# Luma UNI-1 Image Edit Node

This node edits an existing image using a text prompt, powered by the Luma UNI-1 model. It takes a source image and a description of the desired change, then generates a new edited version of the image.

## Inputs

| Parameter | Description | Data Type | Required | Range |
|-----------|-------------|-----------|----------|-------|
| `source` | Source image to edit. | IMAGE | Yes | - |
| `prompt` | Description of the desired edit. 1–6000 characters. Default: "" (empty string). | STRING | Yes | 1 to 6000 characters |
| `model` | Model to use for editing. | MODEL | Yes | `"uni-1"`<br>`"uni-1-max"` |
| `seed` | Seed controls whether the node should re-run; results are non-deterministic regardless of seed. Default: 0. | INT | Yes | 0 to 2147483647 |

**Parameter Constraints:**
- The `prompt` must be between 1 and 6000 characters long.
- The `model` parameter is a dynamic combo that, when set to `"uni-1"` or `"uni-1-max"`, provides additional sub-parameters (such as `style`, `web_search`, and `image_ref`). The `image_ref` sub-parameter accepts a maximum of 8 image references.

## Outputs

| Output Name | Description | Data Type |
|-------------|-------------|-----------|
| `image` | The edited image generated by the Luma UNI-1 model. | IMAGE |
