OpenAI’s New o3 Model Won’t Come Cheap. Why Microsoft Is Paying Close Attention.

OpenAI has introduced its latest AI models, o3 and o3-mini, marking a significant advancement in artificial intelligence reasoning capabilities. These models are designed to tackle complex tasks requiring step-by-step logical processes, building upon the foundation laid by their predecessor, o1.

Key Features and Enhancements:

• Advanced Reasoning: The o3 models employ a "private chain of thought" methodology, allowing them to deliberate internally before generating responses. This approach enhances their ability to handle intricate problems in coding, mathematics, and science.

• Performance Metrics: In evaluations, o3 has demonstrated superior performance compared to o1. For instance, on the SWE-bench Verified benchmark, which assesses the ability to resolve real GitHub issues, o3 achieved a score of 71.7%, surpassing o1's 48.9%. Additionally, on the ARC-AGI benchmark, which tests AI's capacity to manage novel and challenging mathematical and logical problems, o3 attained three times the accuracy of o1.
