Skywork open-sources Matrix-Game 4.0, a game engine paired with a real-time video model

Skywork AI released Matrix-Game 4.0 on October 15 under the Apache-2.0 license, with inference code on GitHub and model weights on Hugging Face.

The system keeps gameplay and physics in an executable engine, while a causal video model renders the visuals, and the company claims it runs in real time on one RTX 5090 at about 83 frames per second with one denoising step.

GitHub documentation lists roughly 38 to 39 frames per second for the shooter scenes, and the demos output at 480p.
