AI rivals OpenAI and Anthropic shed new light on the AI revolution this week, releasing the first major data-driven studies on how their technology is used. The reports analyze millions of interactions to reveal a surprising truth: most people use AI for personal tasks, not their jobs, with 70% of ChatGPT conversations being non-work-related. According to a landmark study from OpenAI’s economic research team, published as a National Bureau of Economic Research (NBER) working paper, a staggering 70% of all consumer ChatGPT conversations as of July 2025 were not related to work. To measure this, the report introduces the Anthropic AI Usage Index (AUI), which compares a country’s share of Claude usage to its share of the global working-age population. Businesses are prioritizing model capability and the economic value generated by automating a task far more than the marginal cost of the API call itself.
