fix(reasoning): skip duplicate callback for <think>-extracted reasoning during streaming - #3116
Merged
Conversation
…ng during streaming Local models (Ollama, LM Studio) embed reasoning in <think> tags in delta.content. During streaming, _stream_delta() already displays these blocks. Then _build_assistant_message() extracts them again and fires reasoning_callback, causing duplicate display. Track whether reasoning came from structured fields (reasoning_content) vs <think> tag extraction. Only fire the callback for <think>-extracted reasoning when stream_delta_callback is NOT active. Structured reasoning always fires regardless. Salvaged from PR #2076 by dusterbloom (Fix A only — Fix B was already covered by PR #3013's _current_reasoning_callback centralization). Closes #2069.
