On August 30, 2026, Simon Willison published an article titled “Understanding ChatGPT Work,” which delves into the working process of ChatGPT. The report summarizes consensus facts regarding the reasoning process of large language models, prompt engineering optimization, and the internal mechanisms of the system, aiming to help developers and users understand how AI generates responses and potential areas for improvement.
OpenAI 于 7 月 9 日推出 ChatGPT Work，目前仅限 $20/月起订阅用户访问。该产品分为云端版（Work Cloud）和本地版（Work Local），本文聚焦云端功能。与免费或 $8/月 Go 用户可用的普通 Chat 相比，ChatGPT Work 支持 Luna、Terra 替代 Sol 模型，提供带互联网访问的代码执行环境、无头 Chrome 浏览器、持久文件系统、发布 ChatGPT Sites 及子代理会话能力。用户可在 GPT-5.6（Sol/Luna/Terra）及 GPT-5.5 的不同推理级别间选择，而 Chat 仅提供特定模型组合且部分高级功能需 $100/月订阅。代码执行环境可联网安装软件包并交互网站 API，这是 Chat 无法实现的突破。
