# 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 | Data Type | Required | Range | Description |
| ------------------ | --------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `model` | COMBO | Yes | `"grok-imagine-image-beta"` | The specific Grok model to use for image generation. |
| `prompt` | STRING | Yes | N/A | The text prompt used to generate the image. This description guides the AI on what to create. |
| `aspect_ratio` | COMBO | Yes | `"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 desired width-to-height ratio for the generated image. |
| `number_of_images` | INT | No | 1 to 10 | Number of images to generate (default: 1). |
| `seed` | INT | No | 0 to 2147483647 | A seed value to determine if the node should re-run. The actual image results are nondeterministic and will vary even with the same seed (default: 0). |
**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.
## Outputs
| Output Name | Data Type | Description |
| ----------- | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `output` | IMAGE | 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. |
