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	Data Type	Required	Range	Description
`prompt`	STRING	Yes	-	Prompt for the image generation (default: empty string)
`prompt_upsampling`	BOOLEAN	Yes	-	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)
`width`	INT	Yes	256-1440	Image width in pixels (default: 1024, step: 32)
`height`	INT	Yes	256-1440	Image height in pixels (default: 768, step: 32)
`seed`	INT	Yes	0-18446744073709551615	The random seed used for creating the noise. (default: 0)
`image_prompt`	IMAGE	No	-	Optional reference image to guide the generation
