Anthropic Education Report: The AI Fluency Index
Summary
Anthropic's AI Fluency Index assesses how people fluently collaborate with AI, using the 4D AI Fluency Framework to track 11 observable behaviors across 9,830 Claude conversations in January 2026. The findings show a strong link between iteration/refinement and fluency, while producing artifacts correlates with less critical evaluation. The report outlines practical improvement areas, discusses limitations, and sketches future research directions to broaden understanding of AI fluency beyond Claude.ai.
