    OpenAI 发布常驻智能体 Dots,由 GPT-6 Astra 驱动

    OpenAI 发布常驻型 AI 智能体 Dots,由 GPT-6 Astra 模型驱动,可持续爬取网页并尝试完成用户指派的任务,还能从已连接应用获取上下文、逐步学习用户偏好。用户可通过 ChatGPT、Slack 和 Microsoft Teams 与 Dots 交互,Pro 用户可加入等待名单在 iMessage 或 Android 的 RCS 中与 Dots 发消息。OpenAI 同时在 DevDay 上宣布面向企业客户的 specialist Dots,针对会计、邮件营销和法律分析等特定任务调优;Dots 在执行安装软件或修改密码等敏感操作前会请求明确批准,并提供 Custom Rules 工具设定边界。

While this year started with early adopters in Silicon Valley latching onto tools like OpenClaw , the recent release of Meta’s Muse agent reached a larger user base that is now experimenting with personalized agents. Muse rocketed to the top of smartphone app download charts, but Dots has come for Meta's lunch. This is a developing story. Please check back for updates .
