high_noise_fracdoubleOptionalDefaults to 0.8
[Not supported on SD3, FLUX] 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.
image_encoding"jpeg" or "png"Optional
Allowed values: jpegpng
Define which encoding process should be applied before returning the generated image(s).
init_imagestringOptional
Starting point image encoded in b64 string for Image to Image generation mode.
inpaint_full_resbooleanOptional

When true, upsample ‘init_image’ and ‘mask_image’ such that a bounding box drawn around the non-black content of ‘mask_image’ becomes the full inpainting frame. The bounding box has the same aspect ratio as that specified by (‘height’, ‘width’) parameters.

inpaint_full_res_paddingintegerOptionalDefaults to 32

When ‘inpaint_full_res’ is true, include a frame around the non-black mask area that is this many pixels wide. This serves as a form of context for the inpainting and may improve blending.

log_promptbooleanOptional
OctoAI stores request prompt if True.
lorasmap from strings to optional doublesOptional
[Not supported on SD3] A dictionary of LoRAs to apply. LoRAs as keys and their weights (float) as values.
mask_imagestringOptional
[Not supported on SD3] b64 encoded mask image for inpainting. White area should indicate where to paint.
negative_promptstringOptional
[Not supported on FLUX] Text describing image traits to avoid during generation.
negative_prompt_2stringOptional
[Not supported on SD3, FLUX] Text with a high level description of things to avoid during generation. Used only by SD XL.
num_imagesintegerOptionalDefaults to 1
Integer representing how many output images to generate with a single prompt/configuration.
outpaintingbooleanOptional
[Not supported on SD3, FLUX] Whether the request requires outpainting or not. If so, special preprocessing is applied for better results.

samplerenumOptional
[Not supported on SD3, FLUX] Sampler name (also known as 'scheduler') to use during image generation.
