We've been pushing diffusion RL into new verifiable tasks. The surprise: lip-sync is one of them. The result is the highest-quality, fastest, and cheapest lip-sync model on the planet. Built on top of H3 Max by @fal

H3 Max Lip Sync is now live on fal. Upload one photo and one audio clip and get back a lip-synced video in seconds, with natural expression and movement, in any language. In our evals, H3 Max Lip Sync ranks #1# for both quality and speed, with a median generation time of just 11 seconds. Try it now on fal.

full runthrough of the boss fight in my game, this is all running in the BROWSER which feels crazy to say! tech stack: → @fal for generated assets → @threejs for rendering → Blender + Mixamo for rigging and animations → @suno for music and SFX → GPT-6-Astra for development

fal's Gorkem Yurtseven and Batuhan Taskaya on how faster-than-real-time generation unlocked continuous, interactive AI video: "One of our engineers, Rehan, started streaming a live stream of continuous generations of H3 Max from his laptop. He was doing some prompt tricks, trying to keep a coherent story, and then he started livestreaming that on Twitch." "Our ML team was essentially trying to take every single video model and apply these optimizations and tricks... You never could generate five seconds under five seconds. Once H3 Max unlocked it, the ML team was like, 'This is insane.'" "You can essentially stream infinitely. We capped it at an hour... I think it's the only model that can generate up to 60 minutes of continuous video that is action-controlled." "You can start with a prompt, say there's an office setting and someone is working, and then 30 seconds later it just imagines by itself. 30 seconds later, you can say, 'A woman walks in through the door.' It can take the prompt and reflect it immediately, which is the most fun part." "And the office is still the same office. The camera can pan back to the original person, and the original person is still there in the same state." @gorkem @isidentical @fal

One week until GenMedia Conference 2026. 500+ leaders across AI, media, entertainment and creativity. One day to talk about where generative media is going, and how it’s actually being used today. See you in San Francisco on September 24. Full list of speakers and topics is now live at

A year ago, LLMs could barely make a 3D sword. Now you can make that game you’ve had in your head with GPT-6-Astra and fal. I made this game in a very short time. If you want to play it or fork it and build on it: Play: Code:
