Our team compiled data from 14 unique sources to estimate ChatGPT’s usage as of April 2025. Because each source had a different methodology for calculating usage, our model used a weighted average of all sources, with the weights based on the source’s longevity, credibility, and reputed accuracy. Further, we applied our model to the trailing 12 months to create a picture of the last year’s ChatGPT usage trend.
