OpenAI is releasing two new AI reasoning models today: o3, which the company calls its “most powerful reasoning model,” and o4-mini, which is a smaller and faster model that “achieves remarkable performance for its size and cost,” according to a blog post.

OpenAI o3, the developer's most advanced generative AI reasoning model yet, is here. This new family of models promises strong performance in coding, math, science and visual understanding, the company said in a press release on Wednesday.

OpenAI is rolling out a pair of new artificial intelligence models that mimic the process of human reasoning to field more complicated coding questions and visual tasks, the latest in a flurry of releases from the company to fend off renewed competition in the US and China.
