From a3cdf6c89540a8b171e119fa38f8b0aeca0ab66a Mon Sep 17 00:00:00 2001 From: David Steele Date: Mon, 2 Mar 2026 08:59:59 +0000 Subject: [PATCH 01/87] fix(streaming): don't emit finish_reason on output_item.done for function_call MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The response.output_item.done handler for function_call type was emitting finish_reason='tool_calls' and a duplicate tool_call delta. This caused premature stream termination after the first tool call in multi-tool scenarios — downstream wrappers (e.g. AnthropicStreamWrapper) would close the stream before subsequent tool calls arrived. The response.completed event already inspects the response output list and emits finish_reason='tool_calls' when function_call items are present, so output_item.done does not need to (and must not) do so. This mirrors the existing fix for message-type output_item.done (#17246). Updated test_function_call_done_emits_is_finished (renamed) to assert finish_reason=None and no duplicate delta. Updated test_text_plus_tool_calls_sequence to match. Added test_multi_tool_call_stream_no_premature_finish which exercises a synthetic 2-tool-call stream and verifies no premature termination. --- .../transformation.py | 8 +- ...responses_transformation_transformation.py | 174 +++++++++++++++++- 2 files changed, 170 insertions(+), 12 deletions(-) diff --git a/litellm/completion_extras/litellm_responses_transformation/transformation.py b/litellm/completion_extras/litellm_responses_transformation/transformation.py index 1704861686e..e0e47a48b9d 100644 --- a/litellm/completion_extras/litellm_responses_transformation/transformation.py +++ b/litellm/completion_extras/litellm_responses_transformation/transformation.py @@ -1025,12 +1025,16 @@ class OpenAiResponsesToChatCompletionStreamIterator(BaseModelResponseIterator): if provider_specific_fields: tool_call_chunk.provider_specific_fields = provider_specific_fields # type: ignore + # Do NOT emit finish_reason here — response.completed handles the terminal + # finish_reason.

Previously users had to use this as a generic openai_compatible provider, which resulted in incorrect pricing (OpenAI rates instead of Bedrock rates). Changes: - New `BedrockMantleChatConfig` extending `OpenAILikeChatConfig` - Regional API base: `https://bedrock-mantle.{region}.api.aws/v1` - Auth via `BEDROCK_MANTLE_API_KEY` env var - Region resolution: BEDROCK_MANTLE_REGION > AWS_REGION > us-east-1 - Supports reasoning for gpt-oss models - Added `BEDROCK_MANTLE` to `LlmProviders` enum - Added 4 models with correct AWS Bedrock pricing to both pricing files: - bedrock_mantle/openai.gpt-oss-120b ($0.15/M in, $0.60/M out) - bedrock_mantle/openai.gpt-oss-20b ($0.075/M in, $0.30/M out) - bedrock_mantle/openai.gpt-oss-safeguard-120b - bedrock_mantle/openai.gpt-oss-safeguard-20b - Wired provider into get_llm_provider_logic, get_supported_openai_params, main.py routing, utils.py map_openai_params + ProviderConfigManager, and _lazy_imports_registry - 19 unit tests covering registration, config, provider resolution, pricing Usage: os.environ["BEDROCK_MANTLE_API_KEY"] = "your-key" litellm.completion(model="bedrock_mantle/openai.gpt-oss-120b", ...)

Kankute Date: Thu, 5 Mar 2026 14:34:11 +0530 Subject: [PATCH 23/87] feat(ui/agents): add Authentication Headers section to agent create/edit form Add a new "Authentication Headers" panel to AgentFormFields: - Static Headers: key-value Form.List (always sent to the backend agent, static wins on conflict with dynamic) - Forward Client Headers: Select[tags] of header names to extract from the client request and forward (extra_headers) Update buildAgentDataFromForm to serialize both fields for the API. Update parseAgentForForm to deserialize them back for editing. Covers both the create wizard (add_agent_form) and the edit view (agent_info).
