Median monthly messages per active user rose from 14 in 2023 to 36 in 2025, and the top 10% of users sent 63% of all prompts. Epoch AI's ChatGPT usage explorer draws on 8.3 million messages from 5,000 US YouGov panelists.
The share of US adults using AI at least 6 days a week rose from 8% in March 2026 to 19% in August 2026, according to Epoch AI/Ipsos polling.
Epoch AI/Ipsos survey: 67% of AI-using workers in computer, engineering, and science jobs use employer-provided AI.
One in five US workers say AI now does work they once handed to a coworker or contractor, per a new Epoch AI/Ipsos survey of 1,106 employed adults.
Household income of weekly AI users ranges from 80% earning $100K+ for Claude to 37% for Meta AI in the Epoch AI/Ipsos survey.
