Skywork AI has released Matrix-Game 4.0 with inference code, a browser demonstration and three playable game sources. An executable engine handles rules, physics and player input, while a video model turns low-poly frames into detailed images. Scene-specific weights and assets accompany the code. The release separates the game’s changing state from its neural rendering.
Skywork AI, the developer of the Matrix-Game interactive-world model series, released version 4.0 on October 15. Its executable game engine controls gameplay rules, physics and player input, while a video model turns the engine’s low-poly frames into detailed visuals. The arrangement separates the game’s state from the neural rendering that presents it.[1], [2]
The release includes inference code, a browser demonstration and source code for three playable games. Medieval Castle and Ancient Egypt are third-person shooting scenes, while City Racing is a driving game. Each has its own model weights, with weights and game assets supplied through Hugging Face. The video model generates successive chunks conditioned on the engine’s RGB images and text prompts.[1]
Matrix-Game 4.0 is released under Apache-2.0, while third-party components and assets retain their own terms. Earlier implementations stay in their original directories with existing licenses. The series began in May 2025 and followed with a second version in August 2025. Its March release of version 3.0 focused on real-time interaction with long-horizon memory. The new documentation provides separate paths for installation, resource downloads, offline rendering and the browser demonstration.[1]
