OpenAI's o3 is a frontier reasoning model that uses chain-of-thought inference to solve complex scientific, mathematical, and coding problems. It achieves top scores on GPQA Diamond, AIME, and SWE-bench, representing the state of the art in step-by-step reasoning. o3 trades higher inference latency for significantly deeper problem-solving capability.
