Skywork Open-Sources Matrix-Game 4.0, Pairing a Game Engine With a Real-Time Video Model

Skywork AI, the AI unit of Kunlun Tech, released Matrix-Game 4.0 on October 15 under the Apache-2.0 license. Gameplay, physics and player input stay inside an executable engine, while a causal few-step video model based on Wan2.2 5B Fun Control turns a low-poly view into detailed visuals. The company says it runs at about 83 fps with one denoising step on a single RTX 5090 and responds to a key press in under 0.15 seconds.

• On RTX 5090: ~83 fps with one denoising step, ~57 with two
