METR estimates Anthropic's progress has doubled in pace on well-specified tasks
Independent evaluator METR published an assessment on 5 November 2026 estimating that Anthropic's capabilities on well-specified tasks are probably improving about twice as fast as between March 2024 and October 2025. The estimate carries substantial uncertainty.
METR reviewed internal data and interviewed employees from 12 August to 29 October. It judges that AI use in research probably explains most of the acceleration, without establishing definite causation. Researchers consider that actual acceleration could be closer to 1.3 or 3 times the earlier pace.
The report mainly describes assistance to researchers, rather than their complete replacement by autonomous systems. Anthropic redacted some evidence important to the findings, limiting public verification of the conclusions.
