# GrokImageNode - ComfyUI Built-in Node Documentation

> The Grok Image node generates one or more images from a text description using the Grok AI model.

The Grok Image node generates one or more images from 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-2.0"`<br />`"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 (whitespace-only text is not accepted). | 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 | Yes | 1 to 10 |
| `seed` | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0). | INT | Yes | 0 to 2147483647 |
| `resolution` | The desired output resolution for the generated images (default: "1K"). | COMBO | No | `"1K"`<br />`"2K"` |
| `quality` | Quality level, supported only by the `grok-imagine-image-2.0` model (default: "medium"; "low" is one of the available options). For all other models, this setting is ignored. | COMBO | No | Multiple options available |

**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`, `quality`, and `number_of_images`. For the `grok-imagine-image-2.0` model, "low" quality costs $0.04 per image at 1K resolution and $0.06 per image at 2K resolution; other quality levels cost $0.06 per image at 1K and $0.08 per image at 2K. The `grok-imagine-image-quality` model costs $0.05 per image at 1K resolution and $0.07 per image at 2K resolution. The `grok-imagine-image-pro` model costs $0.07 per image. The `grok-imagine-image` model costs $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 |
