What It Is

Primary content is rendered into static HTML.

Open-Sora is an open research and engineering project from the HPC-AI/Colossal-AI ecosystem. It provides code, models, and training/inference workflows for open video generation.

It is not a consumer product, but it is important for open-source evaluation because it provides a public baseline and implementation path for researchers and developers.

Key Features

  • Open frameworkThe project provides open code and model resources for video generation research.Source
  • Primary source-backed profileOpen-Sora has an official source, repository, paper, or model card attached for verification.Source
  • Open/self-hosted access pathOpen-Sora can be evaluated through open code, weights, or model-card resources when license terms allow.Source

Version Progress

  • 2024 / partial / partialOpen-Sora 1.xEarly open Sora-style video generation project releases.
