width

Integer representing the width of image to generate. None will default to 512 for SD 1.5 and 1024 for SD XL and SSD. Supported resolutions (w,h): SDXL={(1536, 640), (768, 1344), (832, 1216), (1344, 768), (1152, 896), (640, 1536), (1216, 832), (896, 1152), (1024, 1024)}, SD1.5={(768, 576), (1024, 576), (640, 512), (384, 704), (640, 768), (640, 640), (1024, 768), (1536, 1024), (768, 1024), (576, 448), (1024, 1024), (896, 896), (704, 1216), (512, 512), (448, 576), (832, 512), (512, 704), (576, 768), (1216, 704), (512, 768), (512, 832), (1024, 1536), (576, 1024), (704, 384), (768, 512)}, SSD={(1536, 640), (768, 1344), (832, 1216), (1344, 768), (1152, 896), (640, 1536), (1216, 832), (896, 1152), (1024, 1024)}

cfg_scale

number

≤ 50

Defaults to 12

Floating-point number represeting how closely to adhere to prompt description. Must be a positive number no greater than 50.0.

steps

integer

0 to 200

Defaults to 30

Integer repreenting how many steps of diffusion to run. Must be greater than 0 and less than or equal to 200.

num_images

integer

0 to 16

Defaults to 1

Integer representing how many output images to generate with a single prompt/configuration.

seed

integer | array | null

Integer number or list of integers representing the seeds of random generators. Fixing random seed is useful when attempting to generate a specific image. Must be greater than 0 and less than 2^32.

controlnet_image

Controlnet image encoded in b64 string for guiding image generation. Required for controlnet engines.

init_image

Starting point image encoded in b64 string for Image to Image generation mode.

mask_image

b64 encoded mask image for inpainting. White area should indicate where to paint.

strength

number

0 to 1

Defaults to 0.8

Floating-point number indicating how much creative the Image to Image generation mode should be. Must be greater than 0 and less than or equal to 1.0.

style_preset

SDXLStyles | null

Pre-defined styles used to guide the output image towards a particular style. Pre-defined styles are only supported by SDXL.

use_refiner

boolean

Defaults to true

Whether to enable and apply the SDXL refiner model to the image generation.

high_noise_frac

number

0 to 1

Defaults to 0.8

Floating-point number that defines the fraction of steps to perform with the base model. Used only by SD XL. Must be greater than or equal to 0.0 and less than or equal to 1.0.

number

Defaults to 1

How strong the effect of the controlnet should be.

controlnet_preprocess

boolean

Defaults to true

Whether to apply automatic ControlNet preprocessing.

clip_skip

Optionally skip later layers of the text encoder. Higher values lead to more abstract interpretations of the prompt.

string

enum

Defaults to jpeg

The image encoding types available for image generation response.
