Input Parameters

seed Type: integer: Random seed. Set for reproducible generation.
width Type: integerRange: 256 - 1440: Width of the generated image in text-to-image mode. Only used when aspect_ratio=custom. Must be a multiple of 32 (if it's not, it will be rounded to nearest multiple of 32).
height Type: integerRange: 256 - 1440: Height of the generated image in text-to-image mode. Only used when aspect_ratio=custom. Must be a multiple of 32 (if it's not, it will be rounded to nearest multiple of 32).
prompt (required) Type: string: Text description of the image to generate.
go_fast Type: booleanDefault: true: Run faster predictions with additional optimizations.
aspect_ratio Default: 1:1: Aspect ratio for the generated image. Use 'match_input_image' to match the first input image's aspect ratio.
input_images Type: arrayDefault:: List of input images for image-to-image generation. Maximum 4 images. Must be jpeg, png, gif, or webp.
output_format Default: webp: Format of the output images.
output_quality Type: integerDefault: 80Range: 0 - 100: Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs.
disable_safety_checker Type: booleanDefault: false: Disable safety checker for generated images.
