原标题：Anthropic takes on Grok Bot, Meta's Muse, and OpenAI's Dots with its always-on agent "Claude Duet"
AI 摘要
Anthropic 发布 Claude Duet 研究预览版，这是一款常驻后台的主动式 AI 代理应用，运行在云端虚拟机上，可连接 Gmail、Slack、Stripe 等 6000 多个连接器，替用户安排会议、准备账单等任务。该产品对标 SpaceXAI 的 Grok Bot、Meta 的 Muse 和 OpenAI 的 Dots，面向美国 Pro 和 Max 订阅者以候补名单方式开放。Duet 在发送消息、付款、签署文件等敏感操作前必须获得用户批准，禁止证券交易和账户间转账，并采用凭证隔离、提示注入防御和新分类器保护敏感数据。Anthropic 承认早期版本存在误读消息、判断紧急程度不准、个人事务能力较弱等局限，且后台检查受订阅额度限制。
