Good to have numbers. And, and as suspected, almost nobody was using o3 before, even if they paid for it. For most users, experiencing a Reasoner will be a surprise expansion of AI’s abilities & GPT-5 will appear to be a very big leap when auto-routes to the Thinking version.

the percentage of users using reasoning models each day is significantly increasing; for example, for free users we went from <1% to 7%, and for plus users from 7% to 24%. i expect use of reasoning to greatly increase over time, so rate limit increases are important.
Pretty clear the rollout was not aimed at power users, but at solving a different problem. For better or worse.

Even if GPT-5 did nothing besides switching people between o3 and 4o automatically, it would really transform most people’s view of AI. Very few people, even paying users, know that they should often switch to a more capable model, and when you show them o3, they are impressed.
