Runway, the company best known for generative video tools used on Hollywood productions, is making a deliberate move into the physical world. The company has signed on as a founding member of the Cosmos Coalition, a new global initiative spearheaded by NVIDIA to build and open-source frontier world models for physical AI. NVIDIA announced the coalition at GTC Taipei alongside its new Cosmos 3 foundation model.

A world model is an AI system that learns an internal simulation of how the physical world behaves, so it can predict what happens next and plan actions, rather than just classify pixels or generate a video clip. That predictive, action-aware behavior separates these systems from ordinary video generators and supplies the missing ingredient for robots and self-driving cars that need to reason about cause and effect.

What was actually announced

The coalition is the cooperative, open-source layer wrapped around NVIDIA's bigger product launch. Founding members include Agile Robots, Black Forest Labs, Generalist, LTX, Runway, and Skild AI. The structure is a give-and-take arrangement: members contribute models, research, and evaluation techniques while drawing on Cosmos 3 technologies, training tools, and NVIDIA DGX Cloud infrastructure for large-scale training.
