Runway is an AI-powered creative platform building General World Models — AI systems that can understand, generate, and simulate visual worlds. Its flagship tools include Gen-4.5, a state-of-the-art video generation model that turns text prompts into cinematic, high-fidelity video; GWM-1, a real-time world simulation engine for explorable environments and robotic interactions; and Characters, an API for creating fully autonomous, conversational video agents from a single image. Used by filmmakers, studios, architects, and enterprises like Lionsgate and NVIDIA, Runway sits at the intersection of art and science — giving creators the power to produce professional-quality visual content without traditional production pipelines.
