Runway
Video & Image Content Generation Tool
Runway is an AI platform for generative video and images, featuring Gen-4.5 for cinematic results and tools like Characters for real-time video agents.

What does Runway do?
Runway is an AI suite for building and generating video and image content, designed to bring cinematic motion quality, strong prompt adherence, and high visual fidelity to your creative workflow.
At the center is Gen-4.5, Runway’s generative video model focused on delivering realistic, cinematic outputs while giving you creative freedom and precise control over generation. It’s built to help you turn prompts into highly polished video creations.
Runway also supports real-time world-model experiences and specialized capabilities. With Runway Characters, you can build custom conversational video agent personas (appearance and visual style included) from a single image with no fine-tuning required. Runway’s General World Model research (GWM-1) is offered in variants for explorable environments, conversational avatars, and robotics.
Beyond the core models, Runway pairs product development with research and entertainment initiatives, spanning media and entertainment as well as robotics and autonomy—aiming to simulate the world by merging art and science.
