The prompt-management factory picks its deployment with a placeholder message. That
was inert while the pick ran on the synchronous path, which never runs the routing
plugin pipeline. Now that the pick runs the pipeline, a plugin classifying request
content would score the placeholder instead of the conversation, and the narrowing
it writes decides which deployments the real call may use.
Two routers in one process shared a single handler, because the callback
manager dedupes on the class name plus the handler's public attributes and the
handler had none. The second router's requests were never counted. The handler
now carries the id of the cache it was built on, so routers with different
caches both register while the two selectors one router builds for its routing
groups still collapse into one.
Clamping a negative count back to zero used SET, which drops the key's TTL, so
the next write started the hour over. It uses INCRBY by the negative amount now,
which leaves the expiry alone.
The Lua script had no test that ran it, so tests/local_testing covers both the
sync and async paths against a real Redis, and the file is wired into the
CircleCI job that provides one.
A Redis outage read as "every deployment is idle", because batch_get_cache
swallows the failure and answers with an empty dict. batch_get_counts and its
async twin raise instead, so a worker that cannot reach Redis falls back to its
own numbers rather than routing on zeros.
The counter's TTL is now set only on a key that has none, so a +1 left behind by
a worker that died mid-request ages out an hour after the key was created. It
used to be refreshed on every touch, which kept that stuck count alive for as
long as the group took traffic.
Two least-busy groups counted the same request twice, since the pre-call list
kept a selector per group while the success list deduped by class. The selector
now goes on through add_litellm_input_callback, which dedupes the same way.
A prompt-management model picked its deployment on the synchronous path, so the
new Redis read landed on the event loop and configured routing plugins never
ran. It awaits the async selector now.
A fake-streamed provider hands the adapter one chunk carrying both the
delta payload and the finish_reason, which is exactly what the combined
chunk splitter exists for, but its content check never listed the refusal.
The translation short-circuits on finish_reason, so that refusal text was
dropped and the client got `stop_reason: refusal` over an empty content
array, the symptom this PR set out to fix.
Both refusal accumulators also drop their `mutable-ok` lists for a plain
string attribute
The first-delta guard read `delta.refusal` directly, while the translation
three lines later goes through `openai_chat_refusal_text`, which also reads
the `provider_specific_fields` LiteLLM parks unrecognized fields in. A
provider that sends the refusal that way had its only refusal delta skipped
as blank, so the client got `stop_reason: refusal` over an empty content
array, which is the symptom this PR set out to fix
`vertex_ai/lyria-3-clip-preview` and `vertex_ai/lyria-3-pro-preview` were
registered with `supports_vision`, `supports_image_input`, and an `image`
modality, which contradicts their `gemini/lyria-3-*` siblings and makes
/model/info advertise image input on text-to-music models.
The new Lyria passthrough branch runs before the image-generation branch
and keys on the same `predictions[0].bytesBase64Encoded` shape imagen
returns, so only the cost-map lookup separates them. Cover an imagen
predict response end to end so a future change that drops that lookup
fails here instead of misbilling images as audio.
A decrement whose matching increment is gone, because the counter key
expired while the request was still in flight, used to recreate the key
at -1, and a deployment with a negative count looks permanently idle, so
it collects every pick from then on. The repair write that followed the
decrement could also land after another pod's increment and erase it.
The increment, the clamp at zero and the TTL refresh now run as a single
Lua call, so nothing can interleave between them.
Google prices Lyria per generated clip, so every Vertex Lyria entry in the
price map now carries a single output_cost_per_image and both the speech
and the passthrough cost paths read that one field. The old
output_cost_per_second and audio_seconds_per_prediction pair assumed a
30 second clip, which does not match the 32.768 second WAV Vertex returns,
and no other model in the map priced audio that way
Drops max_audio_length_hours and max_audio_per_prompt from the price map,
its schema, the generator, and ModelInfo, since nothing reads them, and
drops the audio_mime_type hidden param for the same reason: the response
already carries the resolved content type on its own header
Folds the per-model bundled catalog lookups into one cached parse of the
local cost map, validated with a TypeAdapter over a ReadOnly TypedDict
Keep each worker's own in-flight counter up to date alongside the shared one,
so a Redis outage routes on that worker's counts the way it did before this
branch instead of treating every deployment as idle.
Floor a counter at zero when a decrement finds the key gone, which happens when
a request outlives the 1 hour TTL, so an expired counter cannot settle at -1 and
win every pick.
The selector picked up two suites that can never pass in this stack, so
editing either one turned the check permanently red: the presidio masking
suite calls pytest.fail without an analyzer and anonymizer that up.sh
never starts, and the pipecat audio suite skips itself at import time
unless the NLTK punkt_tab data is present, which nothing installs.
tests/e2e/coverage_registry/test_collector.py had the same problem for a
different reason. Its nested pytest.main autoloads pytest-retry from the
ci group the workflow installs and dies with "INTERNALERROR: no option
named 'filtered_exceptions'", so the collect-only pass now disables that
plugin. The plugin's entry point is pytest-retry, not retry, so the same
one-word fix lands on mutmut's pytest_add_cli_args, where "-p no:retry"
was disabling nothing.
Two smaller holes in the harness: a canary argument the shell never
expanded used to select nothing and let the gate pass green, and a secret
that cannot be represented in both bash and dotenv was rejected without
naming the key.
Both bridges opened an empty text block on a refused streaming turn and
closed it without a single delta, so a client replaying that assistant
turn got HTTP 400 "text content blocks must be non-empty" from Anthropic.
The safeguard-refusal fallback that motivated withholding the text only
runs on the awaited non-streaming response, so nothing needed it withheld
Move the refusal readers into the shared messages/utils helpers so the
adapters stop reaching into each other's private statics, which is also
what put reportPrivateUsage over its budget
Least-busy kept one dict of in-flight counts per model group in the
router cache, which reads in-memory first, so every worker and replica
routed on its own stale copy and each write overwrote the shared value.
Counts now live in one key per deployment, incremented and read through
Redis when the router has a Redis cache, and in the process-local cache
otherwise.
The first canary run failed pass 1 because the stage-mirror config had no
openai-text-embedding-3-small while test_llm_api_routes_group_grants_every_llm_endpoint
calls /embeddings with it; the public log named the test, which is the
behavior the previous commit added
A harness-only change (proxy_client.py, conftest.py, pytest.ini, the gateway
config, .github/e2e-stack, or the workflow) selected nothing, so the stack was
never exercised by the change that touched it. select_tests.py keeps the
changed-file rule and adds the access_control suite whenever a harness file
changes. The run step now reports the pytest exit code before the evidence
check, prints pytest's summary line per pass so the rerun count is visible,
and assert_tests_ran.py names each failed or errored test as classname::name
The MongoDB Atlas vector store provider imports pymongo lazily from the
opt-in `mongodb` extra, but none of the shipped images installed that
extra. Any image-based deployment that configured a MongoDB vector store
failed at search time with "requires the 'pymongo' package", which the
user cannot fix without extending the image
Adds `--extra mongodb` to every uv sync in the root Dockerfile,
Dockerfile.database, Dockerfile.non_root, and the gateway component
image. The backend component does not serve /vector_stores so it is left
as is. The extra resolves from the existing uv.lock to pymongo 4.17.0
plus dnspython 2.8.0, no lock change needed
(cherry picked from commit 16fd14f537)
The retrieve tool was injected whenever any hash=<24hex> string appeared in the
restored conversation, including protected rows and caller-authored text, so a
git SHA in a tool result registered a bogus hash and billed a useless retrieval
round trip on every later turn. The compression service reports the hashes it
actually stored in ccr_hashes; that field is now the only source, validated to
the service's own 12 to 24 hex grammar before it reaches the retrieve URL.
Assistant rows are no longer flattened to strings before compression: the
service protects assistant text blocks but has no gate for assistant strings,
so the model's own earlier tables came back as a schema line plus CSV.
Adds ccr_retrieval (default true) so operators on a marker-free sidecar can
turn the retrieval loop off entirely.
The chat and Responses bridges serialize tool_use blocks with model_dump(), so every
bridged /v1/messages response carried LiteLLM's internal provider_specific_fields key
(null, or a Gemini thought signature). Clients replay the block verbatim, and the next
turn that lands on a native Anthropic deployment (auto-router tier change, model swap)
is rejected with "tool_use.provider_specific_fields: Extra inputs are not permitted"
Strip the key from replayed content blocks at the single native Anthropic dispatch so
already-poisoned transcripts self-heal on every native provider, and stop emitting the
null on new responses. The bridges keep reading the signature for the Gemini round trip
Closes#19739
The API Keys route mounted the pre-App-Router UserDashboard component,
whose beforeunload handler cleared sessionStorage on every refresh of
the Virtual Keys page. That wiped the Playground chat history and model,
the logs live-tail preference, and everything else other pages keep in
session storage. The same component also re-decoded the login token,
re-fetched teams, and wrote cache entries nothing read.
ApiKeysDashboard now renders VirtualKeysTable and the Create Key button
directly, taking identity and role from useAuthorized like every other
page. Create Key is hidden for view-only roles, which the proxy already
rejects on /key/generate. The legacy component, its test, the fetch_teams
helper, and their grandfathered eslint suppressions are removed, and the
ProxySettings type moves to useProxySettings.
* fix(guardrails): don't inspect embeddings in the AIM and Cato hooks
`pre_call_hook` fires for /embeddings as well as chat. An embeddings body
carries `input` — documents being indexed, not a prompt — which
`build_inspection_messages` lifts into synthetic chat messages, so both hooks
inspect it as a conversation and a policy verdict on that text breaks a request
that was never one:
- AIM, anonymize + batched `input`: `has_non_string_content` is true for any
list, so `_anonymize_request` raises 400 "...multimodal input...".
- AIM, anonymize + single-string `input`: no error — the input is rewritten to
redacted text and the caller embeds text it never sent.
- AIM and Cato, block: the embeddings request is blocked outright.
Gate both hooks on a new `NON_CONVERSATIONAL_CALL_TYPES` deny-list. This is
deliberately not `TEXT_CONTENT_CALL_TYPES`: that allow-list omits
`anthropic_messages`, `responses` and `call_mcp_tool`, so gating on it would
stop these guardrails inspecting real chat traffic. An unrecognised or newly
added call type is still inspected.
* feat(guardrails): add inspect_embeddings toggle for AIM and Cato
* fix(guardrails): redact batched embedding input on anonymize
A list of plain strings is the /embeddings batch shape. AIM rejected it as
multimodal and Cato forwarded the original strings, so anonymize never
reached the provider for batched input. Redactions are now written back
element-wise, one redacted message per non-empty element, so a fully
redacted element cannot shift the following documents into the wrong slot.
* fix(guardrails): reject partial embedding redactions
* fix(guardrails): avoid unnecessary batch type check
* style(tests): drop trailing blank line in cato guardrail tests
* fix(guardrails): reject malformed batch redactions
* fix(guardrails): reject malformed batch redactions
* fix(guardrails): reject aim redactions with no text content
The anonymize path read role and content off every entry of the vendor's
redacted_chat before the shared write-back helper could refuse the payload,
so a message missing content, or a bare string in place of a message, raised
out of the hook as a 500. Validate the vendor list first and return the 400
the guardrail already uses for an unusable redaction.
* fix(guardrails): validate all aim redaction paths
Validate AIM redaction containers before request or output rewrites, reject
cardinality mismatches and empty output, and cover malformed vendor payloads
with regression tests.
* fix(guardrails): preserve aim output redaction alignment
AIM returns the inspected request messages followed by the assistant output.
Validate that full response and select the final redacted message instead of
requiring a single entry.
* test(guardrails): cover aim output anonymize alignment and malformed redactions

* fix(azure_sentinel): split batches under the 1MB ingestion cap and keep undelivered records queued
Azure Monitor rejects any Logs Ingestion body over 1MB with a 413. The Sentinel logger
posted the whole queue as one body and cleared it in a finally block, so an oversize
batch, a transient 5xx, or a failed token call dropped every queued record, and records
logged while a send was in flight were cleared with it. Both the standard and the audit
queue share the sender.
Move Datadog's proactive size split and 413 halving into a shared helper,
litellm/integrations/batch_utils.send_batch_with_413_split, and route Sentinel through it
with a 1MB size check. A lone record that still 413s is dropped, everything a transient
failure leaves undelivered goes back to the front of its queue, and the retry queue is
capped at max_queue_size so an unreachable workspace cannot grow memory without bound
* fix(azure_sentinel): retry undelivered records on the flush timer only
Requeued records made every later event cross the batch_size threshold, so a
down ingestion endpoint got one full-queue resend per request. Threshold sends
now go through flush_queue, so they take the flush lock instead of racing the
timer, and they stand down while records are awaiting retry.
A record that cannot be serialized raised out of the size probe and killed the
periodic flush task. The probe now runs inside the failure handling, so the
batch is split and only the record that cannot be serialized is dropped.
* fix(azure_sentinel): decide threshold sends under the flush lock
Concurrent callbacks all read logs_awaiting_retry before the first send
finished, so each one resent the whole queue once that send failed. The
flag and the batch_size threshold are now rechecked while holding the
flush lock, and each queue sends only itself instead of going through
flush_queue, which was retrying the other queue too.
* test(azure_sentinel): cover successful threshold waiters
* fix(azure_sentinel): preserve cancelled batches for retry
* fix(azure_sentinel): requeue only the undelivered part of a cancelled split
A batch over the ingestion cap goes out in pieces, so a cancellation partway
through requeued pieces the destination had already accepted and sent them a
second time on the next flush
The split helper now raises a cancellation carrying the records it never
delivered, and Azure Sentinel requeues those instead of the whole batch
* fix(azure_sentinel): drop batches a permanent rejection will never accept
A non-413 4xx from the ingestion endpoint or from the OAuth token call means the request
will fail the same way on every retry, so requeueing it held the batch, and every record
logged behind it, until the queue cap dropped them. Retryable statuses (5xx, 408, 429)
still keep the whole batch, and a shared classifier gives Datadog the same rule
The serialization probe now catches any exception, not just TypeError and ValueError,
because safe_dumps hands pydantic models to model_dump and can raise anything. It also
splits on record count, so a recovery flush sends batch_size records per request instead
of serializing the whole requeued queue to measure it
Both integrations re-raise a cancelled send as exactly asyncio.CancelledError. Python
3.12's asyncio.wait_for only translates the exact class into TimeoutError, so the
BatchSendCancelled subclass escaped the logging worker as an unhandled error
The awaiting-retry flag now follows the queue that survived the max_queue_size trim, so
a deployment with the cap at zero is not left waiting for a timer flush with nothing
queued to retry
* chore(logging): document mutable queue ownership
Annotate the queue detach and requeue constructions required by the logger's appendable queue contract so the type-discipline budget stays clean
* fix(datadog): preserve non-413 retry behavior
Keep Datadog's existing contract of requeuing every non-413 HTTP failure while Azure Sentinel applies its permanent-client-error policy through the shared splitter
* fix(batch_utils): requeue by default and let Sentinel opt into dropping
The shared splitter's default non-success handler is now requeue_after_http_error, the behavior Datadog had before the extraction, so a caller that omits the argument keeps its records. Azure Sentinel passes undelivered_after_http_error explicitly to drop permanent 4xx rejections
Also drops an explicit return None the strict ruff gate flags in the test helper
Format the model-picked id with %r so control characters in it cannot
break the log line. The regression test for the unlisted id keeps to
generic scoping wording
The sidebar and header were still keyed on legacy ?page= ids and mapped
back and forth through MIGRATED_PAGES, legacyPageHref and
legacyKeyForPathname. Leaves are now plain Next links to their path
route, the active item and breadcrumb come from usePathname, and the
setPage/defaultSelectedKey prop chain is gone.
The id-to-route table moves next to the dashboard root page as its only
consumer. That redirect now forwards the remaining query params instead
of dropping them, so deep links such as the proxy's MCP env-var setup
link (?page=mcp-servers&fill_env_vars=) no longer rely on the target page
reading the pre-redirect URL during its first render. The proxy builds
that link as /ui/mcp-servers?fill_env_vars= directly, and the Playground
warnings link to the real routes instead of relative ?page= URLs.
migratedHref is renamed uiHref, the /ui base-path helper it always was.
A one-character value in the provider secret bundle was masked too, which
turned every 1 in the run log into ***, including the pass numbers and the
gateway addresses, so the only public diagnostics were unreadable
