Pre-Submission checklist

Please complete all items before asking a LiteLLM maintainer to review your PR

I have Added testing in the tests/test_litellm/ directory, Adding at least 1 test is a hard requirement - see details
My PR passes all unit tests on make test-unit
My PR's scope is as isolated as possible, it only solves 1 specific problem
[] I have requested a Greptile review by commenting @greptileai and received a Confidence Score of at least 4/5 before requesting a maintainer review

CI (LiteLLM team)

CI status guideline:

50-55 passing tests: main is stable with minor issues.

45-49 passing tests: acceptable but needs attention

<= 40 passing tests: unstable; be careful with your merges and assess the risk.

Changes

This PR migrates the repository from Poetry / ad hoc pip install paths to uv across packaging, CI, Docker, and contributor workflows.

Main changes:

Convert root and workspace package metadata from Poetry layout to PEP 621 + uv workspace metadata
Add and commit uv.lock, remove Poetry lockfiles, and move active install paths to uv sync --frozen
Update GitHub Actions, CircleCI, Makefile, publish scripts, devcontainer setup, and contributor docs to use uv
Migrate Docker build/install paths to uv and preserve runtime dependency parity for the proxy images
Fix the health-check image so dependencies are installed at build time, not resolved at container startup
Remove active Poetry / requirements.txt dependencies from release and validation paths
Tighten uv-related pinning for build and CI tooling
Add test-isolation fixes under tests/test_litellm/
Stub live image download dependencies in the Bedrock request-formatting test so it only validates request shaping

Local verification run:

uv lock --check
uv build --package litellm
uv build --package litellm-enterprise
uv build --package litellm-proxy-extras
uv run --no-sync pytest tests/test_litellm/test_main.py::test_url_with_format_param -q
docker build -f docker/Dockerfile.health_check -t litellm-healthcheck-test .

Notes:

The branch is intentionally split into focused commits for packaging, CI, Docker, docs, tests, and pinning hardening.

Looks like the CodSpeed benchmark regressions may be as a result of it running in a different environment

The conflict resolution imported only the function but the test body references check_migration as a module throughout. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…Docker layer caching - Move google-generativeai, Pillow, tenacity back to ci group (they are lazily imported and bloat the base SDK install needlessly) - Remove nodejs-wheel-binaries from extra_proxy and proxy-dev (redundant in Docker where system Node.js is already installed via apk) - Remove all nodejs-wheel node replacement and venv npm patching blocks from Dockerfiles since the wheel is no longer installed - Add --no-default-groups to CodSpeed benchmark workflow so the benchmark environment matches the old minimal pip install footprint - Apply standard uv two-phase Docker pattern: copy metadata first, install deps (cached layer), then copy source and install project - Replace CircleCI enterprise no-op with proper uv sync command Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The old workflow used actions/cache/restore (read-only). The uv migration changed it to actions/cache (read-write), which zizmor flags as a cache poisoning risk. Restore the safer read-only variant. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…lert The setup-uv action enables caching by default, which zizmor flags as a cache poisoning risk. Disable it since we already use a read-only cache/restore step. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Silences zizmor cache-poisoning alert. Publishing workflow runs infrequently on protected branches so caching adds no real benefit. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Add redis_caching_coverage to coverage combine list (from upstream) - Remove e2e_ui_testing job (deleted upstream) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The logger was patched twice — first via mocker.patch() then via mocker.patch.object(autospec=True). The second call fails because autospec cannot inspect an already-mocked attribute. Remove the redundant first patch. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The Dockerfile.non_root build ran out of disk on the CI runner. Remove Android SDK, .NET, Boost, and GHC toolchains (~12GB) to free space. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Sync CI configs with upstream/litellm_internal_staging: - Migrate from Poetry to uv (PR #25007) - Pull in zizmor security fixes for workflows - Add isolated unit test workflows + reusable bases - Drop redundant matrix workflow and azure-batches workflow - Drop .circleci/requirements.txt (replaced by uv lockfile)
