}

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). Note: Ignored in img2img and inpainting modes.
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). Note: Ignored in img2img and inpainting modes.
prompt (required) Type: string: Text prompt for image generation
aspect_ratio Default: 1:1: Aspect ratio for the generated image
image_prompt Type: string: Image to use with Flux Redux. This is used together with the text prompt to guide the generation towards the composition of the image_prompt. 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
safety_tolerance Type: integerDefault: 2Range: 1 - 6: Safety tolerance, 1 is most strict and 6 is most permissive
prompt_upsampling Type: booleanDefault: false: Automatically modify the prompt for more creative generation
