ComfyCloudFlux2TextToImageNode - ComfyUI Built-in Node Documentation - ComfyUI

Runs the Flux 2 dev text-to-image model on a Comfy Cloud GPU and returns the generated image. The turbo option applies the Turbo LoRA with a short schedule for a much quicker run at the cost of a little fidelity; turning it off performs the full-length dev pass without the LoRA. This is a beta node set, billed by how long it runs in credits.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	The text prompt describing the image to generate. Leading and trailing whitespace is removed before submission.	STRING	Yes	1 to 4096 characters
`seed`	Random seed that controls the generated result for reproducibility (default: 42).	INT	Yes	0 to 18446744073709551615
`aspect_ratio`	Aspect ratio of the output image (default: “1:1”).	COMBO	Yes	”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	Yes	0.1 to 16.0 (step 0.1)
`turbo`	Run the Turbo LoRA on a short schedule, trading a little fidelity for a much quicker run. Off runs the full dev pass with no LoRA (default: True).	BOOLEAN	Yes	True / False

Outputs

Output Name	Description	Data Type
`IMAGE`	The image generated from the text prompt, returned as a ComfyUI image tensor that can be passed to other nodes.	IMAGE
