# Grok Image Node

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 |
