Frequently asked questions
Can Open-Sora be used in a commercial project?
Yes. License: Apache 2.0. It allows commercial use, but it is still worth having a lawyer review the license before launch.
What hardware does Open-Sora need?
At minimum: One GPU with 16–80 GB — mid-size versions. Without a GPU the model is not practical. You can calculate the exact VRAM for your model size and context in the hardware calculator.
Does Open-Sora support Russian?
Language does not matter for this model: it does not work with text.
Where can I download Open-Sora and what does it cost?
The Open-Sora weights are open and free to download. You only pay for the hardware it runs on and for the setup. Source links are at the bottom of this page.
