Bedrock retired cohere.command-r-plus-v1:0 on 2026-08-19 and lists no
Cohere command chat model anymore, so the three local_testing cases that
pinned it fail with a 404 end-of-life error on every pipeline. Drop the
case from test_completion_bedrock_httpx_models and move the
parallel-streaming Bedrock entry to mistral.mistral-7b-instruct-v0:2,
which still takes the invoke route and is ACTIVE in the CI account.
test_router_timeout, test_timeout_streaming and test_openai_embedding_timeouts
asked api.openai.com for a response in 10 to 100 microseconds and asserted the
resulting exception was a timeout. No connect can finish in that window, so
socket.create_connection always walked the whole address list, and because it
re-raises only the LAST address's error, the assertion was decided by the order
getaddrinfo happened to return.
api.openai.com is dual-stack and the CI container has no usable IPv6, so a
trailing AAAA record made the last attempt fail with an OSError. httpcore maps
socket.timeout to ConnectTimeout but OSError to ConnectError, so the expected
APITimeoutError arrived as APIConnectionError and the job went red. The three
tests were really measuring DNS ordering, not litellm.
Point them at the fake OpenAI endpoint the suite already runs, ask for the
slow-endpoint model it already delays on, and give them a timeout comfortably
under that delay. The embeddings route did not honour slow-endpoint yet, so it
now delays the same way chat and text completions already do.
Each test also gained a failure on the success path. Without it a request that
returned instead of timing out fell out of the try block and the test passed on
a result it was written to reject.
This reverts merge commit 2b1bd20834 (#31125)
Two CircleCI jobs on the staging-to-main promotion went red the moment
that PR landed. proxy_multi_instance_tests boots two proxies against one
database, and both now race the same migration:
Error: P3018 A migration failed to apply
Database error code: 40P01, deadlock detected
Process 73 waits for ShareLock on virtual transaction 4/11;
blocked by process 75. Process 75 waits for ExclusiveLock on
advisory lock [16384,0,72707369,1]; blocked by process 73
Neither proxy comes up, so the job times out after 300s waiting on
localhost:4000. The same wait took 36.5s on the last green run
Timeline: #31125 merged at 18:46:14Z and the failing run started at
18:49:59Z. The merge commit is not an ancestor of the last green
revision (194a3cc) and is an ancestor of the first failing one
(01de2837)
The v2 resolver was meant to avoid exactly this class of contention, so
the deadlock looks like a bug in it rather than a reason to abandon it.
Putting the default back to v1 buys time to fix it without holding up
the release
The omitted-format path deliberately no longer dispatches through
embeddings.create, so four legacy tests now intercept at the transport or
client.post instead. Also adds a bypass error-path unit test, rewords a stale
comment and a README scope note, and ratchets the lint budgets down.
Consolidate the new regression tests into
test_openai_embedding_encoding_format_default.py, replacing mocks that
pinned the old float default with respx captures of the request body,
and update the stale local_testing default-float test to assert
omission
The v2 resolver skips the diff-and-force recovery that caused schema
thrashing when two LiteLLM versions contend for one database during a
rolling deploy. The standalone migration Job already defaulted to v2; this
aligns the proxy-server path.
v1 stays reachable two ways: --use_legacy_migration_resolver on the CLI, and
USE_V2_MIGRATION_RESOLVER=false for containerised deploys, where
prisma_migration.py calls run_server with a fixed argv and the env var is the
only route in. --use_v2_migration_resolver still parses, so existing commands
do not die on an unknown option.
Because v2 fails fast where v1 retried every failed deploy, a database that is
not accepting connections yet, or another instance holding the migration
advisory lock, would now kill a boot that used to ride it out. Those two
failures are retried, with Prisma's stderr logged each round, and still raise
once the attempts are spent.
Moves the resolver tests from litellm-proxy-extras/tests, which no CI job
runs, into tests/litellm-proxy-extras, and repoints the dedicated Postgres
CircleCI job at the legacy path so v1 keeps real-DB and proxy-boot coverage.
batch_completion collects per-request failures into its result list rather than
raising them; its own source says "return exceptions if any". So the test's
`except Timeout` and `except litellm.InternalServerError` arms could never fire for
the case they were written for. An upstream 500 instead reached
`response.choices`, raised AttributeError on the exception object, and fell through
to the bare `except Exception` that calls pytest.fail. That is what CircleCI hit.
The tolerance now reads the returned values, which is where the failures actually
are. The same two exception types are tolerated as before, nothing broader.
Checked against four injected outcomes: three InternalServerErrors pass, three
Timeouts pass, an AuthenticationError fails, and a response whose content is None
fails. So it is not tolerating its way to a vacuous green.
test_opik_logging_http_request asserted "nothing has been POSTed yet" roughly one
second into a window governed by OpikLogger's 5-second periodic flush. On a loaded
CI worker the five preceding acompletion calls eat that budget, the periodic flush
fires, and the assertion flips. Reproduced with no product changes at all: letting
5.5 seconds pass before the assertion drains the queue and sets mock_post.called,
which is exactly the failure CircleCI reports.
The test now pins flush_interval past anything the test can reach, so the two
batching assertions measure batching instead of wall clock, and drives the flush
path explicitly at the end rather than sleeping the interval. That last phase used
to be near-vacuous, since the size-triggered flush had already emptied the queue.
Assertions now match only calls to Opik's own /traces/batch and /spans/batch.
get_async_httpx_client caches one client per special provider, so the mock is
process-wide and any other logging callback's POST would otherwise count.
Dropped the teardown that closed that shared client, which broke every later test
in the same worker that logs through it, and the try/except that turned assertion
failures into a pytest.fail with no traceback.
Mutation checked: flushing on every event and never flushing on size both fail the
test.
- test_custom_callback_input: audio redaction assertion expects None content
(redaction leaves None untouched, gpt-audio-1.5 returns content=None)
- local_testing conftest: drain GLOBAL_LOGGING_WORKER in isolate_litellm_state
teardown so mocked-router tests stop leaking pending logging tasks into
test_gcs_pub_sub
- test_together_ai: tools is always a supported param now; only response_format
is gated by function-calling support
- test_keys: /team/new omits models instead of sending null (422), so the key's
team really exists and auth no longer raises TeamNotFoundError
- test_team_delete_member_add_race: per-test unique team and user ids so xdist
workers sharing one Postgres stop deleting each other's team mid-race
* test: drop the cwd-relative sys.path.insert calls from the test suite
TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.
Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.
Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.
* test: drop the duplicate imports the sys.path sweep exposed to F811
* test(pre-call-utils): restore the os import the new bedrock tests need
* test: unshadow the module handles the F811 sweep left behind, and pin the two live tests that went red with it
The F811 sweep in #37878 removed the fixture-local `import litellm` from four
conftests, but the bare `import litellm.proxy.proxy_server` a few lines below
still binds `litellm` as a function local, so `importlib.reload(litellm)` runs
before the name is assigned and every test in those directories errors at
setup. The `hasattr` guard on the line above already proves the module is
loaded, so the import only ever bound the name. Drop it, and enable F823 in
ruff-tests.toml, which flags all four sites at the failing line and would have
blocked the sweep
The same sweep renamed the `check_non_streaming_response` parameter but left
one read of `completion`, which now resolves to `litellm.completion`, and
removed an import whose side effect was the only thing making
`litellm.proxy.proxy_server` reachable in the moderation hook test. That test
already takes `monkeypatch`, so patch the router through it and stop leaking
the router into later tests
`test_content_policy_exception_openai` passed vacuously until #37887 turned it
into a real `pytest.raises`, and OpenAI no longer rejects a lyrics prompt with
a content policy error. Inject an AsyncOpenAI client whose transport answers
with OpenAI's own `content_policy_violation` rejection so the mapping to
ContentPolicyViolationError is exercised every run
`test_async_create_batch` hit a 409 cancelling a batch OpenAI had already
marked failed. The cancel step tolerated a completed batch but not a failed
one. Fold both guards into one helper that tolerates a failed batch only when
OpenAI's recorded error is the org's enqueued token limit, and prints the
batch's errors so the reason is in the log either way
* test: close the injected AsyncOpenAI client after the content policy test
* chore(lint): ratchet TQ005 down by the global mutation this branch cleared
* chore(lint): ratchet TQ005 to 2660 on the merged tree
* chore(lint): ratchet TQ005 to 2561 on the merged tree
* chore(lint): ratchet TQ005 to 2548 on the merged tree
Four more ruff rules for code the test suite runs but never checks. F601 is the
one that paid: the duplicate key it flagged in a get_form_data fixture was the
mock reproducing the production bug fixed in the previous commit.
B025 removed two unreachable handlers, one of them a pytest.skip shadowed by an
earlier `pass`, so an upstream Vertex flake reported green having asserted
nothing. F632 turned an `is ""` identity check, which passes only on CPython
interning, into the `== ""` it meant. B023 fixed three closures over loop
variables, all latent today but one iteration-order change away from checking the
last case N times.
A test that asserts on the error inside its own except block passes when the
call stops raising, because nothing runs the handler. That is the exact case
the test exists to catch, so the regression lands green.
Rewrites all 111 such blocks into pytest.raises, which fails when the call
succeeds, and selects PT017 in ruff-tests.toml so no new one lands.
A name bound twice keeps only the second binding. In `tests/` that is nearly
always a repeated import, harmless but misleading, and the same rule is what
catches the cases that are not harmless: a local that shadows an import the
module still calls, and a second `def test_x` that quietly replaces the first.
311 of the 344 sites were repeated imports and came out with ruff's own fix.
The remaining 33 needed a decision. Four modules imported a name they never
used because a local definition below already shadowed it. Two comprehensions
bound `call` over `unittest.mock.call`, which those modules import and use.
One test rebound the two module handles its nested reload closure had captured.
One class attribute shadowed an unused `status` import.
The load-test fixtures move to a conftest, which is how pytest is meant to share
them, so the test module no longer imports three fixture names it never calls.
The nine `prisma_client` parameters keep a narrow `noqa`: pytest resolves that
fixture by name before the body runs, so the parameter never shadows anything.
`pytest.raises(Exception)` with no `match=` passes on any error that broad. A
TypeError from a refactor, a botched fixture, an import that moved: all of them
read as the rejection the test claims to police, so the test goes green for the
wrong reason and stays green after the behaviour it guards is gone.
PT011 closes that gap for the 317 sites B017 could not reach, because B017 only
fires on a single-statement body with no `as e` binding. Each pattern here is the
message the code actually raised, recorded by running the sites under a plugin
that logged the concrete type and text per call site, so the assertions describe
observed behaviour rather than a guess. Where a site raises more than one message
across its parametrize cases, the pattern is an alternation of what was seen;
where the exception carries an empty `str()` and puts the text on `.message`, the
site keeps a narrow `noqa` with the reason.
PT014 removes four parametrize cases that were listed twice. The duplicate re-runs
an assertion that already passed, and it usually marks a case someone meant to
vary and forgot to edit.
* test: enforce PT012 so a pytest.raises block cannot hide dead assertions
`with pytest.raises(...)` stops at the first statement that raises. Anything
sequenced after it inside the block never runs, so an assertion written there is
never checked and the test still reports green.
Two sites were doing exactly that, and both assertions turned out to be wrong
once they started running. tests/llm_translation/test_prompt_factory.py asserted
the bedrock rejection names "requires at least one non-system message", which
holds. tests/proxy_unit_tests/test_proxy_server.py asserted the prisma startup
failure mentions "httpx.ConnectError", which never appears: the failure is an
httpx.ConnectError whose message is "All connection attempts failed", so that
test now asserts the type. Its DATABASE_URL override moves to monkeypatch, since
the old restore sat below the assertion and leaked the invalid URL into every
later DB test the moment the assertion started being able to fail.
The remaining 72 sites are rewritten without changing what they exercise: setup
that cannot raise moves above the block, a nested `patch` moves outside it, and
bodies with real control flow (a stream drain, an if/else on sync_mode, a
retry loop) move into a local closure the block calls.
Fixing PT012 unmasked two B017s, since ruff only reports a blind
pytest.raises(Exception) once the block holds a single statement.
tests/proxy_unit_tests/test_auth_checks.py narrows to the ProxyException
can_key_call_model actually raises. tests/local_testing/test_completion_cost.py
was asserting vertex_ai/medlm-medium has no cost entry, which stopped being true
at some point; that dead first half is gone and the rest of the test, which
checks medlm pricing resolves above zero, now runs instead of being skipped.
* chore(ci): ratchet TQ004 to 768 after the prisma test moved to monkeypatch
Every live together_ai call in CI has answered 503 Service unavailable since
2026-08-20, across two runs 2.5 hours apart, while Together's status page
reported no incident in either window. These are real calls, not replayed
cassettes: the VCR layer runs filter_non_2xx_response, so a 503 is never
written to a cassette and cannot be replayed back.
Qwen/Qwen2.5-7B-Instruct-Turbo does not appear anywhere on Together's monitored
component list, whose Qwen entries are all Qwen3.x, so a model-level outage
there would never surface as an incident. The same 503 already forced
test_basic_rerank_together_ai to be skipped on a different together_ai model,
so per-model 503s are an established failure mode here rather than a platform
outage.
openai/gpt-oss-20b is the cheapest together_ai entry that carries real pricing
and the capabilities these suites exercise, at $0.05/$0.20 per 1M tokens with
function calling, response schema and tool choice. Together monitors it as a
served component. The retired model also carries null pricing in the cost map,
which is its own liability now that unpriced models are blocked.
test_multiple_deployments.py keeps the old id: it is a router fallback list
that is green today, and busting its cassette to prove a point would trade a
passing test for a live call this change cannot vouch for.
* test(lint): ban blind pytest.raises(Exception) with ruff B017
A bare pytest.raises(Exception) accepts whatever the body throws. The TypeError
a refactor introduces satisfies it exactly as well as the rejection the test was
written for, so the crash reads as a pass and the test never goes red.
All 111 existing sites are narrowed here. A runtime probe recorded the concrete
exception each one actually catches, and each site now names that type. Where
the code under test genuinely raises a bare Exception, the site pins a stable
slice of the message with match= instead.
Two sites tell on themselves. The shared responses-API cancel test raises
"custom_llm_provider is required but passed as None" rather than talking to a
provider at all, because cancel_responses takes a provider, not a model. And
test_bedrock_guardrails_with_streaming was the only test in its file still
passing without AWS credentials, because the NoCredentialsError boto3 raised
long before the guardrail ran satisfied the blind raises.
* fix(test): widen the openai batch-dispatch assertion to OpenAIError
The narrowed NotFoundError only holds where OPENAI_API_KEY is set. Without one
the SDK raises OpenAIError while building the client, long before any 404, so CI
went red. OpenAIError covers both and still rejects a TypeError from a refactor.
* test(ci): serve /moderations from the canned OpenAI mock
The otel proxy E2E job points its `openai/*` wildcard deployment at the
canned mock, and #37492 made `get_model_list` agree with
`get_available_deployment` on bare model names. /moderations now resolves
`omni-moderation-latest` to that wildcard deployment the way
/chat/completions already did, so the request lands on the mock, which
never implemented the route and answers a bare 404.
Add /moderations and /v1/moderations to the mock, returning an
OpenAI-shaped response with one result per input item.
* style(ci): annotate the new moderations locals as Final
`assert False` inside a `try:` raises AssertionError, which the `except
Exception` right below it catches, so several tests reported green no matter
what the code did. `pytest.fail` raises Failed, a BaseException, and escapes.
A bare `a == b` statement is evaluated and discarded. Nine of those sat in
tests, and one was comparing against a model name the router never produces.
Selects B011, B015, B018, PT015, PLR0133 and PLW0127 in ruff-tests.toml
alongside F821, with all 50 existing violations fixed, so no budget file or
ratchet is needed. CI already runs this config over tests/.
ruff.toml excludes tests/* from `ruff check`, so nothing has ever checked the
test tree for names that do not exist. That matters more in tests than in
product code: a NameError inside a test whose body is wrapped in
`except Exception: pass` is swallowed, and the test reports green forever.
Adds ruff-tests.toml selecting F821 alone, wired into the lint workflow and
`make lint-ruff`, and clears every existing violation:
- 4 tests interpolated an unbound `e` into a `pytest.fail` message reached only
on the failure path, so the NameError, not the assertion, is what ran.
test_llm_guard_error_raising is the worst: it passes today with content
safety disabled entirely. It now asserts the 400 and its detail body.
- 5 sites construct BaseExceptionGroup, a 3.11 builtin, in a tree that still
supports 3.10. Guarded behind the exceptiongroup backport that anyio already
pulls in below 3.11.
- 9 missing imports (json, openai, Any, Final, HTTPException), including one in
a helper that catches HTTPException by a name it never imported, so the
challenge path it exists to detect raises NameError instead.
- 5 annotations naming types imported inside the function body, hoisted to
module scope or TYPE_CHECKING.
- 2 blocks of dead code: everything after a pytest.fail in
test_claude_agent_sdk, and an unused helper in test_end_users calling a
function defined in a different module.
- 1 error-path f-string in the router-settings doc test that masked the real
FileNotFoundError behind a NameError.
Only F821 for now. Widening the select list means ratcheting thousands of
pre-existing findings, so rules go in one at a time with their violations
already fixed.
* test: replace blind sleeps with deadline waits in callback and caching tests
tests/local_testing/test_custom_callback_input.py slept a fixed 1-3s after
every call and then asserted the callback handler recorded no errors. Because
the handler only appends to `states` when a callback actually fires, an assert
of `len(errors) == 0` passes just as happily when nothing fired at all, so the
sleep was buying flakiness in exchange for a vacuous check. The async tests
were worse: `time.sleep` blocks the event loop, so the success/failure tasks
scheduled on it could not run before the assertion.
Adds tests/_wait_helpers.py with `wait_until` / `await_until`, which poll a
predicate against a deadline, and converts all 17 sites to wait on the thing
the test actually cares about (the terminal state landing in `states`, or the
patched log hook being called). The waits assert the callback fired, so these
tests now fail on a dropped callback instead of passing silently.
The three sleeps in test_caching_handler.py sat between `sync_set_cache` and
`_sync_get_cache`, both fully synchronous against a local in-memory cache, so
they are just deleted.
* fix(test): wait on the priming call's own logging in the cache-hit test
The 3s sleep in test_logging_async_cache_hit_sync_call was not waiting for the
cache write, which lands before the stream iterator is exhausted. It was
waiting for the priming call's success callback to drain, so the handler
installed right after it only ever sees the second, cache-hit call. Waiting on
a populated cache_dict let the priming call's still-pending log_success_event
reach the new mock, and the test then read cache_hit off the wrong payload.
Waits on the priming handler's own sync_success state instead.
Python binds a name once per scope, so when a module or class defines the same
test twice only the last one exists. The earlier definitions are unreachable:
pytest never collects them, and nothing that references them can fail.
A sweep in August cleared nine of these. Five have appeared since, which is the
argument for a rule rather than another sweep.
Each survivor is the better version, so nothing is lost. The two SQS logger
twins additionally stub `asyncio.create_task`, which the shadowed copies did
not. The cost-calculator duplicate is a two-line stub that also takes a
`model_item` parameter no fixture supplies, so it could not have run even
unshadowed. The two `test_prompt_caching` bodies are both `pass`.
Collecting the four files reports 416 tests before and after.
`tests/proxy_unit_tests/conftest copy.py` goes with them. pytest only loads a
file named exactly `conftest.py`, nothing imports this one, and the space in the
name says what it was.
The earlier sweep only caught the conformance suite in tests/llm_translation.
Groq retired llama-3.1-8b-instant alongside llama-3.3-70b-versatile, and four
tests under tests/local_testing still call them for real, so litellm_router_testing
and both local_testing shards 404 with model_not_found.
Only the sites that leave the process move. The chunk fixtures in
test_stream_chunk_builder, and the cost and routing tests that never open a
socket, keep the old ids because the string is data there, not a request.
* feat(complexity_router): custom classifier plugins via classifier_type 'plugin'
Adds a third classification mode where an operator-supplied hook decides the
tier instead of the heuristic scorer or the LLM classifier. The hook implements
an async classify(context) returning a tier name (built-in value, tier_labels
label, or tier_definitions name) or None to decline; failures, timeouts, and
unknown tiers fall back exactly like a failed LLM classifier. The context
carries the request messages and metadata, including caller identity, so a
plugin can route by team, spend, or any business rule.
The plugin resolves from a dotted path at proxy startup with a load-time check
that classify is a coroutine function, and is closed off over HTTP like the
routing plugins list. Routing decisions record the new classifier_plugin cause.
tier_definitions now accepts classifier_type 'plugin' alongside 'llm'.
* fix(proxy): resolve plugin dotted paths in _delete_deployment before hashing ids
The db-sync reconcile re-reads the raw config and hashes litellm_params to
compute which ids the config wants served, but the router's ids were hashed
from the resolved params where plugin dotted paths are live instances. The
mismatched ids made the reconcile evict every plugin-bearing auto-router one
sync after startup, on any proxy with a database connected. This also affected
the existing routing plugins list, not just the new classifier plugin.
Resolving the plugins in _delete_deployment the same way load_config does makes
both sides hash the same canonical form. A plugin module broken on disk at
reconcile time skips cleanup instead of evicting valid deployments, matching
how a get_config failure is handled
* fix(complexity_router): treat non-string plugin verdicts as declines, centralize the empty-mapping sentinel
A hook returning a non-string raised inside resolve_classified_tier outside the
plugin exception boundary, failing the request instead of falling back. Also
moves the read-only empty mapping to constants.py per repo convention and moves
the classifier plugin product docs out of the package README for the docs repo
* refactor(complexity_router): rename the plugin classifier mode to classifier_type 'custom'
The mode value now names the operator's intent while classifier_plugin keeps
naming the mechanism; routing decisions keep the classifier_plugin cause
* refactor(proxy): pin plugin-bearing deployment ids from the raw params instead of resolving in the reconcile
Replaces the previous approach of re-running plugin resolution inside
_delete_deployment, which imported operator modules on every reconcile cycle
and skipped the whole cleanup pass when any one module was broken on disk.
load_config now stamps model_info.id from the raw litellm_params before
resolution swaps dotted paths for live instances, so the reconcile's raw-config
hash matches by construction and needs no resolution at all: a broken module
cannot stall cleanup for unrelated models, and any future param-transforming
resolution is covered by the same pin. _generate_model_id becomes a staticmethod
so the pin can run before the Router exists; its statically dead non-string key
branches are removed. Also documents candidate_models as an informational
snapshot for classifier plugins, unlike the narrowing surface RoutingPlugin
filters
* fix(router): restore _generate_model_id key handling, align classifier context with the routing-plugin pattern
The staticmethod conversion accidentally dropped the non-string-key branches
from _generate_model_id, a silent hash change for any params with non-string
keys; they are restored verbatim. The classifier plugin context now follows
the Router-level routing-plugin recipe exactly: structured messages come from
resolve_structured_messages over the raw messages, and the metadata key comes
from the shared get_metadata_variable_name_from_kwargs helper, which also
replaces the duplicated inline sniff in _pick_model_for_tier. This removes the
raw-or-resolved fallback where a plugin could silently receive resolved
messages when a call site forgot to pass the raw ones
* refactor(router): make generate_model_id public, guard classifier context construction
Two modules legitimately hash deployment ids with the same helper now (Router
and the proxy's config-load pin), so the private name was lying about its
audience and the cross-module call needed a pyright suppression; renaming it
public restores the static safety net. The classifier plugin's RoutingContext
construction moves inside the failure boundary, matching the LLM path where
litellm-side prompt building also falls back rather than failing the request,
and a prompt-only call with no message list is now covered by a test
Three groups, all verified by running the suite rather than by inspection.
18 files whose every test function carries an unconditional @pytest.mark.skip,
39 test functions in total. They are collected on every CI run and always skip,
so they advertise coverage the suite does not have. Reasons on the marks include
"AWS Suspended Account", "lakera deprecated their v1 endpoint" and "moved to
using 'otel' for logging"; 26 of the marks predate 2025.
30 test functions with a byte-identical body and identical decorators to a
sibling in the same file and class, differing only in name. Deleting one of each
pair removes no coverage. Four further candidates were excluded because they
override an inherited test, where deleting the override un-shadows the base
class implementation instead of removing a duplicate.
9 test functions that a later definition of the same name shadows, so Python
never binds them and pytest cannot collect them.
One file that is a demo script rather than a test; its own docstring says to run
it with python.
Verification: collecting the 26 edited files gives 2,492 node IDs before and
2,462 after. The 30 duplicate deletions account for exactly 30 removals, the 9
shadowed deletions account for 0 (confirming at runtime that they were never
collectable), nothing unexplained disappeared, and nothing new appeared. No
other test or module imports any deleted symbol.
AWS no longer serves `anthropic.claude-3-sonnet-20240229-v1:0`. The streaming
path returns a plain 404, "Model with the provided id
anthropic.claude-3-sonnet-20240229-v1:0 is not found", and the non-streaming
path answers 500 for the same reason. Our own cost map has carried a
2026-07-30 deprecation date for it since #36538
That accounts for 20 failures across local_testing_part1, local_testing_part2
and llm_translation_testing. litellm maps both statuses correctly, so the
tests are what went stale, not the client
Replacement is `us.anthropic.claude-sonnet-4-5-20250929-v1:0`: a like-for-like
Sonnet, and the newest Bedrock Sonnet this repo exercises against the real API
in tests/e2e. Newer ids exist in the cost map, but nothing in the repo calls
them live, so picking one would be an unverified guess about model access on
the CI account
Scope is limited to the tests that actually issue a request. The occurrences
that assert on the model string itself, or that feed mocked transformations,
keep the old id so their assertions stay meaningful
`supports_native_structured_output` was set only on the bare `deepseek.v3.2`
and `zai.glm-5` entries, so the cross-region inference profiles and the
region-pinned ids resolved to None. The flag gates the native
`outputConfig.textFormat` branch in BedrockConverseConfig, so callers
addressing the same model as `us.deepseek.v3.2` or
`bedrock/us-west-2/deepseek.v3.2` silently fell back to synthetic tool
injection. `us.` is the form Bedrock steers callers toward, so the most
common way to reach these models was the one missing the capability.
Adds the flag to the 12 affected ids and keeps the packaged backup in sync.
test_get_model_info_bedrock_models already caught the region-pinned ids, but
it filters on `litellm_provider == "bedrock"` and the cross-region profiles
carry `bedrock_converse`, so reverting just `us.deepseek.v3.2` and
`eu.deepseek.v3.2` left it green. The new parity test covers the prefixed
profiles and fails on exactly that mutation.
The management route-coverage guard fires because /team/metadata_schema landed
in #33353 without a behavior-suite scenario, so this adds one covering the nine
seeded actors plus the unauthenticated 401
The prometheus budget-metric assertions read the log call's first positional
arg, which #35703 turned into an unrendered "%s" format string when it moved
logging to lazy args. They now render the message from the call args, which
also pins the arg order and the exception text that the old substring check
never reached
GitHub Models was fully retired on 2026-07-30, so test_completion_github_api
can no longer pass: the endpoint the github provider targets returns 404 and
models.github.ai answers 410 "github_models_retirement_brownout". The dead live
test is removed rather than skipped
_delete_deployment stopped returning a count of evictions in #35400 and now returns
the frozenset of ids the db and config still want, so a caller judging its own reload
can tell a deliberate eviction from a deployment that went missing. These two tests in
tests/local_testing were left comparing that frozenset against an int and have been
failing since; the directory is only referenced by .circleci/config.yml, which no
longer reports checks on PRs, so nothing caught them.
The eviction behavior itself is unchanged, so the fix is on the assertions: compare
against the expected id set, and pin the router's surviving ids so a mutation that
evicts the wrong deployment is caught rather than passing a bare length check.
aiohttp 3.14.0 and 3.14.1 re-arm the sock_read timer on a keep-alive
connection after it has already been returned to the idle pool. The stray
timer stamps a SocketTimeoutError on the pooled connection without closing
it, so the pool keeps handing it out and the next request to pick it up
fails instantly on an error left behind by an earlier, unrelated request.
Because a single pool is shared across providers, the failures appear
simultaneously across Vertex AI, Bedrock, Anthropic and OpenAI-compatible
deployments as sub-millisecond "Connection timed out" errors.
uv.lock resolved aiohttp 3.14.1 and the published images install via
`uv sync --frozen`, so every image built from that lock shipped the
regression. The wheel's own metadata declared `aiohttp>=3.10,<4.0`, which
also left pip consumers free to resolve into the same broken window, so
both the runtime floor and the uv constraint move to >=3.14.2.
Upstream fixed this in aio-libs/aiohttp#12954, released in aiohttp 3.14.2;
the lock now resolves 3.14.3. Raising the floor rather than capping below
3.14 keeps the advisories that the existing 3.14.1 floor cleared, so no
osv-scanner ignores are needed. litellm requires Python >=3.10 and aiohttp
3.14.2 requires >=3.10, so no supported interpreter loses support.
Both new tests fail on the previous pins and pass on these.
* fix(passthrough): stream non-sse passthrough responses instead of buffering in memory
Non-SSE passthrough responses were fully read into proxy memory (content = await response.aread()) before the first byte reached the client. For large non-JSON bodies such as Anthropic batch results jsonl files this ballooned proxy RSS to a multiple of the file size and produced near-total TTFB dead air, letting intermediaries kill the silent connection and truncate the download.
The upstream request is now sent with httpx stream semantics and the buffering decision is made from the response headers: application/json (and +json) bodies plus upstream errors keep the buffered behavior since spend logging, guardrails and managed-id rewriting inspect them, while every other 2xx body is relayed as a StreamingResponse that iterates upstream bytes without accumulating them, preserving status code and headers (including x-litellm-*) and firing the success-handler logging with response_body=None once the stream completes.
* fix(passthrough): log client disconnects mid-stream and derive test client cache key from production code
* test(passthrough): intercept AsyncClient.send in legacy passthrough tests and assert final wire params
* test(passthrough): fail with a clear assert when the passthrough client cache scan misses
* fix(main): stop per-request custom pricing from clobbering shared model_cost pricing
A request routed through a wildcard deployment with explicit zero pricing
(e.g. openai/* with input_cost_per_token: 0) registered that pricing on the
shared {provider}/{model} key in litellm.model_cost, so sibling deployments
relying on built-in pricing logged $0 until process restart (LIT-3991).
Request-time registration in completion()/embedding() now mirrors the
router-startup isolation: router-originated requests register full pricing
under the deployment's unique model id only, while the shared backend key
receives the entry with custom pricing fields stripped. Direct SDK calls
without a router deployment id keep the legacy shared-key registration.
The stripping logic is shared via
CustomPricingLiteLLMParams.strip_custom_pricing_fields and reused by
Router._create_deployment and Router.add_deployment.
* test: update legacy tests that asserted per-request pricing leaking into shared model_cost
test_router_fallbacks_with_custom_model_costs asserted the shared
claude-sonnet-4-5-20250929 entry ends up with the deployment's 30/60
pricing, which is exactly the cross-deployment leak this PR removes; it
now asserts the shared key keeps the built-in pricing, matching the
test's stated goal.
test_cost_calc.py::test_run computed streaming cost via
completion_cost(response), which only matched the non-stream cost while
the shared gpt-3.5-turbo entry was poisoned with the per-request
2/token pricing; it now passes the request's custom pricing explicitly
via custom_cost_per_token.
* fix(bedrock): drop strict/additionalProperties from toolSpec for Claude Sonnet 4
Claude Sonnet 4 on Bedrock Converse rejects toolSpec.strict and
additionalProperties the same way Opus 4.7/4.8 do. Add
bedrock_converse_supports_strict_tools: false to all Sonnet 4 regional
variants so those fields are suppressed before the request is sent.

* test(bedrock): assert additionalProperties dropped for strict-unsupported models
Rename the regression test to reflect Opus 4.7/4.8 and Sonnet 4 coverage,
and assert both strict and additionalProperties are stripped from toolSpec.
