Inputs (21)

Name	Type	Default	Description
upscaled_image	IMAGE		The image to upscale.
guider	GUIDER		A guider that encapsulates the model, conditioning, and CFG. Use CFGGuider, PerpNegGuider, or other guider nodes.
sampler	SAMPLER		The sampler to use. Use KSamplerSelect node to create this.
sigmas	SIGMAS		The noise schedule. Use BasicScheduler or other scheduler nodes to create this. The denoise is configured in the scheduler.
vae	VAE		The VAE model to use for tiles.
seed	INT	00–18446744073709550000	The seed to use for noise generation.
mode_type	COMBO		The tiling order to use for the redraw step.
tile_width	INT	51264–8192	The width of each tile.
tile_height	INT	51264–8192	The height of each tile.
mask_blur	INT	80–64	The blur radius for the mask.
tile_padding	INT	320–8192	The padding to apply between tiles.
seam_fix_mode	COMBO		The seam fix mode to use.
seam_fix_denoise	FLOAT	1.000–1	The denoising strength to use for the seam fix.
seam_fix_width	INT	640–8192	The width of the bands used for the Band Pass seam fix mode.
seam_fix_mask_blur	INT	80–64	The blur radius for the seam fix mask.
seam_fix_padding	INT	160–8192	The padding to apply for the seam fix tiles.
tile_overlap_mode	COMBO	Reprocess Overlap	How to handle tile overlap regions. 'Ignore Overlap' uses minimal tile sizes. 'Reprocess Overlap' uses uniform tiles with overlap regions potentially regenerated. 'Context Only Overlap' uses uniform tiles where overlap regions from previous tiles become read-only context.
tiled_decode	BOOLEAN	false	Whether to use tiled decoding when decoding tiles.
batch_size	INT	11–4096	The number of tiles to process in a batch. Higher values can reduce processing time but use more VRAM. Yields different results than individual tiles. Only affects the main redraw step, not the seam fix step.
maskopt	MASK		Optional region mask. Only masked (white) areas are re-diffused; tiles that do not touch the mask are skipped entirely, which greatly speeds up small-region upscales. Sampling still sees the full tile for context, and blending uses the same mask_blur feathering as tile edges (the edit extends about mask_blur pixels past the mask). The mask may be any resolution and is resized to the upscaled canvas. Grayscale values give partial blending. With batched images, a single mask applies to every image, and a batch of masks maps one mask to each image. Not compatible with batch_size > 1 (tile batching).
anchor_contextopt	BOOLEAN	false	Hold the areas a tile will not composite back to the original image at every sampling step, so the model sees the true surroundings instead of a re-diffused version that can drift. Keeps detail consistent between sections and blends seams into the real image. Takes effect when a mask is connected or tile_overlap_mode is 'Context Only Overlap'; otherwise it has no effect.
