Abstract: Recent advances in interactive video generations have demonstrated diffusion
model's potential as world models by capturing complex physical dynamics and
interactive behaviors. However, existing interactive world models depend on
bidirectional attention and lengthy inference steps, severely limiting
real-time performance. Consequently, they are hard to simulate real-world
dynamics, where outcomes must update instantaneously based on historical
context and current actions. To address this, we present Matrix-Game 2.0, an
interactive world model generates long videos on-the-fly via few-step
auto-regressive diffusion. Our framework consists of three key components: (1)
A scalable data production pipeline for Unreal Engine and GTA5 environments to
effectively produce massive amounts (about 1200 hours) of video data with
diverse interaction annotations; (2) An action injection module that enables
frame-level mouse and keyboard inputs as interactive conditions; (3) A few-step
distillation based on the casual architecture for real-time and streaming video
generation. Matrix Game 2.0 can generate high-quality minute-level videos
across diverse scenes at an ultra-fast speed of 25 FPS. We open-source our
model weights and codebase to advance research in interactive world modeling.
