Input

Field	Kind	Default	Description
`prompt` required	text	—	Text prompt for image generation
`seed`	number (whole)	—	Random seed. Set for reproducible generation
`width`	number (whole) 256 to 2048	—	Width of the generated image. Only used when aspect_ratio=custom. Must be a multiple of 16 (if it's not, it will be rounded to nearest multiple of 16).
`height`	number (whole) 256 to 2048	—	Height of the generated image. Only used when aspect_ratio=custom. Must be a multiple of 16 (if it's not, it will be rounded to nearest multiple of 16).
`resolution`	JSON	1 MP	Resolution in megapixels. Up to 4 MP is possible, but 2 MP or below is recommended. The maximum image size is 2048x2048, which means that high-resolution images may not respect the resolution if aspect ratio is not 1:1. Resolution is not used when aspect_ratio is 'custom'. When aspect_ratio is 'match_input_image', use 'match_input_image' to match the input image's resolution (clamped to 0.5-4 MP).
`aspect_ratio`	JSON	1:1	Aspect ratio for the generated image. Use 'match_input_image' to match the first input image's aspect ratio.
`input_images`	list	[]	List of input images for image-to-image generation. Maximum 8 images. Must be jpeg, png, gif, or webp.
`output_format`	JSON	webp	Format of the output images.
`output_quality`	number (whole) 0 to 100	80	Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs
`safety_tolerance`	number (whole) 1 to 5	2	Safety tolerance, 1 is most strict and 5 is most permissive
