VideoDeltaNet Is Faster Than Playback. It Also Needs Eight B200 GPUs.

VideoDeltaNet turns MiniMax H3 into a model that renders a 14-second clip in 11.23 seconds. The catch: that number needs eight B200 GPUs, and on a single consumer card an older method still wins.

Runway Says GWM Worlds 2 Trains AI Agents. The Evidence Is One Robot and Two Flags.

GWM Worlds 2 streams real-time 720p worlds with synced audio and pitches itself as agent-training infrastructure. The actual training evidence is one demo.

SolarWM Trains on Five-Second Clips, Then Runs for an Hour Without Breaking

SolarWM trains video world models on five-second clips, then runs stable rollouts for hours by fixing a training mismatch instead of scaling up the model.

MiniMax's H3 Video Model Gets a 14x Speedup, Trained on Footage Nobody Ever Filmed

FastH3 cuts MiniMax H3 from 49 sampling steps to 4 using training data the model generated for itself, no real footage involved. The 14x number is real, on 8 B200s. I checked what a 4090 actually gets you, and what the license quietly locks out.

AI World Models Have an Amnesia Problem. This One Hired a Programmer to Fix It.

Code World Model splits the job in two: a coding agent tracks what's actually happening, a fine-tuned MiniMax H3 renders it. It's a clean fix for AI world models' memory problem, on paper.
