- Add whitelist-based filtering for anthropic_beta headers
- Only allow Bedrock-supported beta flags (computer-use, tool-search, etc.)
- Filter out unsupported flags like mcp-servers, structured-outputs
- Remove output_format parameter from Bedrock Invoke requests
- Force tool-based structured outputs when response_format is used
Fixes#16726
Added test cases for custom model names containing slashes in Vertex AI
passthrough URLs (e.g., gcp/google/gemini-2.5-flash).
Test cases:
- gcp/google/gemini-2.5-flash
- gcp/google/gemini-3-flash-preview
- custom/model
Extend advanced-tool-use header translation to include Claude Sonnet 4.5
in addition to Opus 4.5 on Bedrock Invoke API.
When Claude Code sends the advanced-tool-use-2025-11-20 header, it now
gets correctly translated to Bedrock-specific headers for both:
- Claude Opus 4.5
- Claude Sonnet 4.5
Headers translated:
- tool-search-tool-2025-10-19
- tool-examples-2025-10-29
Fixes defer_loading validation error on Bedrock with Sonnet 4.5.

The error message for DISABLE_ADMIN_ENDPOINTS incorrectly said
"DISABLING LLM API ENDPOINTS is an Enterprise feature" instead of
"DISABLING ADMIN ENDPOINTS is an Enterprise feature".
This was a copy-paste bug from the is_llm_api_route_disabled() function.
Added regression tests to verify both error messages are correct.
* feat: add feature to make silent calls
* add test or silent feat
* add docs for silent feat
* fix lint issues and UI logs
* add docs of ab testing and deep copy
Azure audio models were charging audio output tokens at the text token
rate instead of the correct audio token rate. This resulted in costs
being ~6.65x lower than expected.
The fix replaces Azure's custom cost calculation logic with the generic
cost calculator that properly handles text, audio, cached, reasoning,
and image tokens.
Fixes#19764
When using the responses API with provider-specific params (aws_*, vertex_*)
without explicitly passing custom_llm_provider, the code crashed with:
AttributeError: 'NoneType' object has no attribute 'startswith'
Root cause: local_vars was captured via locals() before get_llm_provider()
detected the provider from the model string (e.g., "bedrock/..."), so
custom_llm_provider remained None when processing provider-specific params.
Fix: Update local_vars["custom_llm_provider"] after get_llm_provider() call
so the detected provider is available for param processing.
Affected provider-specific params:
- aws_* (aws_region_name, aws_access_key_id, etc.) for Bedrock/SageMaker
- vertex_* (vertex_project, vertex_location, etc.) for Vertex AI
* Fix broken mocks in 6 flaky tests to prevent real API calls
Added network-level HTTP blocking using respx to prevent tests from making real API calls when Python-level mocks fail. This makes tests more reliable and retryable in CI.
Changes:
- Azure OIDC test: Added Azure Identity SDK mock to prevent real Azure calls
- Vector store test: Added @respx.mock decorator to block HTTP requests
- Resend email tests (3): Added @respx.mock decorator for all 3 test functions
- SendGrid email test: Added @respx.mock decorator
All test assertions and verification logic remain unchanged - only added safety nets to catch leaked API calls.
* Fix failing OIDC secret manager tests
Fixed two test failures in test_secret_managers_main.py:
1. test_oidc_azure_ad_token_success: Corrected the patch path for get_bearer_token_provider from 'litellm.secret_managers.get_azure_ad_token_provider.get_bearer_token_provider' to 'azure.identity.get_bearer_token_provider' since the function is imported from azure.identity.
2. test_oidc_google_success: Added @patch('httpx.Client') decorator to prevent any real HTTP connections during test execution, resolving httpx.ConnectError issues.
Both tests now pass successfully.
* Fix PLR0915: Extract system message handling to reduce statement count
* fix mypy
* fix: add host_progress_callback parameter to mock_call_tool in test
The test_call_tool_without_broken_pipe_error was failing because the mock function did not accept the host_progress_callback keyword argument that the actual implementation passes to client.call_tool(). Updated the mock to accept this parameter to match the real implementation signature.
* fixing flaky tests around oidc and email
* Add documentation comment to test file
* add retry
* add dependency
* increase retry
