VIDEO GENERATION MODELS AS WORLD SIMULATORS

Summary from the TLDR Design newsletter

Video generation models could provide a promising way to build general-purpose simulators of the physical world. OpenAI combined text-conditional diffusion models with videos and images of varying lengths, resolutions, and aspect ratios to generate its outputs to create Sora. Based on a transformer architecture, Sora can create a minute of high-fidelity video using spacetime patches of video and image latent codes.
