OpenAI has introduced o3-pro, its most advanced AI model to date, designed to enhance reasoning capabilities in areas such as physics, math, and coding. This model is available to ChatGPT Pro and Team users, replacing the previous o1-pro model, with Enterprise and Edu users gaining access the following week. O3-pro is also accessible via OpenAI’s developer API, priced at $20 per million input tokens and $80 per million output tokens. Despite some limitations, such as longer response times and the inability to generate images, o3-pro is praised for its clarity, comprehensiveness, and accuracy, outperforming competitors like Google’s Gemini 2.5 Pro and Anthropic’s Claude 4 Opus in key benchmarks.

O3-pro offers advanced features, including web searching, file analysis, and Python usage, although temporary chats and Canvas support are currently unavailable due to technical issues. OpenAI highlights that expert evaluations consistently favor o3-pro over its predecessor, o3, particularly in domains like science, education, and business. The model's enhanced performance in AI benchmarks underscores its capabilities, making it a significant upgrade for users seeking advanced reasoning and problem-solving tools.
