Task Submission Parameters

Request Parameters

Parameter	Type	Required	Default	Range	Description
prompt	string	Yes		-	The prompt to generate an image from.
image	string	No		-	The image to generate an image from.
strength	number	No	0.8	0.00 ~ 1.00	Strength indicates extent to transform the reference image.
num_inference_steps	integer	No	28	1 ~ 50	The number of inference steps to perform.
seed	integer	No	-1	-1 ~ 2147483647	The random seed to use for the generation. -1 means a random seed will be used.
guidance_scale	number	No	3.5	1.0 ~ 20.0	The guidance scale to use for the generation.
output_format	string	No	jpeg	jpeg, png	The format of the output image.
enable_base64_output	boolean	No	false	-	If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
enable_sync_mode	boolean	No	false	-	If set to true, the function will wait for the image to be generated and uploaded before returning the response. It allows you to get the image directly in the response. This property is only available through the API.
