List of URLs of input images for editing. Presently, up to 10 image inputs are allowed.

image_size

The size of the generated image.

image_resolution

Final image resolution is determined by combining image_size (aspect ratio) and image_resolution (pixel scale). For example, choosing 4:3 + 4K gives 4096 × 3072px

max_images

Set this value (1–6) to cap how many images a single generation run can produce in one set—because they’re created in one shot rather than separate requests, you must also state the exact number you want in the prompt so both settings align.

seed

Random seed to control the stochasticity of image generation.

nsfw_checker

A configurable parameter. Defaults to true in the Playground.
