Anthropic turned its AI on itself to measure its own economic impact. In a new study, the company used its Claude model to analyze one hundred thousand real, anonymized user conversations to estimate how much faster AI makes work. The findings are striking. Claude’s analysis suggests it reduces task completion time by approximately 80%, radically shortening jobs that would normally take 90 minutes. When extrapolated across the economy, these gains imply current AI models could increase US labor productivity growth by 1.8% annually for the next decade—a figure that would nearly double the nation’s recent growth rate.
