OpenAI Unveils o3, a Smarter AI Model With Improved Reasoning Skills

OpenAI has unveiled a new AI model that it says takes longer to solve problems but gets better results, following Google's similar announcement a day earlier. The model, called o3, replaces o1 from September and spends extra time working through questions that need step-by-step reasoning.
It scores three times higher than o1 on ARC-AGI, a test measuring how well AI handles complex math and logic problems it hasn't seen before. "This is the beginning of the next phase of AI," CEO Sam Altman said
