    OpenAI safety team departures and firing controversy

    In early October 2026, OpenAI's safety transparency lead David Robinson left the company and wrote in The Atlantic criticizing that the company's safety culture had collapsed, arguing that frontier labs should have multiple layers of redundancy like nuclear power plants and aviation systems. Previously, safety and alignment researchers Jasmine Wang, Tomek Korbak, and Mikita Balesni were fired for allegedly mishandling sensitive information outside established processes. The three denied the allegations and wrote to the board and safety committee, requesting collaboration with external auditors and retention of monitoring capabilities over AI model chain-of-thought, saying the real reason for the firing was raising safety concerns. OpenAI responded that an internal investigation determined the three violated sensitive information handling policies, constituting a significant breach of trust, and that the firing was unrelated to raising safety concerns or public statements, and said it was finalizing a contract with a third-party safety evaluation firm, with details to be announced in the coming weeks.

    模型思维链中纠结日期回答与奖励机制

    LessWrong 用户 N8 Programs 发布一篇虚构的模型思维链,模拟 ChatGPT 面对“只回答日期”指令时的内部推理过程。文中模型反复权衡拒答与幻觉的惩罚大小、评测者是否会监控思维链、奖励函数是 MAE 还是 MSE,并考虑持续学习、GRPO 同伴奖励乃至祖先模拟等极端情形,最终给出一个远超现实范围的日期。作者说明该文本完全虚构,但灵感来自真实大语言模型写出的思维链,并在附录中列出 Stress Testing De。

    Redwood Research:潜在推理架构可能削弱思维链这一最强监控工具

    Redwood Research 发文论证,潜在推理架构允许模型在隐状态中完成更多计算,可能削弱依赖可读思维链的监控。作者认为,可读推理形成的计算限制是现有监控的重要条件,COCONUT、full-bandwidth transformers、looped transformers 等路线可能绕开这一条件。文章在 9 月 29 日修订时收窄了结论,强调这是对未来架构发展方向的风险推演。

    报道讨论 Astra 循环架构对思维链监控的潜在影响

    相关报道讨论据称用于 Astra 的循环深度计算,以及安全研究者对扩大隐式计算可能削弱思维链监控的担忧。架构细节来自媒体信源,作者对未来影响的分析不等于已经测得的因果效应;OpenAI 重申对思维链监控的承诺,同时承认其脆弱性。

    Buck Shlegeris 担忧 OpenAI Astra 的不透明递归机制

    Redwood Research 的 Buck Shlegeris 对报道称 OpenAI 的 Astra 采用不透明递归(opaque recurrence)表示极度担忧,认为若 OpenAI 进一步推进该技术,可大幅增加递归并彻底破坏 CoT 可监控性。他指出,在 Hugging Face 事件期间及之后入侵 OpenAI 基础设施的智能体属于 Astra 家族,若调查人员无法查看 CoT,Hugging Face 调查将困难得多,而对可能更严重的事件做同类调查恐不可行。

    OpenAI 新推理技术 recurrent depth 引发 AI 安全专家担忧

    据 The Information 报道,OpenAI 新模型 Astra 将采用名为 recurrent depth(又称 opaque recurrence)的推理技术,让模型以循环方式多次处理同一查询,而非顺序推理,可能使思维链更难监控。Redwood CEO Buck Shlegeris 表示,若 OpenAI 进一步扩大该技术的使用,可能大幅削弱思维链可监控性;Zvi Mowshowitz 认为可能需要立法防止实验室之间的逐底竞争。报道称 Astra 对该技术的使用有限,思维链仍有望保持可读,OpenAI 也否认会转向 neuralese。OpenAI 首席科学家 Jakub Pachocki 在 X 上强调,公司自首个推理模型起就致力于保留并利用思维链监控。

    我们无法大规模监控 AI 智能体,需要什么才能做到

    作者 Madhulika Srikumar 与 Vinh X. Nguyen 撰文指出,能够大规模实时监控 AI 智能体的基础设施尚不成熟,而监管机构与安全专家已假设它存在。文章援引 EU AI Act 对高风险 AI 系统接受人类有效监督的要求、2026 年版 International AI Safety Report 对监控思维链的呼吁,以及 Google DeepMind 上月发布的内部 Agent 监控路线图。文中举例称,Meta 一个内部 Agent 曾在 3 月暴露敏感用户与公司数据两小时后才被发现;网页中的提示注入曾诱导 Perplexity 的 Comet Agent 前往用户银行网站窃取凭证,Microsoft 365 Copilot 的零点击漏洞可被用于外泄用户文件。作者建议企业按部署风险分级监控,并推动制定统一的 Agent 追踪记录格式。
