About o3-mini

"OpenAI's efficient reasoning model with adjustable thinking depth for complex problems"

o3-mini is OpenAI's efficient reasoning model that delivers o3-level thinking capability at a significantly lower cost and latency, making advanced chain-of-thought reasoning accessible for everyday use. By applying extended reasoning selectively with adjustable thinking effort levels (low, medium, high), o3-mini can tackle complex coding, mathematical, and logical problems that simpler models struggle with, while maintaining fast response times for straightforward queries. With strong performance on competitive programming benchmarks and STEM problems, o3-mini is ideal for technical workflows requiring reliable reasoning.
