Anthropic is rapidly accelerating AI development amid slowdown calls, outside research group says

Chan and Huamani report on an analysis by the independent AI-evaluation group METR, which estimates that Anthropic's systems are advancing on its benchmark roughly twice as fast as a year earlier. The reporting draws on METR's analysis of Anthropic internal data and interviews, and notes the contrast with CEO Dario Amodei's public calls for the industry to slow down.

METR warns that AI-assisted research could compound progress, while emphasizing uncertainty about how much of the measured acceleration is attributable to AI and whether benchmark performance transfers to broader real-world capability.
