test(caching): assert sync cache-hit logging without depending on thread order (#47093)
Sync success callbacks run on a thread pool, so the miss and the two
hits can reach the logger in any order. Compare counts instead of the
list order.

fix(otel): report cache hits at zero cost with a cache-hit flag in V1 and V2 spans (#43604)
* fix(litellm): report zero cost and cache-hit attrs on cache-served spans

* fix(litellm): stamp cache-hit marker on HiddenParams carriers and restore probe side effects

gauntlet-mini on ace57d25f verified two live gaps. TextCompletionResponse and
ResponsesAPIResponse carry _hidden_params as a HiddenParams object, so the
dict-gated marker write skipped them and the served hit still stamped the full
price. The marker write is now container-agnostic, which it already was for the
partial-embedding stamp, and a regression test exercises the carrier end to end.
_uncached_response_cost also restores billed_token_rates, zero_cost_warned, and
the response_cost_failure_debug_information key alongside cost_breakdown, so the
probe leaves no pricing state on the call it reads.

* test(caching): cover cache-hit marker on HiddenParams carriers through the caching handler

* fix(logging): keep the uncached price probe's restores to the state it can leak

* fix(otel): emit V2 LLM-call span for cache hits with explicit cache attributes

* fix(otel): read cache payload fields defensively without casts

* chore(otel): clarify pyright suppression reason on cache payload reads

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

* fix(otel): build the cache-hit view from typing_extensions.TypedDict so import works on Python 3.10 and 3.11

* fix(otel): report cache hits at zero cost everywhere and mark misses

Cache hits now carry a zero cost breakdown and a zero hidden response cost,
the /v1/messages hit cost header follows chat and responses hits, every span
carries litellm.cache_hit, V2 hit spans drop server.address, an async hit keeps
the provider-prefixed model name, and the V2 attribute budget counts preset keys

* fix(otel): send a 0 cost header on cache hits and keep hits out of deployment TPM

Cache hits now send x-litellm-response-cost: 0.0 on chat, responses and
/v1/messages, while a fresh call whose cost is 0 still sends no header.

The async hit path stamps the same model name as main again. Stamping the
provider-prefixed name made a hit's tokens count toward the deployment's
TPM limit, so repeated cached requests hit 429s under usage-based routing.

Drop comments that restated fields and annotate new test values as Final.

* fix(otel): keep the served pricing basis on a cache hit's cost breakdown

A hit's breakdown now keeps service_tier, data_residency, vertex_location, and the discount and margin rates the served call recorded, with every amount at 0, so savings reports still read the basis. The hit header test now drives the live non-streaming header path.

* fix(otel): send zero breakdown headers on a cache hit and give hit spans a fresh call's cost keys

A hit's x-litellm-response-cost-original, -input, and -output headers now read 0.0 instead of going missing or carrying the full price. A hit's cost breakdown now comes from pricing the response as fresh, so every route exports the same keys, pricing basis, and rates with every amount at 0.

* test(integration): assert zero cost and the cache-hit flag on cache-served OTel V1 and V2 spans

* test: wait for the cache entry before the cache-hit request and build cost headers without a route_request double

* test: annotate the new cache-hit unit test locals with Final

fix(logging): keep the async request's logging payload when the sync success thread runs late (#47019)
* fix(logging): keep the async request's logging payload when sync callbacks run late

Treat the "cache" success callback as internal when deciding whether to start
the sync success thread for async requests. It has no branch in the sync
handler, so with `cache: true` that thread did nothing except rebuild and
overwrite model_call_details["standard_logging_object"].

When the sync handler does run for an async request (a real sync-only logger
is configured), it now builds its own payload and hands it only to its own
callbacks. The async handler keeps sole ownership of the shared payload, so
edits made by async logging hooks (for example the v3 rate limiter's mirrored
x-ratelimit headers that Prometheus reads) are no longer discarded. Sync
requests keep their existing behavior.

* fix(logging): keep sync cache hits logged and isolate the async-request payload build

The sync completion cache-hit path reused handle_sync_success_callbacks_for_async_calls,
so treating "cache" as internal silently dropped sync callbacks on sync cache hits. It now
submits the sync handler through its own method, as it effectively always did.

For async requests the sync handler builds its payload from a copy of the call details, so
message redaction cannot rewrite the shared standard_logging_object, and when it builds no
payload its callbacks keep the shared one instead of getting None.

* test(caching): lock sync cache-hit logging for completion, embedding and text_completion

* test(logging): keep sync hook edits off a caller-supplied payload for async requests

* fix(logging): give sync hooks a copy of the async payload when the thread builds none

* test(logging): check every legacy sync logger gets the thread's own payload

* test(logging): cover traceloop and supabase sync logging for async requests

fix(responses): log and bill every round of non-stream MCP auto-execute (#43667)
* fix(responses): log and bill every round of non-stream MCP auto-execute

Both model rounds run as internal sub-calls on the request's logging object, and the outer call logs the response the client received with usage, cost, and cost breakdown summed across the rounds. The internal-call gate now also covers the sync success callbacks, so an inner round no longer takes their first-wins slot

* fix(caching): let the parent call log and bill an internal sub-call's cache hit

A round of non-stream MCP auto-execute that the response cache served fired the
cache-hit callbacks on the shared logging object, so the spend log kept round 1's
function_call row and dropped the billed row for the answer. Internal sub-call cache
hits now fire no callbacks and carry a zero cost, and the summed cost breakdown leaves
out rounds served from the cache

* fix(logging): keep a parent row unique when its response came from the response cache

A RAG query or an MCP turn whose final round is served from the cache hands back the cached response's id, which already belongs to the row that cached it, so SpendLogs dropped the new row as a duplicate. Such a row now gets the cache-hit id suffix, and it is logged as a cache hit when it cost nothing.

* fix(logging): skip the zero-cost warning for a response served from the cache at no charge

A non-stream MCP auto-execute request whose rounds the response cache served is priced
at $0 before the parent marks it a cache hit, so it logged a false 'priced at $0'
warning and counted in litellm_zero_cost_requests_total. The diagnostic now treats a
response the cache served at no charge the same as a marked cache hit

* fix(responses): bill the paid first MCP round when a later step of the request fails

* fix(responses): log each MCP tool call under its own id so a failed follow-up keeps its spend row

The non-stream auto-execute path passed the request's call id to the tool call, so the tool's spend row and the request's failure row shared one request_id and the failure row was dropped on insert, leaving the paid first round unbilled.

* fix(responses): bill round 1 on a client disconnect, keep MCP tool rows in the request's session, and charge a fixed margin once per request

* fix(responses): keep bridged MCP auto-execute in one session and trace and continue its conversation

The bridged follow-up no longer chains on round 1, so a thinking model keeps its reasoning and the request stays in one session. The tool call log continues the request trace without renaming it, the tools are fetched once, and a later turn finds the MCP turn under the id the client got, skipping the tool rows.

* fix(responses): log the non-stream MCP tool listing in the request's session and trace

* fix(responses): find a bridged MCP turn by the id the client holds and log its listing in the bridged trace

* fix(responses): derive the MCP tool row id from the request's call id

The tool call's spend row now uses <call id>_<tool call id>, so it stays
linked to the request without colliding with the request's failure row.
Also tighten the internal cache-hit test to a fixed clock and typed params.

* fix(responses): bill a retried MCP attempt for its own rounds

A router retry or fallback reuses the request's logging object, so a failed attempt's stashed round 1 usage made the next attempt's success row log stale tokens. Each non-stream MCP attempt now starts without that stash.

* fix(responses): bill every failed MCP attempt's paid first round on the request failure

A retry or fallback now sets a failed attempt's stashed round 1 aside instead of dropping it, and the proxy's failure row adds it to the last attempt's own, so a request whose later attempt fails on its first call still bills the round the provider charged. A cached final round also keeps the paid first round's cost breakdown.

* fix(responses): keep MCP tool catalog and results out of the bridged next-turn replay

* fix(responses): keep MCP tool spend, client body keys, and Langfuse traces working on auto-execute

Count the MCP tools an auto-executed Responses API call ran in the tool spend rollup, accept a client body key named previous_response_client_ids without a 500, and point MCP listing and tool spans at the trace Langfuse gives the parent request, including x-litellm-session-id requests

* fix(responses): join MCP spans to the Langfuse trace when the request sends body metadata

* test(integration): cover non-stream MCP auto-execute billing, failure rows, and bridged follow-ups

feat(agents): support Databricks Agent Platform agents in the agent gateway (#45681)
* feat(agents): support Databricks Agent Platform agents in the agent gateway

Add a databricks_agent provider that speaks the MLflow ResponsesAgent wire
(Responses-shaped input, output_text items, output_text.delta SSE) to Model
Serving endpoints (/invocations or the unified /serving-endpoints/responses)
and Databricks Apps (/responses), with a PAT or OAuth M2M client credentials

Register it through the agents config block or the Admin UI agent catalog and
call it through /a2a/<agent> (message/send, message/stream) or model:
a2a/<agent> chat completions. The chat route now runs every completion-bridge
agent through its own provider, and attaches the minted Databricks OAuth token
for both bridge and URL agents. Consumed OAuth settings never reach the
provider call

* fix(agents): harden databricks_agent input, output, and OAuth handling

Non-text content parts answer 400 unless drop_params is set, a reply without
an output list answers 502, flat OAuth fields resolve an os.environ api_base,
the bridge debug log no longer echoes the request model, routing tests stub
only the HTTP boundary, and the catalog description fits the dropdown

* fix(agents): merge agent and client extra_headers on the a2a chat route, and reject an empty databricks_oauth block

* fix(agents): bridge only databricks_agent agents on the a2a chat route, keep the card url over a client api_base, and require workspace_url for a Databricks App

* refactor(agents): read the a2a chat bridge providers from a constants set instead of branching on a provider name

* fix(databricks_agent): let the configured credential win, reject malformed client extra_headers, and keep a missing endpoint name empty

* test(agents): drive the flat OAuth a2a send through the real bridge

* fix(agents): keep an empty databricks_oauth block ignored on url agents, as before this change

* fix(agents): accept bare App hosts, env service principals, and os.environ refs on Databricks agents

* fix(databricks_agent): address review caveats on chat bridging, params, and auth

Map max_tokens and max_completion_tokens to max_output_tokens and pass
temperature, top_p, and user, so /v1/messages works without drop_params.
Send A2A message metadata only with string values, answering 400 or
dropping the rest under drop_params. Join message items with a blank line
in both stream and non-stream replies. Cache the env service principal
token until shortly before it expires. Keep databricks_agent replies out
of the response cache.

On the chat bridge, let request fields win over the agent's stored params
while pinning the agent's api_base and api_key, and apply the agent's
static_headers between client and agent extra_headers, as /a2a does.
Resolve os.environ/ only for databricks_agent api_base and api_key instead
of every bridge provider. Ignore an unusable databricks_oauth block on URL
agents on chat, as at the merge base, instead of answering 400.

* test(internal_context): list the databricks agent token cache as process-local

* fix(databricks_agent): keep the agent's endpoint, input, and target out of client control

extra_body model and input answer 400, or are dropped under drop_params.
A client api_base or base_url never replaces the agent's card URL on the
bridge. Chat to a URL agent keeps its merge-base call, and an incomplete
databricks_oauth block on a URL agent keeps its merge-base ValueError.

* test(databricks): expect the merge-base 400 for a client api_base on agent chat

* fix(databricks): keep agent-owned inputs and identity headers out of a chat caller's reach

* fix(databricks): bound the agent-over-caller merge to two levels so it needs no recursion

feat(gemini): accept file content blocks with video_metadata on multimodal embeddings (#45305)
* feat(gemini): accept file content blocks with video_metadata on multimodal embeddings

* test(gemini): annotate the embedding mock helper and keep the type comment short

* fix(gemini-embeddings): keep file blocks through a partial embedding cache hit and validate video_metadata strictly

* test(caching): type the partial-hit cache test and pin its clock

* fix(gemini-embeddings): accept the Files API URI /v1/files returns as a file block's file_id

* fix(gemini-embeddings): 400 on bad input shapes, drop unknown block keys under drop_params, cache multi-block inputs

A bare object `input` answered 500 from both the caching handler and the
transformation; both now answer 400. An unresolved `files/` reference on
vertex_ai/ answered a ValueError 500; it now answers 400 naming the gemini/
provider. An empty `format` passed through to the provider; it now answers 400
naming file.format. Unknown block keys (`detail`, an unknown video_metadata
key, a top-level block key) are dropped under drop_params, global or
per-request, and still answer 400 without it. The embedding cache counted
file blocks against `max_messages`, so a request with 5 or more blocks was
never cached; file blocks no longer count.

* fix(caching): answer 400 for an object embedding input on the cache lookup

* test(gemini-embeddings): annotate the new embedding tests with return types and Final

* test(gemini-embeddings): annotate the transformation and files batch tests with return types and Final

Integration cells for gemini/ and vertex_ai/ embedding file blocks with video_metadata: the batchEmbedContents and embedContent wire shapes, format overrides, nested and repeated inputs, every malformed block answering 400 before any provider call, drop_params at the request, deployment and YAML levels, the OpenAI SDK sync and async clients, Redis cache fills, hits, partial hits and the metadata in the key with zero-spend hit rows, chat, responses and messages controls, the vertex_ai/ batch JSONL upload, a mixed fast/slow/malformed/dropped burst and a worker kill. The wire peer now reads chunked request bodies, which the streamed GCS media upload sends

* test(integration): treat an upload the client abandons before its terminating chunk as a disconnect, never a stored request

fix(caching): never store or serve a chat completion with no choices (#44709)
* fix(caching): never store or serve a chat completion with no choices

A provider response with empty choices was written to the response cache and served on every identical request until the TTL ended, with no provider call in between. The cache now skips storing such a response and treats an already stored one as a miss, so the next request goes back to the provider and its answer replaces the entry.

* fix(caching): skip responses with no output on the Responses API and Anthropic Messages too

* fix(caching): skip streams and stored entries that carry no output

A chat or text completion stream whose chunks carried no choice is closed
by the stream wrapper with one empty choice of its own, so the assembled
response passed the choices check and was cached. The assembled stream is
now judged on its content: a stream with no text, tool call, or other
output in any choice is never stored, on the async and sync writers alike.
The Responses API stream writer and the Anthropic Messages stream writer
apply the same no-output check before storing.

A stored entry with no output read through the worker memory tier is now
evicted from that tier on the miss, so the next read reaches Redis where
the refill lands; the text completion and messages writers only write to
Redis, and the memory copy otherwise kept missing until its own TTL.

* test(integration): response cache cells for answers without output

Deterministic cells for the response cache on every unified endpoint,
streamed and not, through the OpenAI and Anthropic SDKs and raw httpx,
plus the sync SDK paths, stale entries, malformed answers, per-request
TTLs, cache delete, and chaos (Redis stopped or paused mid burst, a
worker killed, in-memory cache mode). The scripted upstream counts only
POSTs as deployment calls, since the proxy's boot-time GET /v1/models
discovery of a config deployment is not one.

* test(caching): pin the stored entry timestamp in the worker-copy test

* test(integration): drop the restating comments from the chaos cells

* test(integration): close the breaker on the first call after the Redis restart

fix(otel): nest cache spans under their operation and name service spans by purpose (#44150)
Response cache reads and writes open cache.get llm_response and cache.set llm_response phase spans with their Redis spans nested underneath, on the Python path and on the native Rust path, and deployment selection runs inside a route {model_group} phase so the cooldown, usage and model-id reads the router issues nest under it before chat {model}. The autorouter classifier call nests under that route phase as well and carries its typed internal origin on litellm.request.purpose, so it is told apart from the provider attempt. Service spans are named {service}.{verb} {target} from a low-cardinality key family the producer declares (llm_response, auth_objects, spend_counters, router_cooldowns, claude_code_session_router_binding, rate_limits, pod_lock, budget_reset, ...) instead of the raw method or a per-request pipeline length; a pipeline flush is targeted by the one family its ops share or by mixed with the sorted families on litellm.redis.families, a batch op keeps the family it was declared under whichever pipeline or standalone read settles it, and the ambient family labels Redis spans only, never the DB write-back a task spawned inside that context performs later. The raw method stays on litellm.service.call_type and on the Prometheus and Datadog labels. Caller attribution is carried across asyncio task boundaries on a ContextVar so forwarder-only chains no longer surface, the raw cache key is dropped from Redis span metadata, pipeline op counts land as an integer attribute, every call_type the Redis cache layer emits maps to a verb, and a scan over litellm/ and enterprise/ fails when a Redis producer, batch reservation included, declares no key family.

A V2 logger built for a key or team logging entry while the operator's V2 logger is already registered keeps only the exporters its own preset contributed, whether or not the operator holds credentials for that backend, so every chat span no longer reaches the operator's collector twice. A span the success callback has to open itself, with no pre-call carrier, starts at the provider handoff (api_call_start_time) instead of the logging object's creation.

fix(otel): detach post-response service spans by request phase, name redis spans by operation (#43237)
* fix(otel): detach post-response service spans by request phase, name redis spans by operation

Service spans logged from the post-response phase (success callbacks, the response-cache write) now root their own trace linked to the request span even while the server span is still recording, instead of only when they happen to end after it. Redis service spans are named `redis <operation>`; the litellm call chain that issued them moves to the `litellm.service.caller` attribute via a typed `ServiceLoggerPayload.caller` field.

* fix(otel): mark anthropic messages stream cache write as post-response phase

The /v1/messages streaming cache writer awaits async_add_cache inline
instead of going through create_cache_write_task, so its redis span
stayed parented under the request trace. Wrap the write in
post_response_phase so it detaches like the chat completions write.

test: move tests/test_litellm core utils, routing, responses, caching and rust_bridge into tests/unit (#43199)
* ci: run the unit_selection.sh shard files on every event instead of only fork pull requests

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

* ci: rename fork-flag to unit-flag now that it applies on every event

* test: move tests/test_litellm root and small trees into tests/unit

Pure renames, no content changes. Follow-up commits in this PR fix
references, merge the three files that already existed in tests/unit,
keep live-provider tests in tests/test_litellm and wire CI.

* test: carry tests/test_litellm conftest isolation into tests/unit

Callback lists, routing fallbacks, cached HTTP clients, logger state, AWS,
proxy-URL and keychain env, and session-end client cleanup now reset for
unit tests too. The environment isolation owns its MonkeyPatch so a test's
own monkeypatch is undone before the model-cost teardown runs.

* test: merge, split and prune the moved root and small-tree tests

Merge batches/test_batch_utils.py and the chat_completions and messages
dispatch tests into the files that already existed in tests/unit. Keep
the live Gemini interactions tests, the async image-fetch format test and
the OpenAI embedding scorer test in tests/test_litellm since they need
real network or keys. Put test_router.py under tests/unit/test_router so
the existing package no longer shadows it. Delete eight tests the audit
found superseded by stronger ones kept in this move.

* ci: run the moved root and small-tree tests under their legacy flags

Add the misc and responses-caching-types flags to unit_selection.sh and
CircleCI, extend enterprise-routing and mcp-integration, and point the
legacy GHA shards, Makefile, redis-compat workflow, merge smoke manifest
and change classifier at the new paths.

* test: make the new tests/unit directories packages

tests/unit/test_package_layout.py requires every directory to carry an
__init__.py, and without one the moved and retained
test_litellm_responses_bridge.py modules collide on import.

* test: scope the unit socket block to tests/unit in shared sessions

The GHA shards collect the legacy test-path and the unit selection in one
pytest session. The unit conftest's loopback-only block leaked into legacy
modules that reach the network at import. The legacy conftest now lifts the
restriction at collect and setup time, and the unit conftest re-applies it
when collecting its own modules.

* test: move tests/test_litellm/llms into tests/unit/llms

Rename-only. Moves the provider tests and the fine-tuning fixtures they
load, mirroring the old paths. Follow-up commits merge, split and wire them.

* test: merge, split and prune the moved llms tests

Merges the Databricks chat transformation tests into the existing unit
file, keeps the tests that need real keys or the network in
tests/test_litellm, deletes the audited tests a stronger unit test
already covers, and points imports at tests.unit.llms.

* ci: run the moved llms tests under their legacy flags

The Vertex AI and All Other Providers shards keep their legacy test-path
for the retained files and add the llm-vertex-ai and llm-other-providers
unit selections. CircleCI gets matching unit jobs.

* test: make the tests/unit/llms directories packages

Adds __init__.py to the moved dirs and drops the legacy ones whose
directories no longer hold tests.

* test: drop script runners and path hacks the llms split left dangling

The __main__ runners in the split openai_like files and the Databricks e2e
runner called tests that now live in the other half of the split or were
deleted. The retained legacy halves also no longer need sys.path edits.

* test: give the shard-script tests their own GITHUB_OUTPUT

They only passed where the runner set it. The CircleCI unit job's env
allowlist drops it, so the script's redirect failed there.

* test: point the router and module-deletion checks at tests/unit

router_code_coverage and code_qa_check_tests only searched tests/test_litellm,
so the moved router tests no longer counted. The two silent-experiment tests
the audit deleted were the only direct callers of those methods; they are
replaced with tests that assert the forwarded shadow request and the
recursion guard.

* test: move tests/test_litellm integrations and secret_managers into tests/unit

Rename-only. Mirrors the old paths, including the directory conftests
and the prompt and JSON fixtures. Follow-up commits prune and wire them.

* test: prune and repoint the moved integrations tests

Deletes the 7 audited tests a stronger test in the same tree already
covers, imports the TLS sink helpers from their new conftest path, and
restores os.environ after each integrations test. Some presets write
OTEL_EXPORTER_OTLP_HEADERS straight into os.environ, and without the
legacy tree's test ordering that header leaked into the AgentOps tests.

* ci: run the moved integrations tests under their legacy flag

The integrations GHA shard and a new CircleCI job run the integrations
unit selection. secret_managers joins the misc selection.

* docs: point integrations and secret_managers references at tests/unit

* test: make the moved integrations directories packages

* test: keep the Databricks manual e2e runner and fix the SageMaker Nova run path

The Databricks e2e file is a manual script whose main() calls the tests
that were pruned, so pruning them broke the documented run. It is back to
its main version. The SageMaker Nova docstring now points at the file's
real location in tests/local_testing.

* test: move tests/test_litellm core utils, routing, responses, caching and rust_bridge into tests/unit

Rename-only. Mirrors the old paths, including fixtures, the stubtest config
and the native-route wheel script. Two files that collide with existing unit
files are merged in a follow-up commit.

* test: merge, prune and repoint the moved core, routing, responses, caching and rust_bridge tests

Merges the two files that collided with existing unit files, folding the
legacy extra case into test_is_chat_completion_cached_dict, and deletes the
9 audited tests a stronger test in the same file already covers.

Keeps what needs the network in tests/test_litellm: test_tokenizers pulls a
tokenizer from the Hugging Face hub, and the gpt2 and r50k_base tokenizer
cases download their BPE files. The unit core_utils conftest points
TIKTOKEN_CACHE_DIR at litellm's bundled encodings so the rest never depend on
import order to stay offline, and FakeSecretVault moves to a shared module
so both trees can build it.

* ci: run the moved core, routing, responses, caching and rust_bridge tests under their flags

core_utils gets a core-utils flag and CircleCI job, and its GHA shard keeps
the legacy path for the retained network tests. router_utils and
router_strategy join enterprise-routing, responses joins
responses-caching-types (minus responses/mcp, which mcp-integration owns),
caching joins caching-local and rust_bridge joins misc. The redis-compat,
test-rust, stubtest and merge-smoke paths follow the move.

* docs: point the Rust crate references at tests/unit

* test: make the moved core, routing and rust_bridge directories packages

* test: keep the no-loop DualCache batch_get_cache regression test

It runs the sync path outside any event loop, which the inside-loop test
cannot, so a change that picks the Redis client by loop state would only
show up there.

* test: keep the job's UNIT_FLAG out of the shard-script tests

* fix(url_utils): block 192.0.0.0/24 on every Python patch release

* test: move the new budget limiter tests into tests/unit/router_strategy

* test: move the new sentry scrubbing tests into tests/unit/litellm_core_utils

* test: move the new zerobus tests into tests/unit/integrations

* test: make tests/unit/integrations/zerobus a package

* test: load litellm's own tiktoken cache setup once instead of resetting it per test
