OpenAI rolls out o3-pro model; CEO Sam Altman says open-weights model needs more time

OpenAI announced that its o3-pro model was rolling out to all ChatGPT Pro users, as well as the API.

OpenAI announced that its o3-pro model was rolling out to users, but CEO Sam Altman noted that an upcoming open weight model would not release this month.

OpenAI o3-pro will be available in the model picker for Pro and Team users, replacing OpenAI o1-pro. Enterprise and Edu users will get access after a week, per the company.

“In expert evaluations, reviewers consistently prefer OpenAI o3-pro over o3, highlighting its improved performance in key domains—including science, education, programming, data analysis, and writing. Reviewers also rated o3-pro consistently higher for clarity, comprehensiveness, instruction-following, and accuracy,” noted OpenAI.

OpenAI o3-pro can search the web, analyse files, process visual inputs, use Python, and personalise responses using memory, per the company.

“o3-pro is rolling out now for all chatgpt pro users and in the api. it is really smart! [I] didnt believe the win rates relative to o3 the first time i saw them,” posted OpenAI CEO Sam Altman on X on Wednesday (June 11, 2024).

However, a highly-anticipated open weights model that was set to be released will require more time, according to Altman.

“[W]e are going to take a little more time with our open-weights model, i.e. expect it later this summer but not june. [O]ur research team did something unexpected and quite amazing and we think it will be very very worth the wait, but needs a bit longer,” posted Altman on X on Wednesday.
