OpenAI begins releasing its next generation of reasoning models with o3-mini

Developers can access o3-mini through an API and can select between three levels of reasoning intensity.

OpenAI released its newest reasoning model, called o3-mini, on Friday. OpenAI says the model delivers more intelligence than OpenAI’s first small reasoning model, o1-mini, while maintaining o1-mini’s low price and speed. The company says o3-mini excels in science, math, and coding problems.
