# ComfyCloudZImageTurboNode - ComfyUI Built-in Node Documentation

> This node generates an image from a text prompt using the Z-Image Turbo model, which completes in just 8 steps.

This node generates an image from a text prompt using the Z-Image Turbo model, which completes in just 8 steps. The generation runs remotely on Comfy Cloud GPUs and is billed by GPU time, making this one of the quickest and cheapest options here for iterating on image ideas. Once the generation finishes, the node downloads the finished image for use in your workflow.

## Inputs

| Parameter      | Description                                                                                                                                                | Data Type | Required | Range                                                                                 |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------------------------------------------------------- |
| `prompt`       | Text prompt describing the image to generate. Accepts multi-line input and is trimmed before submission. Must not be empty after trimming.                 | STRING    | Yes      | 1 - 4096 characters                                                                   |
| `seed`         | Random seed used to control generation reproducibility. Changing it produces a different variation. Includes a control-after-generate option. Default: 42. | INT       | No       | 0 - 18446744073709551615                                                              |
| `aspect_ratio` | Aspect ratio of the generated image. Default: "1:1".                                                                                                       | COMBO     | No       | "1:1"<br />"3:4"<br />"2:3"<br />"3:2"<br />"4:3"<br />"16:9"<br />"9:16"<br />"21:9" |
| `megapixels`   | Total pixel budget. 1.0 is about 1024x1024 at a square ratio. Default: 1.0.                                                                                | FLOAT     | No       | 0.1 - 16.0<br />(step of 0.1)                                                         |

Note: Input values are validated before the generation is submitted. The `prompt` must contain between 1 and 4,096 characters after whitespace is trimmed, `aspect_ratio` must be one of the listed options, and `megapixels` must be entered in increments of 0.1.

## Outputs
