We are replacing the existing GPT-4o-based model for Operator with a version based on OpenAI o3. The API version will remain based on 4o.

Codex is a cloud-based coding agent. Codex is powered by codex-1, a version of OpenAI o3 optimized for software engineering. codex-1 was trained using reinforcement learning on real-world coding tasks in a variety of environments to generate code that closely mirrors human style and PR preferences, adheres precisely to instructions, and iteratively runs tests until passing results are achieved.

Codex 简介：基于云的软件工程智能体，可并行处理多项任务，由 Codex-1 提供支持。有了 Codex，开发人员可以同时部署多个智能体来独立处理编码任务，如编写功能、回答有关代码库的问题、修复错误以及提出拉取请求以供审核。
