Inputs (12)

Name	Type	Default	Description
image_urls	IMAGE		—
prompt	STRING	Replace the backpack in the first image with the colour scheme from the second image, and leave everything else unchanged	The prompt describing the result you want. Required. Any language is supported, up to 5000 characters; longer input returns 422. When `mask_url` is supplied, use it to describe what should be generated inside the white area of the mask.
aspect_ratioopt	COMBO	auto	Output aspect ratio. Defaults to `auto`, which takes the aspect ratio of the first reference image and snaps it to the nearest supported ratio. The actual pixel size also depends on `resolution` — see the aspect ratio table above. Ignored in local-edit mode.
resolutionopt	COMBO	1K	Output resolution tier. `1K` is the faster option; `2K` produces four times the pixels and takes considerably longer, up to about 3 minutes with reference images. Only `1K` and `2K` are accepted — any other value, including `4K`, returns 422.
backgroundopt	COMBO	opaque	Background type. transparent outputs a PNG or WebP with a real alpha channel and cannot be used with JPEG. When using transparent, describe only the subject — prompts that mention a background, scene, surface, etc. may produce a non-transparent result.
output_formatopt	COMBO	png	Output image format. `png` (default) and `webp` both carry an alpha channel and can be used with `background: transparent`. `jpeg` has no alpha channel and cannot be combined with a transparent background.
enhance_promptopt	BOOLEAN	true	Rewrites the prompt into a fuller scene description before generating, which noticeably improves quality. Enabled by default (also when the parameter is omitted); pass false to turn it off.
seedopt	INT	20260921-2147483648–2147483647	The random seed. Omit it to generate with a random seed; the seed actually used is returned with the result. Passing the same seed together with the same prompt and parameters reproduces the same image within the same service version.
mask_urlopt	STRING	https://example.com/room-mask.png	Inpainting mask that switches the request into local-edit mode. A black and white image where white marks the area to change and black is kept unchanged, with a few pixels of feathering along the boundary. It must be used with exactly one entry in `image_urls`, otherwise the request returns 422. The mask should have the same aspect ratio as that reference image; a mask of a different size is scaled to it. In local-edit mode the output ratio follows the reference image, so `aspect_ratio` and `enhance_prompt` are ignored and reported in the `ignored` field of the result. It cannot be combined with `background: transparent`, which returns 422.
nsfw_checkeropt	BOOLEAN	false	Defaults to false. You can set it to false based on your needs. If set to false, our content filtering will be disabled, and all results will be returned directly by the model itself. Note: There is no guarantee that everything can be filtered out; if you are not satisfied with the results, you will need to make your own arrangements.
timeout_secondsopt	INT	120030–7200	—
callback_urlopt	STRING		Optional KIE callback URL. Leave empty for normal ComfyUI use.
