A paper by researchers affiliated with OpenAI, Duke and Harvard reports more than 700 million weekly active accounts on ChatGPT consumer plans by the end of July 2025. The authors caution that account totals can exceed the number of distinct people. Their analysis of sampled consumer conversations found that more than 70% of messages were unrelated to paid work; “practical guidance,” information seeking and writing were the leading topics. This suggests that the service’s reach is felt in everyday learning, information and communication, as well as in offices. The study uses OpenAI product data and automated message classifications, so it does not independently establish how accurate answers were or how much time users saved. In November 2025, OpenAI said more than one million organizations around the world were paying to use its business products or models through its developer platform. That company-defined customer count indicates organizational adoption, not proof that every deployment improved productivity or outcomes.
