* fix: resolve mypy type errors in hiddenlayer guardrail and transformation
- Fix return type of apply_guardrail from str to GenericGuardrailAPIInputs
- Add None checks for logging_obj before accessing attributes
- Convert AllMessageValues to dict format for HiddenLayer API compatibility
- Fix payload type annotation in _call_hiddenlayer
- Ensure transformed_output always returns list[dict[str, Any]] in transformation.py
* fix: use litellm_call_id as trace_id fallback in langfuse logging
- Only use standard_logging_object.trace_id if explicitly set via litellm_session_id or litellm_trace_id params
- Fallback to litellm_call_id when no explicit trace_id is provided (matches test expectation)
- Return the trace_id we set instead of generation_client.trace_id for consistency
- Add warning if langfuse modifies the trace_id to help debug potential issues
Fixes test_logging_trace_id test failure where auto-generated UUID was used instead of litellm_call_id
* fix: document envs
* fix: handle None response in /spend/logs endpoint when no records found
- Return empty list [] instead of [None] when spend_log is None
- Prevents 500 errors when querying by request_id, api_key, or user_id with no matching records
- Fixes test_chat_completion_bad_model_with_spend_logs test failure
* fix: use standard_logging_object trace_id when available in langfuse logger
- Fix trace_id selection logic to use standard_logging_object.trace_id when available
- Previously only used standard_logging_object.trace_id if explicitly set via params
- Now uses standard_logging_object.trace_id whenever it's present, matching test expectations
- Falls back to litellm_call_id if no trace_id is found
- Fixes test_log_langfuse_v2_uses_standard_trace_id_when_available test failure
When using litellm.completion() with model="openai/responses/...", images
in tool message content were not being transformed from Chat Completion
format to Responses API format.
Chat Completion format: {"type": "image_url", "image_url": {"url": "..."}}
Responses API format: {"type": "input_image", "image_url": "..."}
This caused OpenAI to reject the request with error 400 since "image_url"
is not a valid type for function_call_output content.
This fix addresses two issues with Anthropic web search streaming:
1. Fix trailing {} in tool call arguments
- web_search_tool_result blocks have input_json_delta events that were
incorrectly emitted as tool calls
- Added current_content_block_type tracking to only emit tool calls for
tool_use and server_tool_use blocks
2. Capture web_search_tool_result for multi-turn
- The web_search_tool_result content comes ALL AT ONCE in content_block_start
- Now captured in provider_specific_fields.web_search_results
- stream_chunk_builder combines these for final message
- Allows multi-turn conversations to work with streaming web search
Add support for the Bedrock Converse API serviceTier parameter to allow
specifying processing tier (priority, default, or flex).
Changes:
- Add ServiceTierBlock type in litellm/types/llms/bedrock.py
- Add serviceTier to CommonRequestObject
- Add serviceTier to get_config_blocks() in AmazonConverseConfig
- Add comprehensive tests for serviceTier functionality
- Add documentation for serviceTier usage
This allows users to configure service tier via:
- litellm_params in proxy config
- optional_params in SDK calls
* fix(azure_ai): Remove unsupported params from Azure AI Anthropic requests
Azure AI Anthropic endpoint rejects max_retries and stream_options parameters
with "Extra inputs are not permitted" error. These are LiteLLM-internal
parameters that should not be sent to the API.
Fixes 400 Bad Request error when using azure_ai/claude-sonnet-4-5 and other
Azure AI Anthropic models.
* test(azure_ai): Add test for unsupported params removal in Azure AI Anthropic
Verifies that max_retries, stream_options, and extra_body are properly
removed from the request before sending to Azure AI Anthropic endpoint.
