big news: the free tier of chatgpt is going to get o3-mini! (and the plus tier will get tons of o3-mini usage)

I have been playing R1 for a while, it's very impressive in Chinese. Congrats to the DeepSeek team!

o3-mini's intelligence x speed combo is incredible, idk what to say other than just try it and see for yourself. This took 8 seconds, how long would it take you?

o3-mini is a remarkable model. Somehow it has *grokked arxiv* in a way that no other model on the planet has, turning it into a valuable research partner! Below is a deceitfully simple question that confuses *all* other models but where o3-mini gives an extremely useful answer!

o3-mini is out! smart, fast model. available in ChatGPT and API. it can search the web, and it shows its thinking. available to free-tier users! click the "reason" button. with ChatGPT plus, you can select "o3-mini-high", which thinks harder and gives better answers.

I will be on Reddit to answer your questions on o3-mini in 15min!

If you are a researcher, you should talk to o3-mini about your research.

We released o3-mini today! Everyone can use it for free. It reasons hard, reasons fast, searches the web, and most importantly, knows research. Ask the model hard questions and brainstorm with it!

Humanity's last exam gets doubled in two days from o3-mini to deep research, nice progress! 🚀🚀🚀

📢 let us know what feature your want, we will train the model and ship the weights.

Excited to share our new study out in Nature Genetics Nature Genetics! We introduce MESA, a spatial omics framework that draws inspiration from ecology and integrates multiomics data to study the spatial architecture of tissues in health and disease. Building on the analogy between

Stay tuned

i heard there's gonna be another mini ... ?

I’m absolutely blown away by OpenAI’s new o3 model! I’ve had early access and haven’t put it down for days. This release feels like the milestone we experienced with o1-preview and o1-pro, but smarter and more reliable in every way, it truly cranks everything up to eleven! In

Which comes first? GPT6 or GTA6

very grateful to all the developers who spent time with us telling us what they wanted from an open-weights model. the feedback was useful and unexpected, but all doable. i think we will ship something extraordinary!

It will be so good.
