METR 报告：Anthropic 内部研发速度自 2025 年 10 月起加快 1.9 倍
Why we picked it
METR 给了新数据：Anthropic 用 AI 做研发后速度提升 1.9 倍，还曝光了内部 Model 3 和 4，想看递归自我改进证据的别错过。
METR 发布报告指出，Anthropic 因大量使用 AI 辅助研发，内部模型开发速度自 2025 年 10 月以来加快了 1.9 倍。报告图表将 Opus 5.5 归类为非前沿模型，并提及两个内部模型 Model 3 与 Model 4 在很短时间内取得明显改进。这份数据被外界视为模型递归自我改进趋势的一个信号。

ANTHROPIC 🔥: According to the latest report from METR, Anthropic is accelerating its internal AI model development, and this is attributable to Anthropic’s extensive use of AI for R&D
> Anthropic have accelerated 1.9x since October 2025.
> The chart categorizes Opus 5.5 as "non-frontier" and highlights internal models named Model 3 and Model 4, with substantial improvement achieved in a very short period.
