Runway · Interactive World Model

GWM Worlds 2

An autoregressive diffusion model for real-time interactive world simulation, producing continuous 720p 24fps video with generated 48kHz audio that responds to text actions and camera control through causal KV caching. New over the first GWM Worlds: audio, richer subject and scene control, and multiplayer with independent per-subject control, running indefinitely rather than to a preset duration. Labelled a research preview on Runway's platform only, with no parameter count, no named-baseline benchmarks and no open release.
