Verify Docker Image Signature

All LiteLLM Docker images are signed with cosign. Every release is signed with the same key introduced in commit 0112e53.

Verify using the pinned commit hash (recommended):

A commit hash is cryptographically immutable, so this is the strongest way to ensure you are using the original signing key:

cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/0112e53046018d726492c814b3644b7d376029d0/cosign.pub \
  ghcr.io/berriai/litellm:v1.83.7.rc.1

Verify using the release tag (convenience):

Tags are protected in this repository and resolve to the same key. This option is easier to read but relies on tag protection rules:

cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/v1.83.7.rc.1/cosign.pub \
  ghcr.io/berriai/litellm:v1.83.7.rc.1

Expected output:

The following checks were performed on each of these signatures:
  - The cosign claims were validated
  - The signatures were verified against the specified public key

⚠️ Breaking Changes

Prometheus default latency histogram buckets reduced (#25527)

The default LATENCY_BUCKETS has been reduced from 35 to 18 boundaries. If you have existing Prometheus dashboards or PromQL SLO queries that reference specific le values (e.g. le="1.5", le="9.5"), those series will no longer exist after upgrading. Review and update any affected queries or dashboard panels.
