📄 中文摘要
OpenAI最近推出了重新设计的ChatGPT购物体验，允许每周900万用户在对话中直观浏览产品、并进行选项对比和实时定价。该体验的核心协议是代理商务协议（ACP），这是OpenAI与Stripe共同开发的开放标准，采用Apache 2.0许可。ACP定义了AI代理与商家之间协调交易的共同语言，类似于ChatGPT（买方代理）与商家产品目录之间的API契约。重要的架构原则是OpenAI并不是交易的商家，商家对产品保持完全控制。

OpenAI's Agentic Commerce Protocol: a technical look at how ChatGPT becomes a shopping agent
OpenAI recently launched a redesigned shopping experience in ChatGPT, enabling 900 million weekly users to visually browse products, compare options, and access real-time pricing all within the conversation. The protocol driving this experience is called the Agentic Commerce Protocol (ACP), an open standard co-developed by OpenAI and Stripe under Apache 2.0. ACP defines a common language for AI agents and merchants to coordinate transactions, functioning as an API contract between ChatGPT (the buyer's agent) and a merchant's product catalog. A key architectural principle is that OpenAI is not the merchant of record, allowing merchants to retain full control over their products.
