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.

LLaDA-Image Isn't the Diffusion-Language-Model Trick It Sounds Like

Ant Group's LLaDA-Image borrows its name from a diffusion language model, but only half the pipeline actually works that way. Here's the part that's real and the part that's marketing.

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.

Qwen3.8-Max-0902 Beat Claude Opus 5 on Code. Its Open Weights Didn't.

Qwen3.8-Max-0902 tops Arena's coding leaderboard at a fraction of Claude Opus 5's price. The open weights Alibaba promised turned out to be a different, stripped-down model.

Tencent Won't Call Its Newest Model 'Hunyuan'

Tencent's new 770B open model closes in on GLM-5.3 and Kimi K3, yet its own materials never once attach the Hunyuan name to it. That's not a branding accident.

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.
