## Overview

Modify an existing image based on a text prompt. This node sends your images and a text description to the Grok API, which edits the images according to your instructions and returns the result.

## Inputs

| Parameter | Data Type | Required | Range           | Description                                                                                                                                                                                                                                                               |
| --------- | --------- | -------- | --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `prompt`  | STRING    | Yes      | N/A             | The text prompt used to generate the image. Must be at least 1 character long after stripping whitespace.                                                                                                                                                                 |
| `model`   | MODEL     | Yes      | See Description | The Grok image model to use. This parameter has multiple sub-options that appear after selecting a model. Available models: `grok-imagine-image-quality`<br />`grok-imagine-image-pro`<br />`grok-imagine-image`. Each model has different capabilities (see note below). |
| `seed`    | INT       | Yes      | 0 to 2147483647 | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed. (default: 0)                                                                                                                                                             |

**Note on `model` parameter constraints:**

* The `model` parameter is a dynamic combo that includes sub-options for `resolution`, `number_of_images`, `images`, and `aspect_ratio`.
* **`grok-imagine-image-quality`**: Supports up to 3 input images and allows custom aspect ratio.
* **`grok-imagine-image-pro`**: Supports only 1 input image and does not allow custom aspect ratio.
* **`grok-imagine-image`**: Supports up to 3 input images and allows custom aspect ratio.
* **At least one input image is required** for editing. The node will raise an error if no images are provided.
* **Custom aspect ratio** (`aspect_ratio` sub-option) is only allowed when multiple images are connected to the image input. If only one image is provided, aspect ratio must be set to "auto".

## Outputs

| Output Name | Data Type | Description                                                                                                                                                                                |
| ----------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `IMAGE`     | IMAGE     | The edited image(s) returned by the Grok API. If a single image is generated, it is returned directly. If multiple images are generated, they are concatenated into a single batch tensor. |
