Check out the latest open models. Absolutely no competitor of the same scale. Towards intelligence too cheap to meter.

gpt-oss is a big deal; it is a state-of-the-art open-weights reasoning model, with strong real-world performance comparable to o4-mini, that you can run locally on your own computer (or phone with the smaller size). We believe this is the best and most usable open model in the…

Today we release gpt-oss-120b and gpt-oss-20b—two open-weight LLMs that deliver strong performance and agentic tool use. Before release, we ran a first of its kind safety analysis where we fine-tuned the models to intentionally maximize their bio and cyber capabilities 🧵

gpt-oss is our new open-weight model family! the bigger one runs on a single GPU, you can run the small one on your laptop. Go install it right now, seriously! Telling your laptop to do something and watching it happen made me feel the AGI like nothing since ChatGPT.

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!


Which comes first? GPT6 or GTA6

GPT6 %53.8
GTA6 %46.2

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…

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🤫…

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…

📢 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!
