Independent evaluator METR estimates that Anthropic is currently advancing the capabilities of its models roughly twice as fast as it previously did, with benchmark scores improving 1.9x faster since October 2025. METR attributes a large share of this acceleration to the use of AI itself, estimating that AI may account for around 80% of the current acceleration, though it notes that this figure is highly uncertain.

Independent evaluator METR estimates that Anthropic is currently advancing the capabilities of its models roughly twice as fast as it used to, and that the use of AI itself is driving a large part of this acceleration.
Key Findings
- Faster benchmark gains: METR found that Anthropic's model benchmark scores have improved 1.9x faster since October 2025.
- AI as a driver: METR estimates that AI may account for around 80% of the current acceleration, though that estimate is highly uncertain.
