METR Says Anthropic May Have Crossed Its AI Acceleration Warning Threshold in July
METR finds Anthropic may have crossed its own AI acceleration warning threshold back in July
What happened
METR estimates that Anthropic's models have improved about 1.9 times faster since October 2025, with roughly 80 percent of the acceleration attributed to AI use in the company's research. The nonprofit says the estimate is imprecise, and Anthropic redacted much of the evidence it considered most informative. METR says the warning threshold may have been crossed on July 15, 2026.

METR’s estimates, internal dissent, and Anthropic’s redactions show how the evidence shapes claims about AI-driven research acceleration and its warning threshold.
