METR审计：Anthropic模型加速或已触及自身预警阈值
原标题：METR finds Anthropic may have crossed its own AI acceleration warning threshold back in July
AI 摘要
非营利机构METR在获得Anthropic内部研究数据十一周访问权限后发布审计报告，发现Anthropic模型能力的提升速度自2025年10月以来约为此前的1.9倍，其中约80%的加速来自AI被用于公司自身研究。该加速可能已触及Anthropic《负责任扩展政策》中设定的预警阈值，METR认为该阈值或早在7月15日就已被跨越。但Anthropic对大部分关键证据行使了单方面删改权，并中途取消了算力分配审计，削弱了审计的透明度与说服力。

METR finds Anthropic may have crossed its own AI acceleration warning threshold back in July Nonprofit METR got eleven weeks of access to Anthropic's internal research data. Its finding: the rate at which Anthropic's models are improving has roughly doubled, and about 80 percent of that acceleration traces back to AI being used in the company's own research. Anthropic redacted the most important evidence, though. Whether AI is speeding up the development of better AI is considered a key early wa
