    Circuit Breaker Labs 希望让 AI 对孩子(和你)更安全

    TechCrunch 2026 Startup Battlefield 200 决赛入围者 Circuit Breaker Labs 打造了一支“碰撞测试假人”式 AI 智能体队伍,模拟不同年龄、背景、语言和文化的用户,对模型进行红队测试,每天运行数万到数十万次模拟交互,以检测危险、心理有害的互动。该公司目前作为高风险 AI 应用的安全测试实验室运营,仅有 5 名员工。

    Apple 正在研发代号 J450 的 AI 安防摄像头,据 Bloomberg 的 Mark Gurman 称,它不录制任何视频,而是通过低帧率传感器和端侧 AI 向用户提供家中活动的文字描述,并支持人脸识别标记有人进入房间等事件。该摄像头与传闻中的 J490 智能家居中枢配对,并共享 Apple 带摄像头 AirPods 的技术。它能否在真正出事时仅靠文字描述满足需求,仍有待观察。
