# GrokImageEditNode - ComfyUI Built-in Node Documentation

> Complete documentation for the GrokImageEditNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The Grok Image Edit node modifies an existing image based on a text prompt. It uses the Grok API to generate one or more new images that are variations of the input, guided by your description.

## Inputs

| Parameter          | Description                                                                                                                                                                                  | Data Type | Required | Range                                                                                                                                                                                       |
| ------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model`            | The specific AI model to use for image editing.                                                                                                                                              | COMBO     | Yes      | `"grok-imagine-image-quality"`<br />`"grok-imagine-image-pro"`<br />`"grok-imagine-image"`                                                                                                  |
| `image`            | The input image(s) to be edited. Supports up to 3 input images, except for the "pro" model which supports only 1.                                                                            | IMAGE     | Yes      |                                                                                                                                                                                             |
| `prompt`           | The text prompt used to generate the edited image. Must be at least 1 character after stripping whitespace.                                                                                  | STRING    | Yes      |                                                                                                                                                                                             |
| `resolution`       | The resolution for the output image.                                                                                                                                                         | COMBO     | Yes      | `"1K"`<br />`"2K"`                                                                                                                                                                          |
| `number_of_images` | Number of edited images to generate (default: 1).                                                                                                                                            | INT       | No       | 1 to 10                                                                                                                                                                                     |
| `seed`             | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0).                                                                                | INT       | No       | 0 to 2147483647                                                                                                                                                                             |
| `aspect_ratio`     | The aspect ratio for the output image. Only allowed when multiple images are connected to the image input. If set to "auto", the aspect ratio is determined automatically (default: "auto"). | COMBO     | No       | `"auto"`<br />`"1:1"`<br />`"2:3"`<br />`"3:2"`<br />`"3:4"`<br />`"4:3"`<br />`"9:16"`<br />`"16:9"`<br />`"9:19.5"`<br />`"19.5:9"`<br />`"9:20"`<br />`"20:9"`<br />`"1:2"`<br />`"2:1"` |

**Important constraints:**

* The `image` input supports up to 3 images, except when using the `grok-imagine-image-pro` model, which supports only 1 input image.
* The `aspect_ratio` parameter can only be set to a custom value (not "auto") when multiple images are connected to the `image` input. Setting a custom aspect ratio with a single input image will cause an error.

## Outputs

| Output Name | Description                                                                                                                    | Data Type |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------ | --------- |
| `output`    | The edited image(s) generated by the node. If `number_of_images` is greater than 1, the outputs are concatenated into a batch. | IMAGE     |
