O3
O3 is a large language reasoning model developed by OpenAI, belonging to its reasoning model series. The model employs a reinforcement learning training paradigm with a focus on improving performance in complex logical reasoning, mathematical problem solving, and code generation tasks. O3 is designed to emphasize deep reasoning and multi-step inference capabilities, enabling it to handle highly challenging tasks in domains such as science, programming, and analysis that require structured reasoning. It is one of OpenAI's flagship models for high-performance reasoning scenarios.
