# GrokImageNode - ComfyUI Built-in Node Documentation

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

The Grok Image node generates one or more images based on a text description using the Grok AI model. It sends your prompt to an external service and returns the generated images as tensors that can be used in your workflow.

## Inputs

| Parameter          | Description                                                                                                                      | Data Type | Required | Range                                                                                                                                                                         |
| ------------------ | -------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model`            | The specific Grok model to use for image generation. Different models may offer varying quality, speed, or features.             | COMBO     | Yes      | `"grok-imagine-image-quality"`<br />`"grok-imagine-image-pro"`<br />`"grok-imagine-image"`                                                                                    |
| `prompt`           | The text prompt used to generate the image. This description guides the AI on what to create. Must be at least 1 character long. | STRING    | Yes      | N/A                                                                                                                                                                           |
| `aspect_ratio`     | The desired width-to-height ratio for the generated image.                                                                       | COMBO     | Yes      | `"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"` |
| `number_of_images` | Number of 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                                                                                                                                                               |
| `resolution`       | The desired output resolution for the generated images (default: "1K").                                                          | COMBO     | No       | `"1K"`<br />`"2K"`                                                                                                                                                            |

**Note:** The `seed` parameter is primarily used to control when the node re-executes within a workflow. Due to the nature of the external AI service, the generated images will not be reproducible or identical across runs, even with an identical seed.

**Note on pricing:** The cost of generating images depends on the selected `model`, `resolution`, and `number_of_images`. For example, the "grok-imagine-image-quality" model with "1K" resolution costs $0.05 per image, while "2K" resolution costs $0.07 per image. The "grok-imagine-image-pro" model costs $0.07 per image, and other models cost $0.02 per image.

## Outputs

| Output Name | Description                                                                                                                                                       | Data Type |
| ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `output`    | The generated image or a batch of images. If `number_of_images` is 1, a single image tensor is returned. If greater than 1, a batch of image tensors is returned. | IMAGE     |
