ChatGPT o3-pro: Sam Altman’s OpenAI launches its most powerful AI model yet

OpenAI has introduced o3-pro, a new AI model it describes as its most advanced to date. Built on the foundation of the o3 model, which debuted earlier this year, o3-pro represents a significant leap in performance. Unlike traditional AI systems, reasoning-based models like o3-pro tackle problems methodically, step by step, allowing for greater accuracy and consistency—particularly in complex areas such as mathematics, physics, and programming.
