GWM Worlds 2 Creates Interactive Worlds Without a Game Engine

Runway announced GWM Worlds 2, its latest General World Model. The system produces continuous interactive simulations as a single 720p video stream at 24 fps with 48000 Hz audio. It responds to arbitrary inputs while users explore environments, subjects, visual styles, physical rules, and ambience that they define. Runway co-founders and researchers stated the model merges navigation, manipulation, and human interaction in one general action space and runs without a separate game engine. They noted it is already in use to evaluate vision-language models on real-world tasks. Additional posts from the company showed further prompting examples.
