About Z Image Turbo Inpaint

Edits part of an image: provide `image_url`, a `mask_image_url` marking the area to change, and a `prompt` describing what to generate. `strength` and the control settings (`control_scale`, `control_start`, `control_end`) adjust how closely the result follows the original. It runs up to 8 inference steps, returns 1 to 4 images, and can output png, jpeg or webp.

Parameters

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