SadTalker

An older lightweight talking-head model: one photo plus audio becomes a video. Runs on weak hardware, but quality is noticeably below newer models.

The last open version came out in Jul 2023. The family has not been updated for a long time: the model still works, but do not expect fixes or new sizes.

Frequently asked questions

Can SadTalker be used in a commercial project?

Yes. License: Apache 2.0 (code), MIT on the HF card. It allows commercial use, but it is still worth having a lawyer review the license before launch.

What hardware does SadTalker need?

At minimum: Laptop or regular PC, up to 8 GB of VRAM — smaller 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 SadTalker support Russian?

Language does not matter for this model: it does not work with text.

Where can I download SadTalker and what does it cost?

The SadTalker 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.
