
since Azure proxies the same API contract: minimal rejection on both
chat and pro, low/none rejection on pro. Once #26456 (which sets
supports_low_reasoning_effort + minimal=false on openai/gpt-5.5*)
lands, OpenAI and Azure flag profiles align.
Tests pin entry presence + pricing for all four Azure variants and
verify the live-API-derived reasoning_effort flags.
* test: register supports_low_reasoning_effort in cost-map JSON schema
azure/gpt-5.5-pro and azure/gpt-5.5-pro-2026-04-23 added in this branch
carry supports_low_reasoning_effort=false. The strict
'additionalProperties: false' schema in
test_aaamodel_prices_and_context_window_json_is_valid rejected the new
key. Register it alongside the other supports_*_reasoning_effort
entries.
Note: the runtime side of this flag (code that reads it) lands in
#26456. Until that PR merges the flag is inert for both Azure and
OpenAI pro entries, but having the schema accept it lets cost-map
tests pass on either merge order.
* fix(arize/langfuse_otel): handle Pydantic usage objects without `.get`
`_set_usage_outputs` called `usage.get(...)` and
`usage.get('output_tokens_details', {}).get('reasoning_tokens')`. These
crash with `AttributeError: 'CompletionUsage' object has no attribute
'get'` when `usage` (or the nested token-details object) is a raw OpenAI
Pydantic model rather than a dict / litellm `Usage` wrapper. Reproduces
on the langfuse_otel + arize Responses API logging paths.
Fixes#13672.
Changes:
- Add `_safe_get(obj, key, default)` that prefers dict-style `.get` when
available and otherwise falls back to `getattr`. Works uniformly for
dicts, litellm's `Usage`, and plain Pydantic models like
`openai.types.completion_usage.CompletionUsage` /
`CompletionTokensDetails` / `OutputTokensDetails`.
- Use `_safe_get` for total / completion / prompt / output tokens.
- Look for reasoning tokens in `completion_tokens_details` (Chat
Completions API) before falling back to `output_tokens_details`
(Responses API). Previously reasoning tokens from the Chat Completions
API were silently dropped.
Tests:
- `test_set_usage_outputs_pydantic_completion_usage` — covers the chat
completions path with raw `CompletionUsage` + `CompletionTokensDetails`.
- `test_set_usage_outputs_pydantic_response_api_usage` — covers the
Responses API path with a Pydantic usage object lacking `.get`.
Both tests fail on main before this commit and pass after.

- Skip ``kwargs["tools"] = []`` injection when compression is a no-op —
Anthropic Messages rejects empty tool arrays on requests that did not
originally declare tools.
- Move agentic-loop safety guards (fingerprint cycle / max depth) out of
the per-callback try/except so they propagate instead of being swallowed
by the generic exception handler. Extracted _check_agentic_loop_safety.
- Gate generic ``x-<vendor>-session-id`` capture behind the
LITELLM_CAPTURE_VENDOR_SESSION_HEADERS env var (off by default) to
preserve backwards compatibility; explicit x-litellm-* headers are
unaffected.
- Fix monkeypatch target in pre-call-hook test to patch the actual
module-level binding
(litellm.integrations.compression_interception.handler.compress).
- Add regression tests for empty-tools skip and opt-in session capture.

* revert: drop LITELLM_CAPTURE_VENDOR_SESSION_HEADERS flag
Generic x-<vendor>-session-id header capture is a new feature and only
runs *after* the explicit x-litellm-trace-id / x-litellm-session-id
checks, so it does not change behavior for any existing caller that was
already using the LiteLLM headers — no backwards-incompatibility to gate.

* refactor(compress): replace input_type with CallTypes call_type
Drop the bespoke ``CompressionInputType`` literal and use the existing
``litellm.types.utils.CallTypes`` enum instead. ``litellm.compress()``
now takes ``call_type: Union[CallTypes, str]`` (default
``CallTypes.completion``) — no new concept to learn, and the enum is
already the way the rest of the codebase talks about request shapes.
Supported values: ``completion`` / ``acompletion`` (OpenAI chat-completions
shape) and ``anthropic_messages`` (Anthropic structured content blocks).
Updated: compress(), the compression_interception handler, tests, docs,
and the two eval scripts.

Expand the pre-call metadata strip to also remove user_api_key_metadata
and user_api_key_team_metadata. The proxy writes these fields into
data[_metadata_variable_name] with admin-authoritative values, but only
into that one metadata key; the caller's value in the OTHER metadata
key (metadata vs litellm_metadata) would otherwise persist and be
picked up by _get_admin_metadata, letting a caller supply their own
'admin' config to disable guardrails, opt out of global policies, etc.
VERIA-28 (High): Security Policy and Guardrail Bypass via Unsanitized
Request Metadata.
Add regression test at the proxy boundary verifying the strip, and
extend the guardrail test to cover the post-strip admin-config path.
Greptile P2: _get_admin_metadata used 'litellm_metadata or metadata',
meaning a caller sending a non-empty litellm_metadata would shadow
admin config the proxy had injected into data['metadata']. Admin
exemptions would be silently ignored.
Check both keys and prefer whichever contains admin fields. Add
regression test covering the shadowing scenario.
Include user_api_key_team_metadata alongside user_api_key_metadata in
_get_admin_metadata() so team-level guardrail settings are respected.
Key-level settings take precedence over team-level.
Remove turn_off_message_logging from _supported_callback_params so it
cannot be set via request metadata. Admin controls logging globally
or via key/team configuration.
Update tests to verify user-injected guardrail flags are ignored while
admin-configured flags are respected.

* feat(prometheus): add api_provider label to spend metric (#25693)
* feat(prometheus): add api_provider label to spend metric
Add `api_provider` to `litellm_spend_metric` labels so users can
build Grafana dashboards that break down spend by cloud provider
(e.g. bedrock, anthropic, openai, azure, vertex_ai).
The `api_provider` label already exists in UserAPIKeyLabelValues and
is populated from `standard_logging_payload["custom_llm_provider"]`,
but was not included in the spend metric's label list.
* add api_provider to requests metric + add test
Address review feedback:
- Add api_provider to litellm_requests_metric too (same call-site as
spend metric, keeps label sets in sync)
- Add test_api_provider_in_spend_and_requests_metrics following the
existing pattern in test_prometheus_labels.py

* fix(bedrock): skip synthetic tool injection for json_object with no schema (#25740)
When response_format={"type": "json_object"} is sent without a JSON
schema, _create_json_tool_call_for_response_format builds a tool with an
empty schema (properties: {}). The model follows the empty schema and
returns {} instead of the actual JSON the caller asked for.
This patch:
- Skips synthetic json_tool_call injection when no schema is provided.
The model already returns JSON when the prompt asks for it.
- Fixes finish_reason: after _filter_json_mode_tools strips all
synthetic tool calls, finish_reason stays "tool_calls" instead of
"stop". Callers (like the OpenAI SDK) misinterpret this as a pending
tool invocation.
json_schema requests with an explicit schema are unchanged.

* fix(utils): allowed_openai_params must not forward unset params as None
`_apply_openai_param_overrides` iterated `allowed_openai_params` and
unconditionally wrote `optional_params[param] = non_default_params.pop(param, None)`
for each entry. If the caller listed a param name but did not actually
send that param in the request, the pop returned `None` and `None` was
still written to `optional_params`. The openai SDK then rejected it as
a top-level kwarg:
AsyncCompletions.create() got an unexpected keyword argument 'enable_thinking'
Reproducer (from #25697):
allowed_openai_params = ["chat_template_kwargs", "enable_thinking"]
body = {"chat_template_kwargs": {"enable_thinking": False}}
Here `enable_thinking` is only present nested inside
`chat_template_kwargs`, so the helper should forward
`chat_template_kwargs` and leave `enable_thinking` alone. Instead it
wrote `optional_params["enable_thinking"] = None`.
Fix: only forward a param if it was actually present in
`non_default_params`. Behavior is unchanged for the happy path (param
sent → still forwarded), and the explicit `None` leakage is gone.
Adds a regression test exercising the helper in isolation so the test
does not depend on any provider-specific `map_openai_params` plumbing.
Fixes#25697
