feat(redis): serve the router's session pins from a native store (#50870)
Deployment affinity and the complexity router's session and tier pins move
off the router's DualCache onto RouterSessionPinStore, backed by the native
redis-store. The read and claim Lua scripts run byte-identical to main, the
pin read rides the request's pre-call batch, and keys and values keep main's
format.

refactor(router): count the whole router_usage family on the native store (#50862)
* refactor(router): count the whole router_usage family on the native store

usage-based-routing-v2, the model rate limit check (tpm, rpm, tpd, rpd) and the
io-token check (itpm, otpm) count through the native router_usage store, next
to the router core's global_router tpm and rpm. The pick's usage read rides the
native pre-call batch and settles on the batch reply, keeping DualCache's
per-key read throttle, and the success tpm increment rides the native
post-call batch after counting in memory. io-token reservations stash their
counter's fields instead of a Redis key. Redis keys and values are unchanged.

A Redis service event is reported in a context named for whose it is, either
the calling store op's, the request whose post-call batch its deadline sends,
or nobody's for breaker transitions and unscoped calls. The deadline's tag is
built when a post-call declaration arms it, so that flush parents under the
request's span even though auth sets the span after the batch scope opens. An
SDK call anchors the span its caller passed, so its usage reads and io-token
refunds parent under it without a span argument threaded through the family.

* fix(redis): keep an int counter past i64 above the limit instead of wrapping

Number::add summed two ints with plain i64 addition. With Redis off and the OTPM counter at 1, a request with max_tokens=2**63-1 passed the MAX_INCREMENT check, and the memory count wrapped negative in a release build, so it passed admission and let other requests past the cap. Python's int never overflows, so main sees a count above the limit, rolls it back and answers 429

An int sum past i64 now becomes the nearest float, which compares above any limit the way Python's int does. The rollback after such a refusal can leave the count one token low, since the float cannot hold 2**63 exactly

* fix(logging): run every callback under the span an SDK caller passed

Native Redis service spans take their parent from the request span contextvar. The proxy sets it at auth and the SDK router scopes it around the routed call, but a streamed response is iterated after that scope closes, so its callbacks saw no span. Three callbacks reopened the scope from kwargs by hand, and the sync stream path had no wrap at all because its success handler runs on an executor thread

The four Logging handlers now anchor the span from model_call_details around their dispatch, so every CustomLogger callback sees it, streamed or not, sync or async, with or without a Router. The per-callback wraps in lowest_tpm_rpm_v2 and model_rate_limit_check are gone. A span already anchored, as on the proxy, is kept

* test(logging): cover a mid-stream failure, and drop the span wrap in Router._release

The callback span test now also breaks a stream after its first chunk, sync and async, through a custom provider, so the failure handlers the stream wrapper starts on a bare thread are covered too

A probe through the Router showed Router._release only runs inside the routed attempt, where the router has already anchored the span, and never after a stream returns. Its own wrap was a no-op, so it is gone

* fix(router): refuse an io-token reservation past its limit before counting it

The overflow fix let a reservation near i64::MAX become a float, so the count still read above the limit and the request got its 429. But the rollback subtracted the same amount from that float, and with OTPM usage at 40 the count came back as 0.0, so later requests reused capacity already spent

A reservation above its limit now gets the 429 before the store is touched, in the async and sync paths. On main the count went up and straight back down for such a reservation, so the answer and the count after it are the same as main's. Only the usage named in the error message differs, which now shows the reservation instead of the count plus the reservation

* test(redis): send the failed SDK call's refund through a real completion

The refund span test called ModelRateLimitingCheck.async_log_failure_event directly, so it relied on the span wrap that callback used to carry. The Logging failure handlers now anchor the span for every callback, so the test sends a failing litellm.acompletion with the reservation in its metadata and checks the refund's Redis span still lands under the caller's span

feat(redis): serve the health checks' deployment states from a native store (#50357)
* feat(redis): serve the health checks' deployment states from a native store

DeploymentHealthCache reads and writes its one Redis entry through a new
deployment_health store family instead of the router's DualCache, like the
other router families.

* refactor(redis): type the deployment health states in the store

The health store kept a raw Value from Redis to Python and back, so Python re-checked the shape by hand and router-core only got a typed record after a Python pass. The family now has a types.rs with HealthState and HealthStates, the bridge converts through PyData, and the Python store returns DeploymentHealthStateValue mappings

Reads keep main's leniency for records another writer left: extra fields are ignored, a falsy flag is unhealthy and a missing one healthy, a timestamp that is no number reads as 0, and a record that is no dict is dropped alone. A rewrite writes only is_healthy, timestamp and reason

feat(bedrock): search knowledge bases by image and return image hits (#51063)
* feat(bedrock): search knowledge bases by image and return image hits

vector_stores.search and asearch take a query_image (base64 jpeg, png, gif or webp), and query is optional when it is sent. Bedrock sends it as an IMAGE retrievalQuery, and a caller's own retrievalQuery in extra_body still wins

Bedrock IMAGE hits now come back as image content items instead of being dropped. The media type comes from the source file mime type metadata, then the data URI label, then application/octet-stream

A request with both query and query_image, with neither, or with a malformed image gets a 400. So does query_image on a provider without image search, unless drop_params is on. The proxy accepts query_image in place of query on /v1/vector_stores/{id}/search

Spend logs redact image data when prompts are not stored. Emulated file_search skips image-only hits, RAG rerank maps its indices to the text documents it ranked, and the dashboard tester renders image hits

* fix(vector-stores): keep image hits to image searches and reject a caller retrievalQuery

Text searches on a multimodal Bedrock knowledge base return the same text hits as before, so chat, RAG and logging payloads stay unchanged. Image hits come back only when the caller sent query_image

A caller retrievalQuery now answers 400 pointing at query_image, or is dropped under drop_params, instead of replacing the built query unchecked

A file_search chat tool that carries query_image or rewrite_query searches again instead of failing, and a non-string query next to an image answers 400 instead of 500. query_image is keyword-only on search and asearch

* fix(vector-stores): redact query images and keep store search params out of image checks

* fix(vector-stores): redact images nested in extra_body and keep a store's extra_body retrievalQuery out of searches

* fix(vector_stores): keep a caller's image query through store and router params

A deployment's retrievalQuery no longer reaches a routed search, a caller's query fields survive a store's own extra_body, and an extra_body image stops before the provider. file_search forwards rewrite_query, both retrieval query spellings are redacted, and the cost error stops echoing the response when message logging is off

* fix(cost): leave image search responses out of the cost error text

* fix(vector_stores): accept line-wrapped base64 in query_image data

Bedrock takes inlineContent wrapped with \n or \r\n line breaks, as plain base64 writes it, so the check ignores only those before decoding and the data goes to Bedrock as sent

* fix(vector_stores): drop rewrite_query false from the chat file_search tool

False asks for the default search every store already runs, and MongoDB
rejects the field outright, so forwarding it made a MongoDB chat lose the
store's context for a no-op flag. True is still forwarded.

feat(messages): serve anthropic messages on rust only (#51119)
* feat(messages): apply modify_params rewrites on rust

* feat(messages): mint anthropic workload identity tokens on rust

* feat(messages): apply prompt caching injection on rust

* feat(messages): serve the easy python-only detectors on rust

* feat(messages): retry rejected thinking signatures on rust

* feat(messages): serve response cache reads on rust

* feat(messages): retry rejected strict tools on rust

* refactor(messages): delete the python path for anthropic messages

Provider anthropic on /v1/messages is now RUST_REQUIRED, so it runs on Rust
without LITELLM_RUST or litellm.rust(True) and never falls back to Python.
A call the rules would send to Python (a MESSAGES_PYTHON_FEATURES feature or a
detector that raises) gets UnsupportedParamsError naming the feature, raised
from one place in litellm/messages/dispatch.py. Other providers keep the
Python fallback. A call whose arguments the handler signature rejects still
gets Python's TypeError.

Deleted Python code that only served anthropic Messages:
- workload identity in AnthropicMessagesConfig.validate/avalidate (subclasses
  were never eligible; the Rust host mints the token itself)
- the anthropic Foundry beta-row and affinity-base branch in
  async_anthropic_messages_handler, and the "forward" mode of the beta filter
  that only that branch used

The proxy MCP tools detector now uses the light tool precheck so a function
tool never imports the gateway handler, since a raising detector now refuses.

* feat(messages): forward message threads on rust

The Rust path for anthropic /v1/messages dropped the thread body field, so
a create or continue turn reached Anthropic without its thread or the
message-threads-2026-08-12 beta. It now matches the Python handler from
#50976:

- the host forwards thread with the other body params
- a non-null thread adds the message-threads beta
- a well-formed continue turn keeps advisor blocks in history and derives
  no compaction, per-turn-control or tool-change beta from its messages
- the recorded httpx_response carries the request that was sent, for JSON
  and streamed calls, so the proxy's thread ownership hook resends the
  create turn's betas on a continue as it does for Python

Upstream error.details already reached the exception message unchanged, so
thread_not_found relays and keeps the deployment out of cooldown on both
paths. Parity cases cover create, continue, streaming, sync, retries,
thread_not_found and the ownership hook round trip.

* feat(messages): serve mock responses on rust

* feat(messages): send caller clients and unsupported tls through python on rust

* feat(messages): run pre-request hooks on rust

* feat(messages): run agentic loop hooks on rust

* feat(messages): run the safeguards classifier on rust

* feat(messages): run registered interceptors on rust

* fix(messages): match python stream cache gate, logging and interceptor order on rust

Store a streamed Messages response in the cache only when Python would: a
message_stop event line, no provider error frame and at least one frame with
output. Leave dict results untouched by mark_rust_response so hidden params
never reach result dicts, logging objects or hook digests. Ask interceptors
whether they handle the call after the cache lookup, not at decode time, so a
cache hit never calls can_handle. Emit the track_llm_api_timing service event
for the provider exchange. Bill and log a stream superseded by a router
fallback as the failure of its error frame, with the partial usage warning.
Hand litellm_logging_obj to deployment pre-call hooks as @client does, so the
autorouter baseline cache sees retried requests.

* fix(messages): forward python-only json values to anthropic as python does

Accept any max_tokens, sampling scalar and messages collection that
Python main accepts, and carry values serde_json cannot hold (ints beyond
64 bits, NaN and infinities, strings with lone surrogates) as validated
raw JSON leaves written back verbatim on the wire, so the upstream body
matches Python's json.dumps

* fix(messages): match python's body reads, error bodies, encoded heads and tls warnings on rust

* fix(messages): log python's plain provider header names on rust streams

* fix(messages): match python's request params, logged params and validation on rust

Read a non-bool stream by Python truthiness and send it as given, log the
caller's stream flag as Python's handler does, raise the raw Python errors
main raises for malformed messages, tools, model_info and hook-set
litellm_params or providers, read the tool custom-field drop from
drops_unsupported_params, log the caller's nested fields that
additional_drop_params strips and the Python values of raw JSON leaves,
keep a missing stop_reason absent, and map provider-config rejections
(missing max_tokens, unknown reasoning effort) as Python's HTTP handler
maps them, with Python's text, effort order, model and provider

* fix(messages): match python's tls curve names, redirects, auth token, header encoding and timeouts on rust

* fix(messages): match python on hooked streams, empty cache writes and mcp cache hits

* fix(messages): join already buffered stream reads and trim the env api key as python does on rust

* fix(messages): deliver stream bytes read before a cut, keep wide reply numbers and follow python's redirect limit on rust

A stream cut by a transport error now hands the caller the bytes already
buffered before raising, as aiohttp does for a caller that reads them before
the event loop sees the cut, so the frames and their usage reach the caller and
the failure log. Provider replies keep integers wider than 64 bits exactly and
read numbers that overflow a float as infinity, through the response, the
response cache and the logged result. The provider client follows up to 20
redirects as httpx does, and running out raises Python's text. A
provider_specific_header value the ascii codec cannot encode fails before the
send like a caller extra header. The deployment success hook gets the stream as
AnthropicMessagesStreamingResponse, as Python's handler hands it.

* feat(messages): serve proxy mcp tools on rust

* test(messages): cover hook, agentic and interceptor edge cases in the parity suite

* fix(messages): keep provider raw-json marked strings, drop non-string tool_result texts and key clamped streams as python does on rust

* fix(messages): match python's api key encoding, malformed api_base and string provider header errors on rust

A header value Python's client cannot encode as ASCII now fails before the send
whichever header carries it, so a caller api_key with a non-ASCII character
raises Python's InternalServerError instead of a raw UnicodeEncodeError after
the reply. A caller api_base without an http(s) scheme, or with whitespace,
control or non-ASCII characters, is sent through Python's client at the URL
Python builds, so its relative-URL and invalid-URL errors match, and a base
urlsplit cannot split raises Python's bare ValueError before the send. A
provider_specific_header of the wrong shape is scoped through Python's
ProviderSpecificHeaderUtils first, so a plain string raises Python's
AttributeError.

* fix(messages): keep integer temperature and top_p digits a float cannot hold and raise python's typeerror for a string max_tokens while capping the thinking budget on rust

temperature and top_p now deserialize through recognized::exact_float, which keeps an integer
where float(n) != n (beyond 2**53) as an unrecognized value with its exact digits, so it is sent
upstream and logged as the integer python forwards, and comparisons still go through scalar.rs

cap_thinking_budget_to_max_tokens compares max_tokens <= 1024 first, so a max_tokens python
cannot order against an int (a string, list or dict) raises TypeError "'<=' not supported between
instances of 'str' and 'int'" in both the reasoning effort translation and the adaptive effort
reshape. rust now returns ErrorDetail::UnorderableTypes there, the bridge raises it as a python
TypeError marked as a late rejection, and map_failure hands it to the caller unmapped

* test(messages): format the non-string tool_result parity helper

* fix(messages): flag and log the call before python's pre-send raises on rust

The bridge now hands settings() and map_failure() whether the call is async.
A provider_specific_header of the wrong shape sets the aanthropic_messages
flag before re-raising, as Python's handler has already flagged the call. A
base urlsplit cannot split also logs the resolved model, provider and optional
params first, as Python raises it only after its logger is updated. The
TypeError raised while capping the thinking budget for a string max_tokens
sets the flag too

* feat(messages): serve the web search short-circuit override on rust through the intercept host call

* fix(messages): give the web search entry kwargs its mutable-ok reason

* test(messages): drop the body hook gap the rust short-circuit closes

* fix(messages): name the partially unknown handler types on the short-circuit host call

* fix(router): send managed batch uploads to batch deployments when a chat deployment has a lower order

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.

fix(router): re-check and reserve per-model rate limits on fallback targets (#50994)
* fix(router): re-check and reserve per-model rate limits on fallback targets

A provider error fallback handed the caller the fallback model group without
its per-model TPM/RPM limits ever being checked. The router gets a
fallback_rate_limit_check hook next to fallback_budget_check, the proxy wires
it to the v3 limiter, which reserves the target model's per-model descriptors
before each fallback hop and skips targets that are over their limit.

* fix(router): dedupe a repeated fallback target before the reserving rate limit check

chain like ["B", "B"] reserves B once. The deprecated settings parity test

* fix(router): sync responses() applies the Router's num_retries and fallbacks

Sync Router.responses() made one attempt and raised, while aresponses()
retried and fell back on the same Router. The sync plan now walks retries
and fallbacks like the async one, stamps the deployment's num_retries on
the error the same way, and the SDK no longer nests its own retries under
the Router's for sync generic calls

Fixes #49938

* fix(router): sync generate_content() retries and falls back through the Router

Reading litellm_metadata in the SDK retry check left sync generate_content
with no retries at all, since its Router plan made one attempt and the inner
completion() call stopped retrying. Sync generate_content and
generate_content_stream now walk the Router's retries and fallbacks like
their async versions, so retries are neither lost nor nested

feat(proxy): let teams use their own allowed S3 buckets for batch files (#50571)

A team's metadata can now list allowed_s3_buckets. Keys on that team may send one

POST /v1/batches, and the upload and batch-create handlers check the bucket against
the team list plus general_settings.allowed_client_side_s3_buckets. The early auth
body check still rejects bucket fields on every other route and method

through an internal stored_s3_bucket_name param, so content, retrieve, delete and the
batch cost job can read files written to a request-chosen bucket. Callers can never
send that param, and files in the model bucket resolve exactly as before

* test(proxy): assert outcomes in team bucket tests and type the managed content read

Gives the admit-only tests a real assertion, has the refresh test check what the caller gets back, and narrows the provider file id before reading its bucket so the type gate stays at its base count

* fix(proxy): keep team S3 bucket lists proxy-admin only and read prefixed request buckets back

A team admin allowed to edit team metadata could add any bucket to the team's allowed_s3_buckets, so the key now sits with the other proxy-controlled team metadata keys. The stored bucket for a managed S3 file now keeps any prefix that comes before LiteLLM's own path, so a file uploaded to a request bucket like team-bucket/tenant reads, refreshes and deletes from that prefix

* fix(proxy): keep the request's approved S3 bucket when merging deployment credentials

Model-routed uploads and batch creates merge the deployment's credentials into the request, and that merge let a deployment's s3_bucket_name or s3_output_bucket_name replace the bucket the request had already been approved for, so Bedrock wrote to the deployment bucket. The merge now keeps any bucket the request carries and fills it from the deployment only when the request has none

* fix(proxy): keep the request bucket only on upload and batch create, not on reads

The previous commit let a request's S3 bucket win over the deployment's on every credential merge, which undid #47496 on reads, where the deployment's bucket bounds which buckets a model-routed file id may point at. Deployment credentials win again by default, and only model-routed and provider-only upload and batch create opt in to keep the bucket the request was approved for

* fix(proxy): only proxy admins can set a team's allowed_s3_buckets

Org admins and users allowed to create teams could put any bucket on a team's allowed_s3_buckets through /team/new or a team update, which grants that team the proxy's AWS access to the bucket. The key now goes through the same proxy-admin-only metadata check as the batch limits, so only a proxy admin can add, change or remove it, and resending the stored value still passes

fix(router): hold the registry lock across router-core writes and mirror reads (#50933)
* fix(router): hold the registry lock across router-core writes and the mirror reads at their positions

A registry lookup returns positions in router-core's list and the host reads its mirror at them,
while an upsert wrote router-core and read the mirror back unlocked. A read on another thread in
between got an IndexError past the mirror, or after a removal the neighbouring model's entries

* test(router): cover the registry lock's read and write paths

Move the concurrent-read regression into the registry writes characterization, drop the
explanatory lock comments and the unused litellm-model lookup

fix(router): count a Responses WebSocket turn's tokens before the next turn is admitted (#50730)
* fix(router): count a Responses WebSocket turn's tokens before the next turn is admitted

* fix(responses): forward and log a finished websocket turn when its early count fails or is cancelled

A usage payload the parser rejects no longer stops the relay before the terminal event reaches the client, and a client that leaves while the turn is being counted still gets the turn logged. A cancelled early count now clears its counted-tokens marker so the logging callback counts the turn in full.

* fix(responses): finish a turn's early token count when the client leaves

A client that left while a finished turn was being counted cancelled the count halfway. The router's count could be written with no marker, so the logging callback counted the turn a second time. The count now runs to the end before the turn is logged, and the failure path goes back to clearing only on errors

* fix(router): count one router request per Responses WebSocket turn

A socket whose finished turns each counted their own request in router
usage no longer adds one more request when it closes, so N turns count N
requests, as N HTTP calls do. A socket with no counted turn still counts 1

* fix(proxy): keep router usage markers out of pass-through client metadata and ClickHouse rows

fix(proxy): serve Codex its own Bedrock catalog entries for Bedrock deployments (#50743)
* fix(proxy): serve Codex its own Bedrock catalog entries for Bedrock deployments

Codex builds separate catalogs for Bedrock's runtime and Mantle endpoints that turn off what Bedrock does not support yet. A model whose deployments run on Bedrock now takes its entry from those catalogs, vendored from Codex 0.166.0, instead of from Codex's OpenAI catalog.

* fix(proxy): keep Bedrock catalog entries from Codex releases that cannot decode them

codex debug models leaves out fields such as supports_parallel_tool_calls that Codex releases before 0.148.0 require, so a Bedrock entry now needs at least 0.148.0 as well as its source entry's minimum.

* 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.

fix(router): merge default metadata under the request's instead of replacing it (#50700)
* fix(router): merge default metadata under the request's instead of replacing it

* fix(router): join default metadata tags after the request's tags

A router default_litellm_params.metadata.tags list replaced the request's tags, so the deployment and credential tags the router adds never reached the logged request tags. Default tags now follow the request's tags, skipping ones already present, like the proxy's key tag merge

* fix(router): keep masking a router default turns on

Merging default metadata under the request let a caller's mask_input or mask_output false switch off masking an admin set in default_litellm_params.metadata. A masking flag the default turns on now stays on, and a caller can still turn masking on. Also gives this PR's test suppressions a reason and adds a missing blank line

* fix(router): keep the router's cache namespace and drop malformed caller tags and dicts

A caller's metadata.redis_namespace no longer beats a router default, so it
cannot pick another tenant's cache partition. A caller tags value that is not a
list, or a non-dict value under a dict default, is treated as absent the way the
proxy's merge_tags treats malformed tags, so the router defaults still apply.

* test(router): check that mask_output stays on when the router default turns it on

* fix(router): keep a router default guardrail whatever guardrails the request lists

* fix(router): keep the admin's settings for a router default guardrail when the caller lists it

* test(router): check that a router default guardrail entry keeps the admin's settings

* fix(router): keep a router default private Langfuse trace private whatever the caller sends

* fix(router): keep a router default function such as langfuse_masking_function over the caller's value

* fix(proxy): price expanded wildcard /model/info rows as the model their calls route to

* fix(proxy): read wildcard routing through the router registry entry points

* fix(proxy): price a wildcard row only when the router sends its name there

Use the router's own route candidates for the listed name, so an alias, a routing group, a more specific pattern, or a team's own deployment keeps a wildcard row unpriced

* fix(proxy): show no price on a wildcard row whose calls go to another deployment

* fix(proxy): keep the listed price on catch-all wildcard rows and match the edit path to the read path

* fix(proxy): price a wildcard row aliased to a sibling name as the alias target

* fix(proxy): price wildcard rows through the caller's alias renames and show nothing for rows another deployment takes

* fix(proxy): keep same-model wildcard row prices, skip deleted team aliases, use the caller's team

* fix(proxy): keep live team aliases when skipping deleted team alias targets

* fix(proxy): show no wildcard row price when the same-model deployment serving it sets custom rates

* fix(model_info): recognize a replayed wildcard row on a worker that has not loaded the wildcard

* test(proxy): feed wildcard discovery real provider data in model info tests

* fix(proxy): price a wildcard row another deployment serves as the model its calls bill

A row whose calls reach another deployment now shows that deployment's model
and limits, and goes blank only when those deployments bill more than one model
or declare their own rate. A name no route serves keeps its own price, and a
replayed row stores none of the metadata it showed.

Drop the router's per-call scan of every deployment for a team key, since the
team and name indexes already cover those names.

* fix(proxy): price a wildcard row aliased to an aliased group as the group its calls reach

An alias target that is itself aliased onward listed the onward group's deployments too, so the row showed no price while calls billed the first target's model. The billed model now comes only from the route candidates

* fix(proxy): price a wildcard row billed by another deployment without the wildcard's base_model

A row aliased to another deployment priced as that deployment's model, but the lookup still swapped in the source wildcard's base_model, so the row showed a rate its calls never bill

feat(proxy): total_timeout bounds a whole non-streaming request (#50496)
* feat(proxy): total_timeout bounds a whole non-streaming request

A `total_timeout` body field or `x-litellm-total-timeout` header (the header wins) gives a non-streaming
/v1/chat/completions, /v1/messages or /v1/responses request one budget for preparation, retries,
moderation and post-call processing. Past it the proxy answers 408 and cancels the upstream call, and
a retry whose backoff cannot fit ends early with the error it would have retried. A body value on a
streaming or background request is refused with a 400, a header value leaves it unbounded. A timed out
request is billed like a client disconnect.

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

* fix(proxy): ignore any total_timeout header on requests it cannot bound, and never interrupt pre-call admission

A globally configured x-litellm-total-timeout that is malformed no longer fails the streaming and
background requests it is ignored on. The deadline holds while pre-call admission runs, since admission
reserves shared quota before it records it, and an expired deadline then ends the request before
dispatch, where the failure path hands the reservation back.

fix(router): a cancelled or retried attempt releases its io-token reservation and least-busy count (#50486)
* fix(router): a cancelled or retried attempt releases its io-token reservation and least-busy count

A routed attempt cancelled mid-call (client disconnect with cancel_on_disconnect) kept its ITPM/OTPM
reservation and its least-busy in-flight count, and retries sharing one logging object leaked the
count of every attempt after the first. Each async attempt now runs under its own attempt id, so the
attempt and its own callbacks release what it holds exactly once, in tasks a cancellation can't stop.

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

* fix(router): settle an io-token reservation once even through a logged copy of its metadata

/v1/messages and /v1/responses stash the reservation in litellm_metadata, which the logging object
copies. A cancelled attempt refunded it, then the proxy's failure logging refunded the copy again.
Each stash now carries an id, and a reservation already settled under that id is not settled again.

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

* fix(router): keep spent tokens counted, refund a previous attempt's stash, and fit every call in flight

A request cancelled after its provider answered now keeps the tokens it spent counted instead of
refunding them. A retry refunds the reservation its previous attempt left behind even though it runs
under a new attempt. The least-busy reservation store holds twice the keys, since each call in flight
now keeps one more.

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

* fix(router): never evict a settled reservation id before its counters' window has passed

Settled ids lived in a capacity-bounded cache, so past 10,000 settlements in two minutes a late copy
of an evicted reservation was refunded a second time. They now leave only when their window expires.

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

* fix(router): start releases eagerly and keep attempt settlement out of router_utils

A release that never waits (an in-memory counter) now finishes before its caller goes on, as it did
when the caller awaited it inline, so a websocket turn's usage is counted by the time its logging is
flushed. Each reservation carries its own id, and the attempt settlement module moves to
litellm_core_utils, since litellm/utils.py may not import from router_utils.

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

* fix(router): count only finished answers as spent, and declare the least-busy redis family

A stream's wrapper returning is not an answer: a stream cancelled before its first chunk now hands
back its whole reservation. Only a non-streaming result marks its attempt as answered. The module
level least-busy shared decrement carries its redis family, as every direct redis caller must.

feat(router): add the Switchyard stage router as an auto router strategy (#50407)
* feat(router): add Switchyard Stage Router strategy

* feat(router): decision-model classifier and safer fallbacks for the Switchyard stage router

Moves to nemo-switchyard 0.4.0a1, which adds decision-model classifiers and makes
ModelCall.respond and fail async. The classifier is now a tagged union of an LLM
judge and a decision model, and decision calls go through the router's adecisions
so any decisions provider works. Algorithm misbehavior and library errors route to
the capable model instead of failing the request, and the session id plus client
session headers are always passed so capable holds apply without a classifier

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

* fix(router): keep the Switchyard router inside the type-check gate

The gate's environment did not install the optional switchyard extra, so every
libsy symbol counted as Unknown. nemo-switchyard joins proxy-dev like the other
optional runtime packages, and imports go through switchyard_rust.libsy, which
ships py.typed. Step handling moves into helpers so no Final is rebound in the
loop, and the dashboard API types are regenerated for the new routing fields

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

* fix(router): route Switchyard on every endpoint and reject unsafe router saves

The router now passes each request's call type to routing strategies, and
Switchyard converts the request to chat messages with the existing converter for
that call type before translating it. /v1/messages turns with tool or thinking
blocks used to fall back to the capable model, and now route on their signals.
The Anthropic converter can keep tool_result.is_error on an analysis copy, so
Switchyard sees tool failures there, while requests sent to models never carry it

Saves of a strategy router that lists itself now fail with a 400 instead of a
500 with a dead row, the capable and efficient models must differ, judge and
decision calls are not retried before failing open, the Switchyard routing
fields are classified for redaction, and the edit dialog returns the saved
router instead of the stale one

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

* fix(router): catch self-routing on patch and rename, and trim Switchyard tests

The self-routing check now reads the stored params through the decrypting
helper and runs when a patch carries no litellm_params, so a PATCH that points
a router at itself or renames it onto one of its targets returns 400 instead of
a 500 with a dead row. The Switchyard tests share one transcript builder and
router fixture, and reformatting noise in unrelated test files is reverted

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

* refactor(ui): make Switchyard a strategy in the existing auto router form

Switchyard is now a card in the existing strategy picker. Picking it swaps the
tier and classifier fields for the Switchyard fields, and the shared name, team
and save button create it through one submit branch, the same flow as the other
strategies. The separate add form, the extracted picker and the hidden-form
swap are gone, and the edit dialog keeps its own Switchyard form

The judge's session_affinity and message_hash_fallback settings are removed,
since Switchyard rejects both for the stage router

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

* fix(ui): accept partial tool semantics and show server errors on model edit

The Switchyard tool semantics field rejected mappings that list only some
categories, although the server accepts them. Model PATCH errors were
reduced to a generic message, so it now goes through the shared API client
like model create and surfaces the server text

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

* feat(ui): show the routing strategy picker up front in the auto router form

Every strategy was hidden behind an Advanced configuration link, so the
quick setup read as the only option and never said it creates a heuristic
router. The picker now always shows with Heuristics as the labelled
default, the quick setup sits under it, and picking another strategy opens
that strategy prefilled with the chosen models

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

* fix(ui): show the server's reason when a model settings or API key update fails

Both screens replaced the rejection with a fixed message, so a 400 such as
a router routing to itself read only as a generic failure

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

* feat(router): route Switchyard on the Rust router core

main replaced the Python router core with the Rust one, which left
Switchyard routers registered nowhere. Register them with the other
pre-routing strategies, hand each strategy the endpoint the request came
through, and evict Switchyard routers on reload and delete like the rest

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

* fix(router): scope Switchyard sessions per API key and fix review gaps in the Switchyard form

Switchyard session state is keyed by a hash of the caller's key hash and session id, and client
session headers no longer reach Switchyard unscoped. The add form carries the quick setup models
into Switchyard, sends the team and access groups, clears a stale tool semantics error, and the
schema reads API-saved configs with nulls and structured decision instructions

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

* test(router): make the Switchyard test folder a package

* fix(router): read the Switchyard session key hash only from the proxy's own metadata

fix(router): count embedding batches per input in pre-call checks (#49851)
* fix(router): count embedding batches per input in pre-call checks

Embedding input lists went through the Responses input transform, which
calls .get() on each item, so every list-input /embeddings call logged
"failed to count tokens" and skipped the context window check. Lists of
texts, token IDs or token ID lists now count as their longest input,
since an embedding model's context window applies to each input on its
own

* fix(router): keep empty and boolean input lists on the Responses count path

An empty list carries no embedding evidence, and counting it as a zero
token batch skipped the instructions and tools of an empty Responses
input. Boolean lists are not token IDs

* fix(router): honor disable_token_counter for token ID embedding input

Text inputs already counted as zero through token_counter when token
counting is disabled, while token ID inputs were still measured by
length and could be rejected. The router reads the flag through its
dynamic config like its other process settings

* refactor(router): type the embedding count helper with a read-only sequence and final locals

* fix(router): count embedding batches per input on the media-free text projection

The per-input count now runs on the text projection from the embedding
media split, so data URIs a deployment embeds as media keep the media
path and only text items are checked against the context window. A
caption next to an image is checked on its own, and a text-only
deployment still counts an image data URI as text

* fix(router): keep embedding images out of the pre-call count only on image backends, and skip tokenizing inputs that fit by bytes

Media leaves the embedding count only when every deployment in the group declares image embedding input, so a text-only backend still counts a data URI as text and an image backend outside the TPM media list no longer gets a false 400. A text no longer than the smallest window in UTF-8 bytes counts as its byte length without the tokenizer, since a token is never shorter than a byte.

* fix(router): keep embedding images out of the pre-call count when any backend in the group embeds images

Mark Cohere embed-english-light-v3.0 as embedding images, as its v3 siblings are.

* fix(router): check embedding text batches only with an exact OpenAI tokenizer

litellm's default tokenizer counts non-English text several times higher than
non-OpenAI embedding providers do, so counting batches with it refused inputs
the provider accepts. Text batches on those groups now stay unchecked as at the
merge base, without the error log. Main's per-provider media split and the
cost map are restored, so strings and embedding media keep main's path.

* fix(router): count long embedding batches in slices so chat counts do not wait behind them

A text batch is now tokenized in slices of 65,536 characters, each its own offloaded call, so the FIFO count limiter can serve a chat count between slices. The no-OpenAI-tokenizer rule for text lists moved into the pre-call check, so RoutingContext.count_pre_call_check_tokens counts a text list by its longest text.

* fix(router): read embedding media off the event loop and wait on the count limiter in the fairness test

feat(proxy): mixed Codex model picker and LiteLLM routing on native codex routes (#49408)
* feat(proxy): mixed Codex model picker and LiteLLM routing on native codex routes

The native Codex catalog now lists the key's other chat and responses models after
ChatGPT's, within Codex's catalog size limit, and drops the ETag so the merged list
refreshes on Codex's timer. A request for a model configured by exact name on another
provider goes through /v1/responses without the ChatGPT bearer or account header,
while ChatGPT names and wildcard-only matches keep the subscription passthrough.
Reasoning items another provider produced are dropped before forwarding to ChatGPT.

* fix(proxy): keep Codex's picker from turning reasoning off for LiteLLM models

Codex fills a missing default_reasoning_level with effort "none" when a model is picked in /model, while
`codex -m <model>` sends no effort at all. A thinking-only provider model then answers 400. On the native
/backend-api/codex/responses route, drop effort "none" for a LiteLLM model whose catalog entry names no
default, so the provider applies its own default exactly as `codex -m` does

* fix(proxy): harden Codex mixed-model routing on the native ChatGPT routes

Keep the ChatGPT credentials out of hook raw headers on the inner /v1/responses
request, route to LiteLLM and merge LiteLLM catalog rows only for keys that may
call /v1/responses, drop unpersisted reasoning ids on the passthrough when store
is not true, keep any slug the caller's ChatGPT account lists on the subscription
via a shared account catalog cache, and keep X-Models-Etag for keys whose catalog
added no LiteLLM rows. The guide covers the new behavior and the /v1 wildcard
precedence over a catch-all deployment.

* fix(proxy): keep Codex's native route on the subscription when the account list is unknown

A name OpenAI lists for the caller's ChatGPT account now goes to LiteLLM only when the
account's list is known and leaves it out. A failed catalog read is remembered for 60 s and
the Codex version comes only from a User-Agent whose product matches the originator header.

The merged catalog serves a stable ETag digest of OpenAI's ETag and the key's LiteLLM rows,
and /responses replaces X-Models-Etag with the same value, memoized per key for 300 s, so
Codex stops refetching or dropping its catalog cache.

LiteLLM-routed native replies wrap their reasoning with the model id, so an OpenAI or Azure
blob is dropped before chatgpt.com and unwrapped for LiteLLM, and the chat-completions bridge
decodes wrapped thinking blocks with their signature.

The access-group recipe uses chatgpt/ model names so /v1 routing does not change, and the
native route checks the chatgpt/ form of a name the key holds only through that group. A
none reasoning effort is dropped only under drop_params. The guide covers app tools, every
routing case, and the ETag, and the catalog logs how many models the byte limit left out.

* fix(fireworks_ai): move Codex additional_tools items into tools on the Responses API

* fix(proxy): keep Codex native turns working when the key's model listing fails

A listing callback that raises no longer turns chatgpt.com's catalog or
responses answer into a 500. The catalog keeps upstream's body and ETag, and
responses keep upstream's X-Models-Etag.

Under drop_params, a `none` reasoning effort is now dropped only when a
candidate deployment does not explicitly support it, so an alias to a model
like openai/gpt-5.4 keeps it.

The account slug list and its unavailable marker are keyed on the account id
plus the caller's ChatGPT Authorization header, so a failed fetch with one
bearer cannot turn off LiteLLM routing for another caller on the same account.

The auth step checks the Codex route before importing the Codex module.

* fix(proxy): keep Codex model switches working across LiteLLM providers

On the Codex native route, a LiteLLM model now gets only the encrypted reasoning every deployment it can route to is able to decrypt, so ChatGPT or another deployment's blobs no longer make xAI answer 400

Codex additional_tools items are hoisted into tools for every provider except the OpenAI API, and namespace tools become flat tools named mcp__docs__search, the shape xAI accepts

A JWT caller's models ETag is cached on a hash of its LiteLLM credential, so ChatGPT turns stop rebuilding the catalog rows

* fix(proxy): keep Codex namespace tool calls intact across LiteLLM providers

Fireworks and Bedrock Mantle accept Codex namespace tools natively, so the
native route now hoists them without flattening, like OpenAI and Azure and
the chat completions bridge. Other native Responses providers still get
flat names, now built with the bridge's namespace_tool_name_map, and each
function_call they return gets its tool name and namespace back in the
non-streaming body and in streamed output_item.added, output_item.done,
and completed/incomplete/failed events. Every other event passes through
unchanged

* fix(proxy): bridge Codex turns for providers whose Responses API rejects Codex tools

Codex sends its freeform exec tool as a custom tool on every turn, and xAI's
Responses API answers 422 for custom, namespace and additional_tools shapes.
On the Codex native route, a model whose deployments include a native
Responses provider other than OpenAI, Azure, Fireworks or Bedrock Mantle now
asks for the chat completions bridge with use_chat_completions_api, which
already turns custom and namespace tools into functions, hoists
additional_tools, and puts the namespace back on each returned call

OpenAI and Azure still get the request unchanged, and Fireworks and Bedrock
Mantle still get it on their own Responses API with additional_tools hoisted.
The route's namespace flattening and the response-side namespace restore are
removed, since no path sends flattened names anymore

* fix(proxy): drop reasoning ids a Codex turn's LiteLLM target cannot resolve

A reasoning item another deployment produced, replayed with store false and no blob the
target can decrypt, now reaches the target as its readable summary without id or status,
and is dropped when nothing readable is left. OpenAI answered 400 on the status field and
404 on the id for a glm-5p3 item replayed whole to an openai deployment. Same-deployment
replays and stored conversations keep the item whole

* refactor(codex): reach encrypted reasoning stripping through the router registry

The Codex route read Router.optional_callbacks and imported EncryptedContentAffinityCheck from
litellm.router_utils, which the router surface fence forbids outside the router. RouterRegistry
gains decryptable_reasoning(model_group, request_input, targets), which keeps the same rule: with
encrypted content affinity on for the group, reasoning one target can decrypt stays, otherwise
every target must decrypt it

* fix(proxy): keep Codex's priority tier off LiteLLM rows in the native model catalog

* fix(proxy): drop Codex's none effort for an alias whose native entry names no default

* fix(proxy): start a native Codex alias at its pinned reasoning effort and build the catalog off the event loop

* test(proxy): map the pinned reasoning efforts field in the router registry stub

* fix(proxy): honor admin-only /v1/responses and keep Codex's default tier off native aliases

Codex native routes now send a key to LiteLLM only when admin_only_routes allows it,
a native alias with configured service tiers starts with no tier picked, and the
account slug cache declares its Redis key family.

* fix(proxy): check the key's tool allowlist on native Codex LiteLLM turns and additional_tools items

* fix(proxy): check vector store grants on file_search tools inside additional_tools items

A Responses request can define file_search inside an additional_tools input item, which the native Codex route hoists for LiteLLM-served models and OpenAI runs as is on /v1/responses. The vector store check now reads those tools in both strict and legacy modes. The input item scan uses a Mapping guard instead of a pydantic error per item, since auth now runs it on every list input.

* fix(proxy): apply the proxy-wide allowed_routes to LiteLLM models on native Codex routes

* fix(proxy): cap native Codex account catalog reads per LiteLLM caller before rate limits apply

* fix(guardrails): check additional_tools items next to top-level function tools in tool_policy

ToolPolicyGuardrail read tools from the request body only when no top-level
function tool existed, so a blocked tool defined in an additional_tools item
reached Fireworks once the Responses transform moved the item into tools after
the pre-call hooks. Check every list on each request, including namespace
members inside items.

* fix(router): serve decryptable_reasoning from the Rust core's optional checks

The merge with main removed the Python router core, so the registry's host has no
optional_callbacks and no routing context, and native Codex requests with encrypted
reasoning raised RustCoreUnsupported. The filter now lives with the optional checks,
which own both. The ported pinned_reasoning_efforts field gets a test on the Rust core

Also give the static litellm.Router a declared constructor. Since the Python core was
deleted a bare __init__ assignment reads as RustCore's, so every Router(model_list=...)
is a type error and make lint fails on main. TYPE_CHECKING only, no runtime change

* fix(proxy): check the budget of a saved alias target on native Codex LiteLLM turns

Native /backend-api/codex/responses binds {endpoint}, so auth skipped the key's or team's model_group_alias and read budgets on the requested name, while the later /v1/responses handoff served the target unchecked. Auth now resolves the alias on a turn that routes to LiteLLM, as it does on /v1, and leaves ChatGPT-only names on the subscription. Also makes the tool_policy tests build a real ToolPolicyRegistry and type their fixtures.

* fix(proxy): keep a name the ChatGPT account lists on the subscription despite a saved alias

* fix(codex): keep LiteLLM keys off ChatGPT, enforce tool policy on namespaces and pin reasoning on aliases

Auth no longer asks ChatGPT for the account's model list when the bearer is
missing or is the LiteLLM key, so a key sent as the bearer never reaches it.

tool_policy now reads the members of a top-level namespace, which is where
the native route's hoist puts them.

A global alias now reads encrypted content affinity from its target group.

A non-list top-level tools value and a non-string function name now reach the
provider, which refuses them, instead of raising a 500.

The catalog ETag no longer depends on the order a process iterates priced
service tiers in, so workers and pods agree on it.

* fix(proxy): list a team's models in the order the team set them

get_team_models built the names in a set, so each process listed a team key's models in its own hash order and the native Codex catalog sent a different row order and ETag from each worker

* fix(proxy): apply JWT route policy before native Codex routes serve LiteLLM models

A standard JWT caller now gets a LiteLLM model on /backend-api/codex/models
and /backend-api/codex/responses only when the JWT auth flow would admit a
direct /v1/responses call for that model, so team_allowed_routes,
admin_allowed_routes and RBAC route limits hold on the handoff too.

The Fireworks Responses transform also leaves additional_tools input items
in place when the tools param is not a list, instead of raising while hoisting

* fix(fireworks): hoist additional_tools when tools is a tuple

litellm.responses passes a tuple tools argument through to the Fireworks
transform unchanged, so the non-list guard skipped hoisting and left the
additional_tools item in the input. Treat tuples like lists and cover both
shapes in the drop_params merge test

feat(model-hub): show each deployment's full prices in the model hub (#50145)
* feat(model-hub): show each deployment's full prices in the model hub

The model hub only showed one input and one output price per model, the highest across its
deployments. Each model group now lists every deployment's prices, read from the same entry
billing charges, including cached tokens, long-context tiers, flex, priority, batch and
tiered ranges. Both the logged-in and public hub detail views render them in one table per
deployment, labeled by provider only

* refactor(ui): move model hub pricing breakdown text onto i18n

Route every string the deployment pricing breakdown writes through t() under a new deploymentPricing group in en.json, plus the three hub headings that host it. The English on screen is unchanged

* fix(model-hub): show Vertex regional prices and explicit cached reads as billed

A Vertex deployment outside the global endpoint now shows its token prices with the regional
uplift billing applies at the deployment's location. The explicit cached read price shows per
1M tokens on its own row instead of a raw per-token value. The breakdown also says that
adjustments made per request, like off-peak discounts and regional or data residency
surcharges, aren't included

* fix(model-hub): show prices written as text the way billing reads them

A price written in config.yaml as 3e-7 arrives as text. Billing turns it into a number, but
the hub dropped it, so a deployment showed no price or the cost map's price instead of its own.
The hub now reads numeric text for regular prices and size-based price ranges, and skips text
that isn't a number

* style(ui): format public model hub test

* test(model-hub): name the deployment pricing fixture to stay within the inline object lint budget

feat(redis): serve the proxy's common Redis call with Rust stores (#50170)
* feat(redis): route the router, rate limiters and auth through the native store families

Format the rate limit store, sort its __all__ and give the routing read batch and two tests concrete list and dict types.

* fix(router): give the registry's default usage store a memory-only handle

RouterUsageStore now takes a handle, so the default passed None and any usage read before RustCore swapped in its store raised AttributeError.

* test(redis): build stores from native handles and wait for router tasks

Tests still used the pre-refactor store constructors (Store(None), handle= factories, NativeIncrement, tuple scopes). The router outcome tests counted 20 loop ticks, too few now that the allowed-fails increment resolves on the native runtime, so settle() waits for the scheduled tasks instead.

feat(proxy): give Codex accurate model entries for every model in /v1/models (#49825)
* feat(proxy): give Codex accurate model entries for every model in /v1/models

* fix(router): read a deployment's upstream model without a not-required key access

* fix(proxy): keep Codex tiers for unpriced deployments and match stock entries by declared provider

A deployment with no token price no longer votes a Codex service tier off,
an undescribed model keeps Codex's default reasoning summary parameter,
a Bedrock deployment naming its provider in custom_llm_provider gets Codex's
stock entry, and Bedrock provider namespaces follow the AWS model id format.

* fix(proxy): import cost tracking and provider helpers lazily in the Codex catalog

lite codex imports the catalog before the SDK is initialized, so importing
cost tracking, the Bedrock helpers or provider resolution at module level hit
a circular import and broke every lite command.

* fix(proxy): drop Codex's fast speed tier wherever its priority tier is dropped

Codex shows /fast for a leftover fast speed tier even when service_tiers
no longer offers priority, so an alias, an empty configured tier list or
a configured list without priority showed a /fast toggle that sends nothing.
One helper now sets service tiers, speed tiers and the default together.

* fix(proxy): give an older Codex a translated entry for models past its version

Codex's own entries name the oldest release that can read them in minimal_client_version. A release older than that can fail to decode the entry, such as a reasoning effort it has no name for, which fails the whole catalog, so it now gets the translated entry, whose levels are trimmed to that release

feat(router): add the Rust router core with the host as its only boundary (#49513)
Adds the litellm-router-core crate, its step-driven PyO3 bridge
(RouterCoreHandle / RouterCall) and RustCore (litellm/router_rust/),
served behind LITELLM_RUST through the ROUTER route rule. The host
call-out is the only boundary: every attempt goes through Host::invoke,
there is no native executor path, and RustCore never builds, wraps or
forwards to PythonCore, so router_python_core.py stays deletable.
Attempt preparation lives in litellm/router_attempt.py so it outlives
router_python_core.py.

RustCore matches PythonCore's behavior, including its known bugs (fixed
in follow-up PRs). Routing decisions (strategy picks, routing groups,
PTU, pre-routing, pre-call checks, fallback walk, health routing, access
groups, weights, cooldowns, allowed fails, usage) live in the crate;
work that needs live Python objects (request shaping, endpoints,
streaming, model info facts, callbacks, alerting, prompt management)
lives in the host-side litellm/router_rust/ package (steps/, invoke/,
surface/) driven by Rust steps.

The crate owns the registry. It runs the deployment build loop (secret
references, ids, organization fan-out, install order) and asks the host
for what needs Python, one deployment at a time so errors surface where
Python raised them: secrets, validate, provider and added steps. It
holds the model list, the index maps and the pattern routers with the
Python core's history rules (host_index.rs), and answers the registry
lookups (lookup.rs). The Python views of that state in
litellm/router_rust/surface/ (model_list, index(), names(), patterns())
read the handle, and every write to them becomes a changeset. Model
info, deployment model info, configured limits and model group info are
merged in the crate (model_info.rs, group_info.rs) from catalog rows and
facts the host answers on a model_info step asked at query time, so
price reloads and register_model stay visible. The usage cache key
format is defined once, in the crate.

The crate records each attempt's outcome itself rather than through
litellm callbacks. A streamed attempt is deferred: it counts its
request when the stream opens, and the host's stream wrappers report
the success with the final usage, or a failure after the first chunk,
when the stream ends, as the Python core's callbacks do.

tests/unit/test_router/core characterizes PythonCore's public behavior
and runs every test on both cores, with nothing pending; only the names
of the Python core's own outcome callbacks are asserted on Python alone.

litellm.Router is now final: subclassing it raises TypeError at the class statement, and the
machinery that kept subclass overrides working is gone. The Rust core never honoured subclass
overrides, so they would have silently stopped running there. Custom routing goes through
register_plugin(), settings through apply() and outcomes through observe(). This is a breaking
change for anyone subclassing Router.

Fuzz parity fixes on top of the rebase: the Rust core keeps num_retries,
max_fallbacks, allowed_fails, retry_after, timeout, the tag settings,
routing_strategy_args and the fallback lists as given (the crate reads
them as numbers, update_settings casts as Python does); a deprecated
`model_list = [...]` write reaches the Rust core; a failed set_model_list
is all or nothing on both cores (the deployments served before the call
are put back and the error raised); config_deployments() is a generator and `del` of a plain
attribute works on the Rust core. Least-busy pick reservations from
main now work on the Rust core: its selectors share one reservation
store, routed calls reserve and free their unstarted picks, and
select() and batch cancel do not reserve. On the Python core a dropped
upsert takes its name back off deployment_names, and
get_deployment_order reads every numeric spelling as one int so mixed
orders no longer raise TypeError.

Rulings on the remaining differences, the Python core changed where it
was the odd one out: sync picks and picks by deployment id apply the
team filter as async picks do, so another team's deployment is refused;
the fallback lists and default_litellm_params in RouterSettings are
copies, so an in-place edit is ignored and settings change only through
apply(); one health record with an unreadable timestamp drops out alone;
an empty fallback entry is skipped; a bool cooldown_time is refused at
construction, a bool or string cooldown_time on a deployment or a call
falls back to the router default, and a failure status that no HTTP
status can be is recorded as 500; an infinite or NaN cost and a whole
number wider than 64 bits (ptu_shares) are refused on both cores with
the same error (litellm/router_utils/deployment_numbers.py); and a
/v1/messages stream whose provider iterator raises cools the deployment
and retries like a non-stream call, with the Rust core waiting for that
cooldown before its retry picks.

Differences the proxy parity fuzz and its regression tests found on the
Rust core: a file upload or a batch on an uploaded file falls back only
within its own model group, as on the Python core, since the file lives
with one provider (the host sends same_group_fallbacks_only and the walk
skips targets in other groups); Decisions calls drop deployments whose
provider has no Decisions config, and deployments that refuse the audio
or videos a call carries, unless that would leave none, as the Python
core does, while the retry count still reads the whole group; a file
upload that fails on one order level is created on the next level's
deployments rather than the first level again; and a response that
cannot be converted (a text_completion body without a message) reports
only its own traceback, so a rate limit handled by the attempt before it
no longer turns the error into a 429, and both cores return 500.

fix(least-busy): reserve the picked deployment so a burst of requests spreads out (#47484)
* fix(least-busy): reserve the picked deployment so a burst of requests spreads out

The in-flight count only went up in log_pre_api_call, which runs after
selection and the pre-call hooks. Requests selected in that window all saw
the same counts and landed on the same deployment (16 simultaneous
requests over 4 deployments went as lopsided as 12/4/0/0 in the proxy).

When the router selects for a request it is about to send, least-busy now
records a reservation for the chosen deployment in the same synchronous
step that reads the reservations, and log_pre_api_call turns it into the
normal in-flight count. Selections without request kwargs (token counting,
probes) do not reserve. A reservation whose request never reaches the API
call expires after 30 s. The shared and per-worker counts and their
success/failure decrements are unchanged.

* fix(least-busy): prune expired and empty selection reservations

The reservation map kept a key per model group forever, so a wildcard
route with caller-chosen model names grew it without bound. Drop expired
and empty entries on every write.

Signed-off-by: Oliver Yu <tc3oliver@gmail.com>

* fix(least-busy): keep pick reservations in the shared router cache

Selectors that share a router cache dedupe to one registered callback, so
only that instance saw log_pre_api_call. Reservations held on the other
instances were never released and skewed picks for the full TTL. Storing
them in the router cache's in-memory layer lets any selector release them,
and the per-key TTL replaces the full-map rebuild on every write.

Tests now hold the burst with a barrier instead of a sleep and use a manual
clock object.

* fix(least-busy): restart the reservation TTL on every write

InMemoryCache keeps the TTL a live key was first given, so a reservation
key that kept being rewritten still expired 30 s after its first pick and
took the newer reservations with it. Drop the key before each write so the
TTL counts from the latest one, and leave it deleted once it is empty.

Signed-off-by: Oliver Yu <tc3oliver@gmail.com>

* fix(router): count least-busy decisions calls and release reservations on cache hits

Least-busy now reads the model group from litellm_metadata before metadata, so /v1/decisions calls that carry caller metadata are counted in flight and release their reservation at pre-call. A response cache hit releases its reservation instead of decrementing another request's in-flight count, and Responses WebSocket turn admission selects without reserving. The reservation store is reached through a typed protocol.

* fix(decisions): count proxy /v1/decisions calls in least-busy's in-flight totals

* fix(least-busy): keep reservations out of the shared router cache and count requests that start during a Redis read

Least-busy now reads a call's deployment from the routing metadata the router sets, so /v1/decisions logging params stay as on main and failed decisions calls no longer start cooldowns.

* style(router): wrap the least-busy reservation store line

* fix(least-busy): lock the reservation read-and-update so threaded sync calls keep each other's picks

Router.completion from a thread pool and sync success callbacks can read and rewrite a deployment's reservations at the same time, so one thread's pick or release could be lost.

* fix(least-busy): release a pick whose call ends before reaching the provider

A call that fails or returns before the provider handoff (a 400 for an unsupported param, token counting, a proxy-gate rejection without a start log, batch create) now drops its reservation instead of decrementing a count it never added. Router.select picks and batch cancel no longer reserve, since neither makes a call that logs.

* test(least-busy): give callback fixtures a fixed call-start time

The routing-group tests fed least-busy a finished call without the start time litellm stamps before counting it, so the count stayed up after the fix. Fixtures now use a fixed timestamp instead of the clock.

* fix(least-busy): free tier-group picks, stop lookups reserving, and count only started attempts

Reservations are keyed by deployment id, so a complexity, auto, adaptive or
quality router frees its tier pick when the call starts. Each started attempt
is recorded under its call id, and only a recorded start lowers the count when
the attempt ends, so a fallback hop rejected before the provider frees its pick.
Whether a pick reserves now comes from a context variable set by the routed
call sites, so get_available_deployment and the deprecated
async_get_available_deployment no longer hold a deployment, and custom routing
strategies and Router subclasses keep their method signatures.

* fix(least-busy): free a request's unstarted picks when it ends

Each pick now carries its call id, so a start frees only its own call's pick, and the router frees every pick a request never started once that request ends. A fallback hop rejected before the provider no longer leaves its pick reserved for 30 seconds.

* fix(router): free a least-busy pick when a vector store create ends

* fix(router): free least-busy picks of calls made without a call id

* fix(router): free the least-busy pick of a sync text completion

* test(router): use fixed start times in least-busy fixtures

* fix(router): free the least-busy pick of a sync generic call that fails before its provider

* fix(router): read in-flight counts and start attempts under one lock so a busy deployment never looks free

* fix(router): keep pass-through lookups from reserving least-busy picks

* test(least-busy): wait for the helper thread to start before the timed join

* fix(least-busy): keep realtime sessions out of in-flight counts

fix(azure)!: answer 401 when Entra rejects the deployment's credential (#49863)
* fix(azure): answer 401 when Entra rejects the deployment's credential

A ClientAuthenticationError from the Entra token provider (wrong, expired or rotated client secret) used to surface as a retryable 500 carrying the app's client id and Entra trace ids. Map it to a 401 AuthenticationError that keeps the AADSTS code and first sentence with GUIDs redacted, on both the direct token fetch and the provider handed to the OpenAI SDK client. Network failures stay 500.

* fix(azure): keep network failures to Entra a retryable 500

azure-identity wraps a transport failure in ClientAuthenticationError, so the
401 mapping now skips errors whose cause chain holds ServiceRequestError or
ServiceResponseError

* fix(azure): cover async token providers and Entra 5xx, and scope caller-sent Entra credentials

* fix(azure): map only AADSTS-coded Entra rejections to 401 and keep caller credential failures out of cooldown

An Entra ClientAuthenticationError now answers 401 only when its message carries an AADSTS code, its HTTP
status is not 429 or 5xx, and the code is not the AADSTS50196 throttle, so a chained credential's outage or
throttle stays a retryable error. Caller-sent Entra fields no longer change the deployment id; a 401 from a
value the caller sent skips the shared deployment's cooldown instead. The Azure AI Foundry agent token fetch
maps the same rejection, and the A2A endpoint answers it with HTTP 401.

* fix(router): count router default_litellm_params as configured Entra credentials when deciding cooldown

* fix(azure): keep transient Entra codes retryable and scope 401 handling to Entra rejections

ClientSecretCredential drops Entra's HTTP status, so throttling and transient
codes (AADSTS50033, 50196, 90006, 90024, 90033, 90055) now stay retryable
instead of mapping to 401.

The A2A endpoint answers 401 only for an AuthenticationError caused by an
Entra token rejection, and the router skips cooldown for a caller-sent Entra
field only on Azure-family deployments. The azure/ Decisions route and the
Bing grounding search tool now map an environment-credential rejection to the
same 401.

* fix(azure): map only known Entra credential rejections to 401 and cover the OIDC token exchange

Unlisted AADSTS codes keep the retryable 500, the router skips the 401 cooldown only when an Entra rejection caused it, and a federated token Entra rejects answers the same 401 on Azure chat, Responses and A2A agents

* fix(azure): answer 401 for Entra rejections on the /azure passthrough and token counting

The fallback hop skips cooldown when Entra rejected a credential the caller sent,
Prometheus counts a deployment's own Entra rejection as a deployment failure again,
and an OIDC exchange error keeps Entra's headers so Retry-After reaches the router.

* fix(azure): keep a no-op caller Entra field from skipping cooldown and redact the passthrough 401 message

A caller-sent Entra field now skips the deployment's cooldown only when it
differs from the deployment, its named credential, the router defaults, the
AZURE_* environment variables and the default scope. An empty value counts as
unset, so a deployment whose own secret is wrong still cools down when the
caller's field changes nothing about the token request.

The /azure passthrough's Entra 401 message goes through the same internal
hostname redaction as other client-facing errors.

* fix(router): compare a caller's Entra field with the value the deployment uses

A caller-sent Entra field skipped the cooldown only when it matched no
configured source, so a value equal to an environment default the deployment
overrides (a stale AZURE_CLIENT_SECRET, say) counted as the deployment's own
and let a caller's rejected credential cool down a working deployment.

The check now resolves the value the deployment would use without the caller,
in order from the router defaults, the deployment, its named credential, the
AZURE_* environment variables and the default scope, and skips the cooldown
only when the caller's value differs from it.

* fix(azure): follow the settings merge for empty Entra fields and keep non-rejection OIDC exchange errors unchanged

* fix(azure): count only the failed attempt's Entra rejection and ignore a non-callable token provider

fix(agentic)!: surface a failed agentic follow-up call instead of the pre-loop tool call (#49227)
* fix(agentic): surface a failed agentic follow-up call instead of the pre-loop tool call

* fix(agentic): surface failed follow-ups from the OpenAI chat dispatcher and update pinned integration tests

* fix(agentic): end a capped agentic turn on chat and responses instead of a retried 500

* fix(openai): run agentic hooks after the first call's error handling so a follow-up error keeps its own type and message

* fix(agentic loop): end capped turns on every chat path and bill the first call when a follow-up fails

A turn refused at max_agentic_loops now drops the internal tool calls of every hook that claims calls in it, while a call the client declared survives. The hosted_vllm and openai chat paths now carry the loop depth, fingerprints and max_agentic_loops into the follow-up, so they stop at the cap instead of looping forever.

A failed follow-up call now records the first call's usage and cost on the request's failure log before the error reaches the client. A code interpreter sandbox that is missing or fails becomes the tool call's output for the model to handle, so the turn completes without a retry.

On native streaming /v1/messages a hook or follow-up failure now reaches the client as an Anthropic error event with the mapped type, and compresr declares its retrieve tool so the stream holds it back. Comments and docstrings the branch added against the repo rule are removed

* fix(agentic loop): bill retried attempts and clean up what failed or capped turns return

The router's retry loop now carries each failed attempt's paid first call into the request's billing, so a request whose follow-up keeps failing bills every first call on its failure row, and one that recovers bills the failed attempt's first call on its success row. A failure row no longer adds unpriced estimated tokens on top of attempts that were billed, so its tokens match its spend

A sandbox failure now answers the model with a fixed sentence and marks the code_interpreter_call as failed, without the sandbox's error text. Code interpreter on /v1/responses with Claude now runs its loop, because the bridged inner call no longer strips the hook's own markers

Dropped internal tool calls leave the kept calls numbered from 0, also on a replayed stream. A capped native /v1/messages stream now says the loop hit its limit and that max_agentic_loops raises it, instead of asking the client to retry

The agentic refusal and hook error logs no longer include the model or the exception text, and the agentic loop helpers take typed messages, params, and read-only fingerprints

* fix(agentic loop): keep a recovered retry's cost breakdown on the response it returns

A retried agentic request that recovers no longer adds the failed attempt's first call to its success row. The proxy keeps the follow-up's own row for that request id, so the added spend never showed up in the stored row, and that duplicate row is tracked separately. When every attempt fails, the failure row still bills each attempt's first call

Pricing a first call for the failure row no longer replaces the request's cost breakdown. Before, a recovered retry answered with x-litellm-response-cost-original, -input, and -output from the failed attempt's first call. Now its headers and logged breakdown match a request that succeeds on its first try

* fix(agentic): stop retrying a request whose agentic follow-up failed and bill every round it served

An error raised by an agentic follow-up after the first call was served now carries a typed mark, so the
router's retry loops, the mid-stream retry, and litellm's num_retries wrapper raise it as is instead of
rerunning the whole request. A failure of the first call itself still retries, and fallbacks still run.

The failure row bills every round the loop served before the failure, at any depth, and a later attempt
that succeeds bills what the failed attempts paid on its success row, with the cost breakdown and the
response cost headers adding up. The error response's x-litellm-response-cost reports the same amount
its failure row bills. Failure rows outside agentic hooks keep the prompt-token estimate they had before.

A refused tool call now matches by id among the refused ids, or by name among refused calls that carry
no id, so a name-only refusal next to an id refusal is no longer kept.

* fix(code_interpreter): delete a session sandbox whose code run failed so the next call starts a fresh one

* fix(code_interpreter): delete only the session sandbox that failed, never its replacement

* test(code_interpreter): type the session sandbox test helpers

* fix(proxy): report what a failed agentic follow-up's failure row bills on /v1/messages errors

* fix(agentic): keep the no-retry mark through error mapping and bill only failed follow-ups on success

An agentic loop error that is not a provider error, such as the streaming chat cap or a crash in a hook's
plan build, now keeps its no-retry mark when litellm maps it to an APIConnectionError, so the router no
longer reruns every paid round. The mark is stored on the exception, so a built-in error can carry it too.

A crash in a hook's plan build on /v1/messages and /v1/responses bills the first call on its failure row.

A recovered attempt adds a failed attempt's usage to its success row only when that attempt was a failed
agentic follow-up. Other failed attempts, such as a dropped stream, log their own row as on main.

A code interpreter sandbox that fails while running the code now says the code may have run but its
result is lost, instead of saying the code did not run.

* test(responses): bill a retried MCP request each attempt on its own row again

Round 4 stopped adding a non-agentic failed attempt to the success row, so this test goes back to main's assertions: the success row bills only its own rounds and the failed attempt's first round stays on its own failure row

* fix(spend): name a failed follow-up attempt the success record already bills

With the usage meter on, a failed agentic follow-up attempt gets its own charge-eligible record, and the request's success record also carries that attempt's usage and cost once the success row bills it. The success record now lists the attempt's record ids in included_attempt_ids, so a reader can tell the success record already covers it. Nothing changes when the meter is off

* fix(spend): count a billed failed follow-up's tokens on the success row

* fix(spend): bill a failed follow-up on a fallback served from cache

* fix(spend): show a billed failed follow-up in a cached fallback's cost breakdown

* fix(spend): keep a failed follow-up's billing state off the request-merged call details

* fix(spend): record the cost breakdown of a successful agentic follow-up

The chat agentic loop returned the follow-up response with the cost its own internal call had already stamped, so the request's logging reused that cost and never recorded cost_breakdown on the spend row. The loop now drops that stamped cost unless the follow-up was served from the cache, and the request prices the response itself

fix(rate-limit): estimate embedding image and audio data URIs as media in TPM pre-call checks (#49831)
* fix(rate-limit): estimate embedding image and audio data URIs as media in TPM pre-call checks

* fix(rate-limit): count embedding media as media only on models that embed it

A data URI sent to a text-only embedding model is read as text, so it keeps
the text estimate there. On models flagged supports_embedding_image_input,
image and audio use the chat media estimates and PDF and video count at most
the model's max_input_tokens. The same estimate now feeds project and key
limits, the usage-based, latency and cost routers' deployment tpm, and the
deployment itpm check.

* fix(proxy): count embedding media only where the backend reads it as media

Vertex AI, Gemini, Azure AI and Bedrock count a strict base64 data URI as
media per item. Cohere counts it as media only when the whole batch is
media, and Voyage, OCI and unknown models keep the text estimate. File
blocks carrying a data URI count like the bare URI.

The router context window pre-call check and the batch limiter now use the
same estimate, resolving each deployment or JSONL row model to its
backends. The cost map gains supports_embedding_image_input on
voyage/voyage-multimodal-3 and oci/cohere.embed-multilingual-image-v3.0.

* fix(router): hold each embedding media item to the context window on its own

A PDF or video data URI alone already reserves at most the model's
max_input_tokens, but the context window pre-call check then ran the
blanked input through the Responses transform and added a few framing
tokens, so a PDF that Vertex accepts got a 400. When every input item is
media, the check now returns the largest item's media estimate, since an
embedding request embeds each item separately

* fix(proxy): leave embedding media out of the context check and narrow Bedrock media scope

The router context window check now counts only the text of an embedding input, so Titan image lists no longer 400. Bedrock Marengo and Nova with a PDF keep the text estimate since they read those inputs as text or reject them, async_invoke Nova counts images as media, and the unused batch limiter change is dropped.

* fix(bedrock): bill Cohere embeddings by Bedrock's input token count header

* fix(embeddings): check data URI base64 in place and keep Bedrock Cohere text usage

The strict base64 check now scans the payload in place instead of decoding
and re-encoding a full copy. Bedrock's billed token header is used only for
image requests, so text-only Bedrock Cohere usage matches main. The deployment
itpm estimator change is reverted, since the router never passes embedding
input to that check.

fix(bedrock)!: fail a Nova Sonic realtime session whose Bedrock stream drops instead of closing 1000 (#49170)
* fix(bedrock): fail a Nova Sonic realtime session whose Bedrock stream drops instead of closing 1000

The Bedrock SDK ends the output stream the same way for a dropped connection as for a session that sent sessionEnd, so the handler treated a dropped stream as a clean finish. The client got a 1000 close with no error event and the router logged 200 OK with no retry

An output end now counts as clean only after the client left and the handler began closing the Bedrock input. An earlier end raises a 503 BedrockError, so the client gets an error event and a 1011 close, the failure handlers run, partial spend is still logged, and a retry of a committed session is still refused

* fix(bedrock): fail a dropped Nova Sonic session right away and log it as failed

When Bedrock's output side ends mid-session, by a drop or a modeled stream error, the client side no longer spends the close timeout sending close messages into the dead input stream, so the error reaches the app right after the drop. A session the app ends itself still sends Bedrock its close messages and closes the input

The replay refusal now leads with the committed cause, so the error event and the cut 1011 close reason both start with it. It stays a 400 and is tagged as a failure outside the selected deployment, so router retries and fallbacks of a dropped session no longer add extra failure counts

A clean realtime session now counts once toward its deployment's cooldown success counter, so cooldown reads the real failure rate instead of 100 percent. Realtime tpm and rpm counting is unchanged

The spend row of a session the provider ended now reads failure with its error information, while the events already forwarded are still billed. A session the app ended keeps logging success

* fix(bedrock): agree on a dropped realtime session's failure across loggers and the spend row

A realtime session's success event now reports status failure, with the same
error_information the spend row stores, when the session recorded a provider
failure in its metadata. Usage already streamed stays billed and the router
still counts one cooldown failure

The spend row builder now runs every row's error_information through
sanitize_error_information_for_spend_logs (DB size cap plus prompt redaction),
so the realtime failure rows get the same treatment as the proxy failure hook,
which no longer sanitizes on its own to avoid truncating twice

Drop the selection-failure tag on the committed-session refusal, since the
shared logging object already keeps a retried refusal out of cooldown, and pin
the router's realtime success counting with an OpenAI realtime deployment

* fix(bedrock): count realtime router successes only for sessions that logged one, and log first-turn drops

The router counts a realtime success only when the session's success handlers ran, so a refused handshake or an upstream close before any frame no longer offsets its failure. The success event's payload status stays success again, so each logger gets one failure record per dropped session, while the spend row still reads failure from the metadata the Bedrock handler records. A committed Bedrock session that fails before any logged event now gets one zero-cost Logs row. After an output failure the input stream is closed in the background, so the SDK body writer finishes without delaying the client's error. Every input send failure reports the same 503 stream-ended cause as an output drop

* fix(realtime): count a router success only for a session that ended cleanly

A realtime session the upstream closes with 1011 or 1006 after its first frame now marks itself as ended abnormally where that close is seen, in the shared relay and in the OpenAI Live handler, so the router no longer counts it as a cooldown success. The success callbacks still run, so the proxy keeps the budget and parallel-slot settlement it had

A Bedrock session that fails before Bedrock sends any usage now logs no success event, as on base. The spend-row failure fields go into a new metadata mapping instead of the request's own dict, validated with a pydantic TypeAdapter instead of an unchecked TypeIs guard. The handler tests drop a wall-clock bound and type their helpers

* fix(bedrock): log a dropped realtime session's usage from its own logging state

The failure event replaced the shared standard_logging_object while the
queued success dispatch was still running its callbacks, so loggers
received $0 and 0 tokens for a billed dropped session.

* fix(proxy): settle a rate-limit reservation once when a request logs a failure and a success

A dropped realtime session fires a failure event and then a success event for the same call. The v3 limiter refunded the TPM reservation on the failure and released it again on the success, so the key's TPM counter went negative. The success path now skips a reservation the failure already released and marks it settled for a later failure. The realtime handler test callbacks are typed

* fix(rate-limit): settle each token reservation once when a request logs both a failure and a success

A dropped realtime session logs a success for its usage and then a failure. After a success the
limiter now clears every reserved amount (TPM, PTU, ITPM, OTPM), so a later failure refunds nothing
twice. A new reservation written in the same context after a released one now starts clean, so
reserve, fail, reserve, succeed charges the second request's usage once instead of 78 TPM or
28 ITPM for 27 and 20 used

* fix(rate-limit): take a token hold before awaiting so concurrent success and failure callbacks settle it once

* fix(rate-limit): track the ITPM/OTPM hold's release apart from TPM so a nested pre-call keeps the request's project IO charge

* test(rate-limit): pin the split hold-release flags across nested MCP pre-calls

* fix(realtime): count a relay that fails on its own as an abnormal end

* test(realtime): pin the relay failure exit with a client frame the provider rejects

feat(model_info): add supports_continuation capability flag for Gemini long decode continuation (#49500)
* feat(model_info): add supports_continuation capability flag for Gemini long decode continuation

* fix(router): keep a deployment's supports_continuation override on that deployment

A supports_continuation value set in one deployment's model_info was written onto the shared provider/model cost map key, so every other deployment of that model reported it too. List it with the other per-deployment capability flags, and cite Google's long decode page next to the cost map assertion

* fix(cost-map): flag vertex_ai/gemini-4-argon-cyber-permissive with supports_continuation

Google's Vertex Gemini 4 Argon guide gives gemini-4-argon-cyber-permissive the same long decode limit as gemini-4-argon, and LiteLLM already continues its long requests, so the cost map now says so in both copies.

* fix(router): count only a boolean true supports_continuation when building a model group

fix(responses): serialize sequence_number on every bridged streaming event (#44944)
* fix(responses): serialize sequence_number on every bridged streaming event

* test(responses): cover sequence_number on bridged streaming events

* fix(responses): read undeclared fields through dict accessors and number guardrail block continuations

* fix(responses): scope dict reads that see undeclared fields to Responses stream events

Moves the extras-aware __getitem__, get, __contains__ and items from the
shared response base onto a new base for the 37 stream event classes, so
usage, Gemini, Interactions and moderation objects keep reading __dict__
and Gemini responses keep _hidden_params out of .get

* fix(router): renumber Responses stream events only after a fallback takes over

A stream that never falls back now keeps its provider's own sequence numbers, repeats included, so a starting_after resume still matches them. After a fallback the wrapper continues above the highest number the client saw

* fix(guardrails): keep Responses stream numbers unique when LLM Shield flushes held text

The restorer's flush copied the last delta and kept its sequence_number, so a
native stream repeated a number and a bridged stream sent the flush unnumbered.
A flush now takes the done event's slot and later events move up by one, and a
stream the provider never closed numbers its flush after the last event.

Also pins the created_at in the streaming iterator test fixture instead of
reading the clock.
