default

Unwanted image content to exclude, including elements, styles, and artifacts.

output_format default png

Format of the output image: PNG retains transparency, while JPEG produces smaller files.

default 28

Denoising iteration count, trading longer generation time for potentially better quality as the count rises.

default 4

Prompt adherence control: increase this value to make the result follow the prompt more closely.

Seed controlling generation randomness. Reusing a seed produces consistent, reproducible results.

About Uso

Takes `input_image_urls` in the order content image, style image and optional extra style image. The prompt can be empty for pure style transfer, and `negative_prompt` excludes unwanted elements. `keep_size` preserves the content image's layout and dimensions. It produces 1 to 4 images per run, with 1 to 50 steps and PNG or JPEG output.

Parameters

Send either the canonical name or the native name, not both. Canonical names
