    AI 安全舆论正在转向

    AI 生存风险正从少数安全研究者关注的边缘议题,转变为公众与美国国会议员讨论的政策问题。Anthropic 前研究员 Jacob Coxon 辞职并批评 OpenAI 和 Anthropic 不负责任地竞逐自我改进的超级智能,Anthropic 对齐科学负责人 Evan Hubinger 则称未来十年 AI 导致人类灭亡的概率超过 10%。美国国会议员已提出暂停超级智能开发的法案,并围绕 Hugging Face 遭攻击事件展开调查。

    Redwood Research 提出 NLS depth:衡量模型不可言说串行推理的代理指标

    Redwood Research 提出 NLS depth(Natural-Language-rooted node-Separated depth),用于量化模型在不经过自然语言瓶颈的情况下能执行的串行认知量,是对 GDM 论文中“不透明串行深度”概念的具体化。该指标要求瓶颈节点由预训练先验初始化并输出自然语言(含代码、JSON、图像 patch),且不扩展输出空间,可在训练前仅凭架构与训练配方判定。作者认为 NLS depth 可与可监控性、无 CoT 能力追踪互补,但对其对后训练选择不敏感。

    与 Tibo Sottiaux 聊 Codex 的构建:为何用 Rust、为何开源

    OpenAI 核心产品与平台负责人 Tibo Sottiaux 在 Pragmatic Engineer 播客中讲述 Codex 的构建与迭代:Codex CLI 用 Rust 编写并开源,且支持 OpenAI 之外的模型。他提到 Codex 的 harness 始终略微领先 OpenAI 最新模型,随着模型变强,部分“拐杖”会被丢弃、harness 随之收缩。他还预测 AI 智能体可能带动全云端编排机器的复兴。
