Request body

10 properties · 2 required · 0 $defs

property	type	description	constraints
prompt*	string	The prompt to generate an image from.
image_url*	string	The URL of the image 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
enable_safety_checker	boolean	If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images.	default: true
output_format	enum	The format of the generated image.	jpeg \| png · default: "png"
strength	number	The strength of the initial image. Higher strength values are better for this model.	0.01 ≤ n ≤ 1 · default: 0.95
seed	integer	The same seed and the same prompt given to the same version of the model will output the same image every time.	nullable
num_inference_steps	integer	The number of inference steps to perform.	10 ≤ n ≤ 50 · default: 40
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 ≤ 20 · default: 3.5
num_images	integer	The number of images to generate.	1 ≤ n ≤ 4 · default: 1
