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. 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" "3:4" "2:3" "3:2" "4:3" "16:9" "9:16" "21:9”
`megapixels`	Total pixel budget. 1.0 is about 1024x1024 at a square ratio. Default: 1.0.	FLOAT	No	0.1 - 16.0 (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

Output Name	Description	Data Type
`IMAGE`	The generated image returned as an image tensor, ready for further image processing or saving nodes.	IMAGE
