Anthropic 发布 Claude Mythos Preview 对齐风险报告

原标题:Alignment Risk Update: Claude Mythos Preview

Anthropic 发布 Claude Mythos Preview 的对齐风险更新报告,威胁模型为模型利用组织内权限自主操纵系统或决策、抬升未来重大危害风险,例如篡改 AI 安全研究结果。报告称该模型已在 Anthropic 内部被大量用于编码、数据生成等智能体场景,总体风险评估为很低但高于以往模型,报告含删节内容并供内外部审阅者评议删节是否恰当。

为什么值得看

原文给出 Anthropic 对新模型滥用组织权限的威胁模型与总体风险评估,读者可据此了解其安全评估的判断口径。

information to a degree not justified by any commensurate public benefit. Redacted text has been made available to Anthropic’s internal Stress-Testing Team—alongside technical employees of Anthropic more broadly—and will be made available to some external reviewers. All such reviewers, internal and external, will be asked to comment on the appropriateness of the redactions. 4 2 Overview Threat model An AI model with access to powerful affordances within an organization could use its affordances [...] and further reduce the rate of concerning behavior occurring during training. Overall risk assessment Very low, but higher than for previous models. 5 3 Threat model The threat: If AI models are heavily used by powerful organizations—for example, to write a large amount of critical code—they might take advantage of this access to adversely influence decision-making, insert and exploit cybersecurity vulnerabilities, and take other actions that could significantly raise the risk of future harmful [...] use its affordances to autonomously exploit, manipulate, or tamper with that organization’s systems or decision-making in a way that raises the risk of future significantly harmful outcomes (e.g. by altering the results of AI safety research). Relevant AI model We focus our analysis on Claude Mythos Preview, our latest, most capable model. Current usage, capabilities and propensities Claude Mythos Preview is used heavily within Anthropic for coding, data generation, and other agentic use cases.

事件综述

Anthropic 发布 Claude Mythos Preview 对齐风险评估报告

2026 年 10 月 25 日,Anthropic 发布针对 Claude Mythos Preview 的对齐风险评估报告,指出若模型在组织内被大量用于编写关键代码等任务,可能利用权限自主操纵系统或决策。10 月 27 日的更新报告进一步描述威胁模型:模型利用组织内权限自主操纵系统或决策、抬升未来重大危害风险,例如篡改 AI 安全研究结果;并称该模型已在 Anthropic 内部被大量用于编码、数据生成等智能体场景。10 月 29 日的报道补充称该模型是公司最新、能力最强的模型,威胁还包括影响决策、植入并利用网络安全漏洞等。三份报道一致称:该模型总体风险评估为很低(very low),但高于以往模型;报告存在部分删节,删节文本已提供给内部压力测试团队并将开放给部分外部审阅者,审阅者将被邀请评估删节内容是否恰当。截至目前,报道均来自 Anthropic 官方博客,事件处于报告发布与删节内容评议阶段。
