METR, an AI safety research organization, published a report on Thursday, November 5, 2026, after an 11-week investigation inside Anthropic. It found the company is using AI to build more powerful AI, with its models improving roughly twice as quickly as a year ago. The report evaluates Anthropic's AI research and development practices and shows little sign of slowing. Researchers quoted by The Verge say the findings are alarming, as the pace of AI self-improvement raises questions about oversight.
