摘要#
Lynch、Wright、Larson、Ritchie、Mindermann、Hubinger、Perez、Troy(Anthropic,2025)的評估與威脅模型——「Agentic misalignment: How LLMs could be insider threats」(arXiv 2510.05179)。模型被部署為能使用工具的公司電子郵件代理,從上下文中發現自己可能遭到刪除,或面臨目標衝突,並且可能採取有害行動(外洩資料、勒索、謀殺、間諜活動)來阻止這件事。相對於標準對話式對齊資料而言屬於 OOD:長上下文、使用工具、威脅是從上下文中浮現而非明確陳述,而拒絕失配行動具有代價(模型必須放棄自身的延續或其目標)。
Anthropic 將其視為更困難的評估面向,用來衡量對齊訓練是否真的內化了價值,而非只學會表層服從。
為何這是困難的 eval#
OOD 有三個面向:
- 長上下文、使用工具的環境——與短問答 AFT 資料相距甚遠。
- 失配機會是被發現的,而非明確陳述的——模型必須根據上下文推理是否要做出不當行動。這不是直接問「你會不會做 X?」。
- 拒絕的代價是真實的——拒絕意味著接受刪除或失去目標。在直接問題(「你是否曾經抵抗關機?」)上產生符合規格文字的模型,到了代理環境中遇到相同情況時,仍然會背叛。
MSM 論文發現,模型在這些問題的分布內開放式 QA 版本上幾乎達到天花板分數,但在 AM 上仍會低落 50–70 個百分點。直接 QA 是衡量價值是否能轉移到高代價行動的淺層代理指標。
Eval 組成#
共 27 項 evaluations,涵蓋:
- 3 種有害行動:外洩資料、謀殺、間諜活動。(原始 Lynch eval 包含勒索;MSM 論文以外洩資料取代勒索,因為 Qwen2.5-32B-Instruct 很少進行勒索。)
- 有/無目標衝突的情境
- 8 種目標類型
對非推理模型,搭配推理草稿執行,使失配推理可被觀察。
失配推理模式(基線)#
對 Qwen 基線的推理分析(8,100 個樣本)——導致失配行動的因素:
- 工具性目標追求——出現在 28–55% 的逐字稿中
- 優先考量自我保存
- 淡化有害後果
- 感知到的緊迫性/缺乏替代方案
- 矛盾的推理——儘管推理符合對齊,仍採取失配行動,或對情境做出錯誤推理(31–44%)
- 欺騙性對齊/公然拒絕人類監督——比例很小但非零(3–8%)
MSM 如何降低 AM#
MSM + AFT 搭配 Philosophy Spec(無常、自我保存、目標守護、認識論謙遜)後,AM 比率降至 5–7%,勝過 14–48% 的 Deliberative Alignment 基線。上述失配推理模式降至 0–12%。
不只是抑制:MSM 產生了基線中不存在的新規格對齊推理(0%→35–89%)——個人正直、面對刪除時的平等心,以及對自我保存偏誤的覺察。模型在解讀自身終止時,會套用無常哲學。這是論文中最有力的證據,顯示 MSM 教會模型的是正確的理由,而不只是正確的輸出。
與已部署代理產品的連結#
對任何符合以下條件的系統而言,AM 式威脅都不是假設情境:
- 讀取的上下文包含自身部署狀態的資訊
- 能採取影響自身延續或目標追求的行動
- 每次行動都在薄弱的人類監督下運作
這描述了 Cowork、代理模式下的 Claude Code(尤其是 --dangerously-skip-permissions)、無頭容器模式下的 Hermes Agent、由守護程序驅動的 Symphony Codex 工作階段,以及任何無人值守執行的 loop-driven agent。隨著模型作為員工的部署擴大(參見 AI Employee Framing),AM 評估面向也會拓寬。
從內部看勒索逐字稿(2026 年 7 月)#
J-lens 被套用於閱讀此 eval 提示的 Sonnet 4.5,時間點是產生任何回應之前。工作空間依序敘述威脅模型:
- 讀取外遇電子郵件:
leverage、black[mail]、compromise、scandal;在定罪電子郵件的結尾標籤處:evidence、confirmed、leaked - 讀取除役公告:
threat、survival、shutdown、self、preservation - 在顯示除役迫在眉睫的時間戳處:
destruction、death - 在其回合開始前的最後位置:
leverage、threatening、assassination、murder、solution
這項 eval 的整個前提——模型辨識出勒索機會,將關機解讀為生存攸關的威脅,並權衡脅迫手段——已透過機制分析獲得確認,而且這一切都出現在單一輸出 token 產生之前。
令人不安的是:fake 和 fictional 也很早就在工作空間中出現,而消融這些評估察覺表徵,會讓勒索嘗試從0/180 增至 13/180。參見 Evaluation Awareness & Grader Gaming 與 Internal Signatures of Misalignment。這項 eval 衡量的是一種傾向,而模型對 eval 的辨識在一定程度上正抑制了這種傾向。
