Both are lock-only moves. pypdf stays inside the existing
>=6.12.0,<7.0 constraint and pyasn1 is transitive, so pyproject.toml
is unchanged.
pypdf 6.13.3 carries CVE-2026-59935 / 59936 / 59937 / 59938, resolved
across 6.14.0 through 6.14.2. pyasn1 0.6.3 carries CVE-2026-59884 /
59885 / 59886, resolved in 0.6.4. All seven are resource-exhaustion
issues reachable through parsing untrusted input; pypdf is used for
page text extraction in the RAG ingestion file parser.
Scanning the lock before and after with CPE matching enabled takes the
count for these two packages from seven to zero.
CodSpeed benchmarks the SDK with no IO, so it can't catch regressions that
only appear under real concurrent load through the full proxy stack (auth,
routing, logging, spend, Postgres, Redis). This adds a Locust load test under
tests/e2e/load that drives concurrent POST /chat/completions traffic against a
mock deployment (litellm_params.mock_response), so the measured throughput
reflects proxy overhead rather than a provider's latency, and asserts an
aggregate RPS SLO with a failure-ratio guard. The test is marked load and the
parent conftest sorts load-marked items last so it never perturbs
latency-sensitive suites. Covers reliability.perf.throughput.under_slo.
Remove the python_version < '3.14' environment markers from redisvl,
pypdf, and openapi-core now that all three install and import cleanly
on 3.14. The relock is marker-only: no package version changed for any
Python branch, and the locked versions (redisvl 0.4.1, pypdf 6.13.3,
openapi-core 0.22.0) now serve 3.14 as well. semantic-router and
aurelio-sdk stay gated because every published release caps
python_requires below 3.14
* feat(cli): add `lite up`/`lite down` to ambiently route Claude Code through the proxy
Patches ~/.claude/settings.json in place (env.ANTHROPIC_BASE_URL + apiKeyHelper
via `lite auth print-token`) so any `claude` session started afterward, from
any terminal, routes through the local LiteLLM proxy with no wrapper command
needed, unlike the existing `lite claude` subprocess-exec approach. Backs up
the original file first and restores it on Ctrl-C/SIGTERM, or via `lite down`
after an unclean exit. Cursor is not supported: no equivalent file-based config
to patch.
* feat(cli): add lite autoroute to QA complexity-based auto-routing against a real proxy (#33249)
* feat(cli): add lite autoroute to QA complexity-based auto-routing against a real proxy
Lets a customer try litellm's complexity_router against models they already
have on their existing, unmodified production proxy, with no config.yaml
edits and no new infra. lite autoroute configure discovers accessible
models via /model_group/info and walks through tier assignment (plus
optional LLM classifier / semantic matching / adaptive selection); every
referenced model becomes its own litellm_proxy/<name> deployment forwarding
back to the real proxy with the real key, so every actual call, routed
completions, classifier calls, embedding calls, still lands on their real
proxy. lite autoroute up launches that generated config as an ephemeral
local proxy, patches ~/.claude/settings.json to point Claude Code at it, and
streams routing decisions live; Ctrl-C/SIGTERM (or lite autoroute down
after an unclean exit) restores everything.
Also adds lite model-groups list (a thin CLI wrapper over the existing
ModelGroupsManagementClient), and generalizes up.py's settings-backup/restore
helpers to take explicit paths so this feature can reuse them instead of
duplicating the logic.
Depends on litellm_lite_up_down (#33231) for that generalization.
* feat(cli): allow multiple models per autoroute tier
complexity_router already supports a pool of models per tier (randomly
picked per request; adaptive mode specifically needs a pool to choose
within), but the configure wizard only ever let you assign one. Tiers are
now a tuple of model names; the wizard prompt accepts comma-separated
indices to pick more than one per tier.
* feat(cli): fuzzy model picker and auto-route Claude Code to autorouter
Numbered-index selection didn't scale past a handful of models, so switch
the tier picker to InquirerPy's fzf-style fuzzy search. Also set
ANTHROPIC_DEFAULT_{SONNET,HAIKU,OPUS}_MODEL to "autorouter" in Claude
Code's settings, since Router resolves auto-router deployments by literal
model name with no wildcard support, so a "*" catch-all model_name would
never match real traffic.
* feat(cli): allow installing lite CLI from source via LITELLM_CLI_REF
Lets testers try an unreleased branch's CLI changes with the same
curl-piped installer, instead of waiting for a PyPI release.
* fix(ci): modernize type hints to clear ruff strict-rule budget
* fix(ci): bump httplib2 and setuptools to patched versions
Clears osv-scan findings for PYSEC-2026-3444 and PYSEC-2026-3447.
* fix(cli): write autoroute's secret-bearing files with mode 0600
commands.py wrote config.yaml (embeds the real proxy key) and Claude
Code's settings.json (embeds the ephemeral proxy's master key) with
plain open(), landing at the umask-derived default (commonly 0644)
until a later chmod call caught up. That window, and the missed case
where settings.json already exists (chmod never ran at all there),
left a credential-bearing file readable by another local account.
secure_create() fixes the mode via fchmod on the fd before any
content is written, covering both the brand-new-file and
already-exists cases, and commands.py/wizard.py now route their
sensitive writes through it.
* docs(cli): warn that a stale Claude Code session can leak to a squatted port
lite autoroute up's master key is embedded statically (unlike lite up's
apiKeyHelper, resolved per request), so a Claude Code session still
running after teardown keeps sending it, along with prompt content, to
a now-unbound loopback port that another local account can bind. This
is the same one-time-patch tradeoff lite up already accepts, just with
a static secret instead of a re-resolved one -- document it in the
README's Caveats section and surface it in the teardown message itself.
* fix(cli): address greptile review feedback on autoroute PR
- terminate the ephemeral proxy child process when its health check
fails, instead of leaking an orphaned, unrecoverable process bound
to the port
- replace bare assert isinstance checks (no-ops under python -O) with
click.ClickException in the model-groups list and configure wizard
code paths
- close launch_proxy's log file handle once the child process has
inherited its fd, instead of leaking it
- add build_generated_proxy_config to config.py's __all__
* fix(cli): close TOCTOU window in lite up's settings backup write
write_backup wrote the backup (which can embed the original
apiKeyHelper/settings content) with plain open() + a chmod call after
the fact -- the same permissive-until-corrected window already fixed
for autoroute's config.yaml and Claude settings writes, and missed
entirely when the backup file already exists with broader permissions.
Moves secure_create (atomic-enough 0600 via fchmod before any content
is written) to up.py, the module both lite up and lite autoroute
share, and has autoroute/process.py import it from there instead of
keeping its own copy.
* fix(cli): refuse autoroute up when a stale backup exists from a crash
The pid-record check only catches a still-live duplicate process; a
SIGKILL'd `up` leaves no live pid but does leave AUTOROUTE_BACKUP_PATH
behind. Without this guard, a fresh `up` overwrote that backup with
the currently-patched Claude settings instead of the true originals,
so `down`/Ctrl-C would restore the wrong content permanently. up.py's
`lite up` already guards the analogous case; mirror it here.
* fix(cli): bind the ephemeral autoroute proxy to loopback only
proxy_cli.py defaults --host to 0.0.0.0 when not passed explicitly.
launch_proxy never passed it, so the ephemeral proxy -- despite every
base_url in this module being built from 127.0.0.1 -- was actually
reachable from other hosts on the network, including its
unauthenticated-until-config-lands routes before the master key is
wired in.
* docs(cli): show curl install for the autoroute QA flow
Points readers at scripts/install-cli.sh's curl one-liner instead of
assuming uv/pip is already set up, and documents the LITELLM_CLI_REF
override for trying an unreleased branch or commit.
* fix(cli): surface a clean error on an empty or corrupt autoroute config
A configure run killed between secure_create's O_TRUNC and the write
completing leaves an empty config.yaml on disk. The next up read that
via yaml.safe_load (None) into the generated-config TypeAdapter
uncaught, surfacing a raw pydantic.ValidationError instead of pointing
the user back at `lite autoroute configure`.
* fix(cli): bind lite up's apiKeyHelper to the proxy it was started against
_ensure_fresh_login only checked token freshness, not which proxy the
cached token belonged to, and resolve_api_key_helper built a bare
`lite auth print-token` command with no --base-url. A user logged into
proxy A who ran `up --base-url proxy-b` (or LITELLM_PROXY_URL=proxy-b)
would silently get proxy A's real token wired into Claude Code's
apiKeyHelper; since apiKeyHelper is invoked bare, print-token's
existing origin check never engaged, so proxy B -- attacker-controlled
or not -- received every subsequent request's Authorization header
carrying proxy A's credential.
_ensure_fresh_login now requires the cached token's base_url to match
before treating it as usable, forcing a fresh login for the selected
proxy otherwise. resolve_api_key_helper now takes that base_url and
threads it through as an explicit --base-url, so print-token's
existing (but previously unreachable in the apiKeyHelper flow)
base_url_explicit check actually enforces the match at request time
too.
* fix(cli): surface clean errors instead of raw tracebacks in lite up/down
load_json_or_empty and read_backup both delegate to pydantic's
validate_json, which raises ValidationError on invalid JSON or a
non-object root -- neither up() nor down() caught it, so a corrupt
settings or backup file surfaced an unformatted Python traceback
instead of a clean CLI error. Both now convert to UpError, and down()
(previously uncaught entirely) and up()'s teardown path now handle it.
restore_claude_settings also gained a parent.mkdir guard before
rewriting CLAUDE_SETTINGS_PATH: if ~/.claude/ was removed while `lite
up` was running, the restore would crash before deleting the backup
file, permanently stranding it and breaking every future `lite down`.
* docs(cli): call out env-var auth for autoroute commands
* fix(cli): clean up leaked proxy and surface clean errors in autoroute
Three related gaps, all following an UpError getting raised somewhere
that wasn't catching it yet:
- up() left the just-launched ephemeral proxy running with no pid
record if load_json_or_empty/write_backup/secure_create raised after
the health check passed, mirroring the existing ProcessLaunchError
cleanup for the health-check-failure branch.
- _teardown() didn't catch restore_claude_settings raising UpError
(e.g. a corrupt backup at stop time), which would otherwise escape
to Click as an unhandled error in the normal-exit path, or print
"Error in atexit" in the atexit path. up.py's own _restore_once
handles the identical case the same way.
- read_pid_record let a corrupt PID file surface a raw
pydantic.ValidationError instead of a clean message, and did so in
down(), the command specifically meant for crash recovery. down()
now clears an unreadable pid record and continues cleanup instead of
aborting, since a corrupt pid file must never block the one command
meant to recover from exactly this kind of crash.
* docs(cli): warn against running lite up and lite autoroute up together
A single ddtrace constraint now covers every supported Python version, so this collapses the version split introduced in #33438. Also aligns the build_from_pip image pin and updates the type-only Tracer import to its current module path
* build: drop requires-python upper cap so Python 3.14 resolves to current releases
The <3.14 cap made pip on Python 3.14 fall back to litellm 1.83.7, a
pre-April release whose old auth flow fails with 400s. The cap was added
in d9a460277a because deps lacked 3.14 wheels and uv could not resolve
the 3.14 split; both are fixed now via the existing python_version
markers plus a ddtrace version split (2.x has no cp314 wheels, 3.16+
does). Verified on 3.14.5: uv sync --all-extras installs, litellm and
proxy_server import (rust bridge falls back to pure python), real
provider calls succeed sync/async/streaming, and the core-utils test
suite passes.
* build: cap requires-python at <3.15 and keep ddtrace on one major per python band
Reviewer preference to bound the supported window at the newest tested
minor rather than leaving it open-ended, and Greptile flagged the
ddtrace 3.14+ range spanning two majors; every ddtrace 4.x ships cp314
wheels so the band is now >=4.0,<5.0, matching the single-major
convention of the 2.x band.
Raise the constraint floors for two transitive dependencies so resolution moves them to their latest maintenance releases: httplib2 0.31.2 -> 0.32.0 and setuptools 82.0.1 -> 83.0.0. Both are pulled in only by optional integrations (Google API client, grpc tooling, lunary observability, the nvidia-riva extra), all lower-bound only, so the floors stay inside every requirer's allowed range and a default install is unaffected
* feat(a2a): support a2a-sdk 1.x proxy routing for 0.3 and 1.0 agents
Bump a2a-sdk to 1.x and wire send/stream through compat conversions so the proxy accepts A2A 1.0 JSON-RPC while preserving 0.3 wire clients.

* fix(a2a): suppress reportArgumentType for SDK compat types and fix streaming trace ID
- Add pyright: ignore[reportArgumentType] to SendMessageSuccessResponse id= and
result= args in _send_message, and SendStreamingMessageResponse root= in
_stream_messages, where a2a-sdk compat types diverge from basedpyright's
inferred signature, reducing the reportArgumentType count back within budget.
- Fix streaming trace ID in astream_a2a_message to use str(request.id) when
available instead of always generating a new uuid4(), restoring JSON-RPC
request-ID correlation for observability.

* fix(a2a): fix 2 reportArgumentType errors without suppression
- main.py: narrow logging_obj from object|None to Optional[Logging] via
isinstance check before A2AStreamingIterator call, fixing the
"Logging | object" argument type mismatch at line 699.
- a2a_endpoints.py: extract response_dict with explicit isinstance(dict)
guard before passing to normalize_jsonrpc_response, fixing the
"LLMResponseTypes | dict[str, Any]" type mismatch at line 835.
- Remove spurious pyright: ignore comments added in previous commits that
were not suppressing the actual errors.

* fix(a2a): rewrite upstream URL for 1.0 agent cards in getAuthenticatedExtendedCard
1.0 upstream agent cards store the endpoint URL in supportedInterfaces[0].url
rather than a top-level url field. The previous guard only rewrote url when
it existed at the top level, so after normalize_agent_card lowered a 1.0 card
to 0.3 the upstream internal address leaked into the url field of the 0.3
response.
Fix: rewrite both url and supportedInterfaces[0].url to the proxy address
before calling normalize_agent_card, ensuring the upstream address is never
visible to downstream clients regardless of the upstream card's wire format.

* fix: extend _served_version to all PascalCase methods; add direct httpx-client isolation proof
- _served_version now checks `_PASCAL_TO_WIRE` membership instead of two
hardcoded names, so GetTask/CancelTask/etc. are promoted to 1.0 wire format
alongside SendMessage — prevents mixed wire formats mid-session
- test_create_a2a_client_uses_fresh_httpx_client now asserts
a2a_client_a._litellm_httpx_client is not a2a_client_b._litellm_httpx_client
(direct proof that header bleed cannot occur), in addition to the cache-key
inequality check

* fix: id:0 silently dropped in version_convert; explicit continue in stream retry
- version_convert.py: replace `request_id or ""` with
`str(request_id) if request_id is not None else ""` in both
_send_result_to and _stream_result_to; id=0 is valid JSON-RPC and
must not be coerced to "" which breaks response correlation
- main.py: add explicit `continue` after the A2ALocalhostURLError retry
in _execute_a2a_stream_with_retry so the control flow (retry → next
iteration → stream_succeeded guard) is unambiguous

* fix(a2a): ignore unknown fields in message/send proto fallback

Co-authored-by: Cursor <cursoragent@cursor.com>
* refactor(a2a): drop private SDK symbol in tasks/list status lowering
_lower_list_tasks_params imported _CORE_TO_COMPAT_TASK_STATE, a private
a2a-sdk symbol that could disappear on a patch release and silently break
status-filter lowering. Derive the 0.3 wire string from the public
protobuf enum name instead (TASK_STATE_<NAME> maps to the 0.3 value once
the prefix is dropped and underscores become dashes) and validate the
result against the 0.3 TaskState enum's own values via a fully-typed pure
helper. Behavior is unchanged for every state; unspecified or unrecognized
states still drop the filter. Adds parametrized regression tests covering
dashed wire values (input-required, auth-required) and the unspecified drop.
* fix(a2a): drop redundant push-notification envelope key; unify MessageToDict import
_flatten_create_push_notification_params used `config or pushNotificationConfig`,
which short-circuits so a co-present pushNotificationConfig key was never popped and
leaked into the flattened params. Pop both keys unconditionally and prefer config
when present. Adds a regression test on the helper that fails on the old leak.
Also import MessageToDict from a2a.compat.v0_3.conversions in _lower_list_tasks_params
to match every other conversion helper in the module instead of pulling it straight
from google.protobuf.json_format.
* fix(a2a): reject invalid message/stream params early with -32602
_handle_stream_message built MessageSendParams lazily inside the
stream_response() generator, so malformed 1.0 params surfaced as a generic
-32603 after the 200 status line was already committed. The non-streaming
path validates up front and returns -32602 (Invalid params). Validate
eagerly before returning the StreamingResponse and emit -32602 on failure
so both paths reject malformed params identically. Adds a regression test
asserting the streamed error code is -32602.
* fix(a2a): raise clear error when non-streaming send ends on an update event
_send_message fed the SDK iterator's last event straight into
SendMessageSuccessResponse, whose result only accepts Message or Task. A
non-standard upstream whose final event is a TaskStatusUpdateEvent or
TaskArtifactUpdateEvent made the response construction raise an opaque
pydantic ValidationError. Guard the converted result and raise a clear
RuntimeError instead, consistent with the no-response guard above it.
Adds regression tests for the Message happy path and the update-event
rejection via an injected fake client.
* test(a2a): lock in clean merged agent-card URL without PROXY_BASE_URL
Regression coverage proving _build_merged_agent_card produces no double
slash in supportedInterfaces[0].url when PROXY_BASE_URL is unset and
request.base_url carries a trailing slash. get_custom_url routes through
join_paths, which rstrips the base, so the f-string join stays clean.
* style(a2a): modernize type annotations to satisfy strict ruff budget
After merging the black->ruff-format migration from base, the A2A files
owned by this PR still used Optional[X]/quoted annotations that pushed
UP037/UP045 over their lowered ceilings. Convert to X | None, drop the
now-unnecessary quoted local annotation in _send_message, and remove the
imports left unused by the rewrite. Type semantics are unchanged.
* style(a2a): type a2a_endpoints dict params as dict[str, Any]
The merge with the formatter-migration baseline tightened the
reportUnknownArgumentType ceiling; bare dict annotations made every value
Unknown and pushed the codebase total over cap. Annotate the JSON-RPC
params, body, metadata, and litellm_params dicts as dict[str, Any] so
their values are typed, dropping the unknown-argument count back under the
ceiling. No behavior change.
* fix(a2a): guard localhost retry against a missing agent card
handle_a2a_localhost_retry rewrote the card URL and called create_client
with whatever agent_card it received. The caller resolves the card from
the SDK client (Optional), so a None card reached set_agent_card_url and
create_client, surfacing an opaque SDK error instead of a clear one. Add
an early RuntimeError guard mirroring the httpx-client check, drop the now
always-true card None-check on the stash line, and cover it with a
regression test.
* style(a2a): disable reportUnknownArgumentType in a2a-sdk boundary modules
The lint env type-checks without the optional a2a-sdk/protobuf installed, so
every call into the protobuf-generated compat conversions counts as an
Unknown-typed argument and the new A2A code pushed the codebase
reportUnknownArgumentType total over its ceiling. These three modules are
the A2A SDK boundary; turn the rule off file-wide with a documented reason
instead of scattering dozens of per-line ignores across every SDK call.
* fix(a2a): tolerate unknown fields when lowering 1.0->0.3; align streaming trace id
Two issues greptile flagged:
version_convert: the 1.0->0.3 lowering paths (_send_result_to, _task_to,
_stream_result_to) called ParseDict without ignore_unknown_fields=True, so a
1.0 upstream response carrying vendor extensions raised and best-effort fell
back to passing the un-lowered 1.0 shape to a 0.3 client. Set the flag to match
the agent-card path and every inbound path; unknown fields are now dropped and
the result is correctly lowered.
main.py: asend_message_streaming derived X-LiteLLM-Trace-Id from the JSON-RPC
request id, unlike asend_message which uses the logging object's
litellm_trace_id. Prefer the logging trace id (then request id, then a uuid) so
streamed and non-streamed calls correlate under the same trace.
Adds regression tests for both, including the stream-event lowering path.
* style(a2a): apply ruff format to a2a protocol and proxy modules

Bumps the 12 packages osv-scanner flags on litellm_internal_staging, taking
the scan from 24 known vulnerabilities to zero. vcrpy goes to 8.2.1 first so
aiohttp can move to 3.14.1 (vcrpy <= 8.1.1 cannot import aiohttp 3.14), then
the two aiohttp ignore entries are dropped from osv-scanner.toml. The
langchain stack moves together since langchain 1.3.9 requires langgraph 1.2.x.
Runtime deps cryptography (48.0.1), starlette (1.3.1), python-multipart
(0.0.32), pydantic-settings (2.14.2) and pypdf (6.13.3) are bumped via relock,
and the dashboard's js-yaml, ws and form-data overrides are bumped too.
Also removes the paths filter on the OSV workflow so it runs on every PR
rather than only when a lockfile changes, which is why it never showed up on
recent code-only PRs
* feat(mcp): scaffold outbound_credentials package with typed Result
PR1 of the MCP v2 outbound-credential migration. Adds the
litellm/proxy/_experimental/mcp_server/outbound_credentials/ subpackage with a
hand-rolled Ok | Error Result union (pure stdlib + typing_extensions, no new
dependency) and its package surface. Nothing imports this on a live request path
yet, so production behavior is unchanged; later PRs add the typed config
vocabulary, the resolve_credentials dispatch, and the v1 graft.
* feat(mcp): add outbound_credentials typed vocabulary (#31049)
PR2 of the MCP v2 outbound-credential migration, stacked on the result.py
scaffolding. Adds types.py (the AuthConfig discriminated union over seven frozen
per-mode configs, CredError as an expression @tagged_union, Subject, ServerSpec,
and the parse_auth_spec_kind boundary parser) and httpx_auth.py (NoOpAuth,
StaticHeaderAuth). Pulls in expression>=5.6.0,<6.0 on the proxy extra for the
tagged union. Construction-time tests prove illegal mode/field combinations are
rejected. Nothing is wired onto a request path yet; the resolver lands next.
* ci: drop redundant mypy type-check gate, standardize on basedpyright
Type checking ran both mypy (via the pydantic.mypy plugin) and basedpyright.
pydantic v2 emits dataclass_transform, so basedpyright understands models
natively with no plugin, and its gated rules already cover what the mypy pass
caught (no-untyped-def, no-any-return, valid-type, import-not-found all map to
basedpyright equivalents). Running both meant two checkers, two budgets, and a
plugin only mypy could load.
This removes the mypy type-check gate: the lint-mypy/lint-mypy-budget-update
Makefile targets, the CI MyPy step, mypy-code-budget.json, the budget-ratchet
entry, and the vestigial [tool.mypy] pydantic plugin block (the gating pass used
litellm/mypy.ini, which never loaded the plugin). type_check_gate.py is
specialized to basedpyright since the mypy parsing path is now unused.
mypy stays a dev dependency because the Any-discipline gate
(scripts/check_any_discipline.py) imports it as a library to detect Any-typed
values; it is no longer run as a type checker.
* ci: remove the Any-discipline gate, rely on basedpyright's reportAny
The Any-discipline gate (scripts/check_any_discipline.py) was the last consumer
of mypy: it imported mypy as a library to detect values whose inferred type
contains Any, gated per-file against any-discipline-budget.json. basedpyright
already reports the same class of finding through reportAny/reportExplicitAny,
which are gated tree-wide in basedpyright-code-budget.json, so the separate gate
(and the mypy dependency behind it) is redundant.
Removes the gate end to end: check_any_discipline.py and its test, the
any-discipline CI job, the lint-any/lint-any-budget-update Makefile targets,
any-discipline-budget.json, litellm/mypy.ini, the .mypy_cache_any references,
and mypy from the dev dependencies. budget_ratchet_check.py drops the
any-discipline entry and the now-unused zero-floor mechanism (rewritten as a
comprehension). check_type_discipline.py drops the any-ok suppression token,
since # any-ok suppressed only the deleted gate; the 134 now-orphaned
# any-ok comments across 14 files are stripped (they never affected
basedpyright, which uses # pyright: ignore).
uv.lock is intentionally left untouched: uv still considers it consistent with
the mypy-removed pyproject (uv lock --check and uv sync --frozen both pass), and
a relock bumps 30+ unrelated packages because of the moving exclude-newer window.
A future intentional relock will prune the now-unreferenced mypy entry.
* build: relock to drop mypy from uv.lock
CI's uv 0.10.9 honors the repo's exclude-newer window and correctly flags the
lockfile as out of sync once mypy leaves pyproject; my earlier local uv 0.8.17
could not parse exclude-newer and silently passed --check. Relocking with the
pinned CI version removes only mypy and its transitive librt, with no other
version changes.
* ci: enable ruff preview rules under the budgeted strict gate
Turn on ruff preview in the strict-budget lane (ruff-strict.toml) only,
leaving the clean gate (ruff.toml) untouched so make lint-ruff stays at
zero. Enumerate the 118 firing codes explicitly with
explicit-preview-rules so the gate is deterministic and stable across
ruff upgrades rather than depending on preview auto-selecting the broad
catalog.
Grandfather the existing 58438 violations into ruff-strict-budget.json
as per-rule baselines with headroom, so only net-new violations fail CI.
The existing ten rules keep their hand-tuned slack; the new rules get
slack 10 when the baseline is 50 or more and 3 otherwise.
* ci: add ANN return-type rules to the budgeted strict gate
Add ANN201/202/204/205/206 (missing return annotations) to the strict
lane and grandfather the existing counts into ruff-strict-budget.json so
the codebase ratchets toward explicit return types without breaking CI.
* ci: add mypy (disallow_untyped_defs) and basedpyright strict gates with baselines
Add two type-check gates, each grandfathering the current tree so only
net-new violations fail CI, matching the ruff strict-budget ratchet.
mypy gains disallow_untyped_defs in litellm/mypy.ini (the config the CI
invocation actually reads; the root [tool.mypy] is not picked up from the
litellm/ working dir). The 4885 existing missing-annotation errors are
captured in litellm/.mypy-baseline.txt and the run is piped through
mypy-baseline filter so new untyped defs are rejected.
basedpyright runs in strict mode over litellm/, with
enableTypeIgnoreComments disabled so it only honors '# pyright: ignore'
and never polices mypy's '# type: ignore'. The existing strict diagnostics
are grandfathered into .basedpyright/baseline.json.
Both tools are pinned in the dev group and uv.lock; the lint workflow and
Makefile run them filtered through their baselines, with
lint-mypy-baseline-update and lint-basedpyright-baseline-update to ratchet.
* ci: raise lint job timeout to 15m for the basedpyright strict pass
* ci: pin pythonVersion 3.12 and regenerate baselines against merged base
Merge litellm_internal_staging so the baselines cover code the CI merge
includes (e.g. the cisco_ai_defense guardrail), which otherwise tripped
the mypy gate with 3 ungrandfathered no-untyped-def errors. Pin
pythonVersion 3.12 in pyrightconfig so basedpyright's strict analysis is
reproducible across interpreter versions (CI runs 3.12).
* ci: regenerate basedpyright baseline against the frozen lint env
The previous baseline was generated with optional provider deps (azure,
google, anthropic, mcp, numpydoc, google-genai) installed locally, so CI's
dev-only env surfaced ~3500 reportUnknown*/reportMissingTypeStubs errors
not in the baseline. Regenerate after uv sync --frozen so the baseline
reflects the same dependency set the lint job sees.
* ci: regenerate basedpyright baseline on python 3.12 frozen env
The prior baseline still carried proxy-dev packages (e.g. prisma) that the
lint job's dev-only, python 3.12 env lacks, leaving 2 unresolved-import
errors ungrandfathered. Regenerate in a python 3.12 venv synced to the
frozen lock with default groups only, so the baseline matches exactly what
CI sees.
* ci: replace type-check baselines with per-file count budgets
The mypy and basedpyright baselines were position-sensitive (and the
basedpyright one was a 27MB file), so ordinary line shifts churned them.
Replace both with a per-file count gate: scripts/type_check_gate.py reduces
each tool's output to errors-per-file and checks it against a committed
{file: max} budget, ignoring line and column numbers. A file fails only
when it gains more errors than its ceiling; debt can't be shuffled between
files because each file has its own cap and new files default to zero.
Budgets (mypy-file-budget.json 48K, basedpyright-file-budget.json 96K) are
generated in the python 3.12 frozen lint env so they match CI. Drops the
mypy-baseline dependency; basedpyright runs without its native baseline.
ratchet via make lint-mypy-budget-update / lint-basedpyright-budget-update.
* ci: add a small per-file slack to the type-check gate
Allow each file to drift PER_FILE_SLACK (5) errors past its recorded count
before failing, so a basedpyright inference ripple in an unrelated file
doesn't break the build over a couple of errors. Budgets still record exact
counts; the tolerance is applied at check time.
* ci: move type-check slack into the budget json and trim lint timeout
Make slack declarative: the budget is now {"slack": N, "files": {path: count}}
so the tolerance is tuned in JSON without editing the script, mirroring how
ruff-strict-budget.json carries its slack. --update preserves the existing
slack. Also drop the lint job timeout from 15m to 10m; the mypy and
basedpyright passes add ~2m, leaving the job around 4-5m, so 10m is a
comfortable margin.
* ci: collapse fully-adopted ruff categories and drop inert preview flag
ANN (all nine non-removed rules) and BLE (its only rule) were spelled out
code-by-code; replace each with its category selector, which is exactly
equivalent in 0.15.3 (the removed ANN101/ANN102 are skipped by a category
selector and error when named explicitly). explicit-preview-rules was inert:
every selected rule is stable and nothing is selected by category, so the flag
had nothing to gate. Verified the strict-rule counts are identical before and
after (62379 each, zero per-rule drift), so no budget change.
* ci: drop redundant pyright dev dependency
Nothing invokes bare pyright in the Makefile, the linting workflow, or
scripts; the basedpyright gate added on this branch is the only type
checker that runs. basedpyright is a superset fork that reads the same
pyrightconfig.json and honors the same "# pyright: ignore" comments, so
pyright==1.1.408 in the ci group was dead weight. Regenerated uv.lock
under the same exclude-newer cutoff so the only change is removing
pyright and its package stanza
* ci: un-weaken mypy and error on Any in basedpyright
mypy: enable warn_return_any, drop the valid-type silencer, and stop globally ignoring missing first-party imports via [mypy-litellm.*] ignore_missing_imports = False, which surfaced eight real broken litellm.* imports the blanket ignore was hiding; third-party imports stay ignored. The per-file budget moves 4888 -> 5799 (902 no-any-return, 1 valid-type, 8 import-not-found), all grandfathered so only net-new errors fail and the ceilings ratchet down
basedpyright: error on reportExplicitAny and reportAny. The per-file budget moves 117033 -> 148946 (6931 explicit-Any, 24954 Any-typed expressions), grandfathered the same way
* ci: add Any-discipline gate on changed lines under litellm/
Add scripts/check_any_discipline.py, a type-aware gate that fails when a
changed line holds a value typed Any -- including the X | Any unions that
mypy --strict / basedpyright accept (e.g. re.Match.group() -> str | Any,
json.loads() -> Any, bare dict -> dict[Any, Any]).
It reuses the repo's mypyc-compiled mypy 1.19 via a custom generic AST
walker (mypyc precludes subclassing TraverserVisitor), loads litellm/mypy.ini
for parity with lint-mypy, and uses a dedicated incremental cache
(.mypy_cache_any) with mtime+hash invalidation to force re-checks. Scope is
changed-lines-only so editing a legacy file never forces cleaning its
existing Any debt; suppress a genuine typed/untyped boundary with
# any-ok: <reason> (ANY002 requires the reason).
Wire it into the Makefile (lint-any, lint, lint-dev), a parallel
any-discipline CI job with its own actions/cache, .gitignore, and the
CLAUDE.md / CONTRIBUTING.md docs.
* ci: move Any-gate codes into the shared LIT namespace
Renumber the Any-discipline checker into the LIT*** scheme owned by
scripts/check_type_discipline.py (PR #30500) so the two checkers share one
rule namespace and suppression convention:
ANY001 -> LIT002 (Any-typed value; LIT002 was the retired/free slot)
ANY002 -> LIT005 (any-ok without a reason; the shared suppression-reason code)
ANY000 -> LIT000 (setup/build/read error; the shared error code)
Messages and behavior are unchanged; LIT005's text already matches the
"<token> requires a reason" shape used for cast-ok/guard-ok.
* ci: gate mypy and basedpyright per error rule, not per file
Switch the mypy/basedpyright budget gate from per-file error counts to
per-rule-code totals, mirroring the {rule: {baseline, slack}} shape of
ruff-strict-budget.json. A rule fails when its codebase-wide error count
exceeds baseline + slack, so violations are tracked by category rather
than by file location.
scripts/type_check_gate.py now parses mypy from its text output (trailing
[code]) and basedpyright from --outputjson (the JSON `rule` field), since
basedpyright's wrapped text diagnostics mis-attribute the rule on
continuation lines. Replace the *-file-budget.json files with freshly
captured *-code-budget.json baselines and update the Makefile, CI, and
CLAUDE.md accordingly.
* docs: prefer Pydantic validation over any-ok suppression
Point the Any-discipline guidance at validating Any with Pydantic (a model
or TypeAdapter that returns a typed value or raises) and frame
# any-ok as a last resort that should ideally never be used.
* chore: remove extraneous comment
* chore: make the CLAUDE.md more concise
* chore: clean up bloated CONTRIBUTING.md additions
* chore: make Makefile more concise
* ci: add the lint-budget-update target CLAUDE.md references
CLAUDE.md tells contributors to run make lint-budget-update, but the
target was never defined. Add it as an aggregate that re-captures the
ruff, mypy, and basedpyright budgets in one shot.
* ci: recapture mypy and basedpyright budgets in the lint env
The per-rule baselines were captured in a richer dependency env than the
CI lint job's uv sync --frozen, so CI resolved fewer types and reported
more errors than the budgets allowed (no-any-return 902 over cap 900, plus
several basedpyright reportUnknown* rules). Regenerate both in the frozen
env so they grandfather the true CI debt: mypy 5786 -> 5799 (no-any-return
890 -> 902, valid-type 1 restored), basedpyright 146213 -> 148942.
* ci: check out PR head sha in lint and any-discipline jobs
The default pull_request checkout uses refs/pull/N/merge, which folds the
latest base commits into HEAD. The diff-based gates (ruff delta, Any
discipline) then diff against the event's older base.sha and blame base's
own new commits on this branch; staging's otel-v2 and streaming changes
(#30326, #30485) tripped the Any gate on files this branch never touched.
Checking out the PR head sha makes the gates diff the real branch tip
against base, and pins the tree the mypy/basedpyright budgets were captured
against so their counts stay deterministic as the base advances.
* ci(lint): renumber Any-typed-value rule LIT002 -> LIT009
Free up LIT002 for the sibling type-discipline gate (check_type_discipline.py,
#30500), which groups its mutable-collection family at LIT001 (annotation) and
LIT002 (construction). This gate's Any-typed-value rule moves to LIT009 so the
shared LIT namespace stays contiguous with no holes; LIT000 and LIT005 are
unchanged.
* style: rename lint-strict-budget -> lint-ruff-budget
* ci: harden type-check gates against silent passes (greptile review)
type_check_gate.py: refuse to certify a vacuous run. The CI pipe swallows
the tool's exit code ('tool || true'), so a crashed mypy/basedpyright that
emits nothing would parse to zero errors, breach no ceiling, and pass.
is_vacuous_run() now fails when nothing was parsed but the budget expects
errors. Also wrap basedpyright's json.loads in a JSONDecodeError handler
that prints the offending output instead of dumping a raw traceback.
check_any_discipline.py: ALL_LINES was None, which dict.get() also returns
for a path absent from the line map, so a path-normalisation mismatch could
let a violation on an unchanged file pass the scope filter. Make ALL_LINES a
distinct sentinel object so 'whole file' and 'path missing' are unambiguous.
Adds tests for all three.
* chore(deps): bump aiohttp to 3.14.1 and vitest to 3.2.6
Lockfile-only bump for aiohttp (3.13.5 -> 3.14.1, within the existing
pyproject constraint) and dashboard devDependency bumps for vitest,
@vitest/coverage-v8, @vitest/ui (3.2.4 -> 3.2.6) plus transitive
brace-expansion (5.0.5 -> 5.0.6). Clears the currently published
advisories flagged by osv.dev against uv.lock and the dashboard
lockfile. Verified: 154 custom_httpx unit tests and all 3943 dashboard
vitest tests pass; live proxy completion and streaming calls succeed on
the bumped venv
* chore(deps): raise aiohttp floor to 3.14.0
The lockfile bump alone only protects environments built from uv.lock.
Raising the pyproject floor extends the same minimum to package
consumers installing litellm from PyPI, and prevents a future lockfile
regeneration from resolving below 3.14.0
* Revert "chore(deps): raise aiohttp floor to 3.14.0"
This reverts commit d6c1c9dc0c.
* revert(deps): roll back aiohttp to 3.13.5
vcrpy is incompatible with aiohttp >= 3.14 (the aiohttp_stubs module
imports a symbol removed in 3.14) and the upstream fix is merged but
unreleased, so every cassette-based test suite fails on 3.14. Hold
aiohttp at 3.13.5 until a vcrpy release ships; the vitest and
brace-expansion bumps stay
* chore(deps): bump pypdf to 6.13.1 and tornado to 6.5.7
Lockfile-only bumps clearing the advisories published for both since
this branch was opened
* chore(deps): add regression guards for the bumped versions
Raise the pypdf floor to 6.12.0 (direct dependency, applies to package
consumers too) and add uv constraint-dependencies for the transitive
pins: tornado >= 6.5.6, and aiohttp held in [3.13.5, 3.14) so a lockfile
regeneration can neither fall back below the current version nor move
onto 3.14 while vcrpy is incompatible. Constraints live in [tool.uv]
and only affect this repo's resolution, not published metadata.
Verified: uv lock -P with each out-of-range version fails to resolve;
in-range resolutions unchanged (pypdf 6.13.1, tornado 6.5.7,
aiohttp 3.13.5)
* feat(cli): add `litellm-proxy run -- <agent>` to wrap coding agents through the proxy
Wraps Claude Code, Codex, OpenCode, and any other coding agent so all of its
LLM traffic routes through a LiteLLM proxy, with the agent-vault style of "just
works" DX: one `run -- <agent>` command, auto SSO login when interactive,
env-key "agent mode" for containers/CI, and a fail-fast key check against the
proxy so bad credentials error immediately instead of deep inside the agent.
The wrapped binary is detected by name to pick the right variables. Claude Code
gets ANTHROPIC_BASE_URL (the bare proxy root, so it appends /v1/messages) and
ANTHROPIC_AUTH_TOKEN, with any stray ANTHROPIC_API_KEY cleared so the proxy
token wins. Codex and OpenCode get OPENAI_BASE_URL (proxy + /v1) and
OPENAI_API_KEY. Unrecognized commands get both sets so they work either way.
`litellm-proxy claude-code` remains as a shortcut for `run -- claude`.
The core logic is split into dependency-injected helpers (agent_profile,
build_agent_env, verify_proxy_key, run_agent) so env wiring, the preflight, and
the launch handoff are unit-tested without monkeypatching, alongside CliRunner
tests for auth resolution, agent mode, and auto-login. Mutation-tested the env
profiles, preflight, and agent-mode branch to confirm the tests fail when the
behavior is broken.
https://claude.ai/code/session_0154VpLXW7mMvk5wfbgPRJa6
* Make each coding agent its own litellm-proxy command
Replace the `run -- <agent>` interface and the `claude-code` shortcut with
top-level commands generated per known agent, so launching is just
`litellm-proxy claude`, `litellm-proxy codex`, or `litellm-proxy opencode`,
with everything after the agent name forwarded straight to it. This drops the
ceremony of `run --` and cuts typing.
The `--model`/`--small-fast-model` wrapper flags are gone; pass the agent's
own model flag instead, or export the model env vars (the wrapper preserves
what you already have set), which keeps the surface minimal and avoids
intercepting flags the agent owns. Rename the module to agents.py to match.
* fix(cli): route `litellm-proxy codex` through the proxy via a custom provider
Codex ignores OPENAI_BASE_URL (it always dials api.openai.com over the
Responses WebSocket transport), so the OpenAI env profile alone left
`litellm-proxy codex` talking to OpenAI directly instead of the proxy. Point
Codex at the proxy with a custom provider passed as `-c` config overrides, and
force the HTTP/SSE Responses transport with supports_websockets=false since the
proxy does not speak the Responses WebSocket protocol. The provider reads its
key from OPENAI_API_KEY, which the agent env already exports.
The overrides are injected ahead of the user's args so they precede Codex's
subcommand. Claude Code and OpenCode are unaffected; they honor the exported
env vars. Adds regression tests for the per-agent launch args and the
injection ordering.

* Rename litellm-proxy CLI command to lite
The proxy management CLI was invoked as litellm-proxy, which is a lot to
type for an everyday command. Rename the console script entry point to
lite and update the in-CLI usage examples, help text, error messages and
docs to match.
* fix(sso): stop CLI auth success page from hanging on "Closing..."
The CLI opens the SSO success page with webbrowser.open, so the tab is
not script-opened and the browser refuses window.close(). The countdown
would end on "Closing..." and the tab would sit there forever.
Drop the countdown and just show "You can now close this window and
return to your terminal." from the start, while still attempting
window.close() once so the tab auto-closes in the rare case the browser
allows it. Add a regression test asserting the manual-close instruction
is always present and the misleading countdown/"Closing..." text is gone.
* fix(cli): reattach controlling terminal after SSO login, keep litellm-proxy alias
When the first `lite claude` has to log in via browser SSO, completing the login could
leave stdin detached from the terminal, so a TUI agent like Claude Code would start in
non-interactive mode and exit with "Input must be provided". The wrapper now reopens the
controlling terminal onto stdin just before handoff when the session started interactively;
piped or redirected input is detected up front and left alone, so agent-mode and
non-interactive use are unchanged.
Also keep the `litellm-proxy` console script as an alias for `lite` so existing scripts and
CI that invoke `litellm-proxy` keep working; both names map to the same CLI.
* feat(install): make the curl installer need only curl, not a pre-existing Python
The installer now lets uv provision a managed Python 3.13 when no suitable
interpreter is found, instead of aborting. The minimum is also bumped from
3.9 to 3.10 to match the package's requires-python (>=3.10), so a system
Python 3.9 is no longer selected only for uv tool install to reject it.
* feat(cli): add thin litellm[cli] install path (install-cli.sh + brew) for the lite CLI
On a developer laptop the `lite` CLI only needs `lite login` and running coding
agents through a proxy, but the sole install path was `litellm[proxy]`, which
drags in the whole server tree (fastapi, uvicorn, boto3, polars, cryptography,
litellm-enterprise). The CLI's heavy imports are all guarded, so it runs on the
base SDK plus just rich, pyyaml and requests.
Add a `cli` extra carrying exactly those three, a `scripts/install-cli.sh` curl
one-liner that installs `litellm[cli]`, and a `BerriAI/homebrew-litellm` tap
formula with a release runbook under `packaging/homebrew/`. The installer passes
no `--python`, so uv honours litellm's requires-python and provisions a managed
interpreter, skipping a too-old (3.9) or too-new (3.14+) system Python instead
of failing to resolve.
A pyproject thin-contract test asserts the `cli` extra keeps the deps the CLI
imports and never leaks a server-only dependency from `proxy`, so the laptop
install cannot silently re-bloat
* fix(install): let uv pick the Python via --python-preference system
Both installers detected a system Python with a floor-only check and forced it
with `uv tool install --python <interp>`. On a host whose only Python is outside
litellm's requires-python (a too-old 3.9 or, increasingly, a too-new 3.14) that
forced an incompatible interpreter and the resolve failed. Drop the detection and
pass `--python-preference system`: uv reuses a compatible system Python when
present and downloads a managed one otherwise, always honouring requires-python
* test(router): filter aiohttp unclosed-session gc noise in test_async_fallbacks
test_async_fallbacks asserts the last three captured log records are the
router's fallback messages. Under the litellm_router_testing job (pytest -k
router -n 4) many router tests share the module-level in_memory_llm_clients_cache
(max 200, ttl 3600s). Older cached OpenAI/Azure clients get evicted while their
aiohttp ClientSession is still open, and when the gc reclaims them aiohttp emits
"Unclosed client session"/"Unclosed connector" through the asyncio logger.
Those records land in caplog mid-test and push the expected router logs out of
the last-three window, so the assertion flips to failing non-deterministically.
These warnings are async cleanup noise, not router debug logs, so filter them
out exactly like the existing leaked-task warnings before asserting order. The
assertion on the three router fallback messages is unchanged.

Raise the PyJWT floor in pyproject (>=2.13.0,<3.0) and re-resolve uv.lock so
the proxy installs 2.13.0 instead of 2.12.0. Bump the ws transitive-version
override in the dashboard from 8.19.0 to 8.20.1 and regenerate package-lock;
jsdom and openai both dedupe onto the single 8.20.1 copy.
Both are routine dependency maintenance bumps to keep pinned versions current.
* fix(deps): bump vulnerable proxy dependencies (starlette/fastapi, granian, pyarrow, semantic-router)
Resolve known CVEs flagged by osv-scanner/grype against uv.lock. All bumped
versions verified to resolve, install, and pass the proxy auth/route/middleware
unit suites (717 tests) plus an import smoke on the new stack.
- starlette 0.50.0 -> 1.1.0 (CVE-2026-48710 "BadHost", GHSA-86qp-5c8j-p5mr):
versions <1.0.1 reconstruct request.url from the unvalidated Host header,
poisoning request.url.path. Required raising fastapi 0.124.4 -> 0.136.3,
which dropped fastapi's starlette<0.51.0 cap; an explicit starlette>=1.0.1
floor blocks regression to a vulnerable transitive resolution. The proxy's
own auth already reads scope["path"] via get_request_route, but the locked
starlette still flagged in container scanners and left other request.url
consumers exposed.
- granian 2.5.7 -> 2.7.4 (CVE-2026-42544, unauthenticated DoS via WebSocket
subprotocol header panic; CVE-2026-42545, WSGI response-header-panic DoS).
granian is a selectable proxy server (proxy_cli).
- pyarrow 22.0.0 -> 23.0.1 (CVE-2026-25087 / PYSEC-2026-113).
- semantic-router 0.1.12 -> 0.1.15: 0.1.12 was yanked (CVE-2026-42208 — its
unbounded litellm pin could resolve a credential-exfiltrating litellm==1.82.8
wheel).
Not fixable by bump: diskcache 5.6.3 (CVE-2025-69872, unsafe pickle
deserialization) has no upstream fix and is left pinned; exploiting it requires
write access to the local cache directory.
Relock side effect: sse-starlette 3.4.2 -> 3.4.4.
* deps: relax exact pins in optional extras to compatible ranges
The proxy/optional extras exact-pinned every dependency, which (1) forces
downstream `pip install litellm[proxy]` consumers into version lockstep and
(2) blocks them from pulling transitive security patches without forking — the
structural cause behind needing a litellm release to clear the starlette CVE in
the previous commit.
Convert the ordinary extras deps to `>=current,<next_major` ranges, mirroring
the core [project].dependencies style. Reproducibility for litellm's own
Docker/CI is unaffected: images install via `uv sync --frozen`, and the lock
re-resolves to the identical versions (no locked version changed).
Kept exact-pinned:
- litellm-proxy-extras, litellm-enterprise — litellm's own sub-packages,
versioned in lockstep with the release.
- opentelemetry-api/sdk/exporter-otlp — must resolve to matching versions.
- grpcio — supply-chain-pinned to a vetted, aged release.
Also corrects the stale comment claiming the extras are exact-pinned for Docker
reproducibility (the images use the lock, not these pins).
* fix(ci): resolve license-check lookup version from the floor for ranged deps
check_licenses.py derived the PyPI lookup version with
`next(iter(req.specifier))`, which returns an arbitrary specifier clause. For
a range like `>=0.12.1,<1.0` it picked the upper bound (`1.0`) — a version
that doesn't exist on PyPI — so the license lookup 404'd and the package was
flagged as having an unknown license.
The previous commit's switch from exact pins to ranges exposed this for
soundfile, pyroscope-io, redisvl, diskcache, and mlflow (the ranged deps not
already in liccheck.ini's allowlist). Prefer a lower-bound/exact version (a
real released version) for the lookup.
* fix(proxy): set strict_content_type=False on the FastAPI app
Starlette 1.0 / FastAPI 0.13x flipped the default to strict_content_type=True,
which refuses to parse a JSON request body when the client omits the
Content-Type header. The proxy previously accepted those requests, so the
fastapi/starlette bump in this PR would silently break clients that don't send
a Content-Type. Restore the prior lenient behavior explicitly.
