research @meta superintelligence. CS PhD @stanford. prev @openai, led the development of o3-mini and o1-mini.
The models are high again. We bring to you, o3 & o4-mini, our absolute best text & VISUAL reasoning models that truly manage to use any tools to solve hard tasks: canvas, browser, python, memory, ... & IMAGEGEN. The secret trick is to talk to the models in images🤫…
my jaw actually dropped today using the new os model sorry to hype but holy shit okay no more hype i promise
what year do you think an o3-mini level model will run on a phone?
It will be so good.
we are going to take a little more time with our open-weights model, i.e. expect it later this summer but not june. our research team did something unexpected and quite amazing and we think it will be very very worth the wait, but needs a bit longer.
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!
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…
i heard there's gonna be another mini ... ?
Yesterday was crazy so I missed my post but damn the 4.1s awesome. @michpokrass @jhyuxm @johnohallman @SuvanshSanjeev @StrongDuality and so many others did a phenomenal job. We’re truly horrible at naming but the secret trick is that the models with mini in their name are 🔥
Stay tuned
change of plans: we are going to release o3 and o4-mini after all, probably in a couple of weeks, and then do GPT-5 in a few months. there are a bunch of reasons for this, but the most exciting one is that we are going to be able to make GPT-5 much better than we originally…
o3-mini-high helps accelerate scientific discovery 💙 arxiv.org/abs/2503.23758
Excited to share our new study out in Nature Genetics @NatureGenet! 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…
📢 let us know what feature your want, we will train the model and ship the weights.
TL;DR: we are excited to release a powerful new open-weight language model with reasoning in the coming months, and we want to talk to devs about how to make it maximally useful: openai.com/open-model-fee… we are excited to make this a very, very good model! __ we are planning to…
Humanity's last exam gets doubled in two days from o3-mini to deep research, nice progress! 🚀🚀🚀
Very excited to finally share OpenAI's "deep research" model, which achieves twice the score of o3-mini on Humanity's Last Exam, and can even perform some tasks that would take PhD experts 10+ hours to do! A few thoughts on the implications: Deep research can be seen as a new…
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!
I will be on Reddit to answer your questions on o3-mini in 15min!
Reddit AMA with @sama, @markchen90, @kevinweil, @snsf, @michpokrass, and @ren_hongyu going live soon. reddit.com/r/OpenAI/comme…
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.
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!
