Anthropic Economic Index: Insights from Claude 3.7 Sonnet

Summary

Anthropic’s second Economic Index report examines how Claude.ai usage changed after Claude 3.7 Sonnet launched, using 1 million anonymized Free and Pro conversations from the following 11 days. Clio maps conversations to 17,000 tasks in the U.S. Department of Labor’s O*NET database, enabling comparisons across occupations and interaction modes, while the report also introduces a 630-category bottom-up taxonomy. Coding, education, and science usage increased modestly, and extended thinking appeared most often in technical and creative work, including computer science research, software development, multimedia art, and video game design. Augmentation remained 57% of usage, learning interactions rose from about 23% to 28%, and the report releases task- and occupation-level datasets covering thinking mode and augmentation-versus-automation patterns.
