AI company Runway has announced what it calls its first world model, GWM-1. It’s a significant step in a new direction for a company that has made its name primarily on video generation, and it’s part of a wider gold rush to build a new frontier of models as large language models and image and video generation move into a refinement phase, no longer an untapped frontier.

GWM-1 is a blanket term for a trio of autoregression models, each built on top Runway’s Gen-4.5 text-to-video generation model and then post-trained with domain-specific data for different kinds of applications. Here’s what each does.

GWM Worlds

GWM Worlds offers an interface for digital environment exploration with real-time user input that affects the generation of coming frames, which Runway suggests can remain consistent and coherent “across long sequences of movement.”
