Skills, expertise, and work ethics follow a Pareto distribution with α >> 1 meaning that - in a professional context - some people are just exponentially better than others and they are rare. You want to work with and hire people who are exceptional. No compromises.

I was leading long context in Gemini for a while now, and today I’m proud to share what the team has achieved: over 1M context in a large-scale foundation model. Big shoutout to Denis Teplyashin and Machel Reid - without you this would not have happened! youtube.com/watch?v=wa0MT8…

Excited to share what Bill Peebles Tim Brooks and my team has been working on for the past year! Our text-to-video model Sora can generate videos of complex scenes up to a minute long. We're excited about making this step toward AI that can reason about the world like we do.

GPT-4o would not have happened without the vision, talent, conviction, and determination of Prafulla Dhariwal over a long period of time. that (along with the work of many others) led to what i hope will turn out to be a revolution in how we use computers.

I had the joy and the honor of being invited to give the Harvey Mudd College commencement address this year. In the vector space of all advice, I explore a 5-dimension subspace orthogonal to the “follow your dreams” vector. YouTube Link: youtu.be/W3I3kAg2J7w

An intuition for relative memory access times (scaled 10^10): Reg: 2 sec - Take from shelf Cache: 6½ min - Get from garage DDR Main: 20 min - Go to store DDR CXL: 1hr Far Mem: 8hr SSD: 6 days - Order online Spinning Disk (3ms): 1yr! Via Dylan Patel & SemiAnalysis

An intuition for relative memory access times (scaled 10^10):

Reg: 2 sec - Take from shelf

DDR CXL: 1hr
Far Mem: 8hr

Today OpenAI announced o3, its next-gen reasoning model. We've worked with OpenAI to test it on ARC-AGI, and we believe it represents a significant breakthrough in getting AI to adapt to novel tasks. It scores 75.7% on the semi-private eval in low-compute mode (for $20 per task

We launched a research preview of Operator today! It's a model built on top of GPT-4o that can control a browser — it is very early and will make mistakes, but it's a taste of things to come openai.com/index/introduc…

LLMs have complex joint beliefs about all sorts of quantities. And my postdoc James Requeima visualized them! In this thread we show LLM predictive distributions conditioned on data and free-form text. LLMs pick up on all kinds of subtle and unusual structure: 🧵

It's deeply concerning that one of the best AI researchers I've worked with, Kai, was denied a U.S. green card today. A Canadian who's lived and contributed here for 12 years now has to leave. We’re risking America’s AI leadership when we turn away talent like this.

Join us in making the next generation of agents both capable and safe! We think that agents will be a big part of how we interact with AI in the future, making it critical that we think carefully about how we build them.
