So excited to see the o3-mini finally launch! It's the newest, most cost-efficient model of OpenAI in the reasoning series, available in ChatGPT and the API. o3-mini advances the boundaries of what small models can achieve, delivering exceptional STEM capabilities—with particular strength in science, math, and coding—all while maintaining the low cost and reduced latency of o1-mini. Now you can click 'Reason' button on ChatGPT and let the thinking magic work :D Try it out!

@maxcomx Maybe that was temporary? When I tried it, it did show it's chain of reasoning. Wonderful to look at!

I'm very happy with this new model, and I've already started using it in my language learning platform Elon.io It appears to be doing very well at generating language courses, while my costs are greatly reduced.

o3-mini has been super helpful for our ODRR tool, it produced absolutely on-point results most of the times, we tried other models, but o3-mini in the end was the most cost effective and accurate model for our usecase.
