# GrokImageEditNode - ComfyUI Built-in Node Documentation
> Complete documentation for the GrokImageEditNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.
> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/GrokImageEditNode/en.md)
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 | Data Type | Required | Range | Description |
| ------------------ | --------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model` | COMBO | Yes | `"grok-imagine-image-quality"`
`"grok-imagine-image-pro"`
`"grok-imagine-image"`
`"grok-imagine-image-beta"` | The specific AI model to use for image editing. |
| `image` | IMAGE | Yes | | The input image(s) to be edited. Supports up to 3 input images, except for the "pro" model which supports only 1. |
| `prompt` | STRING | Yes | | The text prompt used to generate the edited image. Must be at least 1 character after stripping whitespace. |
| `resolution` | COMBO | Yes | `"1K"`
`"2K"` | The resolution for the output image. |
| `number_of_images` | INT | No | 1 to 10 | Number of edited images to generate (default: 1). |
| `seed` | INT | No | 0 to 2147483647 | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0). |
| `aspect_ratio` | COMBO | No | `"auto"`
`"1:1"`
`"2:3"`
`"3:2"`
`"3:4"`
`"4:3"`
`"9:16"`
`"16:9"`
`"9:19.5"`
`"19.5:9"`
`"9:20"`
`"20:9"`
`"1:2"`
`"2:1"` | 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"). |
**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 | Data Type | Description |
| ----------- | --------- | ------------------------------------------------------------------------------------------------------------------------------ |
| `output` | IMAGE | The edited image(s) generated by the node. If `number_of_images` is greater than 1, the outputs are concatenated into a batch. |
