Input Parameters

Name	Type	Description	Default	Constraints
`control_image`*	string(uri)	Image to use as control input. Must be jpeg, png, gif, or webp.	`—`	—
`prompt`*	string	Text prompt for image generation	`—`	—
`guidance`	number	Controls the balance between adherence to the text as well as image prompt and image quality/diversity. Higher values make the output more closely match the prompt but may reduce overall image quality. Lower values allow for more creative freedom but might produce results less relevant to the prompt.	`30`	min: 1, max: 100
`output_format`	string	Format of the output images.	`"jpg"`	jpgpng
`prompt_upsampling`	boolean	Automatically modify the prompt for more creative generation	`false`	—
`safety_tolerance`	integer	Safety tolerance, 1 is most strict and 6 is most permissive	`2`	min: 1, max: 6
`seed`	integer	Random seed. Set for reproducible generation	`—`	—
`steps`	integer	Number of diffusion steps. Higher values yield finer details but increase processing time.	`50`	min: 15, max: 50
