    AI 聊天机器人隐私问题:如何保护个人信息安全

    斯坦福 HAI 隐私与数据政策研究员 Jennifer King 指出,ChatGPT、Claude、Gemini 等工具会存储用户对话并用于训练大模型,但用户可删除历史记录或关闭部分功能。她建议不要上传未脱敏的医疗等敏感文件,尽量使用临时对话、关闭数据训练选项,并定期查看政策更新。

    开放模型当前的力量格局:中国实验室为何领先

    Interconnects 作者 Nathan Lambert 公开其为美国国会成员及幕僚准备的开放权重模型简报讲稿,梳理中美在开放模型上的力量对比。文中称自 2025 年 4 月起中国 AI 公司已是开放权重模型的明显领先者,Hugging Face 下载量上中国约为美国的 2 倍(3.2B 对 1.6B),Artificial Analysis 智能指数上中国开放模型领先美国同类,中国开放权重模型约落后美国闭源前沿 2-5 个月。作者还引用 OpenRouter 数据称开放模型周处理量从 2025 年 9 月的约 1T tokens 增至如今的约 80T tokens,中国模型份额从约 70% 升至 80% 以上,并认为知识蒸馏只能解释 1-2 个月的差距。

    具身智能赛道半年内多位核心高管离职

    过去半年,具身智能赛道出现核心高管密集离职,智元罗剑岚、鹿明丁琰、小鹏米良川等相继离场,小鹏机器人“铁三角”彻底拆散。文章将原因指向技术路线分歧与资本时间表错配,资本要求三年退出而技术成熟需五到十年。多数离职者仍留在具身智能领域创业或加入新公司,作者认为这更像行业从技术竞赛转向商业竞赛的组织阵痛。

    KDE 迎来 30 周年,Akademy 大会出现 AI 原生桌面提案
