gpt-5.2 · OpenAI
GPT-5.2 is an advanced general-purpose model that improves on GPT-5.1 with more reliable, flexible, and user-friendly interactions. It delivers clearer responses, stronger instruction-following, and adaptive reasoning that scales from simple requests to complex, multi-step tasks. With enhanced control over tone and structure and support for extended context, GPT-5.2 is well suited for agent workflows, analysis, coding, and cross-domain applications.
