Runway
Runway develops generative AI models and tools that create and edit video and images, and is now also building world models for simulation and robotics.
What Runway does
Runway trains its own video and image generation models, such as Gen-4.5 and Aleph, and offers them in a web and mobile app for filmmakers, agencies, brands and individual creators. Users can generate clips from text or images, edit existing footage, add voice and music, and build ad campaigns or small creative apps. The company also sells API access and has extended its research into general world models aimed at simulation and robot training.
