# QwenImageEditApi - ComfyUI Built-in Node Documentation

> This node uses the Qwen-Image 3.0 models to edit or combine up to 3 reference images guided by a text prompt.

This node uses the Qwen-Image 3.0 models to edit or combine up to 3 reference images guided by a text prompt. You provide the text prompt and the reference images, and the node returns the generated result as one or more images.

## Inputs

| Parameter       | Description                                                                                                                                                                         | Data Type | Required | Range                                      |
| --------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------------ |
| `model`         | Model to use. This selection also includes the text prompt, up to 3 reference image inputs, and an optional negative prompt.                                                        | COMBO     | Yes      | "qwen-image-3.0-pro"<br />"qwen-image-3.0" |
| `size`          | Output resolution. "match input" reuses the first reference image's size, "auto" lets the model pick a size with the same aspect ratio, "custom" sets an explicit width and height. | COMBO     | Yes      | "match input"<br />"auto"<br />"custom"    |
| `n`             | Number of images to generate, returned as a batch. (default: 1)                                                                                                                     | INT       | No       | 1 to 6                                     |
| `seed`          | Seed to use for generation. (default: 42)                                                                                                                                           | INT       | No       | 0 to 2147483647                            |
| `prompt_extend` | Whether to enhance the prompt with AI assistance. (default: True)                                                                                                                   | BOOLEAN   | No       | True<br />False                            |
| `watermark`     | Whether to add an AI-generated watermark to the result. (default: False)                                                                                                            | BOOLEAN   | No       | True<br />False                            |

### Constraints

* The text prompt is required and must contain at least one character.
* A maximum of 3 reference images is supported; an error is raised if more are provided (a batched input counts once per image).
* When `size` is set to "custom", explicit width and height values must be provided and are validated.
* When `size` is set to "match input", at least one reference image is required because the first reference image's dimensions are used.

## Outputs
