Field	Type	Description
seed	—	The same seed and the same prompt given to the same version of the model will output the same image every time.
promptrequired	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.
image_size	—	The size of the generated image.
num_images	integer	The number of images to generate.
acceleration	stringenum: none, regular, high	The speed of the generation. The higher the speed, the faster the generation.
output_format	stringenum: jpeg, png	The format of the generated image.
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.
