OpenAI o3-pro Released
OpenAI releases o3-pro to Pro users in ChatGPT and in its API, a version of o3 that thinks longer for the most reliable responses.
- OpenAI released o3-pro on 10 June 2025, 'a version of o3 designed to think longer and provide the most reliable responses', to Pro and Team users in ChatGPT and in the API, with Edu and Enterprise the following week; it replaced o1-pro in the model picker[1][3][4]
- It is part of the o3 family (o3-mini 31 January 2025, o3 16 April 2025); o3 is due to retire from ChatGPT on 26 August 2026 with the API unaffected[1][3]
Notable features
- o3-pro is an o-series reasoning model, trained with reinforcement learning, that uses more compute than o3 to think harder and give consistently better answers; in the API it runs only in the Responses API, and some requests can take several minutes[2]
- It takes text and image input and returns text, with a 200,000-token context window, up to 100,000 output tokens and a 1 June 2024 knowledge cutoff; API pricing is $20 per million input and $80 per million output tokens[2]
- Human testers preferred o3-pro over o3 across all queries (64%) and in every tested category, including programming (62.7%) and data analysis (64.3%)[4]
- Pass@1 results: AIME 2024 93% (o3 90%, o1-pro 86%), GPQA Diamond 84% (81%, 79%), Codeforces 2748 (2517, 1707); the stricter 4/4 reliability test gave AIME 90%, GPQA 76% and Codeforces 2301[4]
- Limitations at launch: temporary chats disabled, no image generation, no Canvas, and it can be slower than o1-pro in some cases[4]
