README EXCERPT

Open-Sora: Democratizing Efficient Video Production for All We design and implement Open-Sora , an initiative dedicated to efficiently producing high-quality video. We hope to make the model, tools and all details accessible to all. By embracing open-source principles, Open-Sora not only democratizes access to advanced video generation techniques, but also offers a streamlined and user-friendly platform that simplifies the complexities of video generation. With Open-Sora, our goal is to foster innovation, creativity, and inclusivity within the field of content creation. 🎬 For a professional AI video-generation product, try Video Ocean — powered by a superior model. 📰 News - [2025.03.12] 🔥 We released Open-Sora 2.0 (11B). 🎬 11B model achieves on-par performance with 11B HunyuanVideo & 30B Step-Video on 📐VBench & 📊Human Preference. 🛠️ Fully open-source: checkpoints and training codes for training with only $200K .
