Parameters

Name Required Description Default / Options
aspect_ratio optional Aspect ratio for the generated image. Use 'match_input_image' to match the first input image's aspect ratio. match_input_imagecustom1:116:93:22:34:55:49:163:44:3
height optional Height of the generated image. 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). —
output_format optional Format of the output images. webpjpgpng
output_quality optional Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs 80
prompt required Text prompt for image generation —
resolution optional 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). match_input_image0.5 MP1 MP2 MP4 MP
safety_tolerance optional Safety tolerance, 1 is most strict and 5 is most permissive 5
seed optional Random seed. Set for reproducible generation —
width optional Width of the generated image. 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). —
