Anthropic's fourth Economic Index analyzes November 2025 conversations with Claude (mainly Sonnet 4.5) using five "economic primitives"—task complexity, skill level, purpose, AI autonomy, and success—to measure AI's real-world productivity effects. Key findings: higher-complexity tasks see larger speedups, success rates decline with task length, usage patterns vary by country and occupation, Claude more often augments than automates work, and adjusted estimates suggest AI could raise US labor productivity by roughly 1.0–1.2 percentage points per year when accounting for reliability.
