# Wan Face Swap

> Asynchronous face swap model that transfers a source face onto a target image while preserving the target pose, lighting, and background.

Wan Face Swap replaces the face in a target image with a face supplied by a second source image.

The model preserves the target composition, pose, lighting, and background while adapting the source identity to the scene.

In GENGEN, Wan Face Swap uses a dedicated asynchronous image task endpoint and returns `wanfaceswap:<remote_id>` public task IDs.

## Model ID

```text theme={"dark"}
wan-face-swap
```

Pass this exact public ID in the top-level `model` field. Do not substitute an upstream provider alias.
