How Does Sora AI Work?

Sora’s technology is built upon the foundation of DALL-E 3 technology. Described by OpenAI as a diffusion transformer, Sora AI employs a denoising latent diffusion model with a single Transformer serving as the denoiser. In the process, a video is created within the latent space by denoising 3D “patches,” and subsequently, it is converted to standard space through a video decompressor. To enhance training data, re-captioning involves a video-to-text model that generates detailed captions for videos.

The model’s architecture comprises a visual encoder, diffusion Transformer, and visual decoder.

  1. The visual encoder compresses videos into a latent space, representing reduced dimensionality.
  2. The diffusion Transformer generates sequences of visual patches based on user prompts, and the visual decoder reverses the encoding, producing the final video.
