Pre-Submission checklist

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

  • I have Added testing in the tests/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

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.
  • Branch creation CI run

…icense check (#20567)

* fix: empty guardrails/policies arrays should not trigger enterprise license check (#20304)

The UI sends empty arrays for enterprise-only fields (guardrails, policies,
logging) even when the user has not configured these features. The backend
`is not None` check treated `[]` as a truthy intent to use the feature,
falsely requiring an enterprise license for basic team operations.

Backend: Add `and updated_kv[field] != [] and updated_kv[field] != {}`
guards in `_update_metadata_fields` so empty collections are skipped.

UI: Conditionally omit guardrails, logging, and policies from the
payload when empty instead of defaulting to `[]`.

Fixes #20304

* fix: allow clearing fields with empty collections while skipping enterprise check

Address PR review feedback:

1. Move the empty-collection guard into _update_metadata_field (singular)
   so that empty lists/dicts skip only the premium license check but still
   get written into metadata. This lets users intentionally clear a
   previously-set field (e.g. guardrails: []) without being blocked, while
   the UI's default empty arrays still don't trigger a false enterprise
   error.

2. Remove sys.path hack from test file; use standard imports that work
   with pytest discovery.

3. Add tests verifying that empty collections are moved into metadata
   (field clearing works) even though they bypass the premium check.

…ation (#20680)

Adds documentation for the litellm.proxy_auth feature that automatically
obtains and refreshes OAuth2/JWT tokens when connecting to a LiteLLM Proxy.
The VirtualKeysTable crashed when rendering keys with null or undefined
models field. The className expression tried to access .length on null,
throwing a TypeError that broke the entire keys table.

Added Array.isArray() guard before accessing .length on the models value.

Fixes #20611
* docs: add callback registration optimization to v1.81.9 release notes (#20681)

* Fix spend logs pickle error with Pydantic models

Replace copy.deepcopy() with Pydantic-safe serialization to avoid
"cannot pickle '_thread.RLock' object" errors when request/response
redaction is enabled.

Changes:
- Add _convert_to_json_serializable_dict() helper that uses
  model_dump() for Pydantic models instead of pickle
- Replace copy.deepcopy() calls in request and response redaction
  paths with the new helper function
- Recursively handles nested dicts, lists, and Pydantic models

Root cause: Pydantic v2 BaseModel instances contain internal
_thread.RLock objects for thread-safety. When copy.deepcopy()
attempts to pickle these objects, it fails because threading
primitives cannot be pickled.

Fixes #20647

* chore: remove unused copy import

Remove unused copy import that was causing lint failure. The copy.deepcopy()
calls were replaced with _convert_to_json_serializable_dict() helper function
in the previous commit, making the copy module no longer needed.

#20666)

Vertex AI requires Anthropic beta flags in the request body
(anthropic_beta array), not as HTTP headers. The Bedrock handler
already extracts user-specified beta headers from the headers dict,
but the Vertex handler was missing this, causing extra_headers like
interleaved-thinking-2025-05-14 to be silently dropped.

This extracts anthropic-beta values from optional_params extra_headers
and merges them into the anthropic_beta request body field, and also
removes extra_headers from the request body since the parent's
transform_request spreads optional_params into data.

first_id and last_id in the video list response were returned as raw
provider IDs while data[].id was properly wrapped with
encode_video_id_with_provider(). This caused pagination to break when
clients passed unencoded cursors back as the `after` parameter.

- Encode first_id/last_id in transform_video_list_response
- Decode the `after` param in transform_video_list_request via
  extract_original_video_id()
- Add 6 unit tests covering encoding, decoding, passthrough, and
  full round-trip pagination

Fixes #20708
