Last day of class of my brand-new course Physical Intelligence (lnkd.in/d9BMFG5d) at #UPenn. We concluded with a drone racing competition in the real world! I am really proud of all the students; I have no doubt that they will do great in the future!

it’s more like CES than any conference I’ve ever attended

neurips is a bit overwhelming and tiring. there are 20,000 attendees and hundreds of events mostly for recruiting. It’s strangely reminiscent of late stage college hackathon culture rather than Royal Society Meeting

The leaderboard Illusion is presented at #NeurIPS2025 today! Come learn why leaderboards mislead — and how we can fix them.

1/ Science is only as strong as the benchmarks it relies on. So how fair—and scientifically rigorous—is today’s most widely used evaluation benchmark? We took a deep dive into Chatbot Arena to find out. 🧵

Impromptu NeurIPS meetup: "representational convergence by the beach." We will meet at ballroom 20c (near lunch) 2pm Fri and walk over to Marina. Will chat about platonic reps, fractured reps, or anything else about where all these models are heading. Anyone is welcome to join!

I now run Meta's interpretability community-- 150+ researchers across FAIR, GenAI, & Reality Labs. Building our 2026 interp speaker series (w/ sessions on video models, world models, & causal discovery). At NeurIPS this week. If you're working on these areas, let's talk.

A NeurIPS/ICML tradition older than ChatGPT: the diffusion circle! Join us on the bayside terrace outside room 11 tomorrow (Friday) at 3:30PM in San Diego to talk about diffusion until the sun sets 🌄! The more the merrier, tell/tag your friends!

📢 Another #NeurIPS, another diffusion circle! Join us to talk about diffusion models on Friday Dec 5 at 3:30PM in San Diego! Bayside terrace outside room 11 (upstairs) ☀️🚢🌊 Please help spread the word, tell your friends! No slides, no talks, we just sit down and chat 🗣️

Yes I remember this from 10 years ago. My answers were not that great because I didn't get any sleep from the excitement. But it's interesting there was a question about scaling attention in a sub-linear way, which still is an important question and not fully answered.

The last thing you ever want to hear at the end of your talk

Ten years ago in 2015 we published a paper called End-to-End Memory Networks (arxiv.org/abs/1503.08895). Looking back, this paper had many of the ingredients of current LLMs. Our model was the first language model that completely replaced RNN with attention. It had dot-product…

Introducing the new fastest and most flexible view synthesis method: Radiance Meshes. RMs are volumetric triangle meshes that can be thrown into any game engine, rendered at ~200 FPS@1440p on a RTX4090, and edited using conventional tools. Here's a demo running on my desktop:

At NeurIPS? Come see our poster on learning a normalized energy model for photographic images - Friday 11am, poster 3700

What is the probability of an image? What do the highest and lowest probability images look like? Do natural images lie on a low-dimensional manifold? In a new preprint with @ZKadkhodaie @EeroSimoncelli, we develop a novel energy-based model in order to answer these questions: 🧵

🚨Google and UCSD just introduced Radiance Meshes, a new radiance field representation that produces watertight meshes and renders faster than 3DGS. Code and demos are available now. Code: github.com/half-potato/ra… Demos: half-potato.gitlab.io/rm/#demos
