Open-source, locally runnable video generation from text — inspired by Sora, built for everyone.
Generate coherent, cinematic videos from natural language prompts — 100% offline, no cloud, no paywall.
OpenSora brings state-of-the-art text-to-video synthesis to your desktop. Trained on open datasets and built with transparent architecture, it empowers creators, researchers, and developers to explore the future of generative media — without dependency on closed APIs or corporate infrastructure.
While commercial video models remain closed, OpenSora is open by design:
- ✅ Fully local — runs on your machine (GPU or CPU)
- ✅ Open weights & training data — audit, fine-tune, extend
- ✅ Community-driven — no gatekeeping, no secrets
- ✅ Ethical by default — built with responsible AI principles
- ✅ Interoperable — integrates with Hugging Face, ComfyUI, and more
This is not just a model — it’s a movement toward open generative media.
- Text-to-video generation (2–16 seconds)
- Support for image + text conditioning (img2video)
- Resolution up to 1024×576 (progressive generation)
- Batch processing & seed control
- Export to MP4, GIF, or frame sequences
- Built-in safety filter (toggle on/off)
| Hardware | Resolution | Time |
|---|---|---|
| RTX 4090 | 512×512 | ~2 min |
| RTX 3090 | 384×384 | ~4 min |
| Apple M2 Max | 256×256 | ~6 min |
| CPU (16-core) | 256×256 | ~45 min |
Use --low-vram or --fp16 for memory-constrained systems.
OpenSora is more than code — it’s a commitment to:
- Open access to foundational generative models
- User sovereignty over data and output
- Global collaboration in AI development
- Education and research without barriers
We believe the future of AI must be open, local, and human-centered.
