Summary

Introduces five “economic primitives” — task complexity, human/AI skill levels, use case type, AI autonomy, and task success rates — classified by Claude itself across 1M Claude.ai conversations and 1M API transcripts from November 2025. 70% success rate on high school-level tasks; 12x time savings on college-level vs. 9x for simpler work. Adjusting for success rates cuts implied annual productivity gains from 1.8 to ~1.0 percentage points.

Implications

This is the Economic Index measurement infrastructure thread maturing — moving from “what tasks does AI touch” to “does it actually succeed.” The success rate adjustment is the critical methodological contribution: raw task coverage overstates real productivity gain by ~80%. The geographic concentration finding (usage strongly predicted by GDP per capita, US state convergence in 2-5 years) is important for understanding who benefits and when. The 12x speedup on complex tasks is a product of niche selection — watch whether that metric holds or regresses as Claude deploys into broader user populations.
