Input Parameters
| Name | Type | Description | Default | Constraints |
|---|---|---|---|---|
prompt * | string | Text prompt for image generation | — | — |
aspect_ratio | string | Aspect ratio for the generated image. Use 'match_input_image' to match the first input image's aspect ratio. | "1:1" | match_input_image custom 1:1 16:9 3:2 2:3 4:5 5:4 9:16 3:4 4:3 |
guidance | number | Guidance scale for generation. Controls how closely the output follows the prompt | 4.5 | min: 1.5, max: 10 |
height | integer | 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). | — | min: 256, max: 2048 |
input_images | array | List of input images for image-to-image generation. Maximum 10 images. Must be jpeg, png, gif, or webp. | | — |
output_format | string | Format of the output images. | "webp" | webp jpg png |
output_quality | integer | Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs | 80 | min: 0, max: 100 |
prompt_upsampling | boolean | Automatically modify the prompt for more creative generation | true | — |
resolution | string | 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). | "1 MP" | match_input_image 0.5 MP 1 MP 2 MP 4 MP |
safety_tolerance | integer | Safety tolerance, 1 is most strict and 5 is most permissive | 2 | min: 1, max: 5 |
seed | integer | Random seed. Set for reproducible generation | — | — |
steps | integer | Number of inference steps | 30 | min: 1, max: 50 |
width | integer | 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). | — | min: 256, max: 2048 |
prompt required string Text prompt for image generation
aspect_ratio string Aspect ratio for the generated image. Use 'match_input_image' to match the first input image's aspect ratio.
"1:1" guidance number Guidance scale for generation. Controls how closely the output follows the prompt
4.5 min: 1.5, max: 10 height integer 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).
input_images array List of input images for image-to-image generation. Maximum 10 images. Must be jpeg, png, gif, or webp.
output_format string Format of the output images.
"webp" output_quality integer Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs
80 min: 0, max: 100 prompt_upsampling boolean Automatically modify the prompt for more creative generation
true resolution string 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).
"1 MP" safety_tolerance integer Safety tolerance, 1 is most strict and 5 is most permissive
2 min: 1, max: 5 seed integer Random seed. Set for reproducible generation
steps integer Number of inference steps
30 min: 1, max: 50 width integer 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).
