OpenAI announced the launch of its new AI model, o3-mini, which it said was the “newest, most cost-efficient model” in its reasoning series and optimised for STEM reasoning.

While OpenAI’s o1 focuses on broader general knowledge, o3-mini caters to users who need more speed and precision for technical tasks.

“Similar to its OpenAI o1 predecessor, OpenAI o3-mini has been optimized for STEM reasoning. o3-mini with medium reasoning effort matches o1’s performance in math, coding, and science, while delivering faster responses,” said OpenAI in a blog post.

“Evaluations by expert testers showed that o3-mini produces more accurate and clearer answers, with stronger reasoning abilities, than OpenAI o1-mini,” the company added, noting that OpenAI o3-mini delivered faster performance as well as improved efficiency. 

o3-mini is accessible immediately to ChatGPT Plus, Team, and Pro users, while Enterprise access will arrive this month. o3-mini will also replace OpenAI o1-mini in the model picker.
