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 🧵
Hongyu Ren retweeted
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.

my jaw actually dropped today using the new os model sorry to hype but holy shit okay no more hype i promise
Hongyu Ren retweeted
what year do you think an o3-mini level model will run on a phone?
It will be so good.
Hongyu Ren retweeted
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!
Hongyu Ren retweeted
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 ... ?
Stay tuned
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.

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

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