ChainThink 消息，9 月 11 日，OpenAI 正式推出 Agents API 公测版，向所有开发者开放此前支撑 Codex 与企业版 ChatGPT 的代理框架。

开发者可通过 API 构建生产级 AI 代理，费用按 Token 消耗及工具调用量计费。

该 API 支持长时运行与复杂任务，开发者一次调用即可指定任务、模型、工具及运行环境，核心能力包括上下文自动压缩、工具并行调用和多代理协同，可连续运行数小时至数天。

客户案例显示，SafetyKit 接入后单案处理成本下降 60%，Hypha 代理响应失败率降低 86%，Cirridae 评估得分由 0.71 升至 0.85，延迟降低 4 倍。

基础设施方面，Agents API 使用与 Codex、ChatGPT 相同的沙箱环境，已接入 Blaxel、Cloudflare、DigitalOcean、甲骨文、Vercel 等合作伙伴，支持不同 CPU、GPU、内存及部署环境。

官方表示，Agents API 基于开源 Codex 执行框架构建，并支持 MCP、自定义函数和网页搜索等工具。

此次开放意味着 Codex 从 AI 编程产品扩展为面向开发者的代理基础设施平台。
