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!

Comment highlights

Congratulations on the launch of OpenAI o3-mini! The focus on cost-effective reasoning is commendable. How do you envision users integrating the function calling feature to enhance their existing workflows in STEM applications?

Congratulations on the launch of OpenAI o3-mini! It's great to see advancements in cost-effective reasoning models for STEM applications. What specific optimizations have been made to enhance speed and performance in real-time coding tasks compared to previous models?

we'll test this in the following weeks for ActorDO AI Assistant. Wonder how it deals with intent detection.

It keeps generating incomplete text to answer simple questions after overthinking for about 10 seconds. And its "thought process" is just a string of buzzwords—"I'm thinking, now I'm gathering, I speculate that, I'm emphasizing, I suspect that". Honestly, R1 (which is basically free) puts this to shame. C'mon OpenAI get this right I'm rooting for you guys

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.

Impressive from you guys. Though there's a limit. How do you plan to compete with deepseek ad other models that have no limit to their free users? We're looking forward to seeing Open AI stand for "open AI". Congratulations to you guys for this launch

its awesome. but deeply sad it doesnt show the whole reasoning process like deepseek r1. this wont go viral

Making AI more affordable and functional is a sign of AI being adopted by various industries. Excited to witness the future!
