Anthropic's model benchmark gains estimated at 1.9 times their previous pace
Anthropic's October 2026 acceleration was about 80% due to AI, METR guesses, though the estimate is highly uncertain.
TLDR
METR estimates Anthropic's model benchmark scores have improved 1.9 times faster since October 2025. It says Anthropic has probably reached the 2x acceleration threshold in its Responsible Scaling Policy and may now be running as high as 3x. METR's guess that AI accounted for about 80% of the acceleration in October 2026 is highly uncertain.
