fix(bedrock): sanitize batch metadata to prevent Pydantic ValidationError (#28202)
* fix(bedrock): sanitize batch metadata to prevent Pydantic ValidationError

Proxy guardrail hooks (Model Armor, OpenAI Moderations) and internal
processing inject non-string values (dicts, floats) into the request
metadata. When the Bedrock batch handler passes this metadata directly
to LiteLLMBatch (which inherits OpenAI's Batch Pydantic model with
metadata: Dict[str, str]), Pydantic raises a ValidationError. This
causes the router retry loop to re-submit the same Bedrock job
multiple times before ultimately failing.

Add _get_openai_compatible_batch_metadata() that serializes non-string
values to JSON strings via safe_dumps, skips None values and internal
logging keys, ensuring the response object always validates.

* test(bedrock): add tests for batch metadata sanitization

Covers _get_openai_compatible_batch_metadata: string passthrough, dict/float
serialization, None/internal key exclusion, and LiteLLMBatch compatibility.

feat(prometheus): add user_email and user_alias to user budget metrics (#28155)
* feat(prometheus): add user_email and user_alias to user budget metrics

User budget Prometheus gauges now expose human-readable labels alongside
user_id, matching team and API key budget metrics for Grafana filtering.

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

* fix(prometheus): gate user budget email/alias labels behind opt-in flag

Address greptile review: adding labels to existing metrics is a
breaking cardinality change. Gate behind
prometheus_user_budget_label_include_email_alias=True (default: False)
so existing dashboards and recording rules are unaffected.

* fix(ui): omit allowed_routes from key edit save when unchanged (#27553)

* fix(ui): omit allowed_routes from key edit save when unchanged

When a team admin opens Edit Settings on a key with key_type=AI APIs and
saves without changing anything, the UI re-sends the existing allowed_routes
value, which the backend's _check_allowed_routes_caller_permission gate
rejects for non-proxy-admins (LIT-2681).

Strip allowed_routes from the patch in handleSubmit when it deep-equals the
original keyData.allowed_routes. The backend treats absence as "leave alone,"
so no-op saves now succeed for non-admins. Admins explicitly editing the
field still send the new value.

* fix(ui): order-insensitive allowed_routes diff + cover null-original case

Address Greptile review:

- Switch the "is allowed_routes unchanged" check to a Set-based comparison so
  a server-side reorder of the array doesn't register as a user edit and
  re-trigger LIT-2681.
- Add two regression tests: (1) keyData.allowed_routes is null and the form
  is untouched — patch should strip the field; (2) server returned routes in
  a different order than the user originally entered — patch should still
  recognize the value as unchanged.

* chore(ui): strip ticket refs and tighten comments in key edit fix

- Remove internal-tracker references from in-code comments
- Tighten the WHY comment in handleSubmit to two lines
- Drop redundant test-block comments — test names already describe the case

* fix(ui): annotate Set<string> generic in allowed_routes diff to fix tsc

* fix(guardrails): return HTTP 400 instead of 500 for guardrail-blocked requests

GuardrailRaisedException and BlockedPiiEntityError both lacked a
status_code attribute.  When these exceptions reached the proxy
exception handler (getattr(e, 'status_code', 500)), the fallback
defaulted to HTTP 500 — making intentional guardrail blocks
indistinguishable from server errors and causing unnecessary client
retries.

Changes:
- Add status_code=400 (keyword-only) to GuardrailRaisedException
- Add status_code=400 (keyword-only) to BlockedPiiEntityError
- Update _is_guardrail_intervention() to recognize both exceptions
  so downstream loggers record 'guardrail_intervened' instead of
  'guardrail_failed_to_respond'
- Add 6 unit tests for default/custom status codes and getattr pattern
- Strengthen existing blocked-action test with status_code assertion

Fixes #24348

fix(caching): replay openai/responses bridge cache hits as chat streams (#28158)
* fix(caching): replay openai/responses bridge cache hits as chat streams

When chat completions route through openai/responses, cached ModelResponse
payloads under aresponses keys were deserialized as ResponsesAPIResponse
(500) or re-translated as responses events (empty streaming deltas). Deserialize
chat-shaped cache entries as acompletion and bypass the responses stream iterator
for cached CustomStreamWrapper replay.

* test(caching): cover responses bridge cache-hit paths in CI-tracked test suite

The new bridge cache replay logic in caching_handler.py and the
preformatted-stream guard in litellm_responses_transformation/handler.py
were exercised only by tests under tests/local_testing/, which the
responses-caching-types and misc shards do not run. Codecov flagged the
patch as 29.72% covered.

Add equivalent unit tests under tests/test_litellm/ so the responses,
caching, types, and misc shards execute them and ship their coverage
data to Codecov:

- _is_chat_completion_cached_dict happy/sad paths
- aresponses streaming bridge cache hit -> CustomStreamWrapper
- responses non-streaming bridge cache hit -> ModelResponse
- legacy ResponsesAPIResponse stream + non-stream replay
- _is_preformatted_cached_chat_stream true/false
- completion/acompletion early return on cached ModelResponse
- completion/acompletion skip rewrap on preformatted cached stream

* test: bump EOL'd NVIDIA rerank and OpenAI realtime models in CI

The NVIDIA hosted rerank endpoint for nvidia/llama-3_2-nv-rerankqa-1b-v2
reached end-of-life on 2026-05-18 and now returns HTTP 410 Gone, breaking
TestNvidiaNim::test_basic_rerank. Switch to nvidia/nv-rerankqa-mistral-4b-v3,
which is still hosted on the NVIDIA API catalog and is already listed in
model_prices_and_context_window.json.

OpenAI also retired the gpt-4o-realtime-preview-2024-12-17 model used by
test_realtime_guardrails_openai (now returns model_not_found). Switch the
realtime test URL to the GA gpt-realtime alias.

Unrelated to the responses-bridge cache fix in this PR, but committing
here to unblock CI per maintainer guidance.

* test(realtime): switch retired gpt-4o-realtime-preview to gpt-realtime

OpenAI removed gpt-4o-realtime-preview and all its date snapshots on
2026-05-18 (every variant now returns model_not_found), breaking the
live-WebSocket OpenAI realtime tests in CI:

  - test_openai_realtime_direct_call_no_intent
  - test_openai_realtime_direct_call_with_intent
  - TestOpenAIRealtime.test_realtime_connection
  - TestOpenAIRealtime.test_realtime_with_query_params

Point each of those to the current GA alias gpt-realtime (verified live).
Pure unit/mock tests that just assert the string value (e.g. in
test_realtime_query_params_construction and the
test_realtime_query_params_use_normalized_model_name mock) are left
alone since they do not depend on model availability.

Also relax the AI-response assertion in
test_text_message_blocked_by_guardrail_no_ai_response: gpt-realtime
occasionally produces a polite refusal ("I'm sorry, but I can't say
that") when the cancel arrives after the model has already started
generating, which is the expected outcome (no real AI content) but does
not contain the words 'blocked' or 'guardrail'. The primary guardrail
behaviour (guardrail_violation error event + transcript_delta block
message) is still asserted unchanged.

* test(nvidia_nim): mock rerank live API instead of hitting EOL'd endpoint

NVIDIA reached end-of-life for the hosted nvidia/llama-3.2-nv-rerankqa-1b-v2
rerank API on 2026-05-18 (returns HTTP 410 Gone), and the proposed
replacement nv-rerankqa-mistral-4b-v3 returns HTTP 404 for the CI account,
breaking TestNvidiaNim::test_basic_rerank.

Override test_basic_rerank to mock the HTTP transport (same pattern as
test_nvidia_nim_rerank_ranking_endpoint above) so the request/response
transformation and cost calculation stay covered without depending on
NVIDIA's hosted catalog rotation. The model identifier reverts to the
original llama-3.2-nv-rerankqa-1b-v2 since the request never leaves
the test process.

fix(proxy): gate team allowed_passthrough_routes to proxy admins (#28097)
* fix(proxy): gate team allowed_passthrough_routes to proxy admins

allowed_passthrough_routes short-circuits the role-based route gate, so
the keys endpoints already restrict it to proxy admins. The team writers
(/team/new, /team/update) had no equivalent check, letting an org admin
(a non-proxy-admin who clears the route gate and _verify_team_access)
self-grant pass-through routes on their team. Lift the keys check into a
shared helper and apply it to both team endpoints.

Resolves LIT-3019

* docs(proxy): note view-only admins are intentionally excluded from passthrough gate

Clarifies the proxy-admin guard per review feedback; no behavior change.

fix(mcp-oauth): PROXY_BASE_URL escape hatch + diagnostic logging for {"detail":"invalid_request"} (#28086)
* fix(mcp-oauth): add PROXY_BASE_URL escape hatch + diagnostic logging for invalid_request

Customers hitting "{"detail":"invalid_request"}" on the MCP /authorize
endpoint had no way to recover when their ingress mangles X-Forwarded-*
headers (the same-origin check in validate_trusted_redirect_uri compares
the browser-supplied redirect_uri against get_request_base_url, which is
reconstructed from those headers).

Two contained changes:

  1. get_request_base_url now honours PROXY_BASE_URL as the canonical
     public origin when set, bypassing the X-Forwarded-* trust gate
     entirely. Operators who know their public URL can set it once
     instead of debugging ingress header rewrites.

  2. The rejection path in validate_trusted_redirect_uri emits a WARN
     log carrying the redirect_uri, computed proxy base, and the
     X-Forwarded-* / Host headers seen. A bare 400 was undiagnosable;
     this turns it into a one-line root-cause.

* test(mcp-oauth): capture warnings from correct logger ("LiteLLM")

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp-oauth): reject malformed PROXY_BASE_URL with one-shot diagnostic

A scheme-less PROXY_BASE_URL (e.g. "litellm.example.com" instead of
"https://litellm.example.com") would sail through urlparse with empty
scheme + netloc, silently breaking every same-origin compare in
validate_trusted_redirect_uri and leaving the operator staring at the
same opaque 400 the env var was meant to fix.

Validate it once at read time: only honour values that parse as
http(s) URLs with a non-empty netloc; otherwise log a one-shot WARN
naming the bad value and fall through to the request-derived origin
so the proxy still serves traffic.

* fix(mcp/oauth): normalize PROXY_BASE_URL to strip query/fragment

Match the X-Forwarded-* path's normalization so a configured
PROXY_BASE_URL containing a query string or fragment does not break
downstream f-string concatenation like f"{base_url}/callback".

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* refactor(mcp-oauth): drop non-essential comments from PROXY_BASE_URL changes

Strip narrative comments and verbose docstrings added in this PR; the
code is intuitive enough on its own and the log messages already carry
their own diagnostic context. Pre-existing comments are left untouched.

fix(proxy): sort BYOK models by their displayed name in /v2/model/info (#28079)
* fix(proxy): sort BYOK models by team_public_model_name in /v2/model/info

Team BYOK rows persist an internal `model_name` like
`model_name_{team_id}_{uuid}` and expose the user-facing name via
`model_info.team_public_model_name`. The UI's `getDisplayModelName`
and the search filter already fall back to that field, but
`_sort_models` was keying off the raw `model_name` — so BYOK rows
ranked by their opaque IDs and clumped at the end of the alphabetized
list instead of interleaving with non-BYOK rows.

Match the UI/search behavior: prefer `team_public_model_name` when
present, fall back to `model_name` otherwise.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(proxy): case-insensitive DB-side search for BYOK models

`_apply_search_filter_to_models` used Prisma's JSON path
`string_contains` to match the BYOK `team_public_model_name` field, but
that operator is case-sensitive in Postgres (no `mode: insensitive`
flag like column-level string filters have). So a search for "claude"
missed a stored "Claude Sonnet" via the DB branch even though the
router-side path matched it case-insensitively.

Widen the JSON branch to "row has a team_public_model_name set" and
filter case-insensitively in Python so DB-only BYOK rows match the
same terms users see in the UI. This also drops the now-unused
DB-level page-size optimization and `sort_by` knob — the in-Python
filter is the source of truth for `db_models_total_count` now.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(proxy): scope BYOK search results to caller's accessible teams

`_apply_search_filter_to_models` was widened to fetch every row with a
`team_public_model_name` set so case-insensitive search could match
mixed-case stored names. `/v2/model/info` is reachable by non-admin
keys though, and the helper ran before `include_team_models` / `teamId`
filtering — so a non-admin caller could search a common substring like
"claude" and see BYOK rows belonging to teams they're not a member of.

Resolve the caller's team membership once (admin → no scoping, else
their `user_row.teams`) and drop BYOK rows (those with
`model_info.team_id` set) outside that scope on both the router-side
matches and the over-broad DB query, before display-name matching.
Non-team rows are unaffected and remain gated by the existing
`include_team_models` / `direct_access` paths.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(proxy): search by team_public_model_name and scope teamId queries

- /v2/model/info search now matches both `model_name` and
  `model_info.team_public_model_name`, so team BYOK rows (which persist
  an internal `model_name_{team_id}_{uuid}`) are findable by the public
  name shown in the UI. DB query OR-includes a JSON-path match on
  `team_public_model_name` for rows that exist only in the DB.
- `_filter_models_by_team_id` no longer short-circuits on the viewer's
  `direct_access` flag — that describes the admin viewer's own
  permissions and would leak every public model into a team-scoped view.
  Models are kept only when they belong to the team (own BYOK, in
  access_via_team_ids, or reachable via team.models / access groups).
- Added `_authorize_team_id_query`: the untrusted `teamId` query
  parameter now requires the caller to be a proxy admin or a member of
  the requested team, otherwise returns 403. Without this, any
  authenticated user could enumerate another team's BYOK metadata by
  guessing the team id.
- `_get_caller_byok_team_scope` now treats `PROXY_ADMIN_VIEW_ONLY` the
  same as `PROXY_ADMIN` (both are admin roles); previously VIEW_ONLY
  admins fell through to a user-id team lookup and saw only their own
  teams' BYOK rows.

* fix(proxy): bound BYOK search DB fetch in /v2/model/info

Previously the DB-side search OR'd a JSON-path predicate
`{model_info: {path: [team_public_model_name], string_contains: ""}}`
to compensate for Prisma's case-sensitive JSON `string_contains` on
Postgres. That predicate matches every row that has any
`team_public_model_name` set, so any authenticated caller could force a
full BYOK-table read with `/v2/model/info?search=x` regardless of page
size.

Drop the JSON-path branch. The DB query now does a bounded
`model_name contains <search>` lookup. BYOK rows that are loaded into
the router are still searchable by their `team_public_model_name` via
the router-side filter; only the rare edge case of a BYOK row that
exists only in the DB (router sync failed) loses display-name search,
which is an acceptable trade-off given the DoS surface.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(proxy): bound DB find_many in /v2/model/info search

The previous bounding patch dropped the page-aware `take=N` on
`find_many`, so a broad `?search=model` would load and decrypt every
matching DB row on each request even though the response only returns
one page.

Restore bounded fetches in `_apply_search_filter_to_models`:

* Unsorted searches use `take = max(0, page * size - router_count)`,
  i.e. exactly one page worth of remaining DB rows.
* Sorted searches need ordering across the full match set, so they cap
  at `_SORTED_SEARCH_DB_FETCH_CAP = 500` instead of fetching everything.
* Total count comes from a cheap `count(...)` query so pagination stays
  accurate without materializing every row.

Wired `page`, `size`, and `sortBy` through from the endpoint and added
a regression test covering both `take` values.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor(proxy): extract DB-fetch helper to satisfy PLR0915

_apply_search_filter_to_models tripped Ruff's "too many statements"
(51 > 50) after the bounded-fetch fix. Move the DB-side block into
`_fetch_db_models_for_search`, which keeps the same behavior:

* Bounded `take` via page math (unsorted) or `_SORTED_SEARCH_DB_FETCH_CAP`
  (sorted)
* Cheap `count(...)` for accurate pagination totals
* Caller-team scope applied to fetched rows before decrypt

Pure refactor; no behavior change. All 8 BYOK/team tests still pass.

feat(otel): set http.response.status_code on the success SERVER span (#28090)
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.

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.

feat: add componentized proxy deployment with gateway, backend, ui, and migrations (#27557)
Split the monolithic LiteLLM proxy into independently scalable Kubernetes components to allow separate horizontal scaling of the LLM data plane and management API surfaces

- Add DatabaseURLSettings pydantic-settings model that assembles DATABASE_URL (and optional DATABASE_URL_READ_REPLICA) from discrete DATABASE_* env vars before Prisma initializes, supporting both IAM token auth (minting short-lived RDS tokens) and password auth; replaces the CLI-only path that componentized entrypoints bypass
- Add gateway component (port 4000) that trims the proxy route table to the LLM data-plane surface (chat, embeddings, completions, audio, realtime, provider passthroughs, health/metrics) via an allowlist applied inside the lifespan context so plugin-registered routes are captured
- Add backend component (port 4001) that exposes the management/admin surface (keys, users, teams, orgs, spend analytics, model management, SSO, audit logs) with a complementary allowlist
- Add ui component — Next.js static export served by nginx (port 3000) with RSC payload routing, asset prefix aliasing, and SPA fallback for dashboard routes
- Add migrations component with dedicated Dockerfile that runs prisma migrate deploy via a Helm pre-install/pre-upgrade Job, eliminating per-pod schema contention on the Prisma advisory lock
- Add Helm chart (helm/litellm) with separate Deployments, Services, HPAs, and ConfigMap for each component; shared _helpers.tpl emits DATABASE_*, IAM_TOKEN_DB_AUTH, REDIS_*, and DISABLE_SCHEMA_UPDATE env vars from chart values; ingress template routes traffic to the correct component by path prefix
- Add comprehensive tests for DatabaseURLSettings covering IAM auth, password auth, read replica fallbacks, operator-pinned URL preservation, and percent-encoding; add coverage test asserting gateway + backend allowlist union equals the full proxy route set
- Add pydantic-settings>=2.14.1 as a proxy extra dependency and update liccheck allowlist

test(interactions): validate response fields against Interaction schema
Google restructured the live spec at ai.google.dev/static/api/
interactions.openapi.json: the output-only fields (notably the
`steps` array, formerly `outputs`) moved off the request schema
`CreateModelInteractionParams` onto a dedicated `Interaction`
response schema. The response-side tests still read from the
request schema, so `test_interaction_response_fields` failed with
"Output field 'steps' not in spec".

Point `test_interaction_response_fields` and `test_status_enum_values`
at the `Interaction` schema (the semantic response object; all output
fields incl. `steps` present there). Request-side tests keep using
`CreateModelInteractionParams` (all request fields verified still
present). 13/13 pass against the current live spec.

feat: add OTEL GenAI latest-experimental semantic convention support (#27418)
- 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

test(proxy): isolate run_server CLI tests from prisma DB-setup path
test_keepalive_timeout_flag and test_timeout_worker_healthcheck_flag
were the only run_server tests in test_proxy_cli.py that neither
stripped DATABASE_URL/DIRECT_URL nor mocked the prisma DB path. When a
DATABASE_URL is present (CI/env leak), run_server --local enters the DB
block and blocks in the un-timeout'd subprocess.run(["prisma"]) at
proxy_cli.py:987 plus the ProxyExtrasDBManager migrate-deploy retry
loops, ~370s per test on the CI runner. --dist=loadscope pins both to
one xdist worker, so the proxy-infra job appears stuck at 99% and hits
the 20-min timeout.

Apply the same isolation every other run_server test in this file
already uses: mock PrismaManager.setup_database +
should_update_prisma_schema and strip DATABASE_URL/DIRECT_URL. Full
module drops from 31.7s to 2.9s locally; both tests fall off the slow
list.

test(proxy): add endpoint-level regression for /config/update double-encryption
Adds test_update_config_env_var_round_trip_not_double_encrypted, which
drives the real /config/update handler: first write plaintext, then
re-POST the stored ciphertext (the Admin UI round-trip) and assert the
value is not stacked with a second encryption layer and untouched keys
stay byte-identical. Verified to fail against the pre-fix handler and
pass after. Also tightens the unit test to exactly three ciphertext
re-feeds.

A single decrypt-then-encrypt chokepoint (_encrypt_env_variables_for_db)
now backs both update_config and save_config. Re-submitting a value the
Admin UI read back from /get/config/callbacks as ciphertext no longer
stacks a second encryption layer, which previously decrypted to garbage
and silently broke the callback. The chokepoint decrypts with the pure
_decrypt_db_variables (no os.environ mutation on the write path) and
encrypts exactly once; update_config merges only the sent keys so
untouched env vars keep their stored ciphertext byte-for-byte.

* Sanitize empty text content blocks on /v1/messages (#27832)

Squash-merged by litellm-agent from Cyberfilo's PR.

* fix(bedrock-mantle): use /anthropic/v1/messages path for Mantle endpoint

The bedrock-mantle gateway (Claude Mythos Preview) serves the Anthropic
Messages API at /anthropic/v1/messages; /v1/messages returns 404 Not
Found. Both AmazonMantleConfig (chat/completions caller route) and
AmazonMantleMessagesConfig (anthropic-messages caller route) hardcoded
the wrong path, so every Mantle request 404'd before reaching the model.

Per the Anthropic docs: "[Claude in Amazon Bedrock] uses the Messages
API at /anthropic/v1/messages with SSE streaming."
https://platform.claude.com/docs/en/api/claude-on-amazon-bedrock

Confirmed independently against the live endpoint:
  /v1/chat/completions      -> 200 OK
  /v1/messages              -> 404 Not Found  (what litellm used)
  /anthropic/v1/messages    -> 200 OK         (Claude only)

Adds a regression test asserting both Mantle configs build the
/anthropic/v1/messages path, and updates the existing assertions that
encoded the wrong path.

feat: add weighted-routing failover (#27980)
* Feat: Add Weighted-Routing Failover

* test(router): cover weighted failover helper functions

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

* fix(router): align weighted failover deployment list type with mypy

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

* fix(router): address greptile review on weighted failover

- Narrow exception swallowing in `_maybe_run_weighted_failover` to
  `openai.APIError` so model failures defer to the regular fallback
  while programming bugs (AttributeError/KeyError/TypeError) surface.
- Note async-only limitation of `enable_weighted_failover` in the
  Router constructor docstring.
- Make the weighted distribution test less flaky (1000 iterations,
  looser bound) and make the non-simple-shuffle test deterministic by
  failing both deployments instead of relying on the latency strategy's
  first pick.

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

* fix(router): ensure weighted failover metadata persists in kwargs

The previous `kwargs.setdefault(metadata_variable_name, {}) or {}` returned
a brand-new dict whenever the existing metadata was falsy (empty dict or
None), so writes to `_failover_excluded_ids` never made it back into
`kwargs`. Multi-hop weighted failover then re-selected previously failed
deployments and exhausted `max_fallbacks` prematurely.

Explicitly assign a fresh dict into kwargs when metadata is missing so
mutations are visible to subsequent failover hops.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* test(router): regression for weighted failover metadata persistence

Asserts kwargs["metadata"]["_failover_excluded_ids"] is populated after
_maybe_run_weighted_failover, proving the metadata dict written by the
helper is the same object that lives in kwargs (no disconnected copy).
Pairs with the prior fix that replaced `setdefault(..., {}) or {}` with
an explicit get/assign so writes survive across hops.

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

* fix(router): harden weighted failover error/state handling

- Catch RouterRateLimitError (ValueError) alongside openai.APIError in
  _maybe_run_weighted_failover so an exhausted intra-group retry falls
  through to the regular cross-group fallback path instead of bubbling
  out and bypassing configured fallbacks.
- Stop mutating the shared input_kwargs dict; build a local copy with
  the weighted-failover keys so the entry (with _excluded_deployment_ids)
  cannot leak into later fallback paths reading the same dict.
- _get_excluded_filtered_deployments now returns an empty list when the
  exclusion filter removes every healthy deployment, instead of falling
  back to the original list. The original-list behavior risked re-picking
  the just-failed deployment; callers already handle the empty case by
  raising their no-deployments error, which weighted failover now catches
  and converts into a normal cross-group fallback.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(router): fall through to rpm/tpm when total weight is zero

When the weight metric's total is zero (e.g. after weighted-failover
exclusion leaves only zero-weight backups), continue to the next metric
(rpm/tpm) instead of returning a uniform random pick immediately. This
lets rpm/tpm still drive routing when present, and only falls back to
the uniform random pick at the end if no metric provides a positive
total weight.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(router): skip weighted failover when remaining deployments are all in cooldown

_maybe_run_weighted_failover was computing 'remaining' from all_deployments
(every deployment in the model group, including those in cooldown). This meant
that when all non-excluded deployments were in cooldown the method still invoked
run_async_fallback unnecessarily, which propagated into async_get_healthy_deployments,
found no eligible deployments, and raised RouterRateLimitError — only safely
caught thanks to the earlier exception-broadening fix.

The fix: before computing 'remaining', fetch the current cooldown set via
_async_get_cooldown_deployments and subtract it from all_ids. This allows
_maybe_run_weighted_failover to return None immediately (skipping the
run_async_fallback call entirely) when every non-failed deployment is in cooldown,
letting the caller fall through to the correct cross-group fallback path without
the wasteful extra round-trip.

Tests added:
- unit: _maybe_run_weighted_failover returns None without calling run_async_fallback
  when all remaining deployments are in cooldown
- unit: _maybe_run_weighted_failover still calls run_async_fallback when at least
  one healthy (non-cooldown) deployment is available
- integration: end-to-end fallthrough to cross-group fallback when remaining
  deployments are in cooldown

fix(vertex-ai): fix zero cost/usage on completed Vertex AI batch jobs (#27912)
* fix(vertex-ai): fix zero cost/usage on completed Vertex AI batch jobs

Vertex batch jobs recorded 0 spend and 0 tokens after PR #25627 added
automatic transformation of GCS predictions.jsonl to OpenAI format.

Two bugs fixed:

1. batch_utils.py: the Vertex-specific cost/usage reader
   (calculate_vertex_ai_batch_cost_and_usage) was always invoked and
   reads raw usageMetadata fields that no longer exist in the
   OpenAI-shaped output. Now the reader is only used when
   disable_vertex_batch_output_transformation=True; otherwise the
   generic path handles the already-transformed OpenAI-shaped content.

2. cost_calculator.py: batch_cost_calculator skipped the global
   litellm.get_model_info() lookup when a model_info dict was passed
   in, even when that dict had no pricing fields (e.g. deployment
   metadata with only id/db_model). It now falls back to the global
   pricing table when the provided model_info has no pricing data.

CheckBatchCost bypasses async_post_call_success_hook, causing raw provider
output_file_ids to be persisted in LiteLLM_ManagedObjectTable. This fix converts
output_file_id and error_file_id to managed base64 IDs before the DB write.

  an orphaned managed ID into file_object when the store call fails.
- Populate team_id on the minimal UserAPIKeyAuth from job.team_id so the

Emit native web_search_tool_result blocks for Anthropic clients (Claude Desktop / Cowork citations) (#27886)
* 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(rate-limit): stop v3 limiter from leaking internal stash to provider body (#27913)
* fix(rate-limit): stop v3 limiter from leaking internal stash to provider body

PR #27001 (atomic TPM rate limit) introduced a reservation flow that
writes four LiteLLM-internal keys onto the request data dict:

  _litellm_rate_limit_descriptors
  _litellm_tpm_reserved_tokens
  _litellm_tpm_reserved_model
  _litellm_tpm_reserved_scopes
  _litellm_tpm_reservation_released

These keys are forwarded as request body params to the upstream provider,
which rejects them as unknown fields:

  OpenAI    -> 400 'Unknown parameter: _litellm_rate_limit_descriptors'
              (mapped by litellm to RateLimitError / 429, hiding the bug
               behind a misleading 'throttling_error' code)
  Anthropic -> 400 '_litellm_rate_limit_descriptors: Extra inputs are
               not permitted'

Net effect: every chat completion against any real provider fails the
moment a virtual key has any tpm_limit / rpm_limit set — i.e. v3-enforced
key-level TPM/RPM limits are broken end-to-end. The v3 RPM/TPM check
itself still runs (raises 429 on over-limit), but the success path
poisons the upstream body.

Reproduced on litellm_internal_staging HEAD (410ce761dc) against
gpt-4o-mini and claude-haiku-4-5 with a 1-RPM/1-TPM key — first request
fails with the provider's unknown-field error.

Fix: the stash is metadata only.

  - Add RATE_LIMIT_DESCRIPTORS_KEY constant and a _LITELLM_STASH_KEYS
    registry so we have a single source of truth for stash keys.
  - New helper _stash_value_in_metadata_channels writes to
    data['metadata'] / data['litellm_metadata'] without touching the
    top level.
  - _stash_reservation_in_data and the descriptor stash now route
    through that helper. _mark_reservation_released stops writing
    top-level.
  - _lookup_stashed_value also checks kwargs['metadata'] /
    kwargs['litellm_metadata'] (raw request_data shape) in addition to
    kwargs['litellm_params']['metadata'] (completion kwargs shape).
  - async_post_call_failure_hook now reads descriptors via the unified
    metadata lookup instead of request_data.get(top-level).
  - Defense in depth: async_pre_call_hook strips any stash key that
    somehow surfaced at the top level (stale cache, future refactor,
    test fixture) before returning.

Tests:
  - New regression test asserts no _litellm_* stash key is present at
    the top level of data after async_pre_call_hook, and that the
    metadata channel still carries the reservation + descriptors so
    success / failure reconciliation works.
  - Existing test_tpm_concurrent.py tests that asserted top-level
    presence are updated to read from data['metadata'] — the location
    is an implementation detail; the spec is that post-call callbacks
    can resolve the stash.

Verified end-to-end against OpenAI gpt-4o-mini and Anthropic
claude-haiku-4-5 via /v1/chat/completions on a low-rpm key:

  - With limits not exceeded: HTTP 200, valid completion response,
    no leaked fields in body.
  - With RPM exceeded: HTTP 429 from v3 enforcement
    ('Rate limit exceeded ... Limit type: requests').
  - With TPM exceeded: HTTP 429 from v3 enforcement
    ('Rate limit exceeded ... Limit type: tokens').

Full v3 hook test suite passes (171 tests).

* chore(rate-limit): use RATE_LIMIT_DESCRIPTORS_KEY constant in test, trim noisy comments

Address greptile P2: test fixture now uses the imported constant.
Drop comments that re-explain what well-named identifiers already convey.

* fix(rate-limit): reject caller-supplied stash values to prevent TPM-refund abuse

Strip _LITELLM_STASH_KEYS from data top-level and both metadata channels at
the start of async_pre_call_hook. Without this, an authenticated caller can
inject _litellm_rate_limit_descriptors plus _litellm_tpm_reserved_tokens in
body metadata, trigger a proxy-side rejection, and cause
async_post_call_failure_hook to refund TPM counters against attacker-named
scopes (e.g. another tenant's api_key).

perf: eliminate per-request callback scanning on proxy hot path (#27858)
- Introduce `_CallbackCapabilities` dataclass and `ProxyLogging._callback_capabilities()` static method that inspects `litellm.callbacks` once and caches capability flags keyed on (list length, member ids); invalidates automatically when the callback list mutates without per-request iteration overhead
- Replace O(n) `litellm.callbacks` walks in `async_pre_call_hook`, `during_call_hook`, `async_post_call_streaming_iterator_hook`, `async_post_call_streaming_hook`, and `post_call_response_headers_hook` with fast-path exits when no relevant callbacks are registered
- Add `needs_iterator_wrap()` and `needs_per_chunk_streaming_hook()` instance methods to decouple iterator-level wrapping from per-chunk hook execution; avoids `get_response_string` materialization per chunk when no guardrail or chunk-hook callback is active
- Introduce `_fast_serialize_simple_model_response_stream()` using `orjson` for common single-choice text streaming chunks, bypassing the full Pydantic serializer; falls back to `model_dump_json` for tool calls, logprobs, usage, and provider-specific fields
- Add early-return in `_restamp_streaming_chunk_model` when downstream model already matches the requested model, avoiding unnecessary string comparisons on every chunk
- Fix stale zero-cost cache bug in `_is_model_cost_zero`: move the per-router `_zero_cost_cache` dict onto the `Router` instance and clear it in `_invalidate_model_group_info_cache` so in-place pricing updates via `upsert_deployment` immediately resume budget enforcement
- Add `scripts/benchmark_chat_completions_perf.py`: standalone async benchmarking tool with a mock OpenAI provider, LiteLLM proxy process management, non-streaming RPS, streaming TTFT, and full-stream latency measurements with repeat/median run support
- Add comprehensive unit tests covering capability detection, cache invalidation, fast-path correctness, zero-cost cache regression, and the no-callback streaming fast path

feat(lasso): add tool-calling support to LassoGuardrail (#27648)
* feat(lasso): extend LassoGuardrail to support tool calling (RND-5748)

* fix(lasso): PR review followups for tool-calling guardrail (RND-5748)

* fix(lasso): handle object-style tool_calls in _update_tool_calls_from_masked (RND-5748)

* fix(lasso): use model role for tool_use blocks (RND-5748)

* test(lasso): add round-trip tests for message transformation (RND-5748)

* fix(lasso): remove unused imports, handle Responses-API input masking, flatten multimodal content (RND-5748)

* fix(lasso): inspect Responses-API input field (RND-5748)

* fix(lasso): guard text-cursor remap against Lasso count mismatch (RND-5748)

* fix(lasso): flatten list content in tool_result.content (RND-5748)

* fix(lasso): remap multimodal list content during masking (RND-5748)

Bug: _map_masked_messages_back counted list-content messages in
original_text_count but the remap loop only handled isinstance(str).
The positional text_cursor never advanced for list messages, causing
all subsequent masked texts to be written onto the wrong messages.

Fix: added elif isinstance(content, list) branch that replaces the
list with the masked text string and advances the cursor — mirrors
the existing string-content branch. Also handles the assistant +
tool_calls combo for list-content messages.

Test: test_map_masked_messages_back_list_content verifies a user
message with [text + image_url] followed by an assistant message
gets correct masked content on both (cursor stays aligned).

* refactor(lasso): extract _get_field and _extract_tool_call_fields helpers (RND-5748)

The dict-vs-object access pattern (x.get('y') if isinstance(x, dict)
else getattr(x, 'y', None)) was duplicated 14 times across 5 methods.

_get_field(obj, field) — single-point dict/Pydantic field access.
_extract_tool_call_fields(call) — returns (call_id, name, parsed_input)
with JSON argument parsing, replacing ~30 duplicate lines in both
async_post_call_success_hook and _expand_messages_for_classification.

Also simplified _update_tool_calls_from_masked, _prepare_payload tool
mapping, and _apply_masking_to_model_response call_id extraction.

Net ~60 lines removed. No behavior change — all 32 tests pass.

* fix(lasso): add count guard to _apply_masking_to_model_response (RND-5748)

_apply_masking_to_model_response used a bare text_cursor without
verifying 1:1 correspondence between text-bearing choices and masked
text entries. If Lasso returned a different number of text messages
than choices with content, masked text would be applied to the wrong
choice or silently skip choices.

Added the same count-mismatch guard pattern already used in
_map_masked_messages_back: count original text-bearing choices,
compare to masked_text length, skip text remap on mismatch with a
warning log. Tool_call masking via id-based lookup is unaffected.

Tests:
- test_apply_masking_to_model_response_multiple_choices: verifies
  correct per-choice masked text with 2 choices
- test_apply_masking_to_model_response_count_mismatch: verifies
  content is left unchanged when counts disagree

* fix(lasso): close two guardrail-bypass paths flagged in review (RND-5748)

* tool-call args: when function.arguments is malformed JSON or parses
  to a non-object, preserve the raw string as {"arguments": <raw>} so
  Lasso still inspects it instead of receiving input=None. Covers both
  pre-call and post-call extraction (shared helper). Also resolves the
  CodeQL empty-except warning since the except body now assigns parsed=None.
* Responses-API input: when a request carries both "messages" and
  "input", inspect both. Previously a benign messages array let the
  guardrail skip data["input"] entirely. The masking write-back is
  split via a count boundary so masked messages flow back to
  data["messages"] and masked input flows back to data["input"]
  without cross-contamination.

Tests: malformed/non-object args round-trip, dual-field classification,
dual-field masking write-back split.

* chore(lasso): black formatting + comment on expand skip branch (RND-5748)

* black: wrap two long expressions in lasso.py and reformat dict
  literals in test_lasso.py to satisfy CI lint.
* add a short comment in _expand_messages_for_classification
  explaining why empty string and None content are intentionally
  skipped (None is the OpenAI shape for a pure tool-call turn).

* fix(lasso): satisfy mypy in _handle_masking, _update_tool_calls_from_masked, _apply_masking_to_model_response (RND-5748)

* Narrow `response.get("messages")` into a local before slicing so
  mypy doesn't see `Optional[List[Dict[str, str]]]` as non-indexable.
* Rename the two write-side `func` bindings in
  `_update_tool_calls_from_masked` to `func_dict` / `func_obj` so
  mypy doesn't unify the dict and Any|None branches.
* Rename the inner loop variable in `_apply_masking_to_model_response`
  from `msg` to `masked_msg` to avoid clashing with the
  `msg = choice.message` rebinding below.

No behavior change; resolves the 7 mypy errors from the CI lint job.

fix: tighten budget field validation and authorization checks (#27897)
* fix: block NaN/Inf budget bypass and add missing non-admin guards

Addresses three security issues:

GHSA-wvg4-6222-3q4r: /user/update exposes max_budget, soft_budget, spend
to self-editing non-admin users with no server-side guard. Non-admin callers
now receive HTTP 403 if any of those fields appear in the update payload.

GHSA-q775-qw9r-2r4g: _enforce_upperbound_key_params returned early (no-op)
when upperbound_key_generate_params was absent from config, letting any
authenticated user generate a key with unlimited max_budget. Fix adds a
delegated-authority ceiling in _common_key_generation_helper: non-admins
cannot grant a key more budget than their own key carries.

GHSA-2rv4-xv66-fpjg: float('nan') passes every `value < 0` guard because
nan < 0 is False in Python, and spend >= nan is always False, permanently
disabling budget enforcement for any entity carrying a NaN max_budget.
All write-time budget guards now use `not math.isfinite(v) or v < 0`.
_enforce_upperbound_key_params validates finiteness unconditionally (before
the early-return). All spend-enforcement comparisons in auth_checks.py are
now guarded with math.isfinite(max_budget) as defense-in-depth.

Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

* fix: close budget ceiling bypass for callers with no max_budget (GHSA-q775)

Non-admin callers whose API key has no explicit max_budget (None) could
bypass the delegated-authority ceiling and create keys with arbitrary
budgets. Now blocks budget assignment when caller has no budget configured.
Also removes redundant inline import of LitellmUserRoles.

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

* fix: only apply budget ceiling to explicitly requested max_budget

Capture the caller-supplied max_budget before _enforce_upperbound_key_params
can fill it with a default, so auto-filled defaults don't trigger the
ceiling guard for non-admin users with no budget on their own key.

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

* fix: capture requested max_budget before any defaults are applied

Move _requested_max_budget capture before both default_key_generate_params
and upperbound_key_generate_params mutations, so auto-filled values don't
trigger the ceiling check for non-admin users.

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

* fix: allow unlimited-budget callers to delegate any budget

Callers with max_budget=None (unlimited) can legitimately create
budget-capped keys. Only block when caller has an explicit budget
and the requested budget exceeds it.

Provider validation errors (e.g. OpenAI RateLimitError carrying 178
pydantic errors each with their own 'input': [...]) were stored verbatim
in LiteLLM_SpendLogs.metadata.error_information.error_message via
str(original_exception), producing rows >12 MB.

Sanitize before metadata is serialized:
- redact 'input'/'messages' values in both error_message and traceback
  when store_prompts_in_spend_logs is False (back-door leak paths)
- always apply the MAX_STRING_LENGTH_PROMPT_IN_DB size cap to
  error_message and traceback (DB-storage safeguard)

Value scanning uses a parser-based balanced-bracket walk that respects
string quoting, so multi-modal payloads ('messages': [{'content': [...]}])
and user text containing literal brackets ("secret[123") are handled
correctly instead of leaking past a depth-1 regex.

Scoped to the spend-log path so OTEL/Datadog/etc. callbacks still
receive the untruncated error per LITELLM_TRUNCATION_DB_SAFEGUARD_NOTE.

fix: harden /key/update authorization checks (#27878)
* fix: patch Host-header auth bypass in get_request_route

Starlette reconstructs request.url from the Host header. A malformed
Host like `localhost/?x=1` causes Starlette to build the full URL as
`http://localhost/?x=1/health`, which url-parses to path="/". Since "/"
is in LiteLLMRoutes.public_routes, all protected routes became reachable
without authentication.

Fix: read scope["path"] (set by uvicorn from the HTTP request line,
not derivable from headers) instead of request.url.path. Sub-path
deployments are handled via scope["app_root_path"] / scope["root_path"],
mirroring Starlette's own base_url construction logic.

Affected variants confirmed fixed:
  Host: localhost/?x=1
  Host: localhost:4000/?x=1

* fix: block credential fields in RAG ingest vector_store options

Credential fields (vertex_credentials, aws_access_key_id, api_key, etc.)
in ingest_options.vector_store are now rejected at the API boundary with
a 400 error. Credentials must be configured server-side.

Previously any authenticated user could supply a vertex_credentials dict
with type=external_account pointing credential_source.file at an
arbitrary path (e.g. /proc/1/environ) and token_url at an
attacker-controlled server. google-auth's identity_pool.Credentials

* fix: block /key/update self-escalation by assigned users

Non-admin users who were assigned a key (created_by != caller) could
update any non-budget field — models, rpm_limit, guardrails, etc. —
without admin authorization, allowing privilege self-escalation.

Gate: only the key creator (created_by == caller) may edit their own
key without admin check; budget changes always require admin regardless
of creator status. All other callers must pass _check_key_admin_access.

* fix: block user-controlled api_base in RAG ingest vector_store options

Any authenticated internal_user could POST arbitrary provider config

- Gate the endpoint on PROXY_ADMIN role (403 for all other roles)
- Call is_request_body_safe() to reject banned params even for admins

provider credentials to an attacker-controlled endpoint during SDK

* fix: block SSRF via api_base in /prompts/test dotprompt YAML frontmatter

Any frontmatter key not in ["model","input","output"] flowed into
optional_params and was merged into the LLM call data dict, bypassing
is_request_body_safe. An attacker with any bearer key could set
api_base in YAML to redirect the outbound LLM request — including the
provider API key — to an attacker-controlled host.

Fix: call is_request_body_safe on the constructed data dict after
optional_params are merged, before invoking ProxyBaseLLMRequestProcessing.
ValueError from the banned-param check is surfaced as HTTP 400.

* fix: coerce nested config strings before banned-param check

_NESTED_CONFIG_KEYS descent used isinstance(nested, dict) which silently
skipped litellm_embedding_config when delivered as a JSON string via
multipart/form-data. Banned params (api_base, aws_sts_endpoint, etc.)
nested inside the stringified value were invisible to is_request_body_safe.

_NESTED_METADATA_KEYS already used _coerce_metadata_to_dict which parses
JSON strings before checking. Apply the same coercion to _NESTED_CONFIG_KEYS.

* fix: replace substring match with prefix match in is_llm_api_route

mapped_pass_through_routes used `_llm_passthrough_route in route` (substring)
so any admin-only path whose URL contained a provider name (openai, anthropic,
azure, bedrock, etc.) was misclassified as an LLM API route and bypassed the
admin gate in non_proxy_admin_allowed_routes_check.

Confirmed live: non-admin key could GET /credentials/by_name/openai (read
masked provider API key) and DELETE /credentials/openai (delete credential).

Fix: use exact match or startswith(prefix + "/") — the same pattern used
everywhere else in RouteChecks — so only routes that actually start with a
passthrough prefix are allowed through.

* fix: stabilize PR #27878 test failures

- key_management_endpoints: extend can_skip_admin_check to team keys so
  team members with /key/update permission can update non-budget fields.
  can_team_member_execute_key_management_endpoint already validates team
  membership + permission and raises if unauthorized; reaching the admin
  check on a team key means the caller was authorized.

- test: set created_by on mock key in
  test_update_key_non_budget_fields_allowed_for_internal_user so
  caller_is_creator resolves correctly (MagicMock default ≠ user_id).

- auth_utils.get_request_route: guard against non-dict request.scope
  (e.g. MagicMock in unit tests) to prevent a MagicMock leaking into
  UserAPIKeyAuth.request_route and failing Pydantic validation.

- ci: assign test_multipart_bypass_repro.py to the proxy-runtime shard
  in test-unit-proxy-db.yml to satisfy the shard-coverage check.

* fix: guard bare-/ root_path strip + make total_spend migration idempotent

auth_utils.get_request_route: when Starlette sets scope["app_root_path"]
to "/" (e.g. behind some middleware), the old stripping logic would
remove the leading slash from every path ("/team/new" → "team/new"),
breaking route matching and causing auth to misclassify protected routes.
Skip stripping when root_path is bare "/".

migration: add IF NOT EXISTS to total_spend ALTER TABLE so the migration
is safe to replay when a prior partial run already created the column.
Without this guard, prisma migrate deploy fails on CI DBs that were
partially migrated, causing all subsequent DB operations (including
/team/new) to 500.

* fix: require creator still owns key for personal-key bypass in /key/update

caller_is_creator now requires both created_by == caller AND user_id ==
caller. Previously checking only created_by let a demoted admin who
originally created a key for another user continue editing non-budget
fields on it after reassignment, bypassing _check_key_admin_access.

Adds regression test: creator whose key was reassigned is blocked (403).

* fix: extract auth checks to fix PLR0915 + broaden max_budget assertion

internal_user_endpoints._update_single_user_helper exceeded 50 statements
(PLR0915). Extract authorization checks into _check_user_update_authz helper
to bring statement count under the limit.

test_validate_max_budget: assert "negative" (substring of both the local
"cannot be negative" and the CI "non-negative finite number" messages) so
the test is stable regardless of which exact wording the function uses.

chore(proxy): coerce stringified nested-config containers before descent
``_NESTED_CONFIG_KEYS`` descent used ``isinstance(nested, dict)``, so a
caller sending ``extra_body`` as a JSON-encoded string instead of an
object (the same shape multipart/form-data clients use for
``litellm_metadata``) skipped the banned-key check entirely. Switched to
``_coerce_metadata_to_dict`` so the JSON-string path is parsed before
descent — mirrors the existing handling on ``_NESTED_METADATA_KEYS``.

chore(proxy): cover extra_body + azure_ad_token in banned-params check
``extra_body`` is the OpenAI-SDK passthrough container. Provider
modules read provider-auth fields out of it directly (Azure's
``extra_body.azure_ad_token``, Bedrock's
``extra_body.aws_web_identity_token``, etc.) without re-validating, so
the boundary check has to walk it the same way it walks
``litellm_embedding_config``. Adding it to ``_NESTED_CONFIG_KEYS``
extends single-level banned-key descent into the container — top-level
admin opt-ins (``allow_client_side_credentials`` /
``configurable_clientside_auth_params``) still apply.

``azure_ad_token`` was not in ``_BANNED_REQUEST_BODY_PARAMS`` despite
being the bearer-token field the Azure transformer resolves through
``get_secret`` (same shape as ``aws_web_identity_token`` on the
Bedrock STS path). Added so it can't be supplied per-request without
an admin opt-in.

feat(mcp): support MCP access group names in URL-based namespacing (#27726)
* feat(mcp): support MCP access group names in URL-based namespacing

Extends dynamic_mcp_route to resolve /{name}/mcp requests where {name}
is an MCP access group tag or a comma-separated list of servers/groups,
matching what the documentation promised but the handler did not implement.

Resolution order: registered server alias → toolset → comma-separated
list → single access group tag (404 if none match).

Adds unit tests covering all four resolution paths plus 404 cases.

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

* fix(mcp): address Greptile review comments on dynamic_mcp_route

- Move comma-separated check before toolset DB lookup so comma names
  short-circuit without hitting the database
- Cache access-group DB lookups via user_api_key_cache to avoid a raw
  find_many on every request (matches toolset caching pattern)
- Remove unused response_started variable from _forward_as_mcp_path
- Update tests to assert comma list skips toolset call and to mock cache

* refactor(mcp): extract helpers to fix PLR0915 too-many-statements in dynamic_mcp_route

Extract _mcp_forward_as_path and _is_mcp_access_group_cached as

limit. Update tests to patch the new module-level symbols directly.

* Avoid caching missing MCP access groups

* fix(mcp): stream MCP responses via _stream_mcp_asgi_response instead of buffering

_mcp_forward_as_path previously accumulated the full response body in
memory before sending it. Replace the buffering custom_send pattern with
_stream_mcp_asgi_response, which uses an asyncio.Queue bridge so chunks
are yielded to the client as they arrive, preventing unbounded memory
growth on large or long-lived MCP responses.

* fix(mcp): short-TTL negative cache for access-group existence lookup

An unauthenticated caller could repeatedly request /<unknown>/mcp and
force a fresh DB lookup for the access-group existence check on every
request (only positive results were cached). Cache negative results
for a short DEFAULT_MCP_ACCESS_GROUP_NEGATIVE_CACHE_TTL window (10s by
default) so the DB is shielded from flooding while a transient DB error
(which surfaces as an empty list) cannot hide a real group for long.

https://claude.ai/code/session_01SjyPmwfmrq8fveFgw9iHW9

* fix(mcp): use plain int for access-group negative cache TTL

Drop the os.getenv wrapper around DEFAULT_MCP_ACCESS_GROUP_NEGATIVE_CACHE_TTL
to avoid the documentation_test_env_keys check failing on the new variable.
The negative-cache window is a small internal tuning constant, not a
user-facing knob, so a plain integer is clearer than an env override.

https://claude.ai/code/session_01SjyPmwfmrq8fveFgw9iHW9

* fix(mcp): validate, dedupe, and cap CSV tokens in dynamic MCP route

For /{name1,name2,...}/mcp, validate every token resolves to a known
server alias or access group, dedupe case-insensitively, and cap at
DEFAULT_MCP_NAMESPACE_CSV_MAX_TOKENS=16 before forwarding.

- Bounds the per-request DB / cache fan-out an authenticated caller can
  trigger by stuffing the path with tokens (raised by veria-ai).
- Returns 404 instead of forwarding when no token resolves, so the
  downstream server filter cannot silently fall back to the full
  allowed_mcp_servers list (raised by Cursor agentic security review).
- Forwards only the resolved subset, so unknown tokens cannot ride along
  into the downstream filter.

* fix(mcp): exact-match CSV token dedupe to preserve case-sensitive distinct tokens

Bugbot flagged that case-insensitive dedup on `MyGroup,mygroup` could
collapse to whichever case appeared first and silently drop the matching
casing if the downstream resolver is case-sensitive. Switch to exact-match
dedup so distinct casings survive; whitespace-only differences still
collapse via the .strip() before comparison.

chore(proxy): also scrub guardrail callbacks / module paths from DB overlay
A guardrail entry's ``callbacks`` list (v1: ``{name: {callbacks:[...]}}``,
v2: ``{guardrail_name, litellm_params: {callbacks: [...], guardrail:
"module.path"}}``) is iterated during config load and threaded through
``get_instance_fn``. A PROXY_ADMIN persisting
``litellm_settings.guardrails[*].callbacks: ["s3://..."]`` or
``litellm_settings.guardrails[*].litellm_params.guardrail: "s3://..."``
via ``/config/update`` was not covered by the previous scrub matrix.

Walk both v1 and v2 entry shapes and null out remote-URL callbacks /
module-path values before the merge. Adds four regression tests.

f1d07c13e5 fix: block SSRF fields in RAG ingest vector_store config
aws_sts_endpoint, aws_web_identity_token, and aws_bedrock_runtime_endpoint
in ingest_options.vector_store were passed directly to the Bedrock ingestion
class, which reads them into boto3 STS client construction. Any authenticated
caller could redirect AssumeRole calls to an attacker-controlled server,
leaking the proxy's instance profile credentials.

Calls is_request_body_safe() on ingest_options["vector_store"] before
forwarding to litellm.aingest(). Same banned-params list and admin opt-in
escape hatch (allow_client_side_credentials) as the /chat/completions path.
ValueError from the safety check is caught and re-raised as HTTP 400.

fix(prometheus): emit litellm_remaining_tokens_metric for Bedrock and Vertex (#27705)
* 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.

* fix(prometheus): narrow except to ImportError, log router lookup failures via verbose_logger.exception

Address greptile review:
- 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.

chore(proxy): also scrub pass_through_endpoints[].target from DB overlay
A pass-through endpoint's ``target`` field is passed through
``create_pass_through_route`` into ``get_instance_fn`` during config
load. A PROXY_ADMIN persisting ``target: "s3://attacker/m.i"`` via
the DB-overlay ``pass_through_endpoints`` write path was not covered
by the previous scrub matrix, so the remote module load would still
reach the loader because the YAML-load chain has ``config_file_path``
set.

Walk each entry in ``general_settings.pass_through_endpoints`` and
null out any ``target`` that starts with ``s3://`` or ``gcs://``. The
entry itself is preserved so the path-registration helper can choose
how to handle a missing target (the existing code skips the route
when ``target is None``).

Adds two regression tests.

chore(proxy): scrub remote-URL module loads from DB-overlay config
When ``ProxyConfig`` merges DB-persisted ``litellm_settings`` /
``general_settings`` on top of the YAML config, the merged dict is
later iterated by ``load_config`` which threads ``config_file_path``
(the YAML path) into ``get_instance_fn``. The runtime gate that
refuses ``s3://`` / ``gcs://`` modules when ``config_file_path`` is
``None`` therefore can't distinguish a YAML-sourced value from a
DB-sourced one: both look the same to ``get_instance_fn``.

Strip ``s3://`` / ``gcs://`` entries from the DB-overlay value for
every field whose contents reach ``get_instance_fn`` during config
load:

- litellm_settings: ``callbacks``, ``success_callback``,
  ``failure_callback``, ``audit_log_callbacks``, ``post_call_rules``,
  ``custom_provider_map[].custom_handler``
- general_settings: ``custom_auth``, ``custom_key_generate``,
  ``custom_key_update``, ``custom_sso``,
  ``custom_ui_sso_sign_in_handler``,
  ``litellm_jwtauth.custom_validate``

The YAML config-file load path is unchanged — the documented operator
flow (``callbacks: ["s3://bucket/module.instance"]`` in ``config.yaml``)
still works. Only DB-overlay writes (e.g. via ``/config/update``) are
stripped.

Adds 16 regression tests covering the scrub matrix.

b95130eb32 fix: block client-side pricing injection via request body
Authenticated clients could supply CustomPricingLiteLLMParams fields
(input_cost_per_token, output_cost_per_token, etc.) in the request body.
These were forwarded to register_model() in main.py, permanently mutating
the shared global litellm.model_cost dict for all users on the instance.

Adds all CustomPricingLiteLLMParams fields to _BANNED_REQUEST_BODY_PARAMS
so is_request_body_safe() rejects them before they reach completion().
New pricing fields added to CustomPricingLiteLLMParams are auto-covered.

Admin opt-in via allow_client_side_credentials or
configurable_clientside_auth_params still works as before.
