Three P1 defects from the auth_v2 review, plus the policy-admin flag guard:

- JWKS cache was dead: JWKSProvider was rebuilt per request, so its TTL cache
  never survived and every JWT auth refetched the JWKS over the network. Providers
  are now cached per jwks_uri at module level.
- Inference with no model bypassed casbin: a body omitting "model" skipped the
  call check entirely, so a subject with no grants could reach inference. Now a
  model-less inference request is denied up front (before any enrichment/budget).
- Policy-admin endpoints used a v1 _require_admin role check that rejected
  JWT/OAuth2 admins casbin had already authorized. Removed it - the routes are in
  the casbin route map (policy read/write/delete), so user_api_key_auth enforces
  them - and added a per-request flag guard so the unconditionally-registered
  router 404s when auth_v2 is off.

Regression tests for each. mypy clean on 23 files, 143 tests green.

4cd7b8c17a feat(proxy): auth_v2 authz observability metrics
Adds an in-process, dependency-free metrics collector so the authz layer is
observable: decision counts (keyed decision/resource/action), authz latency
(count + sum over the casbin enforce call), and policy-cache hit/miss.

- metrics.py exposes a singleton with observe_decision / observe_latency /
  record_cache and a typed snapshot() for a /metrics export at the edge.
- The authorizer counts every allow/deny/loud-open and times the enforce call;
  the entry point does the same for the model-call decision; the policy store
  records cache hit vs miss. No hot-path dependency - just counters.

Fully typed (no new bare Any), mypy clean on 23 files, 141 tests green, still
imports with casbin/authlib absent.

0bfa98afa1 feat(proxy): auth_v2 decision audit trail
Every authorization decision now flows through one audit record - the compliance
trail enterprise auth needs and the biggest gap called out in the design review.

- audit.py: a frozen AuthzDecision (decision, subject, domain, obj, action, route,
  reason, auth_method) and record(), which logs the decision and fans out to any
  registered sinks (DB / SIEM). Sinks are isolated: a failing sink is logged but
  never affects the request outcome.
- The authorizer records allow, deny, and loud-open for every governed and
  ungoverned control-plane route; the entry point records the model-call (call)
  decision on the inference path. auth_method is threaded through so the record
  shows how the principal authenticated.
- register_sink / reset_sinks exported for wiring a durable sink.

Fully typed (no new Any), mypy clean on 22 files, 134 tests green, still imports
with casbin/authlib absent.

69a8d4f986 refactor(proxy): fully type auth_v2 - eliminate every avoidable Any
The decision core used Any where it was over-cautious about coupling. Replace it
with real types (under TYPE_CHECKING, so the framework-free core stays import-
light) and small Protocols:

- identity is UserAPIKeyAuth end to end (authenticators, entry, principal,
  context, stages); the authenticator chain returns it, not Any
- SupportsEnforce types the authorizer's engine param; CasbinRuleRow / PolicyDB /
  PolicyAdminDB type the dynamic Prisma casbin-rule access (read and write),
  narrowed with one explicit cast at the adapter boundary
- AuthContext deps are PrismaClient / UserApiKeyCache / ProxyLogging / Span
- loaders, settings, key sets, role conversion all carry their real types

The only Any left is Dict[str, Any] for genuinely arbitrary JSON (decoded JWT
claims, RFC 7662 introspection responses, request bodies) - that is the honest
type, not a gap. Verified: mypy clean on all 21 files, zero bare Any annotations,
129 tests green, still imports with casbin/authlib absent.

764ffd834e refactor(proxy): group auth_v2 into authn/authz/stages subpackages
Pure move (git mv, history preserved): the flat 17-file package hid the
architecture behind an alphabetical wall. Group by request phase so the module
is self-documenting:

  authn/   authenticators, jwt_claims, jwt_verifier, oauth2_introspection
  authz/   enforcer + model.conf, authorizer, route_map, policy_store, policy_admin
  stages/  enrichment, end_user, budgets
  (top)    entry, context, principal, management_endpoints, __init__

No content changes beyond rewired relative imports; tests moved to mirror the
layout. Behavior is identical — the same 129 tests pass, mypy/black/ruff clean,
and the package still imports with casbin/authlib absent.

85b5920528 feat(proxy): auth_v2 enforces team/org/global budgets by reusing v1's functions
Closes the hierarchy-budget gap: team, organization, and global caps live in v1's
common_checks (not the pre-call hooks), which auth_v2 does not run, so they were
unenforced under v2. enforce_hierarchy_budgets calls the exact same functions v1
uses - _team_max_budget_check, _organization_max_budget_check, and
get_global_proxy_spend + _global_proxy_budget_check - so there is one budget
implementation with two callers (true single authority), with the correct
spend-counter conventions and no edit to v1's path. Wired into the inference
branch for all login types; a breach surfaces as the same 429 ProxyException v1
raises.

Verified in-process: a team over budget is blocked (BudgetExceededError), under
budget is allowed, and a teamless identity is a no-op. Real-counter accuracy
across pods remains a live check (see INTEGRATION.md).

1c8c600476 test(proxy): verify auth_v2 budget enforcement on an enriched identity
Drives the real max_budget_limiter pre-call hook with an enrichment-shaped
identity (teamless JWT/OAuth: no key, user-level budget filled from the user
row), mocking only the spend counter, to confirm the enrichment -> hook chain:
over budget -> 429, under budget -> allowed, no user budget -> no personal
enforcement, and a team member's personal budget is skipped (documenting that
team users are governed by the team budget, the item-4 gap). Real-counter
accuracy is the one piece still needing a live proxy.

0553eda4ab test(proxy): end-to-end auth_v2 flow through the real FastAPI dependency
In-process integration test with TestClient and an in-memory Prisma stand-in,
exercising the real request path without a running proxy or provider keys (the
allow/deny decision happens at auth time, before any model call):

- flag dispatch -> user_api_key_auth -> v2 entry -> authenticator chain ->
  casbin -> 403/200
- master key resolves to proxy_admin and passes a governed route
- a non-admin with no grant is denied; granting a role and assigning it (live
  policy CRUD) then unlocks the route, proving the cache reset on write
- the _require_admin gate rejects a non-admin over the wire
- model calls require the `call` permission: denied without a grant, allowed
  after granting call on gpt-* and assigning it

This is the wiring that unit tests can't cover, verified in CI.

3c1b685a43 feat(proxy): wire auth_v2 telemetry via seed_request_identity; drop speculative helper
auth_v2 now seeds request-identity Baggage by calling seed_request_identity at the
auth boundary in each entry branch (model included for inference), the same
SDK-free seeder v1 uses. It propagates team/key/user identity to every downstream
route span and no-ops when the OTel SDK is absent or V2 isn't active, so it's safe
to call unconditionally.

This is the established OTel v2 mechanism, so the earlier identity_span_attributes
helper (and its module/tests) was speculative and is removed. Only live
verification of the exported spans remains; see INTEGRATION.md.

5493dd26ff test(proxy): cover auth_v2 policy-admin gate (_require_admin) - privilege escalation guard
The policy CRUD endpoints were gated by _require_admin but it had no test. Add
deny/allow coverage: only PROXY_ADMIN may edit policies; view-only admins, every
other role, and no role are rejected with 403. This is the guard that stops a
non-admin from editing the casbin policy store, so a silent regression here would
be a privilege escalation.

205328bfb7 feat(proxy): auth_v2 identity enrichment so budget/limit hooks work for non-key logins
Virtual keys arrive fully populated via get_key_object; master/JWT/OAuth logins
returned a thin identity, so the existing pre-call budget/limit hooks read None
and enforced nothing for them. enrich_identity copies the user/team budget+limit
fields 1:1 from the user/team rows into the identity's distinct user_*/team_*
slots, filling only unset fields (never overriding an already-resolved value).

Wired into the inference path for non-virtual-key logins, with get_user_object /
get_team_object injected as loaders so the mapping is unit-tested without a DB.
Additive by construction: these logins enforce nothing today, so it cannot
regress existing behavior. The exact enforcement still needs a live rate-limit
check before it is trusted; see INTEGRATION.md.

fd638b484a feat(proxy): auth_v2 end-user resolver + telemetry stages reading the context
Adds the first two pipeline stages that consume RequestAuthContext instead of
the auth gate doing their work:

- end_user.resolve_end_user: extracts the customer (reusing the existing
  request-body/header logic) and records it on the context via attach_end_user.
  Validation is dependency-injected so it is testable without a DB. Wired into
  the inference path so the context carries the end-user for spend attribution.
- telemetry.identity_span_attributes: returns OTel attributes for the request's
  identity, for the route span (OTel v2) to set. Telemetry reads the context
  rather than auth seeding the span; absent fields are omitted.

Both are pure/injectable and unit-tested; the contract stays the single source
of truth. Type-safe (mypy), formatted, linted.

1685c2a9bc feat(proxy): typed RequestAuthContext - the auth_v2 contract for downstream stages
Introduces the single, type-safe object every post-auth stage reads instead of
poking at request.state with untyped attribute access. auth_v2 populates it once
(identity, principal, auth_method, route, end_user_id) after authn+authz and
publishes it via set_auth_context; budget/limit hooks, the end-user resolver, and
the telemetry span consume it through get_auth_context / try_get_auth_context.

- RequestAuthContext is a frozen dataclass; attach_end_user replaces rather than
  mutates, so one stage can't clobber another's view
- identity is annotated under TYPE_CHECKING so the contract is statically typed
  without coupling the decoupled core to the heavy litellm import
- authenticators now advertise an AuthMethod and the chain returns a typed
  AuthResult, so how a request authenticated is recorded for telemetry
- context is set in every branch (control, model-call, loud-open)

Verified type-safe with mypy. This is the linchpin for moving budgets, end-user
resolution, and telemetry out of the auth gate into their own stages.

ebb965d4c2 feat(proxy): auth_v2 model-call access is a role permission, not the legacy field
Calling a model is now the `call` action on the `model:<id>` object, decided by
the same casbin role engine as everything else. Grant it via a role (wildcard
objects like model:gpt-*, or g2 groups) or directly to a key/user subject. The
legacy key.models list and access-group expansion are no longer consulted, so
with no grant a key can call nothing (clean-slate default-deny).

Removes the separate data-plane predicate (data_plane.py and its conf/tests);
the inference path now runs the same enforcer the control plane uses, extracted
into a shared _build_enforcer helper. Adds `call` to the valid policy actions.

Note: this puts a casbin check on the inference hot path. It builds the enforcer
per request from the short-TTL policy snapshot; caching a long-lived in-memory
enforcer with cross-pod invalidation is the next step before this is enabled at
real traffic.

08f2e924f3 feat(proxy): auth_v2 data-plane honors model access groups (v1 parity)
The inference gate now allows a model when the key lists an access-group name
the model belongs to, mirroring v1 model_in_access_group. The group lookup is
resolved from the router in the entry point and injected into can_call_model,
which stays a pure predicate. Closes the access-group parity gap flagged when
the data plane moved off casbin; name, wildcard, and sentinel matching are
unchanged.

037df6ada3 feat(proxy): auth_v2 governs credentials via method-aware route matching
Credentials are REST-style: the verb is the HTTP method (POST /credentials is
create, GET is list) and the id is in the path, which the verb-in-path RPC
matcher cannot express. Adds method-aware, prefix-capable matching for these
resources and governs the credentials admin surface.

Fixes a latent bypass while wiring this: authorize() re-matched the route
without the method, so any REST route would have resolved to None inside
authorize() and been loud-opened even when the entry point had classified it as
governed. The method is now threaded through. Path-param ids are not extracted
yet, so credential objects stay at "credential:*" (per-id policies a follow-up).

4ffb474945 feat(proxy): auth_v2 governs mcp_server and guardrail admin surfaces
Governs the collection-level management operations (register/list/health/
submissions) for MCP servers and guardrails, mapped to read/write with
wildcard objects since they are not per-id. Runtime guardrail verbs
(apply_guardrail, test_custom_code) remain loud-open as data/runtime concerns,
not management.

04bb7f2361 feat(proxy): auth_v2 governs vector_store, budget, customer resources
Extends the control-plane route map to the remaining clean-CRUD management
resources, following the established read/write/delete/manage pattern with
per-resource ids. These routes were loud-open before, so this only tightens
coverage. Non-uniform surfaces (guardrails, mcp servers, credentials) stay
deferred because their verbs don't map cleanly onto the four actions.

Also corrects two stale comments that still described the data plane as casbin
ABAC after it became a plain predicate.

940791576d fix(proxy): auth_v2 JWT node falls through cleanly when unconfigured
A token shaped like a JWT (non sk-, two dots) was claimed by the JWT
authenticator even when no jwks_uri was configured, producing a 500 from the
settings loader. It now only claims JWT-shaped tokens when JWT auth is actually
configured, so an unconfigured deployment ends the chain in a clean 401.

2a85db9a91 refactor(proxy): auth_v2 data-plane model gate is a plain predicate, with wildcard parity
The inference-path model check ran through a casbin enforcer whose matcher was a
trivial membership test (unrestricted || requested in allowed). On the hot path
that is pure overhead and indirection; casbin earns its keep on the control
plane (roles, deny-override, domains), not here. Replaces it with a direct
predicate and removes data_plane.conf.

Also closes a parity gap with v1: the gate now honors wildcard patterns
(e.g. bedrock/*, openai/*) via v1's is_model_allowed_by_pattern semantics, where
before it only matched exact names and would over-deny wildcard model lists.
Access-group expansion remains a tracked follow-up.

25823cba7f fix(proxy): pin auth_v2 JWT verification to asymmetric algorithms
The JWT verifier used authlib's default decoder, which permits HMAC alongside
RSA/EC. With a JWKS of public keys that is the RS256->HS256 confusion setup: an
attacker signs HS256 using the public key as the HMAC secret. authlib happens to
reject this today via key-type checks, but relying on that is fragile and breaks
the moment a symmetric key enters the key set. Pinning the accepted algorithms
to an asymmetric allowlist closes the class outright.

Adds a regression test that forges an HS256 token from the JWKS public key and
asserts it is rejected.

de105b2d2d feat(proxy): auth_v2 slice 8 - domain-scoped roles + docs
Adds tenancy via domain-scoped role assignment (casbin g3): a role can be
granted globally (g) or only within a domain (g3), e.g. admin within team:eng
but nowhere else. The matcher accepts either, so existing global assignments are
unchanged. The policy store buckets g/g2/g3 separately and the assignment
endpoint takes an optional domain.

Adds litellm/proxy/auth/v2/README.md documenting configuration, the policy
admin API, and a live verification runbook.

Tests cover domain-scoped vs global role resolution, coexistence of both, the
g3 split in the policy store, and g3 assignment rule construction.

22767a1c62 feat(proxy): auth_v2 slice 7 - OAuth2 token introspection authenticator
Completes the authn surface from the plan with an RFC 7662 introspection node
for opaque bearer tokens. Dispatched only for tokens that are neither virtual
keys nor JWTs, and only when an introspection endpoint is configured, so
unconfigured deployments fall through to a clean 401 rather than calling out.

The introspection response parsing is a framework-free core: a token is valid
only when explicitly active=true, the subject claim is required, and OAuth
scopes map to a litellm role via an explicit scope->role map (unmapped scopes
grant no role). The HTTP introspection call is isolated from that core.

Tests cover inactive/missing-active rejection, missing subject, and scope
(string and list) to role mapping.

98aa7622a6 feat(proxy): auth_v2 slice 6 - keys/users/orgs resources, manage action, resource grouping
Expands control-plane governance to keys, users, and organizations (read/write/
delete), mirroring models and teams. Membership changes (team/member_add,
organization/member_add, etc.) become the `manage` action on their resource.

Adds casbin resource grouping (g2) so a policy can grant on a named group of
resource ids rather than one row per id; this is where litellm access groups
map in. The matcher prefers a group match and falls back to keyMatch, so
direct/wildcard object matching is unchanged when no g2 rules exist. The policy
store now splits g2 rows out from g groupings and the enforcer loads them under
the g2 role manager.

Tests cover grouped vs ungrouped access, preserved direct matching, the g2/g
split, and governance of the new resources and the manage action.

a1978bc707 feat(proxy): auth_v2 slice 5 - data-plane model access on the inference path
Brings inference under casbin too, via the hybrid design: control-plane access
stays RBAC policy rows, data-plane access (can this principal call this model)
is a casbin ABAC matcher over an attribute carried on the already-loaded key, so
the hot path reads no policy store and writes no per-key policy rows.

Inference routes (chat/completions, completions, embeddings, responses) now
authenticate and check the requested model against the principal's allowed-model
attribute. Semantics match v1: an empty models list, "*", "all-proxy-models" and
"all-team-models" are unrestricted; otherwise the model must be in the list.

Tests cover the allow/deny/unrestricted matrix and inference-route detection.

8dcfa9fc3c feat(proxy): auth_v2 slice 4 - policy administration API
Adds endpoints to manage casbin policies and role assignments without raw DB
inserts: add/remove a permission, add/remove a role assignment, and list rules
under /auth/v2/policy/*. Requests go through a validated, normalized core
(actions limited to read/write/delete/manage, effects to allow/deny, role and
object strings normalized) so malformed rules can't reach the policy table.

The policy surface governs itself: those routes are a "policy" resource in the
route map, so only a role permitted to manage policy (the bootstrap proxy_admin
role) can edit them, with an explicit proxy-admin check as defense in depth.
Writes reset the policy snapshot cache so changes take effect immediately.

Tests cover rule validation/normalization and the rule<->row conversion.

cde0c99f20 feat(proxy): auth_v2 slice 3 - authlib JWT authenticator
Adds a JWT node to the authenticator chain, dispatched on credential shape
(3-part token, not a sk- key). authlib owns the crypto: JWKS fetch with TTL
caching, kid-based key selection, signature verification, and exp/iss/aud
validation. A thin framework-free layer maps verified claims to an identity
using configurable claim names and an explicit upstream-role to litellm-role
map; unmapped role values are dropped rather than trusted.

JWT settings come from general_settings.auth_v2_jwt (or AUTH_V2_JWKS_URI etc.).
Verification failures normalize to 401 so callers never branch on authlib's
internal exception types.

Tests cover signature tampering, expiry, wrong audience/issuer, unknown signer,
and garbage input on the verifier, plus claim extraction and role mapping.

c596af04a4 feat(proxy): auth_v2 slice 2 - master-key authenticator + team resource
Adds a master-key authenticator ahead of the virtual-key node so the proxy admin
can authenticate under auth_v2 (slice 1 was virtual-key only, which locked the
master key out). Match is a constant-time exact compare; the raw key never
propagates downstream, a stable alias stands in for it.

Extends casbin governance to the team management plane (/team/new, /team/update,
/team/delete, /team/info) mirroring models. Team membership/permission routes
(member_add, etc.) stay loud-open, deferred with the recursive `manage` action.

Tests cover the master-key exact-match deny path (near-match, non-string, empty,
unconfigured) and team route governance.

0d5e14fcd1 feat(proxy): auth_v2 slice 1 - virtual-key authn + casbin model RBAC behind a flag
Introduces auth_v2 as a clean-slate, flag-gated auth path (general_settings
auth_version: v2). When on, the existing auth is bypassed entirely and requests
flow through a new authenticator chain plus a casbin authorization engine.

Slice 1 scope:
- Entry point fork in user_api_key_auth; v1 untouched when the flag is off
- Authenticator chain with a virtual-key node resolving identity via the
  existing key store (reuses get_key_object; no parallel identity storage)
- casbin engine: RBAC policy rows for the control plane, role bridged from the
  key's existing user_role; per-resource-id objects supported
- Governs the model-deployment management plane only (/model/new, /model/update,
  /model/delete, /model/info); every other route is loud-open and logs a warning
  so unprotected surfaces are never silent
- Policies/groupings stored in LiteLLM_CasbinRule, loaded on cold routes with a
  short snapshot cache; a bootstrap policy keeps proxy_admin fully authorized
- Decision core (enforcer, route map, principal, authorizer, policy store) holds
  no framework imports, so it is unit-testable in isolation

Tests cover the allow/deny matrix, deny-override, domain scoping, per-id
granularity, loud-open behavior, and policy loading.

Data plane (inference-time model access) and additional resources/mechanisms are
deferred to later slices. casbin governs everything eventually via ABAC matchers
over cached attributes; this slice lays the control-plane foundation.

* fix(azure): apply api_version fallback chain to image edit URL

`AzureImageEditConfig.get_complete_url` only read `api_version` from
`litellm_params`. When callers configured it via `litellm.api_version`
or `AZURE_API_VERSION`, the constructed URL had no `?api-version=` and
Azure responded `404 Resource not found`.

Apply the same fallback chain the Azure chat path already uses in
`common_utils.py`:

    litellm_params > litellm.api_version > AZURE_API_VERSION env >
    litellm.AZURE_DEFAULT_API_VERSION

Adds 5 unit tests pinning each layer of the chain plus a regression
guard for `api_base` that already carries `?api-version=`.

* feat(mcp): core sampling and elicitation flow with security hardening

- Add elicitation_handler.py: MCP elicitation/create relay with
  downstream client capability detection
- Wire sampling/elicitation callbacks in mcp_server_manager.py
  gated behind allow_sampling/allow_elicitation config flags
- Add allow_sampling/allow_elicitation fields to MCPServer type
- Fix session lock deadlock: skip lock for JSON-RPC response POSTs

* feat(bedrock_mantle): add gpt-5.5/gpt-5.4 Responses price-map entries

* refactor(bedrock_mantle): exclude gpt-oss instead of allow-listing gpt-5 for Responses routing

Frontier OpenAI models on Bedrock Mantle are Responses-only on /openai/v1/responses;
gpt-oss is the legacy family that also speaks chat-completions. Gate by excluding
gpt-oss (which keeps its chat-completions emulation) and defaulting everything else
to the native Responses config, so future frontier models (gpt-6, etc.) route
correctly without a code change. Verified against the live us-east-2 Mantle endpoint:
gpt-oss 400s on /openai/v1/responses while gpt-5.5 400s on both standard paths.

* test(bedrock_mantle): cover supports_native_websocket opt-out

Closes the one uncovered line flagged by codecov on the Responses config.
The assertion documents that Mantle Responses has no realtime/websocket
transport, so realtime routing must not attempt a socket it cannot serve.

* fix(bedrock_mantle): route file_search through emulation instead of forwarding to Mantle

BedrockMantleResponsesAPIConfig inherited supports_native_file_search()
-> True from OpenAIResponsesAPIConfig but never overrode it. Mantle has no
OpenAI vector stores, so a forwarded file_search tool is rejected with a
400 (verified upstream: Tool type 'file_search' is not supported). Opting
out, like the existing supports_native_websocket override, routes the tool
through LiteLLM's file_search emulation instead.

* fix(bedrock_mantle): only route openai.gpt frontier models to Responses

The previous gate excluded gpt-oss and routed every other model to the
native Responses config. But on Mantle only the OpenAI gpt frontier models
(gpt-5.x) are served on /openai/v1/responses; gpt-oss and the non-OpenAI
families (nvidia, mistral, google, zai, ...) are chat-completions only and
400 on that path. Allow-list the openai.gpt- family (excluding gpt-oss)
instead, so chat-only models fall through to the chat-completions emulation.
Verified against the live us-east-2 endpoint: nvidia.nemotron-nano-9b-v2
returns 400 on /openai/v1/responses and 200 on /v1/chat/completions.

* fix(proxy/cwe-209): strip Python traceback from HTTP 503 error responses

The /cache/ping endpoint included a full Python traceback in its 503 error
response body (inside the ProxyException message), leaking internal file
paths, line numbers, and call stacks to any caller. Two MCP route handlers
in proxy_server.py similarly interpolated str(e) into "Internal server
error" detail strings.

Fix: log the traceback server-side via verbose_proxy_logger.exception()
and omit it from the ProxyException payload / HTTPException detail returned
to clients. Tests updated to assert no "traceback" keyword or frame paths
appear in the 503 body, with a new dedicated regression test.

* fix(proxy/cwe-209): apply Greptile P2 fixes and add MCP exception-path tests

Greptile 4/5 review identified two remaining gaps and Codecov reported
0% coverage on the two MCP handler exception branches:

1. caching_routes.py — str(e) in "Service Unhealthy ({str(e)})" could
   still leak Redis hostnames/IPs; replaced with static "Service Unhealthy".
   HTTPException is now re-raised before the generic handler so the
   "cache not initialized" 503 still reaches callers with its detail.
   Removed the redundant str(e) arg from verbose_proxy_logger.exception()
   (exception() already appends the traceback automatically).

2. tests — two new unit tests cover the exception paths in
   dynamic_mcp_route and toolset_mcp_route that were previously at 0%:
   - test_dynamic_mcp_route_unexpected_exception_returns_500_without_traceback
   - test_toolset_mcp_route_unexpected_exception_returns_500_without_traceback

All 25 tests pass (9 caching + 16 MCP).

* test(caching_routes): restore precise assertion in test_cache_ping_no_cache_initialized

The assertion was weakened to `"Cache not initialized" in str(data)`, which
matches the raw string of the entire response dict and would pass even if the

Restore a targeted check on the parsed response: assert the exact string in
the correct field `data["detail"]`, matching FastAPI's HTTPException
serialisation format {"detail": "<message>"}.

* test(caching_routes): restore precise assertion and add CWE-209 no-cache path test

The assertion in test_cache_ping_no_cache_initialized was weakened to
`"Cache not initialized" in str(data)`, which matched against the raw string
representation of the entire response dict. This would pass silently even if
the error message moved to an unexpected field or the structure changed.

Restore a targeted assertion on the parsed field:
  assert data["detail"] == "Cache not initialized. litellm.cache is None"
matching FastAPI's HTTPException serialisation format exactly.

Add test_cache_ping_no_cache_does_not_expose_internals to show the code path
is still working correctly after the CWE-209 fix: verifies that the HTTPException
is re-raised as-is (no traceback, no source paths), and asserts the complete
response structure is exactly {"detail": "Cache not initialized. litellm.cache is None"}.

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

* fix(caching_routes): restore ProxyException envelope for null-cache 503

The except HTTPException: raise guard (added in the CWE-209 fix) caused
the null-cache HTTPException to escape as FastAPI's {"detail": "..."} shape
instead of the {"error": {...}} ProxyException envelope that callers expect.

Move the null-cache guard before the try block and raise ProxyException
directly so the response structure is consistent with all other /cache/ping
503s, and the except HTTPException: raise guard is only reachable by
unexpected downstream HTTPExceptions.

Update the two no-cache tests to assert the correct ProxyException envelope.

* Update utils.py (#26609)

* feat(pricing): add Snowflake Cortex REST API model pricing (#26612)

* feat(pricing): add Snowflake Cortex REST API model pricing

## Summary

Adds pricing and context window information for 20+ Snowflake Cortex REST API models to `model_prices_and_context_window.json`.

## What's included

- **7 Claude models** (sonnet-4-5, sonnet-4-6, 4-sonnet, 4-opus, haiku-4-5, 3-7-sonnet, 3-5-sonnet) — with prompt caching rates
- **4 OpenAI models** (gpt-4.1, gpt-5, gpt-5-mini, gpt-5-nano) — with prompt caching rates  
- **5 Llama models** (3.1-8b, 3.1-70b, 3.1-405b, 3.3-70b, 4-maverick)
- **1 DeepSeek model** (deepseek-r1)
- **1 Mistral model** (mistral-large2)
- **1 Snowflake model** (snowflake-llama-3.3-70b)
- **2 Embedding models** (arctic-embed-l-v2.0, arctic-embed-m-v2.0)

Each entry includes `input_cost_per_token`, `output_cost_per_token`, `cache_read_input_token_cost` (where applicable), `max_input_tokens`, `max_output_tokens`, and capability flags (`supports_function_calling`, `supports_vision`, `supports_prompt_caching`, `supports_reasoning`).

## Pricing source

All prices are in USD per token, sourced from the official [Snowflake Service Consumption Table](https://www.snowflake.com/legal-files/CreditConsumptionTable.pdf) — Tables 6(b) (REST API with Prompt Caching) and 6(c) (REST API).

## Context

The existing `snowflake/` provider has zero model entries in the pricing JSON, which means LiteLLM cannot track costs for Snowflake Cortex calls. This PR fills that gap.

## Related

- Existing provider: `litellm/llms/snowflake/`
- Cortex REST API docs: https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-rest-api

* fix(utils): copy extra_body before adding unknown params to prevent model config mutation (#29620)

Fixes #29615. In add_provider_specific_params_to_optional_params, the line:

    extra_body = passed_params.pop("extra_body", None) or {}

returns the original dict reference when extra_body is non-empty (truthy).
Subsequent writes like extra_body[k] = passed_params[k] then mutate the
shared model config object held by the router, poisoning /model/info and
all subsequent requests for that deployment.

The or {} short-circuit creates a new dict only when extra_body is falsy
(None or {}), which is why the bug does not reproduce with extra_body: {}.

Fix: wrap in dict() so we always work on a fresh shallow copy.

* fix(gemini/veo): move image from parameters into instances[0] (#29501)

* fix(gemini/veo): move image from parameters into instances[0]

Veo's predictLongRunning schema puts image (and prompt) on the
instances element; parameters is for aspectRatio/durationSeconds/etc.
The Gemini path was leaving image in params_copy, so it ended up
nested under parameters and the API silently ignored it.

The Vertex path already builds the instance dict explicitly, so this
just aligns the Gemini path with it.

Fixes #29498

* address greptile: unconditional pop + BytesIO test

- Pop `image` from params_copy unconditionally so it never reaches
  GeminiVideoGenerationParameters even when None, removing implicit
  reliance on Pydantic's extra-field-ignore.
- Add test_transform_video_create_request_image_filelike_goes_to_instance
  covering the BytesIO path (_convert_image_to_gemini_format) — round-trips
  the base64 to confirm encoding.
- Add test_transform_video_create_request_image_none_is_dropped covering
  the new None branch.

* fix(huggingface): handle special token text in embedding usage (#29660)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params (#29655)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params

ToolPermissionGuardrail builds self.rules and the compiled target/pattern
maps only in __init__. The base update_in_memory_litellm_params re-sets raw
attributes via setattr but never rebuilds those maps, so a guardrail updated
in place (PUT /guardrails, or the immediate in-memory sync) keeps enforcing
the construction-time rules until it is reinitialized (PATCH path, periodic
DB poll, or restart).

Extract the compile step into _load_rules and override
update_in_memory_litellm_params to rebuild from it (dict- and model-safe),
re-normalizing default_action / on_disallowed_action. Mirrors the existing
PresidioGuardrail override of the same method. Adds regression tests.

Fixes #29592.

* fix(guardrails): handle dict params in ToolPermissionGuardrail in-memory update

Delegate to super() only for LitellmParams input (the base setattr loop is
model-only); apply the raw-dict case inline. Fixes the mypy arg-type error
and makes the recompile work when the proxy passes the raw DB dict.

* fix(guardrails): preserve tool-permission rules on a partial in-memory update

A partial update (e.g. a LitellmParams whose rules field is None) ran through
the generic setattr, which set self.rules to None, and the recompile was
skipped, leaving the guardrail with no rules. Snapshot the previous rules and
restore them when the update carries no rules; an explicit empty list still
clears them. Adds a regression test for the rules-absent case.

Addresses the Greptile review note on #29655.

* fix(bedrock): stop base_model label from stripping tools/tool_choice (#29621)

* fix(bedrock): stop base_model label from stripping tools/tool_choice

A Router/proxy Bedrock deployment whose model_info.base_model is a friendly
label (e.g. claude-haiku-4-5) silently lost tools/tool_choice: the outgoing
Converse request was built without toolConfig, so the model behaved as if no
tools were provided. Worked in v1.84.0, regressed in v1.85.0, and with
drop_params=true it failed silently.

Two changes compound into the bug. completion() passed model_info.base_model
as the model argument to get_optional_params, so the real Bedrock model id
never reached supported-param resolution; and get_supported_openai_params
resolved the provider config's params from base_model or model, letting the
label fully replace the real model. For Bedrock the label resolves to no tool
support, so tools/tool_choice were dropped before transformation.

completion() now keeps model as the real deployment model and threads the
resolved base_model (kwarg or model_info) through separately, and
get_supported_openai_params treats base_model as additive: it returns the
union of the params supported by model and by base_model. A hint can only add
capabilities, never strip ones the real model already exposes, which also
preserves the original base_model behavior from #27717 and Azure's base_model
driven model-type detection.

Fixes #29618

* test(main): make base_model param test robust to new parametrize cases

Restore an explicit per-case expected_model_param literal instead of
hardcoding the gemini id, so a future case with a different model can't
produce a misleading assertion failure.

* fix(fireworks_ai): pass response_format json_schema through unchanged (#29606)

FireworksAIConfig.map_openai_params was rewriting the OpenAI strict
`{type: json_schema, json_schema: {name, strict, schema}}` shape into
`{type: json_object, schema: ...}` before sending to Fireworks, dropping
`strict` and `name` and changing the `type`. Per Fireworks' docs json_object
means "force any valid JSON output (no specific schema)", so the schema
constraint was effectively dropped and grammar-guided decoding never ran;
model output silently violated the schema.

The rewrite landed in #7085 (Dec 2024) when Fireworks did not yet accept
native json_schema. Fireworks accepts the OpenAI strict shape natively now,
so the rewrite has become a regression.

Removes the rewrite. Passes response_format through unchanged. Updates the
existing test_map_response_format to assert pass-through. Adds focused
regression tests in tests/test_litellm/ covering preservation of type,
strict, name, and schema body, plus that json_object alone still works.

* fix(test): use .value when comparing LlmProviders enum against string in test_default_api_base

* fix(test): iterate LlmProviders enum in test_default_api_base to avoid str pollution from custom provider registration

litellm.provider_list is a mutable global initialized to list(LlmProviders) but custom_llm_setup() appends plain provider strings to it. When a test_custom_llm.py test runs first in the same xdist worker, provider_list contains a str and calling .value on it raises AttributeError. Iterate the immutable LlmProviders enum instead, which is deterministic and what the check intends.

* fix(mcp): depth-aware JSON-RPC response detection and neutral speed-priority fallback

Replace the flat substring check in the truncated-body routing path with a
top-level-key scan so a JSON-RPC response whose result payload nests a
"method" field is still detected as a response and skips the session lock,
removing a deadlock against the in-flight tool call awaiting it.

Drop the inverse max_output_tokens speed proxy when no model exposes
output_tokens_per_second; context-window size does not track latency, so a
neutral score avoids biasing speedPriority toward the smallest-context model.

* fix(guardrails): make ToolPermission rule reload atomic on invalid regex

_load_rules appended each rule to self.rules before compiling its regex, so an
invalid pattern raised mid-loop after the bad rule was already live but without
a _compiled_rule_targets entry. _matches_regex reads a missing compiled target
as a None pattern and returns True, turning the bad rule into a match-all that
silently applies its decision to every tool. Via update_in_memory_litellm_params
(PUT /guardrails) this corrupted the live guardrail.

Build the parsed rules and compiled maps into locals and swap them in only after
every regex compiles, and restore the previous ruleset if a live update is
rejected, so an invalid regex now fails the update without leaving the guardrail
enforcing a broken policy.

* test(mcp): cover sampling conversion, model resolution, and elicitation relay paths

The MCP sampling and elicitation handlers shipped with partial test
coverage, leaving the response-to-MCP conversion, the model resolution
fallback chain, completion-kwargs assembly, guardrail routing, and the
entire elicitation relay untested. That pulled the PR's diff (patch)
coverage below the codecov threshold even though overall project
coverage rose.

Add focused unit tests for _convert_openai_response_to_mcp_result,
_convert_mcp_tools_to_openai, _convert_mcp_tool_choice_to_openai, image
and audio content conversion, the hint-matching and fallback branches of
_resolve_model_from_preferences, _build_completion_kwargs, the router and
guardrail-rejection paths of _run_guardrails_and_call_llm, the
handle_sampling_create_message success and error-propagation flows, the
marker-hoisting fallback for tool content on unexpected roles, and the
elicitation form/url/generic relay together with its decline paths

fix(gemini-realtime): use GA event names for Pipecat 1.3.x compatibility (#29662)
* fix(gemini-realtime): use GA event names for Pipecat 1.3.x compatibility

Pipecat v1.3.0 adopted the OpenAI Realtime API GA event naming:
  response.audio.delta          -> response.output_audio.delta
  response.text.delta           -> response.output_text.delta
  response.audio.done           -> response.output_audio.done
  response.text.done            -> response.output_text.done

The proxy was still emitting the old beta names; Pipecat's
`parse_server_event` raises "Unimplemented server event type" for any
unknown type, which killed the receive task handler and broke audio
playback and tool-call delivery.

Also:
- conversation.item.created -> conversation.item.added (already handled)
- client audio is buffered until backend setupComplete in deferred mode
- call_id fallback UUID when Gemini returns empty id
- status_details / token detail fields added to Pydantic-strict events

The _GA_TO_BETA_EVENT_TYPES map in RealTimeStreaming already translates
GA names back to beta for clients that opt in with the openai-beta
header, so legacy clients are unaffected.

fix(proxy): disable proxy buffering on streaming SSE responses (#29557)
Streaming responses from the proxy (/chat/completions, /v1/messages,
/v1/responses, assistants) all return through create_response() but never
sent the headers that tell an intermediary reverse proxy not to buffer the
SSE stream. nginx with the default proxy_buffering, k8s ingress-nginx, and
Envoy/Istio sidecars therefore hold the whole stream and release it in one
batch, which looks like a broken/buffered stream to the client even though
litellm is yielding chunks incrementally.

Add Cache-Control: no-cache and X-Accel-Buffering: no to every
StreamingResponse create_response() returns, matching what the proxy already
does for its own usage/policy SSE endpoints. Fixes #28384.

#29612 exempts UI/CLI session tokens from the key budget ceiling when they
create a team key, keyed on data.team_id. That value is read after the
default_key_generate_params loop can populate team_id, so on deployments that
set default_key_generate_params.team_id a request the caller did not scope to a
team is treated as a team key and skips the ceiling. Capture _requested_team_id
before defaults run and key the exemption off it, mirroring how
_requested_max_budget is already captured. Requests the caller did not scope to a
team keep the ceiling.

fix(key_generate): exempt UI/CLI session tokens from the budget ceiling for team keys (#29612)
Non-admin users creating a team key through the UI were rejected with
"max_budget cannot exceed the caller's own max_budget (0.25)". The request is
authenticated by a UI/CLI session token whose max_budget is the per-session chat
spend cap (max_ui_session_budget, default $0.25), and the delegated-authority
budget ceiling (GHSA-q775-qw9r-2r4g) treated that cap as a delegation limit.

Skip the ceiling only when a session token creates a team key (data.team_id set);
that key's spend is bounded by the team budget at request time. Personal keys and
every other non-admin caller keep the ceiling, so a session token cannot mint an
arbitrary-budget personal key.

fix(ci): keep coverage rename green when a parallel node runs no tests (#29608)
* fix(ci): keep coverage rename green when a parallel node runs no tests

local_testing_part1 and local_testing_part2 run with parallelism 4. When
CircleCI reruns only the failed tests, the failed test lands on a single
node and the other nodes receive an empty bucket, so pytest never writes
coverage.xml or .coverage. The unguarded "mv coverage.xml ..." then exits
1 and turns the whole job red even though the rerun passed; the next
persist_to_workspace step would fail the same way on the missing paths.

Guard the rename so a node with no coverage emits empty placeholders
instead. coverage combine tolerates the empty files, so the downstream
upload-coverage job keeps the real nodes' data intact.

* fix(ci): pre-create test-results in litellm_router_testing for empty-bucket reruns

litellm_router_testing also runs with parallelism 4. On a rerun of only the
failed tests, a node can receive no tests, so the test command never creates
test-results and the final store_test_results step can fail on the missing
path. Pre-create the directory up front, matching what local_testing_part1
and part2 already do and CircleCI's own guidance for parallel reruns.

* test(openai): retry wildcard chat completion on transient OpenAI 500

build_and_test reddened on test_openai_wildcard_chat_completion when the
real gpt-3.5-turbo-0125 call returned an OpenAI 500 ("The server had an
error while processing your request"). The base branch passed the same
call concurrently, so the 500 is an intermittent OpenAI server error, not
a regression. Add the same pytest-retry marker the sibling real-call tests
in this file already use so a transient upstream 500 no longer fails CI.

fix: passthrough endpoints duplicate logs (#29598)
* fix duplicate cost callbacks for anthropic streaming pass-through

Two bugs caused _PROXY_track_cost_callback to see stream=True +
complete_streaming_response=None on every streaming pass-through request,
making the dedup guard in dispatch_success_handlers permanently inactive:

1. pass_through_endpoints.py created the Logging object with stream=False
   for all requests. _is_assembled_stream_success short-circuits on
   self.stream is not True, so has_dispatched_final_stream_success was
   never set and any second dispatch went through unchecked.
   Fix: set logging_obj.stream = True after stream detection.

2. _create_anthropic_response_logging_payload set complete_streaming_response
   inside the try block after litellm.completion_cost(), so a pricing error
   caused an early return without setting it on model_call_details.
   Fix: set complete_streaming_response before the try block.

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

* fix stream

* add stream to logging obj

* test(pass_through): give mock logging object a real model_call_details dict

The anthropic passthrough logging payload now records the assembled
response on model_call_details before cost calculation, which requires
model_call_details to support item assignment. In production it is always
a dict; the existing unit test stubbed the logging object with a bare Mock
whose attribute is not subscriptable, so the new assignment raised
TypeError. Use a real dict to match the production logging object.

* test(pass_through): cover streaming logging-obj stream flag

The streaming branch of pass_through_request that marks the logging object
as streaming (logging_obj.stream and model_call_details["stream"]) had no
unit coverage, so the patch coverage gate flagged it. Add a regression test
that drives a streaming pass-through request through pass_through_request and
asserts the logging object is flagged as a stream before dispatch.

* test(pass_through): cover SSE-response stream flag fallback branch

The auto-detected streaming branch of pass_through_request (when a request
that was not flagged as streaming returns a text/event-stream response) sets
logging_obj.stream and model_call_details["stream"] but had no unit coverage,
so the codecov patch gate failed at 60%. Drive a non-streaming pass-through
request whose upstream response is SSE through pass_through_request and assert
the logging object is flagged as a stream before dispatch.

* fix(pass_through): gate complete_streaming_response on stream flag

perform_redaction only scrubs complete_streaming_response when
model_call_details["stream"] is True. Setting it unconditionally for
non-streaming Anthropic pass-through responses left the assembled
response unredacted in model_call_details, which is handed to logging
callbacks as kwargs when message logging is disabled. Only record it for
actual streaming responses so redaction always applies.

feat(arize/phoenix): OpenInference rendering parity — tool_calls, cost, passthrough I/O, session/user, multimodal, cache tokens (#28800)
* feat(arize): enrich OpenInference attributes for better span rendering

Pure rendering enhancements to the Arize / Arize Phoenix integration. No
existing attribute keys or values are removed or overwritten; every new
emit is independently try/except-wrapped and fires only when its source
data is present so existing behavior is preserved.

What this adds
- Coerce non-dict response objects (e.g. httpx.Response from passthrough
  routes) via JSON decode so id/model/usage extraction stops crashing
  with "'Response' object has no attribute 'get'". Dicts and Pydantic
  objects with .get pass through unchanged.
- Set OPENINFERENCE_SPAN_KIND defensively early so a downstream failure
  can't blank the kind; the original late write (incl. TOOL upgrade) is
  preserved.
- Add "passthrough" keyword to _infer_open_inference_span_kind so
  allm_passthrough_route / llm_passthrough_route resolve to LLM instead
  of UNKNOWN.
- Emit cache token breakdown: LLM_TOKEN_COUNT_PROMPT_DETAILS_CACHE_READ /
  _CACHE_WRITE / _AUDIO. Sources covered: OpenAI prompt_tokens_details
  and Anthropic / Bedrock cache_{read,creation}_input_tokens.
- Render assistant tool_calls on both input and output messages via
  MESSAGE_TOOL_CALLS.* (Pydantic-aware, handles ModelResponse choices).
  Tool-result input messages also get MESSAGE_TOOL_CALL_ID and
  MESSAGE_NAME.
- Render multimodal list-shaped content via MESSAGE_CONTENTS.* (OpenAI
  image_url, Anthropic source.{media_type,data} as data: URI). Legacy
  MESSAGE_CONTENT write is unchanged.
- Emit SESSION_ID (end_user_id / trace_id), USER_ID (only when not
  already set by optional_params.user or model_params.user), and
  litellm.{team_id,team_alias,key_alias} from StandardLoggingPayload
  metadata.
- Emit llm.response.cost as float from StandardLoggingPayload.response_cost.
- Bedrock / Anthropic passthrough normalization: extract input from
  additional_args.complete_input_dict and output from the coerced
  provider response so INPUT_VALUE / OUTPUT_VALUE / LLM_INPUT_MESSAGES /
  LLM_OUTPUT_MESSAGES are populated. Only runs when call_type contains
  "passthrough" / "pass_through".

Tests
- 15 new unit tests covering each addition plus explicit regression
  guards (USER_ID overwrite protection, passthrough normalizer scope,
  coerce identity for dicts/.get-bearing objects, no spurious cache
  emits).
- Existing test_arize_set_attributes count bumped from 26 to 27 to
  account for the additional defensive span.kind write (same value,
  written twice).
- tests/test_litellm/integrations/arize/: 70 passed (55 baseline + 15
  new). tests/test_litellm/integrations/test_opentelemetry.py: 221
  passed.

* refactor(arize): collapse additive try/except blocks into _safe_emit helper

The additive attribute emitters all share the same shape: run a callable,
swallow any exception to debug log so it cannot blank the span. Hoisting
that pattern into a single _safe_emit(label, fn, *args, **kwargs) helper
removes 5 repeated try/except blocks. Behavior unchanged; arize test
suite still passes (70/70).

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

* fix(arize): emit cost under canonical llm.cost.total key

Arize's "Total Cost" column reads the OpenInference-standard
`llm.cost.total` attribute. The previous custom `llm.response.cost`
key never surfaced in the trace list. Now emits both keys (canonical +
legacy) so renderers + any existing consumers both work.

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

* fix(arize): keep span.kind=LLM for tool-using completions + render tool_calls in Output

A chat completion that passes `tools=[...]` or returns `tool_calls` is still
an LLM call per the OpenInference spec — TOOL is reserved for actual tool
execution. The previous override demoted these to TOOL, breaking Arize's
LLM-scoped dashboards/evals and skewing token/cost analytics for any
tool-using traffic.

Additionally, when an assistant response had no text content but did
request tool calls, `output.value` was set to the empty string so Arize's
"Output" pane rendered blank. Now serializes the tool_calls into a compact
JSON summary in `output.value` (the structured `MESSAGE_TOOL_CALLS.*`
attributes are still emitted unchanged).

Cleanups:
  - extract `_get_tool_calls` and `_normalize_tool_call` helpers,
    deduplicating the dict-vs-Pydantic + function-dict logic across
    `_set_choice_outputs`, `_emit_message_tool_calls`, and the new
    `_summarize_tool_calls_for_output`.
  - drop redundant late `OPENINFERENCE_SPAN_KIND` write — the defensive
    early write is now the single source of truth.
  - remove a dead local re-import of `MessageAttributes`/`SpanAttributes`.

Tests: 73 pass (added regression guard asserting span.kind stays LLM for
completions that pass tools AND return tool_calls; existing call_count
assertion restored to 26).

* chore(arize): tighten cleanup — fold _get_tool_calls into _safe_get

Two tiny cleanups, no behavior change:
- collapse `_get_tool_calls` to use `_safe_get`, removing a 7-line
  hand-rolled dict-vs-attribute fallback that duplicated existing logic.
- trim the `_set_choice_outputs` tool-call summary comment from 4 lines
  to 2 (was over-explaining).

* fix(arize): address Greptile review — drop session_id=trace_id fallback, remove dead code, fix Black

Three Greptile-flagged issues + the Black formatting CI failure.

1. SESSION_ID no longer falls back to trace_id. Previously every span
   without an explicit `user_api_key_end_user_id` would have its
   session.id set to the per-request trace_id, which creates one
   distinct "session" per request and breaks Arize's Session-grouping
   analytics. Now SESSION_ID is emitted only when an explicit end-user
   identifier exists, and the trace_id is emitted under its own
   `litellm.trace_id` key so spans remain filterable by trace.

2. Removed dead `ArizeOTELAttributes.set_response_output_messages`
   override. Confirmed zero callers in the entire repo (the live path
   is `_set_choice_outputs` via `_set_response_attributes`). The
   override was preexisting dead code, but the expansion of
   `_set_choice_outputs` in this PR made the divergence misleading.

3. Removed permanently-dead first branch in cache_write detection.
   `_safe_get(prompt_token_details, "cache_creation_tokens")` looks
   for a key that neither OpenAI's `prompt_tokens_details` nor
   Anthropic's payload ever exposes. Now reads straight off `usage`
   for `cache_creation_input_tokens`.

4. Reformatted both files under Black 26.3.1 (the version CI uses
   via `uv sync --frozen`). Local previously used 24.10.0.

Tests: 74/74 pass in the arize suite (added
`test_arize_does_not_use_trace_id_as_session_id_fallback`).
Combined arize + opentelemetry suite: 295/295 pass.

End-to-end verified live: tool-call still emits `span.kind=LLM` and
JSON tool_calls in `output.value`; `session.id` is now correctly
unset when no end_user_id is provided; `litellm.trace_id` is
populated; Bedrock passthrough input/output unchanged.

* fix(arize): gate passthrough prompt export on message redaction

- Skip the complete_input_dict bridge in _maybe_normalize_passthrough when
  should_redact_message_logging() is true, so enabling redaction no longer
  leaks raw passthrough prompts into Arize (Veria security finding).
- Split passthrough input/output rendering into helpers to satisfy PLR0915.
- Remove dead call_type assignment (F841).

Validated live against a Bedrock passthrough proxy exporting to Arize:
non-redacted renders the real prompt on litellm_request; global
turn_off_message_logging yields input.value=redacted-by-litellm with the
raw_gen_ai_request child span suppressed and no SSN/marker leakage.

Litellm websocket improvements (#29563)
* Add support for websocket via codex

* Add model alias and creds support

* fix: skip cost tracking for WS session wrapper call types

The @client decorator on _aresponses_websocket fires async_success_handler
with result=None after the session ends. This triggered cost tracking errors
because standard_logging_object is never built for None results.

Per-turn costs are correctly tracked by individual litellm.aresponses calls
inside the session. The outer session-level logging obj should not attempt
cost tracking.

Fix: skip _aresponses_websocket and _arealtime call types in deployment_callback_on_success,
RouterBudgetLimiting.async_log_success_event, and _PROXY_track_cost_callback.

* fix: address Greptile review comments

Fix JSON injection: use json.dumps instead of f-string interpolation for model name in WS body.

Add 30s timeout for first WS frame to prevent unbounded connection resource tie-up.

Restore per-event model override in streaming_iterator; fall back to connection-level model when event omits it.

Strengthen regression test: inject alias into kwargs via _update_kwargs_with_deployment mock so the test would fail on un-fixed code.

* fix: handle nested response.create format in first-frame model extraction

When ?model= is omitted, the first WS frame can carry the model in either flat
format (first_event["model"]) or nested format (first_event["response"]["model"]).
The flat-only check would silently reject clients using the nested wire format.

Mirrors the same two-format logic in _build_base_call_kwargs.

* fix: don't force connection-level custom_llm_provider on per-event model overrides

If a client sends a different model per response.create turn, litellm needs to
re-resolve the provider from that model string. Forcing the connection-level
custom_llm_provider would silently route the request to the wrong backend.

Only inject custom_llm_provider when the per-event model matches the
connection-level model.

* refactor: extract WS model extraction into testable function

Pull the flat/nested model extraction into _extract_model_from_first_ws_event
so tests import and exercise the real function rather than a copy.

* fix: compare providers not full model strings in _inject_credentials

The model == self.model guard was too strict: same-provider model variants
(e.g., vertex_ai/gemini-2.0 -> vertex_ai/gemini-1.5 on one connection) would
lose custom_llm_provider, breaking routing when a custom api_base is in use.

Compare the provider extracted by get_llm_provider instead, so same-provider
variants still inherit the connection-level provider while cross-provider
overrides let litellm re-resolve.

* style: black formatting

* refactor: extract first-frame model resolution to fix PLR0915 (too many statements)

* Fix responses WebSocket first-frame validation

* fix: classify WS first-frame read errors and clarify cost-skip log

Distinguish client disconnects from server errors when reading the
responses WebSocket first frame, make the cost-tracking skip log message
accurate for session wrappers (which do carry a model), and resolve the
connection-level provider once per session instead of on every
response.create event.

* test: cover WS first-frame read errors and same-provider credential injection

Adds regression tests for the still-uncovered responses WebSocket paths:
the timeout, invalid-JSON and missing-model branches of
_read_ws_model_from_first_frame, plus the provider comparison in
ManagedResponsesWebSocketHandler._same_provider and _inject_credentials
(same-provider model variants keep the connection provider; cross-provider
models re-resolve).

* fix(responses-ws): fall back to explicit custom_llm_provider when connection model is unresolvable

When a WebSocket session is opened with a custom deployment alias that litellm
cannot resolve to a provider, _connection_provider was None, so _same_provider
returned False for every resolvable per-event model and the connection-level
custom_llm_provider was dropped. Use the explicitly-set custom_llm_provider as
the connection provider in that case so same-provider per-event models still
inherit it while genuinely cross-provider models continue to re-resolve.

fix(vertex): strip output_config.effort for Vertex Claude models that reject it (Haiku 4.5) (#29585)
* fix(vertex): strip output_config.effort for models that reject it

Haiku 4.5 on Vertex AI does not support output_config.effort and 400s with
"output_config.effort: Extra inputs are not permitted". PR #27074 emptied
VERTEX_UNSUPPORTED_OUTPUT_CONFIG_KEYS so effort would forward for Opus/Sonnet
4.6+, but that made the strip unconditional across every Vertex Anthropic
model, including ones that don't support it. Claude Code injects effort into
its default Messages payload, so `claude --model claude-haiku-4.5` started
failing.

Make the sanitizer model-aware: drop output_config.effort for models that
don't advertise output_config support (or any reasoning effort level) while
forwarding it for those that do. The fix covers both the chat-completion and
Messages pass-through transformation paths since they share the helper.

* chore(vertex): log at debug when dropping unsupported output_config.effort

Operators pointing an unregistered Vertex Claude alias that does support
effort would otherwise see it stripped with no signal. Debug level keeps it
out of normal logs since Claude Code sends effort on every request.

ci: reproduce default-Windows wheel install to guard MAX_PATH (#29597)
* ci: reproduce default-Windows wheel install to guard MAX_PATH

The existing using_litellm_on_windows job installs the project with
`uv sync`, an editable source install that never copies package files
into a deep site-packages path, so it cannot see the 260-char MAX_PATH
overflow that breaks `pip install litellm` on default Windows. The
content-filter benchmark fixtures have hit that limit three times
(#21941, #22039, #29536), each caught only after release.

This adds a guard to the same job that builds the wheel and installs it
the way an end user would: into a venv whose site-packages prefix is
padded to a realistic worst-case Windows length (~100 chars), then
asserts the install completes and litellm imports. Any packaged path
long enough to bust MAX_PATH at that prefix is reported up front, so the
check is deterministic regardless of the runner's long-path setting,
while the real install also covers failure modes a length heuristic
cannot (half-unpacked packages, reserved names, case collisions).

This commit is the guard only; on the current tree it correctly fails
because nine fixtures still exceed the limit. The rename that brings
them back under it follows on this branch.

* fix(packaging): shorten content-filter benchmark fixtures under MAX_PATH

The 10 content-filter benchmark result fixtures used the legacy
block_{topic}_-_contentfilter_({yaml}).json naming, up to 176 chars
inside the wheel, which busts the Windows 260-char MAX_PATH limit once
extracted under a realistic site-packages prefix and aborts
`pip install litellm` on default Windows.

Rename them to the short {topic}_cf.json scheme that
_save_confusion_results already emits today (it splits the label on the
em-dash and writes f"{topic}_cf"), matching the insults_cf.json and
investment_cf.json files fixed earlier. Re-running the eval suite now
regenerates these same short names rather than recreating the long ones.

This drops the longest packaged path from 176 to 128, so the guard added
in the previous commit goes from red to green with a 32-char margin.

* test(windows): tidy MAX_PATH guard per review

Close the wheel zip via a context manager rather than leaning on
refcount collection, and select the wheel under dist/ by newest mtime so
a stale artifact from an earlier build cannot be tested instead of the
one just produced. Also pin down the venv-depth formula with a short
note: the +2 is the separator joining the venv root to "Lib" plus the
trailing separator before the entry, which lands the simulated
site-packages prefix at exactly 100 chars.

fix(anthropic/adapter): emit thinking block for reasoning_content-only streaming chunks (#29600)
* fix(anthropic/adapter): open thinking block for reasoning_content-only streaming chunks

The /v1/messages streaming content-block classifier (_translate_streaming_openai_chunk_to_anthropic_content_block) only recognized thinking_blocks. OpenAI-compatible reasoning backends (vLLM/SGLang reasoning parsers: DeepSeek-R1, Qwen3, gpt-oss, ...) populate reasoning_content with thinking_blocks=None, so the classifier fell through to a text block. The delta translator already emits thinking_delta for reasoning_content, so those deltas landed inside a text block and Anthropic streaming clients (Claude Code, SDK .stream()) silently dropped the chain-of-thought.

Mirror the reasoning_content fallback already present in the non-stream translator and the streaming delta translator so the classifier opens a thinking block. Adds a focused regression test.

* fix(anthropic/adapter): reach reasoning_content branch when thinking_blocks attr is absent

Delta deletes the thinking_blocks attribute when unset, so the prior nested check was unreachable for reasoning-only chunks (vLLM/SGLang). Make it a sibling elif so the content block is classified as thinking.

* test(proxy): stop component-allowlist test leaking DATABASE_URL into xdist peers

The component-allowlist test pins throwaway DATABASE_URL/LITELLM_MASTER_KEY
values at import time via os.environ so importing proxy_server doesn't need a
live database. Those values persisted for the whole pytest-xdist worker, so a
sibling test sharing the worker (test_key_rotation_e2e's DB-backed E2E case)
saw the leaked sqlite DATABASE_URL, treated it as an available database instead
of skipping, and the Prisma engine rejected the non-postgres URL (P1012 ->
httpx.ConnectError). Restore the prior environment after the import so the
throwaway values never escape the module.

Fix : a2a bugs 030626 (#29566)
* Fix error code and context id injection bug

* Add support for all A2A methods

* Add logging

* address greptile review: relay upstream JSON-RPC errors, move _PASCAL_TO_WIRE to module level, add error path tests

* fix(a2a): run pre_call_hook for tasks/resubscribe SSE path to enforce guardrails

tasks/resubscribe was returning the raw SSE stream without calling proxy_logging_obj.pre_call_hook, silently bypassing any guardrails configured on the agent. This patch calls pre_call_hook before streaming begins and wires post_call_failure_hook into the SSE generator so errors are logged. Adds a regression test verifying the hook is called.

* fix(a2a): use get_async_httpx_client instead of creating httpx clients per request

Creating httpx.AsyncClient instances per-request adds ~500ms latency. Switch _forward_jsonrpc and _forward_jsonrpc_sse to use the shared client from get_async_httpx_client(httpxSpecialProvider.A2A).

* fix(a2a): forward caller identity headers on task ops; validate push notification URL

Two security fixes for task management methods:

1. All task operations (tasks/get, tasks/list, tasks/cancel, tasks/resubscribe, push notification config methods) now forward X-LiteLLM-User-Id and X-LiteLLM-Team-Id headers to the upstream agent, so the agent can scope task access to the authenticated caller.

2. tasks/pushNotificationConfig/set validates the callback URL before forwarding: requires HTTPS and rejects private/loopback/reserved IP ranges and localhost hostnames to prevent SSRF.

* Fix A2A task hook and push URL handling

* fix(a2a): fix mypy type errors for request_id and header_name dict key types

* Fix A2A request id and params forwarding

* Forward trace IDs for A2A task calls

* fix(a2a): strip client-forwarded X-LiteLLM-* headers before applying authenticated identity

A client could send x-a2a-<agent>-x-litellm-user-id in their request and have it forwarded to the upstream agent as an authenticated identity header. Fix: sanitize any X-LiteLLM-* headers from agent_extra_headers before merging, then apply the authenticated identity headers last so they always override client-supplied values.

* Fix A2A SSE fallback JSON-RPC error code

* Fix A2A SSE error id backfill

* fix(a2a): validate both push notification url fields to close SSRF bypass

* fix(a2a): widen request_id annotation to match JSON-RPC id call sites

* fix(a2a): run post-call streaming hook for tasks/resubscribe so agent guardrails apply

tasks/resubscribe returned the raw upstream SSE stream without routing events
through the post-call streaming hook, so output guardrails configured on the
agent were silently skipped for streaming task subscriptions while every other
task method and message/stream applied them. Parse upstream JSON-RPC SSE events
and feed them through async_streaming_data_generator, matching message/stream,
so guardrails inspect the streamed task content. Adds a regression test that
fails when the streamed events bypass the guardrail hook.

Litellm oss staging 030626 (#29578)
* Fix incorrect agent API request example payload structure (#29556)

* fix(otel): add litellm_metadata fallback in _get_span_context and _end_proxy_span_from_kwargs (#29427)

* fix(otel): add litellm_metadata fallback in _get_span_context and _end_proxy_span_from_kwargs

On /v1/messages and other LITELLM_METADATA_ROUTES, the parent OTel span
is stored in litellm_params['litellm_metadata'] instead of
litellm_params['metadata']. When the request body contains a native
'metadata' field (e.g. Anthropic's {"user_id": "..."}),
litellm_params['metadata'] gets overwritten and the parent span is lost,
producing orphan root spans with a different trace_id.

Add fallback checks to litellm_metadata in:
- _get_span_context(): so child spans find the correct parent
- _end_proxy_span_from_kwargs(): so the proxy span gets closed

Fixes: https://github.com/BerriAI/litellm/issues/27934

* test(otel): tighten assertions per Greptile review

- test_span_context_metadata_takes_priority: assert litellm_metadata
  span is never accessed, proving metadata takes priority
- test_span_context_no_parent_when_neither_has_span: assert both ctx
  and detected_span are None

* fix: remove premature end-user budget check from get_end_user_object (#29420)

* fix(proxy): remove premature end-user budget check from get_end_user_object

Problem:
- `_check_end_user_budget()` was called inside `get_end_user_object()`
- This caused budget checks to run BEFORE `skip_budget_checks` could be evaluated
- Zero-cost models (e.g., local vLLM) were incorrectly blocked when
  end-users exceeded their budget, even though they should bypass budget checks

Solution:
- Remove `_check_end_user_budget()` calls from `get_end_user_object()`
- Budget enforcement now happens exclusively in `common_checks()` where
  `skip_budget_checks` context is available
- `get_end_user_object()` keeps `route` as optional in function parameter for backwards compatibility and future implementation.

* refactor(tests): update budget enforcement tests to reflect changes in get_end_user_object

- test_get_end_user_object() verifies data fetching
- test_check_end_user_budget() verifies enforcement
- test_budget_enforcement_blocks_over_budget_users() integrates _check_end_user_budget()
- test_resolve_end_user_reraises_budget_exceeded() is now test_resolve_end_user since no budget exceeded is thrown in get_end_user_object()

* fix(vertex/gemini): keep tool_call reference when a text-only assistant message follows (#29561)

`_gemini_convert_messages_with_history` tracks `last_message_with_tool_calls`
so a following tool result can be matched back to its tool call. The assignment
was inside a branch guarded by
`assistant_msg.get("tool_calls", []) is not None`, which is also True for a
text-only assistant message (an empty list is not None). As a result, an
assistant message with no tool calls that appears between a tool call and its
tool result overwrote the reference, and conversion failed with:

    Exception: Missing corresponding tool call for tool response message.

This shape is common: a model emits a short narration/assistant message after a
tool call before the tool result is appended.

Only update `last_message_with_tool_calls` when the assistant message actually
carries tool_calls (or a function_call). Adds a regression test.

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505) (#28575)

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505)

When a Chat Completions request to a GPT-5.4+ model contains both
`tools` and `reasoning_effort`, `completion()` auto-routes through
`responses_api_bridge`. The bridge handler called
`litellm.responses()` / `litellm.aresponses()` without forwarding the
already-resolved `custom_llm_provider`, so the downstream call
re-invoked `get_llm_provider()` with `custom_llm_provider=None` and
stripped a second provider prefix from a `provider/provider/model`
deployment string.

For a deployment configured as `openai/openai/openai/gpt-5.5`,
the bridge flow sent `openai/gpt-5.5` to the upstream API instead of
the correct `openai/openai/gpt-5.5`. Upstream APIs that enforce
model-name allow-lists rejected this as `key_model_access_denied`.

Fix: pass the locally-resolved `custom_llm_provider` into both the
sync `responses()` and async `aresponses()` calls so the downstream
`_resolve_model_provider_for_responses` sees an explicit provider
and skips the second prefix-strip.

New regression test
`tests/test_litellm/completion_extras/test_responses_bridge_provider_propagation.py`
pins both call sites: each must forward `custom_llm_provider`.

* fix(28505): set custom_llm_provider on request_data instead of as duplicate kwarg

Greptile flagged that the previous patch passed custom_llm_provider as an
explicit kwarg to responses()/aresponses() while request_data already
carried it via the spread of sanitized_litellm_params, which would raise
TypeError: got multiple values for keyword argument on every real bridge
call.

Switches to assigning request_data['custom_llm_provider'] before the call
so the resolved provider wins over whatever sanitized_litellm_params spread
in, without duplicating the kwarg.

Updates the regression test to seed request_data with a sentinel
custom_llm_provider so it actually exercises the overwrite path (the
previous test mocked transform_request with a minimal dict and never hit
the conflict).

* Add 1-hour cache write pricing for EU/AU/JP Bedrock Anthropic models

The 1-hour prompt-cache write tier
(`cache_creation_input_token_cost_above_1hr`) was added to the
us./global. variants of the Claude 4.5/4.6/4.7 family on Bedrock, but
the eu./au./jp. cross-region inference profiles were left without it.
AWS Bedrock pricing applies the same +10% regional premium across all
geo profiles, so eu./au./jp. should carry the same 1-hour rates as
us. (1.6x the 5-minute regional rate).

Without these fields, cost tracking on EU/AU/JP Bedrock 1-hour-TTL
prompt caching falls back to the 5-minute write rate and undercounts
spend by ~60% for European, Australian, and Japanese tenants.

Adds the 1-hour tier (and Sonnet 4.5's long-context >200K tier where
AWS publishes one) to 14 regional Bedrock entries in both
`model_prices_and_context_window.json` and the bundled
`model_prices_and_context_window_backup.json`:

  - eu./au.   Opus 4.6     ($11.00 / MTok)
  - eu./au.   Opus 4.7     ($11.00 / MTok)
  - eu./au./jp. Sonnet 4.6 ($6.60 / MTok)
  - eu./au./jp. Sonnet 4.5 ($6.60 / MTok regular, $13.20 / MTok LC)
  - eu./au./jp. Haiku 4.5  ($2.20 / MTok)

Also extends `tests/test_litellm/test_bedrock_anthropic_1hr_cache_pricing.py`
with a `REGIONAL_EXPECTED` parametrized block covering all 13 new
entries plus the existing 1.6x ratio invariant.

Note: `eu.anthropic.claude-opus-4-5-20251101-v1:0` carries the
wrong 5m rate today (base 6.25e-06 instead of regional 6.875e-06),
which would break the 1.6x ratio check. It is intentionally left out
of this PR so the scope stays "1-hour cache tier addition" — a
separate follow-up should correct the EU 5m rates for Opus 4.5.

* Add 1-hour cache write pricing tier for Vertex AI Anthropic models

GCP Vertex AI publishes a separate 1-hour cache write column for the
Claude family (1.6x the 5-minute write rate, matching the documented
Bedrock ratio). LiteLLM's Vertex AI Anthropic entries only carry the
5-minute tier, so any request that uses `cache_control: {"ttl": "1h"}`
on Vertex AI Claude is undercounted in cost tracking by ~60%.

The runtime side already supports the 1-hour tier — `VertexAIAnthropicConfig`
extends `AnthropicConfig`, populating `ephemeral_1h_input_tokens`, and
`_calculate_cache_creation_cost` reads `cache_creation_input_token_cost_above_1hr`.
Only the price registry was missing data.

Adds the field to 19 vertex_ai/claude-* entries across both
`model_prices_and_context_window.json` and the bundled
`model_prices_and_context_window_backup.json`:

  - Haiku 4.5 ($1.25 -> $2.00 / MTok)
  - Sonnet 3.7 / 4 / 4.5 / 4.6 ($3.75 -> $6.00 / MTok)
  - Opus 4.5 / 4.6 / 4.7 ($6.25 -> $10.00 / MTok)
  - Opus 4 / 4.1 ($18.75 -> $30.00 / MTok)

Adds `tests/test_litellm/test_vertex_anthropic_1hr_cache_pricing.py`
mirroring the Bedrock equivalent — pins each (5m, 1h) pair per model
and asserts the 1.6x ratio across the family.

Fixes #27781.

* address greptile review: add _transform_image_usage method and model-map supports_image_size flag

- Add _transform_image_usage instance method to GoogleImageGenConfig that
  delegates to transform_gemini_image_usage, fixing the regression test
- Replace hardcoded "2.5-flash" string check in supports_gemini_image_size
  with a get_model_info lookup on supports_image_size (default true)
- Add supports_image_size: false to all gemini-2.5-flash model entries in
  model_prices_and_context_window.json so capability is controlled via the
  model map rather than embedded in code

* fix test failures: schema validation, mypy type, model info plumbing, pricing test

- Add supports_image_size to ModelInfoBase TypedDict so get_model_info surfaces it
- Pass supports_image_size through _get_model_info_helper constructor call
- Fix supports_gemini_image_size to use value is not False (None means unset, defaults to True)
- Add supports_image_size to JSON schema in test_aaamodel_prices_and_context_window_json_is_valid
- Correct gemini-3.1-flash-lite pricing assertions in test to match JSON values

* Add Azure AI Kimi K2.6 metadata (#27052)

* Add Azure AI Kimi K2.6 metadata

* Scope Kimi metadata test cost map setup

* fall back to substring check for models not in model_prices_and_context_window.json

Models like gemini-2.5-flash-image-preview are not in the pricing JSON,
so get_model_info raises. Fall back to "2.5-flash" not in model when the
JSON has no explicit supports_image_size entry for the model.

* fix(inception): don't forward global litellm.api_key to Inception FIM

Match the Inception chat config: resolve only an Inception-specific key
(param, litellm.inception_key, or INCEPTION_API_KEY) for the text-completion
FIM path. The global litellm.api_key (often an OpenAI key) was both leaking
to api.inceptionlabs.ai and taking precedence over the configured Inception
key when set.

* fix(auth): enforce end-user budget on custom-auth path that skips common_checks

get_end_user_object() no longer raises BudgetExceededError, so custom-auth
deployments with custom_auth_run_common_checks unset (which skip the
centralized common_checks gate) stopped enforcing the end-user budget,
letting an over-budget end user keep making requests. Re-enforce the
budget in _run_post_custom_auth_checks on that path.
