Anthropic’s AI benchmark improvement rate has accelerated to about 1.9 times its earlier pace since October 2025, with most of the increase tied to internal research use, METR estimated. METR compared the improvement rate since October 2025 with the pace from March 2024 through October 2025. The comparison used a benchmark METR calls AECI. The review covered 11 weeks, from Aug. 12 to Oct. 29. METR examined confidential data, interviewed Anthropic staff and reviewed proprietary performance metrics. About 80% of the acceleration came from Anthropic’s internal use of its models for research and development.
