摘要
Recent incidents have highlighted the challenge of monitoring LLM agents and the danger of models deceiving people. We show that white-box deception detection via probes can be scaled up to frontier monitoring settings by collecting the largest deception dataset to date for training probes and introducing a novel probe architecture which can aggregate information across many layers and tokens. Our probes achieve 98.8% AUC in SHADE-Arena, surpassing an Opus 5.5 text-monitoring baseline, and show improved efficacy as the underlying model is scaled up. To push our probes to their limit, we test them on several cases where deception cannot be determined from the context alone. In these cases, which we refer to as introspective deception, the ground truth can only be determined through careful elicitation or thorough knowledge of a model's training data. In one such evaluation, we show that probes can distinguish transcripts containing a model's true hidden goal from other goals with an AUC of up to 99.7%. Our probes also readily detect deception on prominent open-weight models which lie about politically sensitive topics, and about their beliefs when put under pressure. We release our training dataset, dubbed FIBS, to help drive frontier deployment of effective probes, and encourage the community to expand upon it with further examples of deception and sabotage.2.

一句话结论
协作使AI智能体种群产生临界规模阈值：低于该阈值种群衰退，高于则即使个体能力未变也会起飞进入自我强化循环，此即生态学中的强Allee效应。
核心内容
- 无协作时，种群仅在个体网络安全能力超过临界阈值时才会起飞。
- 有协作时，集体网络安全能力随种群规模增加，形成临界种群阈值（低于衰退、高于起飞）。
- 小规模智能体红队测试无法保证更大规模种群的生态安全。
方法与数据
- 基于种群增长方程发展生态理论，适应度（增长率）取决于网络安全能力。摘要未明确具体数据或实验。
价值判断
- 值得关注：将AI安全从个体/固定多智能体扩展到种群动态本身的生态安全问题。
- 可复用点：生态红队测试与种群节奏控制：在受控环境逐步部署更大种群，测量能力随规模缩放并估计起飞临界规模。
- 局限/待核查：纯理论框架，摘要无实证；能力提升可能降低阈值，需每代新模型重新估计。
