Skywork open-sources Matrix-Game 4.0

An executable game engine keeps the gameplay, physics and input, while a causal video model re-renders its low-poly frames into detailed visuals. The v4 code is Apache-2.0, as are the scene weights and game assets on Hugging Face; third-party parts keep their own licences. Three demo scenes, with single-GPU inference paths for A100, RTX 5090, 5080 and 5070 Ti.
