Parameters

10 fields in input, required first.

• promptRequired
  string

  Prompt for generated image

• aspect_ratioOptional
  1:1, 16:9, 21:9, 3:2, 2:3, 4:5, 5:4, 3:4, 4:3, 9:16, 9:21Default 1:1

  Aspect ratio for the generated image

• num_outputsOptional
  integerDefault 1

  Number of outputs to generate

• num_inference_stepsOptional
  integerDefault 4

  Number of denoising steps. 4 is recommended, and lower number of steps produce lower quality outputs, faster.

• seedOptional
  integer

  Random seed. Set for reproducible generation

• output_formatOptional
  webp, jpg, pngDefault webp

  Format of the output images

• output_qualityOptional
  integerDefault 80

  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_checkerOptional
  booleanDefault false

  Disable safety checker for generated images.

• go_fastOptional
  booleanDefault true

  Run faster predictions with model optimized for speed (currently fp8 quantized); disable to run in original bf16. Note that outputs will not be deterministic when this is enabled, even if you set a seed.

• megapixelsOptional
  1, 0.25Default 1

  Approximate number of megapixels for generated image
