OpenAI launches new o3-mini model - here's how free ChatGPT users can try it

On the last day of OpenAI's 12 days of 'shipmas,' the company unveiled its latest models, o3 and o3-mini, which excel at reasoning and even outperform o1 on a series of benchmarks, including math and science. At launch, OpenAI CEO Sam Altman said o3 was slated to drop at the end of January, and today, the company made good on its promise.

On Friday, OpenAI released its o3-mini model, the most cost-efficient model in OpenAI's reasoning series, to the public. Until now, that series has been comprised of o1 and o1-mini. Like its predecessor, the model is particularly strong in science, math, and coding, according to the company. 

OpenAI o3-mini is now available in ChatGPT and the API.
Pro users will have unlimited access to o3-mini and Plus & Team users will have triple the rate limits (vs o1-mini).
