* test(azure): audit #47348
Add proxy integration tests for #47348's cached Entra token providers and
off-loop token refresh, and fix the token herd the audit found: once the
fetch moved to a worker thread, concurrent cold requests each fetched their
own token. Every cached bearer token provider now serializes its calls so
the first fetch fills the cache and the rest reuse it
* fix(azure): build each cached Entra token provider once under concurrent first calls
lru_cache does not hold back concurrent misses, so worker threads that miss together each built their own credential and token provider, and each fetched its own token. A lock around each provider cache makes the first caller build it and the rest reuse it
* fix(azure): share Entra token fetches only while no valid token is held
Concurrent callers now share one result (or one error) from the cold
fetch, while callers inside the refresh window keep the still-valid
token. The oidc/azure provider build and the client-assertion exchange
are single-flighted per audience, and the shared helpers no longer call
subscripted generic aliases, which crashed on Python 3.10.
* fix(azure): refresh Entra tokens once while other requests keep the valid token
MSAL treats a token with less than five minutes left as expired, so every
request in that window fetched a new one. Now one request refreshes while
the others keep using the still-valid token.
Requests that waited on a fetch that failed retry once through a fresh
fetch instead of all failing with the first error.
Credentials that only implement get_token keep working, and OIDC token
exchanges are cached per scope.
* fix(azure): bound Entra token waits during an outage
Requests waiting on a failed token fetch now retry only when the fetch
before it succeeded, so during an Entra outage later bursts fail after one
fetch instead of two.
Requests during a refresh only get the held token while it has more than
60 seconds left, and a failed refresh falls back to that token instead of
failing its request.
* fix(azure): share one retry per failed Entra token fetch and raise on a failed refresh
Waiters of a failed fetch now retry the flight they joined, so a fast-failing Entra makes one retry instead of one per waiter. A failed refresh raises again instead of returning the held token, which Postgres token auth read as a fresh one. The DefaultAzureCredential fallback reuses one provider per scope.

* test(batches): cover the batch cost poller gaps left after #47190
* fix(batches): keep unbillable batches from blocking file deletes and new-batch polling
The file delete check now ignores batches past MANAGED_OBJECT_STALENESS_CUTOFF_DAYS, a provider 404 for the output object retires the batch, each poll page takes the arrival lane first, a batch expires only after the poller visits it past the cutoff, and the compare-and-swap matches batch_processed instead of updated_at
* test(batches): cover the full arrival page and a failed expiry write in the batch cost poller
Old batches still get polled every other cycle while new batches fill the page, old batches that fill a page never push a new batch out after boot, and a failed stale_expired write no longer stops the rest of the page from being polled
* fix(batches): share the poll page between old and new batches and hold output files until billed
Each lane now gets at least half of the poll page, a lane with nothing left gives its half to the other, and a lane read that resumed mid-lane wraps to the start, so neither old nor new batches can starve the other.
The delete guard applies the 7 day cutoff to input files only. Output and error files stay locked until the batch is billed or retired, and stale_expired rows no longer lock anything.
Only a lasting provider failure expires a batch past the cutoff, so a timeout or a 5xx no longer gives up on a batch that may still bill. Past the cutoff a lasting failure, a lasting cost-tracking failure, or an output file id that never appeared retires a finished row instead of polling it forever.
* fix(batches): retry refused finished batches past 7 days, expire unfinished ones on a failed retrieve
A finished batch the provider refuses after 7 days (rotated key, bucket 403, a 404 that does not name the batch) now keeps retrying so its spend is written once the config is fixed, instead of retiring unbilled. A batch the provider still reports running keeps polling. A batch that is not finished in the database becomes stale_expired once a retrieve fails after 7 days, so an unreachable provider is not polled forever. An S3 NoSuchKey for the output object now counts as gone.
* fix(batches): expire an unfinished old batch only after 3 failed retrieves in a row
* fix(batches): keep retrying an unfinished old batch through timeouts, 429 and 5xx
* fix(batches): wait 3 polls before expiring an old batch whose output id lags
* fix(batches): match a resource id in a 404 message followed by punctuation
* fix(batches): keep refusal and pending-output expiry streaks apart, and void a pending-output retirement on a client write
* fix(batches): give up on unsettled batches past twice the staleness cutoff
Replace the per-reason refusal and pending-output streaks with one give-up age, and inject a clock into the poller and the delete check so tests pin exact age boundaries
* fix(batches): keep polling finished batches past the give-up age so their spend stays recoverable
* test(batches): expect a restarted poller's first page to split between old and new batches
* test(batches): pin the delete-guard tests to a fixed clock and type a new journal list
* test(batches): type the provider helper and the storage 404 cases

* fix(router): pass lifecycle events through on background OpenAI responses streams that cannot fall back
The Router held response.created, response.queued and response.in_progress until the first output event on every /v1/responses stream, so a background run showed the client no response id while it was queued or reasoning. A native OpenAI stream whose upstream echoes background: true now releases those events as they arrive when no fallback, order level or weighted failover could replace it, and once the id is out a later pre-output error is raised instead of starting a second run behind it.
* test(router): type background stream test params and wait on the upstream pause instead of a clock
* fix(router): keep the content-policy note on a released background stream error
* fix(responses): return the routed id from cancel and add the router note only before output
acancel_responses and cancel_responses now re-encode the reply id with the deployment, like get. The released stream's content-policy note follows the held path, which adds it only before output text. Renames _anthropic_messages_order_levels to _stream_order_levels.

* test(responses): audit #47363
Adds integration cells for the input token count paths #47363 changed: the provider id of a managed file and the 403 for another team's file on OpenAI, file_search and additional_tools parity plus cache-mark stripping and untranslatable tools on Claude, and the Bedrock runtime count leaving out the options it refuses.
* fix(count-tokens): reject a lone tool with no chat equivalent before the Claude count call
A Claude input token count whose only tool was mcp or computer_use_preview skipped the pre-call check and went to the provider, so the caller got the provider error instead of the 400 naming the tool. The check now runs whenever a tool would get a placeholder name.
* fix(responses): count a lone Anthropic toolset and name the uncountable tool
The lone-tool 400 now fires only for OpenAI Responses built-in tool types, so a nameless Anthropic toolset still counts. The error says LiteLLM cannot count that tool type for the model. Adds a Bedrock unit cell for the lone-tool 400 and pins the runtime wire test's tool shape per request type.
* fix(responses): take the uncountable tool types from the OpenAI SDK and keep the region hint off LiteLLM's 400
The Responses built-in tool types now come from openai's ToolParam union, so a type the SDK adds is refused before the count call too. The AWS region hint no longer lands on an error LiteLLM raised before calling the provider. Tests cover two more lone types and the hint.
* fix(responses): keep LiteLLM's own list of uncountable tool types and pass a non-string tool type through
* fix(responses): count tool_search and namespace tools the way Claude chat inference sends them
The count refused a lone tool_search with LiteLLM's 400 and sent a lone
namespace raw or squashed it into an empty tool, while Claude chat
inference maps tool_search to Anthropic's tool search tool and unpacks
a namespace into its function tools. Both now go through the
deployment's own map_openai_params, so the count sends what inference
sends, and tool_search leaves the list of uncountable types.
* fix(bedrock): count a Claude request with its deployment's own chat translation
Bedrock invoke and Mantle inference turn a chat tool_search tool into Bedrock's
tool search tool, but the Bedrock counter always translated with the Anthropic
config, so the count answered 400 for a request inference serves.

* fix(count_tokens): keep the framed estimate when a region-less token_count_model cannot count (audit #47441)
* fix(count_tokens): let framing stand in for a shipped token_count_model, keep a configured one's error
The framed local estimate now replaces a 400/404 from any count model the cost map ships, Mantle-pinned rows included, and an admin-set token_count_model keeps its error as the docs say.
* fix(count_tokens): warn with the region when framing stands in for a pinned count model
Test a Mantle row #47441 pinned in its own region, and keep the region hint check on an admin-set count model.
* fix(count_tokens): name the deployment in the framing stand-in warning
* fix(count_tokens): let framing stand in when a cost map count model's region denies the account
A count model the cost map pins to a region can answer 401 or 403 when the
account has not enabled that region or lacks Mantle count access there. With
framing set, the estimate now stands in, as it does for 400 and 404. An admin
set count model and a count model with no pinned region keep the error.
The warning now names the model group, the count model and its region, and
says the proxy falls back to the estimate.
* test(count_tokens): cover framed 401 and 403 from a shipped count model region on the wire

* fix(mistral): replay assistant reasoning as a Mistral thinking chunk
When a client sends back an earlier Mistral assistant turn, its reasoning
(reasoning_content, thinking_blocks, or Mistral's own thinking chunk in
content) now reaches Mistral as a ThinkChunk inside content. The top-level
LiteLLM fields stay stripped because Mistral rejects them with 422.
* fix(mistral): replay reasoning only to Mistral models that accept it
Mistral answers 400 to a thinking chunk on models without reasoning support,
so a mid-chat model switch, a fallback, or Vertex AI Mistral broke once the
replay was added. Gate the replay on the same check reasoning_effort uses and
keep dropping the reasoning for the other models, as before.
* fix(mistral): drop native thinking chunks for models without reasoning and mark the devstral, code agent, small and leanstral aliases as reasoning
* fix(mistral): keep the leanstral rows as on main, since their reasoning support cannot be checked live

* fix(mistral): keep closed false only on the last chunk of a final prefix turn, so an earlier turn no longer gets Mistral's 400
* fix(mistral): drop closed false when merged text follows the thinking chunk, so a prefix turn with text first no longer gets Mistral's 400

* feat(proxy): log one line per token count call
Each count call on /v1/messages/count_tokens, /utils/token_counter, /v1/responses/input_tokens and the Gemini countTokens routes now logs one INFO line with the litellm call id, the requested model, the model the count ran against, the count, the count source and the status code, so it joins the inference call that sends the same x-litellm-call-id
* test(google_endpoints): give the count test's fake request a headers list
* fix(proxy): keep token count log lines one per call and trusted in JSON logs, and log Bedrock native counts
Quote log values that carry whitespace, quotes, equals, or control characters so a model name can't split or forge a line. Let JsonFormatter record extras win over a dict parsed from the message. Log the Bedrock native count-tokens route through the same line.
* fix(proxy): escape braces in token count log values, log the Bedrock model AWS counts, and skip the line when there is nothing to count
* fix(proxy): log the deployment id the count routed to on every token count line
* fix(proxy): log count requests rejected before counting with the status they answer
A count route that rejects a request before the shared count function runs now logs the same token count line with its 400. An unsupported content block on the Messages count route becomes its 400 inside the logged wrapper, so its line says 400 instead of 500. A count that ends in a BaseException other than cancellation logs a 500.
* fix(proxy): compute the Bedrock counted model id only after a successful count
* revert(logging): keep the JSON log formatter's field order as on main
The count line already escapes braces in its values, so the formatter never parses a dict from it. Changing the order for every logger is a separate decision.
mistral/mistral-large-4 and mistral/mistral-large-4-0 still carried the launch sale price (input 6.8e-07, cache read 6.8e-08, output 2.09e-06). Mistral's model card and pricing page now list only the list price (input 1.36e-06, cached input 1.4e-07, output 4.18e-06), so every call was billed at about half its real cost. The test derives expected cost from the row's own prices instead of pinning Mistral's numbers.

* fix(chatgpt): derive Responses session id from prompt_cache_key
ChatGPT partitions the Codex prompt cache by the Responses session-id
header (the Codex CLI sends a stable per-conversation key derived from
prompt_cache_key). The provider only consulted explicit session ids
and otherwise stamped a per-request uuid4, so no turn ever reused the
prompt cache -- 0% cache hits on repeat turns, an order-of-magnitude
quota/cost multiplier on subscription accounts.
Resolution order after this change:
explicit session config (session_id / litellm_session_id /
metadata.session_id) > prompt_cache_key (sanitized with
_safe_header_value) > litellm-internal ids > uuid4.
Two guards, mirroring get_fireworks_session_id:
- proxy-generated session ids (missing_session_id: "generate") are
per-request and are skipped, checked in both "metadata" and
"litellm_metadata" (LITELLM_METADATA_ROUTES, responses included)
- internal per-request ids (litellm_trace_id / litellm_call_id) lose
to a stable conversation key
Supersedes the body-key forwarding of #37630: a random session header
overrides the body key on the provider side, so the header must carry
the caller's key. Related: #29978, #29993.
Verified against a real ChatGPT Codex account: stable session id ->
97-100% cached on repeat turns; random per-request -> 0%.
* style: ruff format
* fix(chatgpt): address review - hash unsafe cache keys, move tests, drop comments
- hash prompt_cache_keys containing header-unsafe chars instead of
mapping them through _safe_header_value, whose replacement char could
collapse distinct keys onto one cache shard and serialize unrelated
requests (greptile review)
- strip the explanatory comment blocks per AGENTS.md comment policy
- move the tests into the existing mapped responses transformation test
file per AGENTS.md test-placement rule
* fix(chatgpt): keep session typing and test diff scoped
* fix(chatgpt): hash surrogate cache keys, type session params, flatten tests
* test(chatgpt): record upstream requests with a mock instead of appending to a list
* fix(chatgpt): keep proxy-mapped session headers ahead of body session_id and ignore non-string cache keys
* fix(chatgpt): hash cache keys with leading or trailing whitespace so the session header stays valid
* test(chatgpt): type the session id test parameters
* fix(chatgpt): keep trace ids copied into litellm_session_id from outranking prompt_cache_key
* fix(chatgpt): mark session ids copied from trace_id so explicit ones keep precedence
* fix(chatgpt): keep the trace-id session marker out of provider params
The marker now uses the _litellm_ internal prefix, so bridges that pass litellm_params back into completion() drop it instead of sending it as a provider param

* feat(rust): one typed decline from core up to each host
Rust core says it cannot serve a request with one Decline that travels
unchanged through llms and inference up to the host. The Python bridge
raises RustBridgeDeclined for it in route_failure before the public
exception mapping, so dispatch falls back to legacy Python instead of
failing the call, and the gateway answers 501. Every route collapses
errors after the send with Error::after_send, which keeps a provider
answer and a response fault as they are and nests anything else as the
source of an invalid response, so a billed call can never read as a
decline. Response-side cases that used to decline are now
ErrorDetail::Unhandled response faults.
The rust-error skill documents declined() as the first question both
boundaries ask, and the Python suites pin that a native decline reaches
the dispatcher before any provider IO.

* fix(router): avoid assistant prefill in Responses fallbacks
* fix(router): keep prefill for Claude fallbacks that take it and skip constrained continuations
A Responses fallback to a Claude model that takes assistant prefill now gets
the partial response as prefill again, so it continues mid-word without the
prompt-shape drift. Every other fallback keeps the request to continue.
A stream cut after text no longer continues when the request constrains its
output (a json_schema or json_object text format, or a forced tool_choice),
since a continued JSON document or tool call would not parse. The client gets
the primary's error, as on the chat path.
The fallback's re-sent leading space at the seam is dropped, and the prefill
shaping runs per deployment after the encrypted reasoning strip, so stripped
reasoning is never replayed.
* fix(router): guard SDK text_format, narrow forced tool_choice, read Claude base_model, and cap Responses continuation output
Cut Responses streams that asked for structured output through the SDK's text_format now surface the primary's
error instead of stitching two models' JSON. Only a required or named tool_choice counts as forced, so allowed_tools
in auto mode and hosted tool choices still continue. A Claude deployment named only through base_model keeps its
prefill continuation, and the continuation's max_output_tokens is lowered by what the cut stream already emitted.
* fix(router): quote the partial's ending in the continue request and surface the primary's error after a cut tool call
* fix(router): stop Responses fallbacks from continuing content-filter cuts and client-run tool calls
A content filter that cuts a /v1/responses stream mid-answer now returns its error, as on chat, instead of letting a content_policy_fallbacks backup finish the filtered text. Shell, apply_patch, computer, local_shell, and MCP approval items count as a started tool call. Chat continuation goes back to treating any tool_choice object as constraining, as on main
* fix(responses): count a stream of tool arguments as a started tool call
* fix(router): let Responses fallbacks continue under allowed_tools auto and after server-run tool calls
A Responses tool_choice of allowed_tools in auto mode no longer blocks the continuation, since the model may still answer in text. Hosted MCP calls and the bridge's server-run tool search no longer count as a started client tool call.

Covers the json_schema envelope edge cases #47478 fixed on the Anthropic json tool path: a key listed only in
`required`, a tool-named wrapper on a stream, non-ASCII and lone-surrogate answers, a stream cut before the tool
block closes (proxy and sync SDK, Anthropic and Bedrock Invoke), and a string `output_format` with and without
`drop_params` on Anthropic and Vertex chat and /v1/messages. The scripted Anthropic peer now refuses a non-object
`output_format` the way Anthropic does

* fix(bedrock): retry without strict when Bedrock rejects strict tool schemas under drop_params
* test(bedrock): cover the strict tools 400 retry under drop_params
* fix(bedrock): anchor the strict tools rejection match and strip toolSpec strict
* test(bedrock): return captured requests from the strict tools test helper
* fix(bedrock): retry without strict only when a tool sent strict to Bedrock
A strict-limit 400 on a request whose tools carry strict: false, or on a model litellm never sends strict to, was sent again with an identical body. The fallback now takes the model and returns nothing unless a tool puts strict on the wire. Also types the fallback test parameter and records the mock transport's requests on the recorder instead of a mutated list
* fix(bedrock): decide the strict retry on the profile's base model and retry grammar timeouts
An application inference profile with base_model sends strict on the wire, so the retry check now resolves the
capability model the way the request transformation does. Bedrock's "Grammar compilation timed out" 400 is a
strict-grammar rejection too, so it takes the same single retry under drop_params.
