Inputs (14)

Name	Type	Default	Description
image	IMAGE		—
upscale_method	COMBO	AI upscaler model (ESRGAN, etc.)	AI models can add detail but may round small objects. Standard resize methods preserve source geometry and need no model.
min_tile_size	INT	1024256–4096	Minimum processing tile size in final sampler pixels.
max_tile_size	INT	1536256–4096	Maximum processing tile size in final sampler pixels.
overlap	INT	320–1024	Total shared overlap in final sampler pixels.
feather	INT	160–512	Blend fade width in final sampler pixels.
scale_factor	FLOAT	2.001–12	How many times larger the final image is. High scales multiply tile count and time: a 1340x896 source at 12x renders about 90 tiles.
divisible_by	INT	161–256	—
upscale_batch_size	INT	11–16	Tiles sent through an AI upscaler together. Ignored by standard resize methods.
padding_mode	COMBO	edge	How tiles that reach past the image border are filled before enlargement. Edge repeats the outermost pixels (right for photos - leave it here). Zero fills black, only useful for images with true black borders.
cache_mode	COMBO	read_write	Reuse enlarged tiles from disk, regenerate them, or skip the disk cache.
cache_tag	STRING	auto	Optional cache label. The upscaler weights are fingerprinted automatically.
preview_max_size	INT	1600512–8192	Maximum dimension of the output-scale diagnostic preview.
upscale_modelopt	UPSCALE_MODEL		Required only when the AI upscaler method is selected.
