Runway offers an AI video generation platform that takes text prompts, images, or existing video clips as input and produces short synthetic video clips. The platform's current flagship model, Gen-4.5, is available to all paid subscribers worldwide.

Runway's generative video models have progressed through several generations: Gen-2 (June 2023), Gen-3 Alpha (June 2024), Gen-4 (March 2025), and Gen-4.5 (December 2025). Gen-4.5 supports text-to-video, image-to-video, and video-to-video generation modes, producing clips at up to 720p resolution at 24 fps with optional 4K upscaling on higher-tier plans. The model is also integrated into Adobe Firefly via a multi-year partnership announced in December 2025.
