METR estimates Anthropic’s capabilities now improve at about twice its 2024 to 2025 pace

Source: METRAlso reported by CNA, The Information

METR ran a high-access evaluation at Anthropic from 12 August to 29 October 2026 to assess whether AI is accelerating AI R&D. It estimates that Anthropic is likely improving its models on well-specified tasks at around twice the rate of March 2024 to October 2025, and that a majority, perhaps about 80%, of the current acceleration is due to AI, with high uncertainty. METR reports no clear bottlenecks that would prevent further progress over the next 12 months, but says its understanding of the bottlenecks changed several times during the assessment.

Why it matters

Anthropic redacted a majority of the evidence METR found most informative, so the public has to rely on METR’s judgment much more than would be ideal.
