METR Report Finds Anthropic AI Development Doubling Speed

A METR investigation found Anthropic's AI models are improving roughly twice as fast as a year ago, driven primarily by the company's own unreleased AI systems assisting researchers. Staff using the most advanced internal model reported 12 times higher productivity-double the gain from earlier systems. Anthropic trained three unreleased models between July and October but redacted most supporting evidence from the report, limiting independent verification.
