同为国内头部互联网公司的腾讯与字节跳动，近年来在多个领域存在商业竞争，因此豆包AI手机登录 微信"被动下线"引发关注，在社交平台上有用户用"二选一"等字眼描述此事。 对此，新华财经从相关人士处获悉，微信未有特别动作，和商业竞争也没有关系，不排除是由于微信的 安全风控措施导致。 2日晚间开始，陆续有用户反馈称，使用"豆包AI手机"登录微信后被动下线，并提示"微信登录环境存在 异常"。 据悉，豆包AI手机即为近日少量发售的搭载豆包手机助手技术预览版的工程样机努比亚M153，其在操 作系统层面搭载了字节跳动旗下豆包团队的手机助手。 据悉，微信在官方协议中明确规定有用户不得利用微信进行任何形式的自动化操作，不得使用任何未经 腾讯授权的插件、外挂、系统或第三方工具。 有头部互联网产品人士向新华财经表示，目前市面上的AI助手提供的AI Agent服务就属于自动化操作的 范畴。 据了解，豆包AI手机在今日限制部分功能对微信的调用后，手机已经可以正常使用微信。 新华财经尝试使用其他品牌手机内置的AI助手通过语音指令调用微信给好友发送消息，亦被提示目前 不支持该功能。 据悉，今年手机厂商纷纷在产品中内置AI Agent服务，即 ...

现在的AI 如果不被手机操作系统接纳，就只能是一个聊天机器人玩具；只有进入系统底层，才能成为 真正的"助手"。 在AI的时代，传统的APP孤岛会被彻底击穿。当然，这条路注定充满荆棘。这背后更 深层次的问题是权限。 豆包官方表示，在手机助手的落地路径上，没有自研手机计划，目前正与多家手机厂商洽谈，以"生态 合作"形式将豆包手机助手整合进不同品牌机型中，相关进展将在后续公布。 这一战略背后，是字节跳动对AI时代人机交互入口的全面争夺。字节正在积极探索硬件入口，以手机 为代表的智能终端，是AI最直接的落地场景。 当下的主流手机厂商纷纷自研端侧AI，比如苹果的Siri、三星的Bixby、华为的小艺、小米的小爱。今年 10月份vivo、OPPO、荣耀扎堆发新品，手机AI智能体成为了主打卖点。 主流手机厂商这种"生态系统闭环"策略，让大模型厂商急需找到属于自己的端侧入口，集成和释放AI能 力。豆包此次选择以"AI手机助手"形态切入，正是看准了这一点。 2025年9月，手机厂商AI助手用户规模达到了5.35亿，这是检验上游端侧模型技术的"试金石"。当下， 手机AI助手的行业趋势是从"功能模块"升级为"生态中枢"，通过系统级 ...
