Request body

13 properties · 2 required · 1 $defs

property	type	description	constraints
image_url*	string	URL of image to use for image to image
prompt*	string	The prompt to generate an image from.
sync_mode	boolean	If `True`, the media will be returned as a data URI and the output data won't be available in the request history.	default: false
negative_prompt	string	The negative prompt to use. Use it to address details that you don't want in the image. This could be colors, objects, scenery and even the small details (e.g. moustache, blurry, low resolution).	default: ""
guidance_scale	number	The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you.	1 ≤ n ≤ 10 · default: 5
num_inference_steps	integer	The number of inference steps to perform.	1 ≤ n ≤ 150 · default: 50
scheduler	enum	The scheduler to use for the model.	EulerDiscreteScheduler \| EulerAncestralDiscreteScheduler… \| DPMSolverMultistepScheduler \| DPMSolverMultistepScheduler_SDE… \| UniPCMultistepScheduler \| DEISMultistepScheduler · default: "EulerDiscreteScheduler"
num_images	integer	The number of images to generate.	1 ≤ n ≤ 8 · default: 1
image_size	ImageSize \| enum	The size of the generated image.
seed	integer	Seed	nullable
strength	number	The strength to use for image-to-image. 1.0 is completely remakes the image while 0.0 preserves the original.	0.01 ≤ n ≤ 1 · default: 0.85
output_format	enum	The format of the generated image.	jpeg \| png · default: "png"
enable_safety_checker	boolean	Enable safety checker. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images.	default: true
