Anthropic’s January 2026 Economic Index report added measures such as “task success,” which “measures Claude’s assessment of whether Claude completes tasks successfully”; for Claude.ai the classifiers were checked against a human researcher on a small set of transcripts for which users had given feedback, and the report calls them “directionally accurate”; it found augmentation rising to 52% of Claude.ai conversations.
