GPT-5.2 pro is available in the Responses API only to enable support for multi-turn model interactions before responding to API requests, and other advanced API features in the future. Since GPT-5.2 pro is designed to tackle tough problems, some requests may take several minutes to finish. To avoid timeout, please set a longer timeout duration. It is recommended to use this under good network conditions.
