Runway AI Inc. today introduced Gen-4, a new artificial intelligence model that can generate videos based on natural language prompts.
New York-based Runway is backed by more than $230 million in funding from Nvidia Corp., Google LLC and other investors. The company launched its first AI video generator, Gen-1, in February 2023. The new Gen-4 model that debuted today marks the fourth iteration of the algorithm series.
Many video generation models are based on a neural network designed to generate images. The reason is that a video is a sequence of images, which means it can be generated one image at a time. This is usually done through a process called diffusion: a model starts with an image containing noise and gradually adds details over multiple steps.
