Changes for version 0.25 - 2026-01-02
- Model Updates: Updated examples and internal constants to reflect the latest `gpt-5.2` series models.
- Evals API Introduction: Added a comprehensive set of endpoints for managing model evaluations, including creating evaluations, executing evaluation runs, and retrieving detailed output items.
- Audio API Enhancements:
- Introduced support for speaker diarization in transcriptions via the new `diarized_json` response format.
- Added new endpoints for managing Voice Consents and creating custom Voices.
- Conversations API Updates:
- Restructured conversation item management under the `/conversations/{conversation_id}/items` path.
- Added the `include` parameter to allow fetching enhanced metadata such as tool outputs and reasoning tokens.
- Realtime API (Beta) Updates: Expanded server events to include support for Model Context Protocol (MCP) tool calls and audio transcript deltas.
- Assistant API Enhancements:
- Added support for new tools, including `web_search_preview` and `computer_use_preview`.
- Introduced the `reasoning_effort` parameter and prompt cache retention policies for assistants.
- Batch API Expansion: Added support for including Moderations (`/v1/moderations`) in batch requests.
- Containers API: Added `memory_limit` configuration support for container objects.
- Documentation: Updated all code examples to prioritize the use of the `OPENAI_API_KEY` environment variable.
