We solved Navier-Stokes! Many of my colleagues left their fields because they believed that working on AI would be the fastest way to solve their fields' grand challenges. It's surreal to see the first of those challenges fall and to watch a future we believed in become real.

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem

It’s hard to overstate @michpokrass's impact on our consumer products. ChatGPT has had a rebirth under her leadership, and a lot of what we've built has been driven by her vision and conviction. Really grateful to work with her!

“we cannot rule out that de-identified data derived from their usage of our products helped improve our models.” i mean props to them for straight coming clean. (so far the proof looks more along the lines of another euler blowup proof we had, off of whose ansatz naming we were

Agree with @JensenHuang: we’re entering the AGI era. The AGI era must also be the alignment era. We need to teach AI to love humanity and train AI monitors as capable as the AIs they supervise. Said best by @merettm in this thoughtful, sobering piece: openai.com/index/an-alien…

GPT-6 Astra is here! This is a big moment for our research team - years of work on pretraining, reinforcement learning, and post-training have come together in our most capable and aligned model yet. It can build and test software, work across apps on your computer, and even help

This is GPT-6 Astra. Anything you can do on a computer, Astra can do for you. Fast.
