FluxProImageNode - ComfyUI Built-in Node Documentation

Generates images synchronously based on prompt and resolution. This node creates images using the Flux 1.1 Pro model by sending requests to an API endpoint and waiting for the complete response before returning the generated image.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Prompt for the image generation (default: empty string)	STRING	Yes	-
`prompt_upsampling`	Whether to perform upsampling on the prompt. If active, automatically modifies the prompt for more creative generation, but results are nondeterministic (same seed will not produce exactly the same result). (default: False)	BOOLEAN	Yes	-
`width`	Image width in pixels (default: 1024, step: 32)	INT	Yes	256-1440
`height`	Image height in pixels (default: 768, step: 32)	INT	Yes	256-1440
`seed`	The random seed used for creating the noise. (default: 0)	INT	Yes	0-18446744073709551615
`image_prompt`	Optional reference image to guide the generation	IMAGE	No	-
