Runway

Runway Gen-4.5 represents the latest milestone in a lineage that began with Gen-1, the first publicly available video generation model released by Runway roughly two years prior. The model has been built on a foundation of continuous advancement in both base model capabilities and controllability features, including in-context generation. Running on NVIDIA Hopper and Blackwell GPUs, Gen-4.5 is designed to deliver state-of-the-art motion quality, prompt adherence, and visual fidelity, producing cinematic and highly realistic outputs that provide precise creative control over every aspect of generation.

The model benefits from significant advances in both pre-training data efficiency and post-training techniques that set new standards for dynamic, controllable video generation. Its API access enables professional video production workflows, serving filmmakers, advertisers, and media companies that require high-quality cinematic content generation from text and image inputs. Runway has positioned Gen-4.5 as the world's top-rated video model, with the platform also offering complementary capabilities like image generation and audio generation, reflecting a broader creative AI toolkit beyond video alone.
