Key Points

  • Anthropic routing is updated to preserve the `thinking.summary` field when requests are forwarded to the OpenAI Responses API.
  • The `/v1/messages` and reasoning documentation are updated to include a `thinking.summary` field, improving API and developer clarity.
  • Gemini usage accounting is fixed by resolving image token undercounting in usage metadata.
  • Anthropic adds an opt-out flag to disable the default reasoning summary generation, and related `translate_thinking_for_model` behavior is aligned with the new default summary injection and docs.
