If you have a policy that uses diffusion/flow (e.g. diffusion VLA), you can run RL where the actor chooses the noise, which is then denoised by the policy to produce an action. This method, which we call diffusion steering (DSRL), leads to a remarkably efficient RL method! 🧵👇

We figured out how to train diffusion models with RL to generate images aligned with user goals! Our RL method gets ants to play chess and dolphins to ride bikes. Reward from powerful vision-language models (i.e., RL from AI feedback): https://t.co/5Mui7Wb8pB

Really excited to share what I've been working on with my colleagues at Physical Intelligence! We've developed a prototype robotic foundation model that can fold laundry, assemble a box, bus a table, and many other things. We've written a paper and blog post about it. 🧵👇

🔥 Top post I always found it puzzling how language models learn so much from next-token prediction, while video models learn so little from next frame prediction. Maybe it's because LLMs are actually brain scanners in disguise. Idle musings in my new blog post: 315K❤ 1.3K🔁 220
