Runway is an AI video generation platform developed by Runway AI, Inc. that enables creators to produce and edit video content from text prompts, images, and existing footage. Its Gen-3 Alpha model, launched in June 2024, introduced significantly improved motion and physics simulation, and subsequent Gen-4 and Gen-4.5 releases ranked above Sora 2 Pro on Artificial Analysis video generation leaderboards. Runway offers a tiered subscription model and remains one of the most widely adopted commercial AI video tools.

Founded in 2018 and headquartered in New York City, Runway pioneered accessible generative AI for creative professionals with its earlier Gen-1 and Gen-2 models. The platform supports text-to-video, image-to-video, video-to-video, motion brush, and advanced editing features including inpainting, outpainting, and style transfer. Runway has been used in feature film and television production workflows and maintains integrations with major creative tools.
