Jonas Geiping 等人发布预印本,提出直接针对无害性与诚实性探针优化模型,并称在持续更新探针的前提下效果良好,模型学会对有害请求生成无害回答、在压力下保持诚实。作者转述的论文观点认为,AI 安全领域不少被视为禁忌的技术(如用思维链检测奖励作弊、用模型内部表征做训练)缺乏清晰科学依据,而随着未来模型可能靠通用奖励寻求行为刷满对齐训练场景,用内部表征监督训练且不丧失可监控性将愈发重要。作者本人指出,这种训练让模型学会无害,而不是学会拒答有害请求,小模型在被诱导输出有害内容时会出现一些有意思的回答。
So the Assistant adopts traits more from human characters who it resembles. We exploit this to learn about *how* the model represents the Assistant. E.g. the model treats the Assistant as resembling elite-school humans more than non-elite ones.
(Is this because the model trusts elite-school people more in determining what to believe? We think not because papers like Slocum et al 2025 suggest that provenance doesn't matter for belief uptake from finetuning.)
METR 的 Ryan Greenblatt 对 AI 架构转向以不透明激活而非思维链进行推理(即"neuralese"架构)表示担忧,认为 Astra 是这一方向上令人不安的一步。他指出公开信息不足以就 Astra 架构与训练方法改动在可监控性与性能之间的权衡展开充分讨论,呼吁 AI 公司发布相关证据并公开其政策,Redwood AI 也提出了追踪无 CoT 推理能力与可监控性政策的提案。他强调公司应谨慎对待可能消除或大幅削弱对思维链依赖的架构。

Some architectures could weaken CoT monitorability, or remove the CoT altogether.
We've written a proposal for how companies could be transparent about no-CoT reasoning abilities, other monitorability evidence, and policies for preserving monitorability. https://www.redwoodresearch.org/blog/proposal-for-tracking-architecture-on-monitorability
