- R · What Makes It Special
- OpenAI's o3-pro (June 10, 2025), a version of its o3 reasoning model that uses more compute to think longer and give the most reliable responses; it replaced o1-pro for ChatGPT Pro and Team users, with Enterprise and Edu a week later, and expert reviewers preferred it to o3 in every tested category. In the API it runs only through the Responses API, with a 200K-token context and 100K output, at $20/$80 per million tokens; OpenAI shuts it down December 11, 2026, recommending GPT-5.6 Sol.
