🗺️Towards A Roadmap of Video World Model🗺️
We conceptualize the progression of video generation through **four generations**, in which the core capabilities ultimately culminating in a world model.

Diffusion/Flow-based models can sample in 1-2 steps now 👍 But likelihood? Still requires 100-1000 NFEs (even for these fast models) 😭
We fix this! Introducing F2D2: simultaneous fast sampling AND fast likelihood via joint flow map distillation.

@giffmana There is no free lunch for sure.. But actually we can reduce time complexity with cost of space complexity(or more parallel computation), without sacrificing accuracy..
Tired to go back to the original papers again and again? Our monograph: a systematic and fundamental recipe you can rely on!
📘 We’re excited to release 《The Principles of Diffusion Models》— with @DrYangSong, @gimdong58085414, @mittu1204, and @StefanoErmon.
It traces the core ideas that shaped diffusion modeling and explains how today’s models work, why they work, and where they’re heading.
🧵You’ll find the link and a few highlights in the thread.
We’d love to hear your thoughts and join some discussions!
