OpenAI · 2024-09-12
o1-preview is OpenAI's September 2024 early-access release of its o1 reasoning model series, made available to users while the full o1 was still in development. It uses chain-of-thought reinforcement learning to spend more time "thinking" before responding, yielding substantially stronger performance on complex reasoning, coding, and math tasks compared to GPT-4o.
