Anthropic Economic Index report: Economic primitives

This Anthropic Economic Index report analyzes AI usage patterns of the language model, Claude, in November 2025, just before the release of Opus 4.5. It introduces new metrics, called economic primitives, to provide insights into five dimensions of AI use: task complexity, human and AI skills, work, coursework or personal use, AI's level of autonomy, and task success. The report finds that AI usage is geographically concentrated, with higher-income countries using AI more collaboratively while lower-income countries focus on coursework and specific applications. It also shows that AI tends to be used more, and provides greater productivity boosts, on tasks that require higher education. The report suggests that the impact of AI on the economy is unlikely to be uniform, and that the labor market implications for different workers will hinge on how reliable AI tools are for their most central tasks.
