OpenAI launches o3-pro model for ChatGPT Pro and Teams users

OpenAI has introduced o3-pro, an AI model that the company says outperforms its previous reasoning model, o3, which was launched in April.

In a post on X, OpenAI said, “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,” the company added.

Starting Wednesday, o3-pro will be available to ChatGPT Pro and Team users, replacing the o1-pro model. Enterprise and Education users will gain access the following week. The model is also live on OpenAI’s developer API.

The new model can search the web, analyse files, interpret visual inputs, run Python, personalise responses using memory, and much more.

On assessing o3’s key strengths, the company said, “We once again use our rigorous "4/4 reliability" evaluation, where a model is considered successful only if it correctly answers a question in all four attempts, not just one.”

However, there are currently some limitations with o3-pro:

• It does not support image generation or Canvas.
• Responses from o3-pro generally take longer compared to o1-pro.
• The temporary chats option in the model is currently disabled as OpenAI is working to fix a “technical issue”.
• According to TechCrunch, OpenAI’s AI-powered workspace feature isn’t supported by o3-pro yet.
