refactor(rust_bridge): route every Rust-to-Python call through host modules (#50822)
* refactor(rust_bridge): route every Rust-to-Python call through host modules

Rust now reaches Python only through litellm/rust_bridge/host/ (plus the
execution driver), and no Python module outside host/ imports it. Library
calls that reproduce Python behavior (httpx and OSError error text,
huggingface_hub downloads, the random generator, os.environ) go through
host functions too. The rule is written into host/AGENTS.md

The live litellm.model_cost table, its version and every Python writer move
to litellm_core_utils/model_cost_table.py, and host/model_cost.py keeps only
the functions Rust calls. The cost map fetch passes use_http_settings instead
of handing Rust an http_settings() snapshot

* refactor(rust_bridge): read REDIS_USERNAME from the process environment in Rust

The Redis bridge asked Python for all of os.environ to read one key. CPython's
os.environ writes through to the process environment, so Rust reads it with
ProcessEnvironment like the rest of the module. Also drops doc comments that
restated their code.

test(integration): recognize the model list's lock in the held write helper (#50974)
The registry lock fix (#50933) makes add_deployment and set_model_list wait
for a held delete on the same lock, taken inside HostedModelList as
self._lock. The helper only knew lines spelled with
self._deployment_index_lock, so it never saw those two writes reach the lock
and timed out after 10 seconds.

test(integration): empty the shared client cache before the tier pin batch test (#50854)
The test stores its recording Redis client in litellm's shared client
cache with the default ttl. When earlier tests in the same process have
filled that cache with longer lived clients, the next insert evicts the
recording client, the pin is read through a fresh client, and the test
sees no commands on the wire.

refactor(model-cost): move the cost map inputs, fetch and register_model overlay into Rust (#50501)
* refactor(model-cost): move the cost map inputs, fetch and register_model overlay into Rust

* fix(model-cost): keep main's compat helpers pure and move network tests to integration

ModelCostMapReloaded.model_cost_map now returns the alias-sharing table, so an alias registration after adopting a reload still reprices the owner. _finalize_model_cost_map reads a caller's map without size limits and installs nothing, through the new NativeModelCostMap.finalize. The unit tests that started a local server or a child interpreter now live in tests/integration/sdk/test_model_cost_fetch_sdk.py, and run_isolated gets direct tests for joining its blocking pool and leaving the fork gate alone.

test(integration): repair tests that merged changes left stale (#50782)
Several integration tests on main still assert behavior that later changes replaced on purpose, so they fail on every scheduled run, and one of them stops the whole sdk group at import.

The batch cost case expected cached tokens to bill at the Batch input price when a price row has no Batch cache price. Since #50062 they bill at the Standard cache price, so the case now expects 0.000235 input cost and is renamed to say so.

The OTel v2 attribute test pinned langfuse_otel and langtrace as carrying no request metadata baggage. Since #50373 every OTel v2 destination carries it, so all seven callbacks share one expectation and the Langfuse baggage test that was deferred under LIT-9128 runs again.

The clean-EOF outage test trips its database relay on the text of the spend log insert. The ledger writes that insert without the "public" schema prefix, so the relay never tripped and the test timed out before it checked anything. The trigger now matches the insert on both write paths.

The usage routing tests expected cooldown, tpm and rpm keys in one MGET. Since #50170 the cooldown keys are read in their own MGET, at most once per DEFAULT_COOLDOWN_REDIS_READ_INTERVAL_SECONDS. Both the proxy and the SDK test now expect the two MGETs, and the proxy test waits out that interval after its /model/info poll, which reads the same keys.

The concurrent deployment delete test held its writer inside Router._update_deployment_indices_after_removal, which went away with the Python router core in #50178, so the file failed at import and stopped the whole sdk group. It now holds the writer where the registry reads the model list again after router-core applied the change.

test(router): expect no fallback errors header for non-bool include_fallback_errors (#50259)
The Rust core reports fallback errors only when include_fallback_errors is
literally true. The routing and SDK wire tests still expected the header for
truthy non-bool values (1 and a 5 KB string), which the deleted Python core
produced by accident. Every non-bool value now expects no errors, and the
flag still must not reach the provider.

fix(bedrock)!: keep Claude's thinking when response_format json_schema is set (#49696)
* fix(anthropic): stop forcing the response_format json tool when Claude will think

A forced tool call skips Claude's thinking. The json_schema emulation forced
json_tool_call unless thinking.type was enabled, so adaptive thinking and the
models that think by default (Opus 5, Sonnet 5, Haiku 5.5, and the always-on
families) lost their thinking on every structured-output request.

AnthropicModelInfo.response_format_tool_can_be_forced is now the one check
the Anthropic, Bedrock Converse (including the native output fallback) and
Databricks paths use. It leaves the tool unforced when thinking is requested
in any form or the model thinks by default, and keeps forcing it when the
request turns thinking off (thinking disabled or reasoning_effort none) on a
model that accepts forced tools.

The new thinking_on_by_default cost map key marks Opus 5, Sonnet 5 and
Haiku 5.5 on the providers that reach these paths, and a miss-only fallback
rule covers unmapped Claude 5 and later ids.

* fix(bedrock): route native output and thinking token counts by whether Claude will think

Bedrock's native output opt-in now uses the same will-think check as the json tool, so Claude 5 models that think by default with no thinking param go native. Converse also asks for /usage/output_tokens_details on those models, so reasoning tokens are reported for them.

* fix(anthropic): tell Claude to answer through the unforced response_format tool

Moves the integration tests that check the forced JSON tool from Claude 5 models to Opus 4.8, since Claude 5 models now keep their default thinking and take the unforced tool or native output

* fix(anthropic): keep open-object schemas on the json tool when Claude will think

Native output closes every object, so an open object came back empty. Also declare thinking_on_by_default in the Rust model catalog and expect the Converse thinking-token field in test_main

* fix(anthropic): hold streamed prose until the JSON tool decides the answer

In json mode with the unforced JSON tool, Claude can write its working before it calls the tool. The stream now holds that text, drops it when the JSON tool answers, and sends it when Claude calls a caller tool or skips the JSON tool, matching the non-streamed reply.

* test(anthropic): build the stream test events without nested comprehensions

* fix(anthropic): keep always-on thinking models unforced, open objects native when thinking, and the tool instruction Claude-only

* test(anthropic): keep main's open-object integration cases and cover the unforced tool on a default-thinking model

* fix(anthropic): treat thinking False as thinking off so the JSON tool stays forced

Cover thinking False on the Anthropic and Converse forcing tests, and pin that a Converse
json_schema stream with the unforced JSON tool never sends Claude's working text as content

* fix(anthropic): drop the thinking False forcing case that completion never reaches

litellm.completion turns thinking False into no thinking param before any route sees it,
so the case was dead on the request path and False keeps meaning the model's default

* test(bedrock): collect the Converse json_schema stream chunks in one assignment

* fix(typing): avoid Final declarations inside transcription cost loop

* refactor(audio): reuse transcription mapping and duration resolution

* fix(realtime): enforce model budgets and preserve translation routing

* fix(audio): log streamed transcripts whose done event reports detected languages

* fix(audio): pass stream, languages and keywords through unchecked for non-OpenAI transcription providers

Providers without a streaming transcription handler got UnsupportedParamsError
for stream=True, languages and keywords, where the merge base forwarded them as
provider-specific params. Only openai and azure validate them now.

* fix(audio): bill streamed gpt-transcribe from the provider's reported duration

The stream path computed cost after logging had replaced the transcription's
duration usage, so it fell back to the measured file length while the
unstreamed call billed the provider's seconds.

* fix(transcription): log streamed transcription usage from the provider response

The stream logging path built the spend payload from the response after
its duration usage was transformed away, so whisper-1 with stream=true and
streamed gpt-transcribe logged an empty usage object. Bill and log from the
provider's TranscriptionResponse in both the sync and async paths.

* fix(realtime): keep main's routing, protocol and transport behavior around the new translation routes

- Send OpenAI realtime and translation client_secrets and calls through litellm's httpx client again, so ssl_verify and custom CA settings apply and upstream errors keep main's shape
- Use the input transcription model as the session model only for transcription sessions
- Drop the new /openai/v1 translation aliases and record each lazy feature's own routes, so the /openai pass-through and the MCP routes resolve as on main
- Let a configured Azure realtime_protocol win for every model, with GA as the default only when none is set
- Return x-litellm headers on streamed transcriptions and mark the request done
- Refuse translation sessions before connecting upstream when realtime guardrails apply or the provider is not OpenAI or Azure
- Accept json and text for gpt-transcribe, and drop other formats under drop_params instead of failing
- Bill translation sessions on output audio seconds only, at the single published rate
- Document the 201 SDP answer on the translation calls routes and the transcription 200 response

* fix(realtime): restore main behavior for guardrails, Azure transcription, and realtime clients

Streamed transcription runs unstreamed when a deployment post_call guardrail applies, so the
guardrail still sees the transcript. Azure transcription maps v1, latest and preview to the
default dated version on the deployments route for every model. The SDK client secret keeps
session.model ahead of model, realtime WebSockets connect to api_base again, realtime metadata
keeps only guardrails, and managed agents need an explicit transcription model. Reverts the two
unrelated streamed Responses error codes and the duplicate cached_tokens_details field, and the
gpt-transcribe format check only reads the request provider's cost map entry.

* fix(realtime): keep main's transcription, client secret and route behavior where the PR changed it

Transcription reaches every provider as on main again, sends stream only when asked, forwards language and
languages together, keeps form key order, bills provider seconds only when above zero, honors base_model for the
new flags, keeps main's Azure api_version on the proxy path, and streams carry chat's headers, an error event on a
mid-stream failure, and a spend row when the stream ends early. Translation cost reads both per-second rates from
one source and spend rows carry the billed seconds.

Realtime transcription WebSockets keep model in the upstream URL outside OpenAI's hosts, client secrets forward
explicit nulls, accept conversation and delay, and answer 400 on a malformed body, the /openai translation paths
are back to main, translation refuses only for guardrails realtime sessions run, nested aliases resolve and later
session.update models are authorized, translation client secrets run per-model auth, beta clients bridged to GA
get beta-shaped session events, and transcription sessions send the deployment model in both shapes.

* fix(realtime): address review findings on transcription billing, streaming and realtime auth

Per-second pricing replaces token billing only when the priced entry sets no token rates, translation rates fall back per key to the cost map, transcription cache keys include languages and keywords, a stream request a post_call guardrail forces unstreamed comes back as redacted SSE, Azure beta clients are bridged only for GA-only deployments, nested transcription models on the realtime WebSocket are checked against the key, and translation spend carries key and team metadata

* fix(azure): pick the GA realtime protocol for deployments whose model_info.base_model is GA-only

* fix(realtime): preserve prior merge resolutions after rebase

* fix(realtime): enforce translation policies and normalize Azure transcription URLs

* fix(cookbook): stop translation once output idles after the upload ends

* fix(realtime): bill translation on input audio and drop pre-read stream cost headers

Translation spend now uses the input audio seconds the session sent, priced
through input_cost_per_second, instead of the translated output duration.
A streamed transcription no longer returns cost headers before the stream is
read, since the cost is only known after the last event. Also removes an
unused realtime guardrail helper.

* fix(realtime): drop top-level session nulls, bill dropped transcription streams, and bridge beta response fields

Client secret, translation and transcription session bodies drop top-level nulls again, as main did, while nested nulls such as turn_detection still pass through. Transcription client secrets send the deployment model as session.model. A streamed transcription the client drops still runs its success callbacks, and the stream ends with data: [DONE] like OpenAI's. The beta to GA bridge maps max_response_output_tokens, speed and noise reduction, remaps response.create, and drops temperature under drop_params. The Entra token for realtime HTTP routes is fetched off the event loop

* test(e2e): cover realtime translation, live transcription, client secrets, and streamed transcription

* fix(realtime): close review gaps in translation billing, transcription streams, and Azure GA

Bill translation sessions from the deployment's own per-second rates, add per-second prices for
Azure gpt-4o transcribe models, keep stream-scoped guardrails seeing the caller's stream flag, map
mid-stream transcription errors to LiteLLM exceptions with a [DONE] frame, map GA responses back to
the beta shape for bridged beta clients, honor the minting key's guardrail opt-out on translation
calls, restore the Azure transcription session URL, and flag GA-only Azure realtime models

* fix(realtime): bill a translation rate the deployment omits from the session model

* test(e2e): check translated speech is not English instead of exact French wording

* fix(realtime): keep main's behavior for non-bridged backends, stream error frames, gateway URLs and Azure transcribe prices

Remap beta events to GA only for bridged beta clients and translation sessions, bridge beta clients on GA-pinned Azure deployments, log error-only upstream sessions as failures, flag dated Azure GA realtime models, drop the unpublished Azure per-second transcribe rates, log a mid-stream transcription failure once, keep main's SSE error frame outside transcription, drop unsupported transcription params under drop_params, keep the caller's Azure auth headers, keep a gateway /v1 path, let key opt-outs release string-callback guardrails on translation, and keep the cookbook waiting while a long upload is still sending

* fix(realtime): keep the proxy's realtime session gate off translation sessions

A key that opts out of a legacy callback guardrail now gets a working translation session, since the transcription-guardrail gate no longer sends a realtime session.update the translation upstream rejects

* fix(realtime): keep websocket model limits, bill measured transcription length, route transcription sessions on the allowed model

A WebSocket opened without a query model now authorizes as an empty model, transcription cost prefers the measured upload length over the provider's reported seconds, transcription sessions overwrite nested models with the authorized top-level model again, and a non-boolean transcription stream value answers 400 or is dropped under drop_params.

* fix(ci): copy the rust bridge extension into the openapi docs gate's base worktree

* fix(model-catalog): accept the realtime translation endpoints in the cost map

* fix(cookbook): close the translation session and read until session.closed

* fix(realtime): treat an empty transcription stream as unset and pass the cost-map guard

An empty `stream` form value runs the transcription unstreamed again, as
OpenAI does, instead of answering 400. The four translate cost-map entries
drop the translation routes from supported_endpoints until the main
branch's catalog parser accepts them, and the nested transcription model
lookup uses the router registry entry point.

* test(proxy): drop the mid-stream error frame pin that main's error shape change replaced

* fix(transcription): bill uploaded seconds when a stream fails mid-transcript

* fix(proxy): bill uploaded seconds when a streamed transcription breaks mid-stream

* fix(audio): keep transcription's positional arguments and redact streamed error details

- Move the new languages, keywords and stream options to the end of transcription's parameters, so a prompt or format passed by position keeps its meaning
- Redact internal hostnames, paths and tracebacks from a streamed transcription's mid-stream error event, as chat streams already do
- Move the CA-bundle check for the realtime HTTP routes, which serves real TLS on loopback, from the unit suite to the SDK integration suite

* fix(audio): stream the guarded transcript to SDK callers that asked for a stream

* fix(logging): keep a streamed transcript out of callbacks that turned off message logging

A streamed transcription's assembled response reached success callbacks with its text intact under turn_off_message_logging or a callback's message_logging=False, because the shared streaming redactor had no transcription branch. It now redacts the text, as the unstreamed call already does

* fix(proxy): stream a transcription the deployment streamed when the client sent no stream field

refactor(router): route the router family through RoutingContext and close the outside surface (#49118)
Strategies, pre-call checks, cooldown and fallback helpers, and the auto, complexity and quality
sub-routers now take a RoutingContext instead of the Router, and read the router only through
registry(), settings(), health() and the context's forwarding methods. Router-free helpers move
from router_utils to litellm_core_utils, outside callers of router state switch to entry points,
and the surface allowlist shrinks to the endpoint methods plus the entry points

* fix(http_handler): isolate ssl context for http2 clients

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(http): add an HTTP/2 opt-out and harden the Vertex AI Search HTTP/2 client

litellm.http2 is now unset by default, so http2: false or LITELLM_HTTP2=False
turns the provider's HTTP/2 default off. A caller's own SSLContext keeps the
search on HTTP/1.1, the HTTP/2 async client honors DISABLE_AIOHTTP_TRUST_ENV,
forced IPv4 transports get the CA bundle and client cert, and vector store
search retries once when the server drops the connection with a GOAWAY.

* fix(http): retry vector store search only on HTTP/2 GOAWAY and keep aiohttp pool and proxy behavior

Scope the one retry to a connection Google closes with an HTTP/2 GOAWAY and
log it. When HTTP/2 replaces the aiohttp transport, keep aiohttp's idle
keepalive and connection cap, and only then skip env proxies under
DISABLE_AIOHTTP_TRUST_ENV, so the global LITELLM_HTTP2 toggle keeps HTTPS_PROXY

* test(http): cover the vector store search GOAWAY retry in unit tests and drop duplicate SSL cache comments

* fix(http): open another HTTP/2 connection once 100 streams are in use

httpcore keeps every request to an origin on one HTTP/2 connection and caps it at 100 concurrent streams, so request 101 and later waited with no timeout. The handlers now spread requests over extra connections, opening one only when every open connection has 100 streams in flight. The force_ipv4 wire tests now cover ssl_verify=False and the client certificate.

* fix(vertex_ai): reuse one Vertex search OAuth token across searches

Every vector store search built a new search config, so the token cache it carries was thrown away and each search fetched a new Google OAuth token with a blocking call on the event loop. Under a burst of searches that blocking fetch held back every HTTP/2 response. The provider config is now shared, so searches with the same credentials reuse one token until it expires.

* fix(http): keep the HTTP/2 connection spread within the connection cap

* fix(http): keep sync vertex search on HTTP/1.1, since httpcore's sync HTTP/2 is not thread-safe

httpcore 1.0.9 hands two threads the same HTTP/2 stream id, so threaded sync
searches failed with protocol errors. Only the async client, which the proxy
uses, now defaults to HTTP/2, and the sync connection spread is removed.

* fix(http): split the connection cap across HTTP/2 lanes

Each lane had its own pool with the full connection cap, so an origin answering
HTTP/1.1, or several origins on one client, could exceed max_connections once
more than 100 requests were in flight. Lanes now open only while lanes times
100 streams stay under the cap, and each lane pool gets at most 100 of it.

* test(http2): scope wire-test peer logs to each fixture instance

* fix(http2): keep TE, force_ipv4 trust, evicted-client and opt-out behavior on the HTTP/2 path

- drop TE values other than trailers on https requests through the HTTP/2 spread, since h2 refuses them
- force_ipv4 transports keep httpx's default trust store (SSL_CERT_DIR) unless SSL is configured
- the evicted client closer asks the HTTP/2 spread whether a request is in flight
- LITELLM_HTTP2 set to 0, no or off, and a quoted "false" http2 setting, opt out of HTTP/2
- the wire test's held-search barrier waits on an event instead of polling

* fix(http2): count proxy-mounted transports when checking an evicted client for in-flight requests

* test(http2): move the HTTP/2 eviction cases that open a loopback server into the integration wire tests

* fix(http2): read an unquoted http2: 0 as off and free the stream slot of a response dropped without closing

* fix(http2): free the stream slot of a partly read response dropped without closing

* test(http2): check that the evicted client and its stream close after a partly read response is dropped

fix(logging): mark mirrored silent_model calls with is_silent_experiment in spend logs (#48888)
* fix(logging): mark mirrored silent_model calls with is_silent_experiment in spend logs and logging payloads

* fix(router): keep the mirror flag when litellm_metadata is set and strip a client-sent is_silent_experiment

Spend rows read router metadata from litellm_metadata when a call carries it, so the router now sets the flag there too. The proxy drops a client-sent is_silent_experiment with the other router-owned keys, so real traffic cannot be recorded as mirrored.

* fix(logging): mark mirrored calls with a router-only key so clients cannot set is_silent_experiment

Spend rows and the standard logging payload now derive is_silent_experiment from _litellm_silent_experiment, which only the router writes and the proxy and pass-through routes strip from client metadata. A caller's own is_silent_experiment key stays untouched, so it keeps its current effect on mirroring and on provider metadata, and unmirrored calls log false in both places.

* test(langfuse): expect is_silent_experiment false on every logged generation

* fix(logging): mark mirrored calls with a router-only enum value so no client route can set is_silent_experiment

The router stamps SilentExperimentMarker.MIRRORED, which client JSON can never produce, so batches, Responses WebSocket frames and pass-through need no strip. Langfuse layers the flag after its requester-metadata dedupe.

* fix(logging): set is_silent_experiment only on mirrored calls so real calls keep their payloads

Real calls no longer gain an is_silent_experiment key in spend rows or the standard logging payload, so OTEL, S3, GCS and every other logger receive what they did before. The Langfuse regression test now runs the real prompt helper.

* fix(logging): keep the mirror marker out of callback metadata and read the spend-row flag from the logging payload

Logging now strips the router's mirror marker from the request metadata buckets before any callback or vendor sees it, without touching the router's own dicts, so retries keep it. Spend rows read is_silent_experiment from the standard logging payload, which survives the collector's JSON round trip, so collector-mode rows keep the flag too.

* fix(logging): mark mirrored calls through a context variable so router usage counts them once

* fix(router): leave callback-started calls unmarked and stop client flags from turning mirroring off

Logging handlers now run outside the mirrored-call context, so an LLM call a success or failure callback starts while logging a mirrored call is not flagged as mirrored. The guard against mirroring a mirror reads the same context variable instead of request metadata, so a client-sent is_silent_experiment no longer skips the mirrors. The unused module-level get_standard_logging_metadata stops copying resolved keys from raw metadata.

* fix(router): keep main's client flag mirroring skip and the other logging metadata keys

A client's is_silent_experiment: true skips mirroring again as on main, the module-level get_standard_logging_metadata drops only the flag, and the silent experiment tests wait on a logged-call signal instead of polling a deadline

* fix(logging): take the mirror flag in Prometheus labels and Datadog cost tags only from the router

* test: type the new parametrized tests and keep the recorder from changing its argument

* fix(datadog): keep client request tags from setting the silent experiment cost tag

A request tag is_silent_experiment:true set the Datadog cost tag on a direct call.
Only the router flag sets it now. Also covers the sync failure handler's
mirrored-call reset with a failure function callback test.

fix(aiohttp_transport): close an owned aiohttp session when its transport is collected (#48650)
An OpenAI or Azure SDK client litellm built and evicted from the client
cache is usually garbage collected inside the closer's 900 second grace
window, so the closer's weak reference dies and the client's aiohttp
session is never closed. LiteLLMAiohttpTransport.__del__ now hands an
owned, still-open ClientSession to _close_recycled_session, which already
covers the current-loop, foreign-loop and closed-loop cases.

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(langfuse_otel): keep joined-trace tags, mask trace io, leave v2 trace io to the root

Joined traces (existing_trace_id) keep the caller tags they carried before,
and only the derived trace fields are skipped for them. mask_input and
mask_output now redact the derived trace input and output, matching the
vanilla Langfuse callback. The v2 mapper derives the trace name only,
because the root observation already carries the trace input and output
there. Uses the public preset cache key helper, moves imports to module
top, restores the original formatting of the unit test file, and adds
integration cells for the v2 llm_only scope and SDK sync/async calls.

* fix(langfuse_otel): split string caller tags the way Langfuse reads them

A caller tags value given as a comma list or a JSON array string (body
metadata.tags or the langfuse_tags header) used to reach Langfuse raw,
where ingestion split it into separate tags. Merging it with the derived
tags kept it as one tag, so parse it the same way before the merge

* test(otel): expect langfuse.trace.name on the v2 langfuse_otel generation span

* fix(langfuse_otel): read string mask flags the way the classic callback does

The langfuse_mask_input / langfuse_mask_output headers arrive as strings,
so "false" redacted the derived trace io. Parse them with str_to_bool and
fall back to truthiness, as the classic langfuse callback does

* fix(langfuse_otel): derive trace fields only on traces litellm starts

A litellm span that joins a trace an app or caller started (inbound
traceparent, the app's active span, a caller-provided parent span) no
longer gets a derived trace name, input, output or tags, like a request
joining an existing_trace_id. Langfuse applies the later-starting span's
trace update, so the derived values overwrote the app's own trace name
and io.

OTel v2 derives the name on the request root only when it has no parent,
and the generation span keeps main's caller-only trace name.

* test(langfuse_otel): keep main's OTel v2 generation key set in the arize family cell

The OTel v2 generation span no longer carries a derived langfuse.trace.name,
so the pinned key set goes back to main's.

* fix(langfuse_otel): name the OTel v2 request root once, from the request's own call

The v2 Langfuse logger re-derived langfuse.trace.name on the request root
for every LLM call in the request. A post_call llm_as_a_judge guardrail's
judge call replaced the caller's trace_name on the root with
litellm-acompletion, and with another v2 callback (otel, arize_phoenix)
listed before langfuse_otel that vendor's root span gained
langfuse.trace.name on every request.

The derived name now fills only an unnamed root this logger's provider
started, and never comes from a call litellm makes for its own features.
A caller trace_name still names the root on every call, as on main.

* fix(langfuse_otel): keep the derived trace fields from pushing other attributes off a full span

The derived trace name, tags, input and output were written after the OpenInference attributes with no room
check, so a span near the SDK's attribute limit (about 34 tools at the default 128) evicted keys main
exported, such as openinference.span.kind, metadata and llm.model_name, and raised the dropped count.
They are now written last and only into the room the limit leaves next to the error attributes a failed
call adds, so a full span exports what it would without them.

* test(langfuse_otel): give the full-span cells' derived request a caller trace id, as the joined one's traceparent does

* chore(langfuse_otel): drop the docstrings and comments the house rule disallows and type the new tests' parameters

* test(langfuse_otel): set the span attribute limit the full-span tests run at and keep Final locals out of the app-trace loop

fix(prometheus): count provider-side 401s in LLM failure and deployment metrics (#46668)
* fix(prometheus): count provider-side 401s in LLM failure and deployment metrics

The invalid virtual key skip no longer applies to an error the LLM provider
returned while the deployment was called with its own credential, so a 401
for a bad deployment credential increments litellm_llm_api_failed_requests_metric,
litellm_deployment_failure_responses and litellm_deployment_total_requests and
marks litellm_deployment_state as a partial outage again. Proxy-gate rejections
and a failing credential that belongs to the caller (a rejected per-user
credential, an api_key sent with the request, a per-user GitHub Copilot
session) keep the skip

* fix(prometheus): keep a caller's own Anthropic OAuth token failure out of the deployment metrics

A provider 401 on an Anthropic OAuth token the caller forwarded through the proxy is the caller's credential
failing, so it stays out of the deployment failure and outage series like a caller-supplied api_key. Adds
integration cells for an Anthropic deployment's own key, the forwarded caller OAuth token and a direct SDK
call that brings its own key

* test(prometheus): pin how a caller's own key or Authorization header on a deployment is counted

An SDK Router call that passes its own api_key is counted against the one-off deployment the router builds for that key, so the operator deployment keeps only its own failure. A provider 401 on an Authorization header the caller sends through the proxy counts against the deployment, as on v1.80.12

* fix(prometheus): keep caller-sent provider credentials and token-exchange 401s out of deployment metrics

A caller can send its own provider credential in the request body, such as
azure_ad_token, azure_scope, the Azure Entra app fields, watsonx token,
gigachat_access_token, OCI keys, AWS keys or Vertex credentials, at the top
level or inside extra_body. A provider 401 on that credential is the caller's
failure, so it stays out of the shared deployment's failure, request,
LLM-failed and state series, as on main. A token-exchange deployment trades the
caller's identity token on every call, so its 401s stay out as well, matching
the router cooldown.

* test(prometheus): Final locals, precise helper types and one for per comprehension in the new test helpers

* test(prometheus): pin that a provider 401 at a caller-sent api_base counts against its one-off deployment

* fix(prometheus): keep a provider 401 on caller-sent headers out of deployment metrics

A caller can override the deployment's credential with headers it sends in the
request body: headers or provider_specific_header, or an Authorization, api-key,
x-api-key, x-goog-api-key or Ocp-Apim-Subscription-Key entry in extra_headers.
A provider 401 on such a request is the caller's failure, so it stays out of the
shared deployment's failure, request, LLM-failed and state series, as on main.

* fix(prometheus): skip a provider 401 only when the caller's headers carry a credential

The proxy now records headers, extra_headers or provider_specific_header in
credential_fields only when they name a provider credential header
(Authorization, api-key, x-api-key, x-goog-api-key, Ocp-Apim-Subscription-Key),
the same way api_key is recorded. A caller that sends a plain header such as a
trace id still has a provider 401 on the deployment's own key counted against
the deployment.

* fix(prometheus): stamp credential_fields after the proxy forwards the caller's headers

A provider credential header the proxy forwards from the caller's HTTP request
(forward_llm_provider_auth_headers + forward_client_headers_to_llm_api) lands in
data["headers"] after proxy_server_request is built, so the stamp missed it and a
401 on that caller credential was counted against the deployment. Compute the
stamp after the header forwarding steps and pin both forwarded cases.

* fix(prometheus): skip a provider 401 when the caller sends any header or an OpenAI organization

The proxy now records headers, extra_headers or provider_specific_header in
credential_fields whenever the caller sends or the proxy forwards any header
there, and records organization when the caller sends one in the body or as a
forwarded OpenAI-Organization header. A forwarded header can be a gateway key
such as x-portkey-api-key or an OpenAI-Project id, and a wrong organization
gets a 401 from OpenAI, so these 401s stay out of the deployment metrics as on
main instead of marking a healthy deployment as a partial outage.

* fix(prometheus): ignore the user information the proxy adds when stamping caller headers

With add_user_information_to_llm_headers on and header forwarding enabled, the
proxy adds x-litellm-user_api_key_* headers to the forwarded headers. Those
carry the proxy's own key and user details, not the caller's, so they no longer
make a request look caller-scoped, and a provider 401 on the deployment's own
key on such a request is counted.

* fix(prometheus): skip a 401 raised before the provider is called or at the caller's own endpoint

A deployment with no key of its own fails with LiteLLM's local "Missing
Anthropic API Key" 401 before any provider call, and a caller who sends
aws_bedrock_runtime_endpoint (or another provider endpoint field) can get a
401 from their own gateway. Both were counted against the shared deployment
and marked it as a partial outage, where main skipped every 401.

Count a 401 only once the provider was called (api_call_start_time is set),
and treat caller-sent provider endpoint fields like caller credential fields.

* fix(prometheus): count the deployment's own 401 on requests that carry only anthropic-version or anthropic-beta

The Anthropic SDK sends anthropic-version on every request, and the proxy copies
anthropic-version and anthropic-beta into provider_specific_header for Anthropic,
Bedrock and Vertex. Both were treated as caller headers, so a 401 on an Anthropic
deployment's own key from any Anthropic SDK client stayed out of the deployment
metrics.

These two headers only pick the API version and beta features. Anthropic answers
a bad anthropic-version or an unknown anthropic-beta with a 400, never a 401, so
they cannot turn the deployment's own key into a 401 and no longer mark the
request as carrying a caller header.

* test(prometheus): read and write the owned proxy's own database in the expired-key and MCP cells

Since #47213 an owned proxy boots on a private database, so the expired-key update and the MCP guardrail row read now go through the gateway's database_url instead of the worker's.

* fix(prometheus): keep credential_fields as main stamps it and give Prometheus its own caller_credential_fields

credential_fields tells the Rust OCR bridge which stripped body fields the
caller sent. Repurposing it for the Prometheus caller-credential check changed
its value (organization and extra_headers added, anthropic-version-only
headers dropped). Restore main's stamp unchanged and stamp the Prometheus
classification under caller_credential_fields, which only Prometheus reads.

* fix(prometheus): skip a provider 401 on a stored credential the caller picks by litellm_credential_name

A request body litellm_credential_name swaps the deployment's stored
credential for one the caller chose, so a 401 on it is the caller's, not the
deployment's. Treat it like the other caller credential fields so it no longer
marks a healthy shared deployment as a partial outage.

fix(router): stop concurrent deployment deletes from crashing deployment lookups (#47680)
* fix(router): stop concurrent deployment deletes from crashing deployment lookups

delete_deployment and upsert_deployment shrink model_list before they repair
the index maps, so a lookup on another thread in that window read a stale
index: IndexError, or the neighbouring deployment and its credentials. An add
racing a delete could corrupt the index for good.

One RLock now covers model_list and the three index maps. Delete, upsert, add
and the set_model_list reset change them under it, and every lookup that turns
an index into a deployment reads under it.

Fixes #45242

* test(router): release the held delete when the read reaches the index lock

The race tests released the held write after a fixed 0.2 s, so a reader the runner
stalled past it read the repaired list and passed on unfixed code. The read now runs
on its own thread and the write stays held until the read returns or reaches the
router's index lock; the 10 s bound only fails a broken synchronization.

The integration test gains the audit cells: chat, streaming, Responses and
Anthropic messages calls (sync and async, by model name and team public name)
during a held delete, the same for upsert, add and set_model_list, a request for
the deployment being deleted, a provider error, a double delete, and thread and
async bursts during upsert churn.

* test(router): cover the early return of a delete and the team filter of get_model_ids

delete_deployment now returns None from inside the index lock, and get_model_ids by
name reads its deployments through _deployments_named; pin both: deleting an unknown
id returns None and leaves the list alone, and exclude_team_models drops only the
team deployment.

* fix(router): read deployments by name under the index lock outside the Router

The response polling provider check, the complexity router's adaptive pool and the
savings baseline turned the name index into list positions themselves, so a concurrent
delete could still hand them a stale slot. They now read through Router.deployments_named,
which takes the deployment index lock.

* fix(router): type the locked deployment lookups as DeploymentTypedDict

deployments_named and _team_deployments_named returned tuple[Any, ...]. They now return
DeploymentTypedDict rows, which is what model_list holds. The adaptive pool setup in the
Router and the complexity router drop their branches for pydantic Deployment rows, which
these lookups never return, and should_include_deployment accepts the typed row.

test(streaming): pin that a stream stuck on one chunk closes its provider stream and logs one failure (#38753)
* fix(streaming): stop re-raising and re-logging a failed stream on every next()

A stream that raised keeps its provider iterator alive, so a consumer that iterates past the error re-detected, re-raised and re-logged the same failure on every call, flooding failure callbacks for one request. Latch the failure and re-raise it without logging again.

* fix(streaming): drop the retained traceback before re-raising a failed stream

* test(streaming): count failures through a real logging callback and require a clean stop on later reads

* test(streaming): require the stuck stream to close early and release its socket

The provider stream now records a GeneratorExit and caps its chunks, so draining it or detecting the loop late fails. Two wire cases check a sync and an async stuck stream release their TCP session.

* test(streaming): avoid failure recorder name collision

fix(harness): set PWD to the working directory of local sandbox commands (#47530)
* fix(harness): set PWD to the working directory of local sandbox commands

LocalSandbox started CLIs in the sandbox workdir but passed the parent's PWD through. OpenCode reads PWD as its project directory, so a litellm.agent() turn worked in the Python process cwd instead of the sandbox.

* fix(harness): re-home resumed OpenCode sessions into the sandbox folder

OpenCode files each session under the folder it ran in and only streams a resumed session's events from that folder, so a session saved before PWD pointed at the sandbox, or resumed in another sandbox, hung. Resume now runs opencode export and import in the sandbox first. Also types the CLI handler's config so its member accesses are known.

* fix(harness): fail an OpenCode resume that cannot move its session, with a timeout

The export and import step now has a 30 s bound, and a failure or timeout raises HarnessError instead of leaving the resumed turn waiting forever. A restart of a session the handler already ran skips the step.

* fix(harness): resume an OpenCode session elsewhere as a copy and fail the turn when it cannot

Importing the exported session moved it, so the original stopped working
where it was saved. Resume now imports a copy under fresh ids, filed under
the sandbox folder, and continues the copy. A failed or timed-out export or
import ends the next turn with runtime_error, as base does for a missing
session, instead of raising from agent_resume.

* fix(harness): retry a failed OpenCode resume on the next turn and keep resumed copies stable

Resume now only records the saved id, and the first turn runs the OpenCode export and import under the caller's timeout. A failed export fails that turn and the next turn tries again. The local sandbox kills a command when its run is cancelled, and the copy names the sandbox folder so OpenCode 1.15.5 and older keep it there.

* test(harness): keep subprocess tests out of tests/unit

The PWD regression test moves to tests/integration/sdk with an isolated child interpreter, and the cancel test checks collect_output with an in-process process instead of a real one. collect_output takes the sandbox Process protocol.

Responses and chat tool use (function tools, function_call items, tool messages) is now converted the way Claude chat inference converts it before the Anthropic, Azure AI and Vertex partner counters call count_tokens. Translation errors answer 400 before any provider call. Anthropic-shaped requests and /v1/messages/count_tokens keep their body as sent.

* test(count-tokens): compare Claude count bodies with inference for Responses tool use

* fix(responses): forward the caller's Responses body to OpenAI token counts

OpenAI deployments now get the caller's /v1/responses/input_tokens body as sent, minus LiteLLM-only fields, so OpenAI's own count and errors come back. previous_response_id is checked for ownership like inference and routes to the deployment that served it

* fix(responses)!: count Claude Responses bodies the way inference sends them

Non-native Responses counts now run the body through the inference bridge, so
text.format, tool_choice, reasoning, built-in tools, and file_search count the
way inference sends them on Anthropic, Azure AI, Vertex, and Bedrock. The
OpenAI native count body uses the drop_params-resolved tool fields.

* fix(responses): honor drop_params and replay previous turns in Claude counts

Claude input_tokens counts now read the same drop_params setting inference merges from the deployment, router defaults, and request, so a forced tool_choice downgrades to auto under drop_params. previous_response_id replays the stored turns through inference's session loader, and chat messages carrying fields beyond role and content go through the provider's chat translation

* fix(responses): keep proxy-only request keys out of OpenAI counts and map chat tools in Bedrock counts

* fix(count-tokens): import on Python 3.11 and keep stored prompts in OpenAI counts under drop_params

* fix(responses): leave tool_choice out of counts when drop_params drops every tool

* fix(count-tokens): count Mantle options, drop cache marks, and reject input inference cannot send

The Bedrock Mantle fallback now counts thinking, tool_choice and output_config
like the runtime count. Claude Responses counts leave out cache_control marks
again, so more than four marks count instead of failing. Counts answer 400
before any provider call for user blocks chat inference refuses and for
Responses tools with no Chat Completions equivalent, instead of dropping the
block or counting a placeholder tool. Adds the wire tests for these paths

* fix(count-tokens): count Responses tools the way the inference bridge sends them

A Claude count now hoists additional_tools input items into tools, strips a malformed tool flag under drop_params and rejects it without, and leaves tools out when the deployment lists tools in additional_drop_params, so the count matches the body Claude inference sends for the same request

* fix(count-tokens): keep Bedrock runtime counts option-free and send OpenAI the provider file id

* test(count-tokens): capture the Anthropic count request at the HTTP layer instead of patching the handler

* fix(count-tokens): ignore a caller-sent file id mapping and keep non-string file ids as sent

fix(streaming): keep finish_reason and provider usage when rebuilding streamed text completions (#44349)
* fix(streaming): keep finish_reason and provider usage when rebuilding streamed text completions

stream_chunk_builder_text_completion read finish_reason from chunks[-1] and recounted usage from messages. With include_usage the last chunk is a usage-only trailer, so finish_reason came back None (or raised IndexError when the trailer had no choices), and prompt_tokens was 0 because a text-completion prompt is not in messages. Scan for the last finish_reason and prefer the provider-reported usage, as the chat path already does.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(streaming): type the text completion chunk builder so its scans add no basedpyright debt

Read chunk fields as typed attributes instead of untyped subscripts, which
clears the reportUnknownArgumentType breach the lint gate flagged

* fix(streaming): keep the provider's full usage, including token details, when rebuilding text completions

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(streaming): rebuild dict-form text completion chunks again

stream_chunk_builder routes dict chunks holding TextChoices to the text
completion builder, which now reads attributes. Convert them to
TextCompletionResponse at the routing point.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(streaming): accept dict chunks in the text rebuild and derive its usage like the chat path

Moves the dict to TextCompletionResponse conversion into stream_chunk_builder_text_completion so direct callers keep working, and builds usage through ChunkProcessor.calculate_usage over the chunks that report counts, so a trailer without total_tokens keeps its prompt and completion counts and the result is a fresh Usage

* fix(streaming): read text completion usage through the shared usage extractor so usage dicts on typed chunks rebuild

* fix(streaming): merge text completion logprobs across chunks and rebuild dict text chunks as text completions

* fix(streaming): rebuild one text completion choice per index and keep null logprobs fields null

* fix(streaming): keep dumped chat chunks with a choice-level text on the chat rebuild path

Route a dict chunk to the text completion builder only when its choice has `text` and no `delta`.
The Responses bridge snapshots chat chunks with model_dump(), and Together's chat choices carry `text`
next to `delta`, so streamed /v1/responses calls to Together ended without response.completed.

Group text completion choices by index in one sorted pass, so rebuilding an n>1 stream costs about
the same as rebuilding an n=1 stream of the same size.

* fix(streaming): keep text completion rebuilds working on mixed chunks and unreadable logprobs

A chat chunk inside a text completion stream now converts to a text chunk that keeps its finish_reason and adds no text. A dict chunk whose logprobs fail validation is read again with logprobs dropped, and logprobs that are not a Logprobs object keep the last value sent. Each of these inputs raised or lost data at the previous commit, and each now rebuilds without raising

Also adds a Purview test showing a multi-choice text stream is blocked like the non-streamed response, and Final annotations on the new test locals

* fix(streaming): rebuild text completion choices without an index at index 0

Text completion choices whose index is None now rebuild under index 0, as on the merge base, where the sort by index raised at the previous commit. A chat chunk inside a text completion stream now keeps the usage it reports, and a choice whose logprobs mix a Logprobs object with another shape keeps the last value sent, as on the merge base

* fix(streaming): rebuild text completion choices with a string index under that int

A text completion choice whose index is a string now rebuilds under the int it names, and one whose index cannot be read as an int rebuilds at index 0, as on the merge base. A string index mixed with an int index raised TypeError at the previous commit, and a string-only index came back as a string

* test(streaming): drop a docstring that repeats its test

* fix(streaming): fall back to choice 0 for an infinite text completion index

A float infinity index made int() raise OverflowError, which the index
coercion did not catch, so the rebuild failed where the merge base
returned choice 0.

fix(speech)!: correctly propagate spend logging and usage for Gemini TTS bridge (#44551)
* fix(speech): correctly propagate spend logging and usage for Gemini TTS bridge

* fix(speech): call Gemini once per TTS request and log the bridge's token usage

aspeech re-ran speech whenever the first result was not a coroutine, so the
speech-to-completion bridge sent every Gemini TTS request upstream twice. It
now returns the sync result.

The bridge's inner completion runs as an internal sub call, so only the
speech call fires success callbacks, and the completion's usage rides on the
audio response so the spend log and usage_object carry real token counts.

Replaces the separate inner Logging object and the cost_calculator fallback,
which never reached the spend row.

* fix(speech): flag a cached Gemini TTS reply as a cache hit so it logs at no charge

* fix(speech): price a cached Gemini TTS reply's savings from its token usage and keep its cache key

* test(integration): cover Gemini TTS speech billing, logging, cache hits and deployment TPM

* test(integration): start the speech TPM cell in a minute's first 10 s so the two requests never cross a minute

fix(bedrock): send native structured output first on Opus 4.8 and Sonnet 5 and fall back to the json tool when Bedrock rejects it (#47100)
* fix(bedrock): send native structured output first on Opus 4.8 and Sonnet 5 and fall back to the json tool when Bedrock rejects it

* fix(bedrock): retry with the json tool when Bedrock refuses the native output schema

Count a 400 under output_config.format.schema: as a native output rejection, so a schema Bedrock cannot compile (like a pattern with a nested {n,m} group) gets the json tool retry instead of reaching the caller

* fix(bedrock): make the native output retry send what an opted-out deployment sends

The retry after a native output rejection now reruns the same optional param
mapping completion() ran, with the deployment model_info opted out of
supports_bedrock_native_structured_output, so tool_choice, effort and the json
tool schema match an opted-out deployment instead of a hand-built tool. Each
config keeps only the predicate that decides when native output came from the
opt-in key.

Bedrock batch records for Anthropic models map with the opt-in turned off,
since a batch job has no retry. Models on supports_native_structured_output
keep native output in batch

* fix(bedrock): build the messages retry from the caller's request and keep other errors unchanged

* fix(bedrock): give sync converse stream errors the upstream body as text

* fix(bedrock): let a malformed caller outputConfig reach Bedrock instead of raising

A Converse json_schema request whose caller outputConfig failed litellm's
shape check raised a pydantic error before the request was sent, so the
caller got a 500 where the merge base passed Bedrock's 400 through. The
opt-in check now treats that outputConfig as carrying no native output.

Also opts the vertex wire test's pinned Opus 4.8 json tool deployment out of
native output, and extends the Bedrock native output integration tests.

* fix(bedrock): send a refused caller outputConfig once and give opt-out advice only when native output is unsupported

A caller can send its own outputConfig on Converse. When Bedrock refused that
schema on an opt-in deployment, the retry still carried the caller's textFormat,
so Bedrock got the same request twice and the warning told the operator to turn
off an opt-in that was not the cause. The retry is now skipped when the opted-out
request would still carry a native textFormat, so Bedrock's 400 reaches the
caller after one call as on the merge base. The opt-out advice is logged only for
the account-level "Extra inputs are not permitted" rejection.

* fix(bedrock): keep the caller's continuation message on the native output retry

The Converse transform pops user_continue_message from litellm_params on the first attempt, so a retry built from those params afterwards dropped it. Both Bedrock chat routes now hand the fallback a copy taken before the first attempt.

* test(bedrock): pin additional_drop_params on the /v1/messages native output retry

* fix(bedrock): give the Converse native output retry the fake stream timeout

fix(streaming): report the deployment's api_base when a stream fails mid-way (#47045)
* fix(streaming): report the deployment's api_base when a stream fails mid-way

* fix(responses): report the deployment's api_base when a native responses stream fails mid-way

* fix(streaming): name the deployment's configured api_base in mid-stream errors and keep prompt text out

Mid-stream errors on chat and native /v1/responses streams now prefer the router's configured api_base over the logged request URL, websocket turns keep the connection's api_base, and the mid-stream mapping no longer adds the prompt to the debug info.

* fix(streaming): keep api_base credentials out of error debug info and leave websocket turn logging unchanged

* fix(streaming): name the websocket connection's api_base on turn failures and strip scheme-less userinfo

* fix(streaming): strip api_base userinfo before cutting the query so a raw ? or # in a password stays out

Adds the audit's integration tests for the mid-stream alert API Base line and the SDK debug info.

* fix(streaming): leave the API Base line out when an @ follows the host

A raw / ? or # in a password and an @ in a query or path read the same in a malformed api_base, so either guess could show a secret or a wrong host.

* fix(streaming): keep the API Base line when an @ sits in a provider path

Vertex partner model ids like claude-opus-5-5@default put an @ in the URL path, so the fail-closed rule left out the line main printed. The line is now left out only when the text before the first / ? or # is not a host, and a :// counts as the scheme only after a valid scheme name.

* test(streaming): cover a numeric password with a slash in the API Base line

The audit found that a password like 1234/function-secret, which looks like a port, had no case. The line is left out on this branch and printed the raw secret on main

fix(bedrock): use native structured output on Haiku 5.5 and Sonnet 5.5, and fix Fable 5 and Sonnet 4.6 schema 400s (#46870)
* fix(bedrock): use native structured output on every Claude model whose Bedrock profiles accept it

Bedrock accepts outputConfig structured output on every reachable profile of
Claude Opus 4.7, 4.8, 5, 5.5, Sonnet 5, 5.5, Haiku 5.5, and Fable 5.1, so
json_schema now goes out natively there instead of as a forced tool, which kept
Bedrock from returning adaptive thinking. Fable 5 rejects outputConfig, so its
keys go back to the tool path. GovCloud keys keep their flags, and the drift
tests let GovCloud lag its commercial base but never lead it.

* fix(bedrock): clean Claude schemas for native structured output and keep recursive schemas on the old path

Bedrock native output rejects minimum/maximum, minItems, uniqueItems, oneOf,
additionalProperties true, and recursive or unresolved $ref, all of which the
forced tool accepted. Claude schemas on the Bedrock native paths now go through
the cleaner the Anthropic native path already uses, and a schema with a
recursive or unresolved $ref keeps the forced tool, inline, or drop path it had.

* fix(bedrock): keep older installs on the json tool with a Bedrock-only native output key

Older installs fetch the model map from main, so flipping supports_native_structured_output
moved them onto native output with their old schema handling. The new
supports_bedrock_native_structured_output key is ignored by older code. Schemas native output
cannot hold (recursive refs, open objects such as dict fields) keep the json tool on the new
key, models on the old key keep their current behavior for those shapes, and the Anthropic
API, Vertex AI, and Azure keep their current behavior.

* chore(cost-map): regenerate the model prices schema for the Bedrock native output key

* fix(bedrock): keep native output to profiles every account accepts and route schemas Bedrock rejects to the json tool

Only Opus 5.5, Sonnet 5.5, Haiku 5.5 and Fable 5.1 keep the Bedrock native output key, since
Opus 4.8 and Sonnet 5 answer 400 on some accounts and Opus 5 garbles escaped characters.
Lookaround patterns and string formats outside Bedrock's list now keep the json tool, objects
typed as a union with null are closed, and the cleaner keeps minItems of 0 or 1.

* fix(bedrock): keep Opus 5.5 and Fable 5.1 on the json tool, since native output stops their adaptive thinking

* fix(bedrock): keep shared $defs in native schemas and send refused schemas to the json tool on every native model

Native output now keeps $defs instead of inlining each use, so a submodel reused across a schema counts once against Bedrock's optional and union limits. Schemas native output cannot hold use the json tool on Converse and Invoke chat for both native keys, and minItems is only kept when it is an integer 0 or 1

* fix(bedrock): keep the json tool unless thinking is requested and bound native output schemas

The Bedrock native output key now applies only when the call asks for thinking, so calls without
thinking keep the json tool as before. Schemas past Bedrock's documented union and optional counts,
or past a grammar size estimate fitted to live probes, keep the json tool on both map keys. Open
objects keep the json tool on the Anthropic API, Vertex AI and Azure AI, where native output returned
them empty. The $ref check no longer expands $defs, so doubling definitions no longer stall the request.

* fix(bedrock): resolve root-path $defs refs so nested Pydantic models keep native output on Invoke

* test(bedrock): cover native structured output and json tool routing through the proxy

Integration cells drive the proxy against a scripted Bedrock peer that enforces Bedrock's structured output schema rules, covering thinking with native output on Converse, Converse streaming, Invoke, /v1/responses and /v1/messages, the deployment opt-in, Fable 5, schema cleaning on every native entry, open objects, and malformed schemas. Vertex, Anthropic and Azure AI cells cover open objects on native-capable models and the cleaner's minItems and nullable object handling. The unit table now covers reasoning_effort none and disabled thinking

* fix(bedrock): keep native output for numeric formats and wide old-key schemas, and keep thinking in json mode

Check string formats only on nodes that can be strings, apply the 64-field cap only to the Bedrock-only key, carry thinking blocks into the json mode message, and send malformed json tool schemas as object schemas.

* fix(anthropic): keep native output for dict fields unless the json tool can be forced

* fix(anthropic): keep native output for dict fields when the caller sends tools

* test(bedrock): close the dangerous-tool-use test schema, since Bedrock native output requires closed objects

* test(anthropic): cover forced and unforced open-object routing, json mode thinking, numeric formats and wide schemas

Add proxy cells for open-object schemas that keep native output when the json tool cannot be forced (a model that refuses forced tools on the Anthropic API and Vertex AI, thinking, caller tools), for the thinking block a json mode answer keeps on Vertex AI and Bedrock Invoke, and for integer and number formats and 65-field schemas on each Bedrock map key. Point the forced open-object cells at the Anthropic API and Azure AI only, since no Vertex AI model in the cost map takes both native output and a forced tool

* fix(bedrock): keep the native output opt-in on the deployment that sets it, and route effort none open objects to native output

* test(bedrock): cover deployment-scoped native output opt-in, register_model and effort none open objects

fix(bedrock)!: keep reasoning, thinking blocks and the json_mode finish_reason on fake streams (#46863)
* fix(bedrock): keep reasoning, thinking blocks and the json_mode finish_reason on fake streams

A Bedrock Converse model without native structured output fakes the stream
when response_format carries a json_schema. The fake stream transformed the
response without json_mode and rebuilt a chunk from text, tool_use and token
counts only, so it dropped reasoning_content, the signed thinking_blocks and
the reasoning token count, and ended on finish_reason tool_calls.

The three fake-stream sites now pass json_mode to _transform_response and
stream the resulting ModelResponse through the shared
convert_model_response_to_streaming converter, which now numbers each
streamed thinking block with its index the way real streams do

* fix(bedrock): parse text tool calls on Converse fake streams like the non-stream answer

* fix(responses): stream the answer text when one chat chunk carries reasoning and the answer

* fix(streaming): keep every field on the OpenAI and openai_like fake streams and split multi-block thinking

Azure o-series and openai_like fake streams now use the shared MockResponseIterator, so extra tool calls,
reasoning and cached and reasoning tokens survive; the Bedrock-local iterator is deleted.

The /v1/responses bridge also splits a chunk whose thinking block is signed or redacted with no reasoning
text, and the sync iterator closes the reasoning item before the answer opens, like the async one.

The /v1/messages bridge gives each thinking block in a chunk its own content block, starts a new block when
the thinking block index changes, and streams redacted thinking as redacted_thinking.

Snowflake replays drop the stream index from thinking blocks.

* fix(anthropic): stream each thinking block's text once on /v1/messages

An unsigned thinking chunk now opens its content block with empty text, since its thinking_delta carries the text. A multi-block chunk keeps each piece's thinking block, so an unsigned block followed by a signed one keeps its own text and index.

* docs(anthropic): describe which thinking block start carries its text

* fix(streaming): close merged reasoning before the answer when one chunk carries both

* test(streaming): cover fake-stream reasoning across the proxy bridges and type the Snowflake replay test

test(integration): hand every harness server a port from one per-worker block (#46761)
* test(integration): hand every harness server a port from one per-worker block

About 45 places in the integration harness picked a port by binding port 0,
reading the number back, closing the socket and starting a server on that
number later. Another process could take the port in between, which surfaced
as "Address already in use" flakes. Earlier fixes retried around the race in
single call sites without removing it.

tests/integration/_support/ports.py now owns every port the harness picks
ahead of a server. Each pytest process claims a 200-port block between 10000
and 32767 by taking an exclusive flock on a per-block lock file in the system
temp directory, so parallel runs on one machine never share a block and the
lock goes away with the process. The range is above the fixed service ports
and below the Linux and macOS ephemeral ranges. Ports go out in order, are
never reused in a run, skip anything an outside process already holds, and
a process that exhausts its block claims the next free one.

The three _free_port copies, worker_endpoints' port-0 binds,
free_loopback_port, the owned proxy's lost-port-race retry and the owned
Redis retry loop are gone. Tests that restart a server on the same port now
allocate that port up front instead of reading it back from the first
server. TQ012 in scripts/check_test_quality.py rejects a port-0 bind read
back with getsockname anywhere under tests/integration.

feat(gemini)!: auto-continue gemini-4-argon long decodes with continuationToken (#46240)
* feat(gemini): continue MAX_TOKENS decodes with continuationToken across chat, streaming, and interactions

* fix(gemini): continue long decode on CONTINUATION and cancel interactions at /cancel

* feat(gemini): add public gemini-4-argon cost-map rows for AI Studio and Vertex AI

Add gemini/gemini-4-argon and vertex_ai/gemini-4-argon alongside the existing
early-access row, carrying the same limits and capabilities. The AI Studio row
mirrors the early-access entry; the Vertex row differs only in provider and
pricing source. Prices follow once Google publishes them.

Extend the mapped metadata test to cover all three ids, that each routes to its
provider, that its backup copy matches, and that the public rows carry the same
limits as the early-access row.

* feat(gemini): raise gemini-4-argon to the 1M long decode cap and report initial_prompt_tokens across hops

* chore(prices): build on the merged gemini-4-argon rows and only raise the long decode cap

* fix(gemini): follow continuation hops in a loop instead of recursion

The unary hop collectors and the stream iterator called themselves once per continuation request, which the recursion check in CI rejects and which would hit the interpreter's call depth on a very long output. They now loop, and a test follows more hops than the interpreter allows nested calls

* fix(gemini): bill Google Search grounding from every continuation request

Google sends search grounding once, on the request that ran the search, and does not repeat it on a continuation request. The merged response kept only the last request's grounding, so usage.web_search_requests and the per-search fee dropped every earlier search. Unary merges and the stream iterator now carry the grounding of every request in the chain

* fix(gemini): continue long gemini-4-argon answers on streams and Vertex AI

A continued stream stopped after the first chunk of its second request. The stream wrapper asks the iterator for a fresh start before every chunk, and that reset it to the first request's finished stream. The iterator now reads from the newest request's stream

On Vertex AI the continuation request went to the v1 API version, which rejects continuationToken with a 400. A request that carries the token now goes to v1beta1, which accepts it, including a token that v1 issued

On a stream, initial_prompt_tokens came from a usage chunk in the middle of the stream, which reports a smaller prompt count than the last chunk. It is now the count the first request's stream ends with, the same number a unary call reports

continuation_token is no longer forwarded on the Interactions API, which answers 400 for the field. It is dropped there as it was before this branch

* chore(gemini): name the type errors the dual-mode stream iterator trips

The stream iterator holds a sync or an async line iterator in one untyped attribute. Pointing it at a continuation request's stream gave the type checker a concrete union for it, so six existing lines that only ever run in one of the two modes started to report errors

This adds a rule-named suppression with a reason on each of those lines and changes no code. Splitting the class into a sync and an async iterator would remove them and is left for a follow-up

* fix(gemini): continue only when Google ends a request with CONTINUATION, and stop streaming mid-answer tokens

A long decode now sends the next request only when Google's finish reason is CONTINUATION, so an answer cut at the caller's own max_tokens returns in one request with its continuation_token instead of drawing a rejected extra request

A request for more than one choice is never continued, since Google rejects a continuation with more than one candidate

Chat-format streams no longer carry the tokens Google sends mid-answer. Only a stream that ends cut off carries a continuation_token, on its last content chunk

The response cache key now includes continuation_token, so a resend with a token is not served the earlier segment

* fix(gemini): keep one response id across a continued answer

A continued chat stream changed its chunk id each time the next request to Google started, and a unary answer came back under the last request's id. Every chunk and the unary answer now carry the first request's id, including the chunk that ends a cut-off stream

A request whose n or max_tokens arrives as a string is sent once and never continued, where it used to fail with a 500 on the comparison. An empty continuation_token no longer changes the cache key

* test(gemini): add integration cells for long decode continuation

Covers continued answers on chat, /v1/messages and /v1/responses, streamed and not, on the Gemini API and Vertex AI against a scripted Google, plus concurrency, outage and worker restart runs

Also moves the Google stand-in cancel route to /cancel, the URL this PR now calls for Interactions cancel, and checks the cancel test posts there exactly once

* fix(vertex_ai): fetch the access token again before each continuation request

A long Gemini 4 answer on Vertex AI can run for over half an hour of follow-up requests, and every one of them reused the bearer token fetched before the first request. Once that token expired Google answered 401 and the caller got a cut-off answer with finish_reason length

Each Google request in a chain now asks for the token again, which is a cache hit until the token nears expiry, on the streamed and unary paths, sync and async. A refresh that fails counts as a failed follow-up, so the caller still gets the answer so far with its continuation token. A caller's own Authorization in extra_headers still wins on every request, and the Gemini API key path is unchanged

* fix(vertex_ai): start each continuation stream with an empty parser buffer

When a Google stream ended on an unfinished frame, its leftover text stayed in the stream parser and every frame of the next continuation stream was appended to it. None of them could be decoded, so the whole continuation was billed and dropped without an error

Each continuation stream now starts with a fresh buffer, and a test covers a stream that ends on an unfinished frame, sync and async

* fix(vertex_ai): treat a continuation stream with no readable frame as a failed follow-up

A continuation stream that answered 200 and then sent Google's error frame first, sent a body that is not JSON, or dropped before its first frame ended the caller's stream with `stop` or an error and no token, so a cut answer looked complete or was lost. It now ends the way a refused follow-up does, with the answer so far, `finish_reason` length and that request's token

Every continuation stream request now also gets the caller's per-request timeout, which #46349 added to the first one, so a follow-up that never answers ends at that timeout the same way

* fix(vertex_ai): keep every follow-up's citations and URL context in a continued answer

A non-streamed answer that took several Google requests kept citationMetadata and urlContextMetadata from the last request only, and left every later request's offsets counting from that request's own text. So a URL read on the first request was missing from the answer, citations from earlier requests were dropped, and a later request's citations and search supports pointed at the wrong part of the joined answer

The joined answer now keeps every request's citations (Vertex AI's `citations` and AI Studio's `citationSources`) and URL context, and shifts each later request's citation and search support offsets by the UTF-8 bytes of the answer text sent before it, thought parts excluded, since Google counts these offsets in bytes

* fix(vertex_ai): answer when a candidate sends null citationMetadata or urlContextMetadata

A Gemini candidate whose citationMetadata or urlContextMetadata was JSON null made the call fail on every Gemini model, non-streamed with a 422 or 500 and streamed with an error event, because the per-request metadata helper handed the null back as is and the caller tried to extend a list with it. A continued answer also failed when a follow-up's citation or search support came with a null startIndex

A null field is now kept as one entry on a single request, as it was before this branch, a follow-up's null URL context adds nothing to a continued answer, and a null startIndex counts from the start of that request's text. Tests cover missing, null and empty fields on one request and on a continued answer, streamed and not

* fix(vertex_ai): pass through spans with no end index and point a continued stream's citations into the whole answer

A later request's citation or search support with no endIndex made the whole non-streamed answer fail with a 500, so a span Google sends without an end index now comes back as Google sent it, the way one request for the whole answer returns it. A span with an end index but no start index still counts from 0

A continued stream handed callers each later request's citation and search support offsets counted from that request's own text. The stream now adds the answer bytes of every earlier request, so the offsets point into the whole answer like the non-streamed path and one request for the whole answer

Adds the audit's wire tests for both, which fail 24 cells before this change

* test(vertex_ai): cover a later request whose cited span starts at its first byte with no start index

Google leaves out a zero startIndex, so the second request of a continued answer can cite its own opening with only an endIndex. These wire cells check that span lands where one request for the whole answer puts it, on Gemini and Vertex AI, chat and Responses, unary and streamed

* fix(vertex_ai): log a continued answer's raw response as one object

A non-streamed answer joined from several Google requests logged its raw response as a JSON list of every request's body. The OpenTelemetry logger reads that raw response as one Gemini body to set its `llm.gemini.*` attributes, so on a continued answer it hit a validation error and set none of them

It now logs the merged body, which carries only the last request's token, and a single request still logs Google's body unchanged. The new unit test fails with the change reverted

Also adds integration cells for a cut chat stream's token chunk, an answer joined from 41 requests, a caller that gave up on a non-streamed call, counts and caps that are not numbers or are sent twice, `n` sent as true, a partial answer cached after a refused continuation, the token in another provider's cache key, and the sync SDK path with its Vertex token refetch

* test(integration): check a continued answer logs one merged raw response

A non-streamed Gemini answer that took several Google requests now hands logging one merged response, so the OpenTelemetry span carries the llm.gemini attributes. These 12 cells fail on the merge base and on the commit before that fix, and pass on the branch

* test(vertex_ai): cover a follow-up tool call and its thought signature in long decode

* test(gemini): pin that a one-request answer logs Google's body unchanged

fix(anthropic): count a replayed server tool call's cache mark the way modify_params sends it (#46591)
* fix(anthropic): count a replayed server tool call's cache mark the way modify_params sends it

With modify_params on, a trailing tool search turn whose call has a kept result
got a placeholder answer from the factory and went out as a marked tool_use,
but the cache control hook counted marks before that placeholder existed and
skipped the mark, so a request at the cap reached Anthropic with 5 marks and
failed with a 400. The hook now finds client answers on the sanitized messages,
the same list the factory reads.

Also make the replay checks cheaper (prefix check before validation, early
return without provider_specific_fields, and look up client answers only when
a tool call carries cache_control), drop the two audit cells that cover old
gaps outside the tool search fix, and derive the pass-through test timeout
from the graceful stop budget.

* fix(anthropic): keep the duplicate tool result warning out of the cache control hook

The hook finds client answers with only the step of the modify_params sanitize
pass that pairs tool calls with their results, so a request with a duplicate
tool result logs the warning once again instead of once per mark count.

Also restore the Snowflake non-stream and cached-stream tool search cells as
known bugs with pytest.skip instead of deleting them, and put the Anthropic
pass-through test timeout back to 240 seconds.

* fix(anthropic): count cache marks next to a message the pairing step cannot read

With modify_params on and a marked tool call, the cache control hook paired tool
calls with their results before counting. A message without a get method (a
stray string or null in extra_body.messages, or an openai SDK
ChatCompletionMessage) made that pairing raise AttributeError before any
provider call, where main counted the marks and let the request through.

The hook now pairs only when every message can be read the way the pairing
step reads it, and otherwise counts on the messages as sent, like main did.

* fix(anthropic): count cache marks after placing a later system message the way the request builder does

* test(anthropic): cover a leading system prompt and a system message before the answer in the cache mark census

* test(anthropic): align the tool search replay cells with main and cover a system message after the search turn

The malformed kept result cells now expect the unanswered search call to be dropped, as main does since #45882.
The stream cut cell checks streamed tool call names, since the kept search result names get_weather as a tool
reference. The streamed response cache hit cell runs again because #46104 fixed it. The modify_params cap cell
expects the four client marks, since the placeholder answer sends the search call as a plain tool_use with its
mark, and a new cell covers a system message after the trailing search turn in both stream modes

* fix(anthropic): count marks on the raw messages when they cannot be placed, and find client answers once per request

* test(anthropic): cover marked tool calls next to a malformed tool id and a later system message

* perf(anthropic): look up client tool answers only when a marked tool call is a server tool call

Answered ids only decide whether a marked srvtoolu_ call is rebuilt as server_tool_use, so a request whose marked
tool calls are all client calls no longer places system messages or runs the modify_params pairing step to count
marks

* test(anthropic): reach the client answer lookup with a marked search call in the malformed tool id cell

* perf(anthropic): place mid-conversation system messages in linear time for models that keep them

* fix(anthropic): count cache marks with the model's own system message placement and pair tool results in linear time

* test(anthropic): cover modify_params dropping a tool answer that answers no call of the latest assistant turn

* fix(anthropic): count marks with in-place system placement when the model lookup cannot confirm the flag

* test(anthropic): cover a bare model with custom_llm_provider filling the cache mark budget through litellm.completion and Router

* fix(anthropic): give unmapped models the request builder's converting placement and survive any model lookup failure

* test(anthropic): cover an unmapped model name counting cache marks with the request builder's converting placement

* fix(anthropic): count server tool call cache marks the request builder's way only on routes that build Anthropic Messages requests

Databricks, OpenRouter and Bedrock Converse send every marked tool call as is, so the hook keeps the census main uses there. The seeding step carries custom_llm_provider on the injection points when a server tool call is marked, so a bare model name still resolves its route.

* test(anthropic): cover two answered marked server tool calls before a system message on Databricks, OpenRouter and Bedrock Converse

* fix(anthropic): keep main's cache mark count on GitHub Copilot and ChatGPT routes without resolving them, so a sync call with no stored login never starts the device flow

* test(anthropic): cover a marked server tool call reaching the GitHub Copilot and ChatGPT login hosts like an unmarked one

feat(providers): add Inference APIs as OpenAI-compatible provider (#41669)
* feat(providers): add Inference APIs as OpenAI-compatible provider

Registers https://api.inferenceapis.com/v1 as a JSON-configured provider (chat completions and Responses API).

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

* fix(providers): list Inference APIs in Add Model and the provider docs index, add request-level tests

- provider_create_fields.json entry so the Add Model dropdown test passes
- provider_endpoints_support.json (+ backup) entry so the provider docs check passes
- tests now capture the outgoing HTTP request (URL, auth header, body) instead of only inspecting registrations
- drop a redundant comment

* test(providers): inject a recording HTTP session instead of patching httpx.Client

Request-level tests now set litellm.client_session to an httpx.Client with a MockTransport, so nothing is
monkeypatched on a class.

* feat(inferenceapis): add cost map rows for the 12 chat models and test the responses route

Prices and context windows come from https://inferenceapis.com/pricing and GET /v1/models.
Moves the provider test to tests/unit and adds the interactions flag the endpoint matrix now carries.

* feat(inferenceapis): price the vendor's chat model aliases and mark /v1/messages supported

* fix(inferenceapis): serve /v1/messages natively and keep audio routes off the provider

* fix(json providers): send provider-specific params in extra_body and report context overflow as ContextWindowExceededError

* fix(exception mapping): match the Inference APIs overflow phrase instead of any context_length_exceeded substring

* fix(exception mapping): map context overflow to ContextWindowExceededError for Inference APIs only

Providers without their own mapper keep reporting an overflow as BadRequestError, since the router raises a ContextWindowExceededError instead of trying generic fallbacks when context_window_fallbacks has no entry for the group. Adds the integration cells for the provider, its fallbacks, and the extra_body and overflow families.

* test(inferenceapis): hold upstream replies across the worker kill in the chaos cell

A reply the killed worker sent before SIGKILL can lose its queued spend row, which the
product never promised to keep. Holding the upstream until after the kill means only the
surviving worker answers, so every 200 must log exactly once.

* test(inferenceapis): make the chaos cell kill the quieter worker and always release held replies

The survivor now must hold at least one in-flight request, so the burst check cannot pass as 0 == 0, and the held vendor is released on exit so a failed assertion cannot stall the wire server teardown

fix(streaming): keep provider response headers on SDK streaming errors (#41528)
* fix(streaming): keep provider headers on MidStreamFallbackError

A 429 raised while opening a stream is wrapped in MidStreamFallbackError,
which dropped the litellm_response_headers exception_type() attaches to
the wrapped error. retry-after and x-request-id reached callers on the
non-streaming path but not on the streaming one, so retry backoff,
provider request id logging and proxy error headers lost them.

* refactor(streaming): drop explanatory comment from MidStreamFallbackError header copy

* test(streaming): cover sync and async header carry on MidStreamFallbackError

Parametrizes the provider-header test over the sync and async stream
wrappers, and drops the hasattr test, which pinned how the attribute is
stored rather than what any caller observes

* test(streaming): add integration cells for stream-open provider headers

Cover the SDK stream openers (gemini, vertex_ai, codestral, predibase and the
eager providers), the Router stream retry and fallback paths, and the proxy on
both the router and the config-less serving paths, including a mixed burst, a
worker SIGKILL and a SIGTERM restart. Add a helper that boots a config-less
proxy owned by the test
