OpenAI launches o3-pro, a version of o3 that thinks longer for more reliable answers, available to ChatGPT Pro and Team subscribers and in the API, alongside an o3 price cut.

What changes

  • Replaces o1-pro in ChatGPT; same tools as o3 (web search, file analysis, vision, Python, memory).
  • Expert reviewers prefer it to o3 in every category tested, notably science, education, programming and business.
  • Evaluated with a "4/4" reliability test: the model must answer correctly in all four attempts.
  • Responses often take several minutes, so it is best reserved for difficult questions.
  • The price of o3 in the API is cut by 80% the same day.
