Inputs (13)
| Name | Type | Default | Description |
|---|---|---|---|
| upscale_factor | FLOAT | 2.000.1–8 | Upscale multiplier. 2.0 = double the size. |
| tile_size | INT | 102464–2048 | Base tile size in pixels for tiled upscale. |
| tile_overlap | INT | 640–512 | Tile overlap in pixels. Higher = fewer seams, more VRAM. |
| auto_overlap | BOOLEAN | false | Ignore tile_overlap and derive it automatically from the tile size (~12.5%, min 32px) instead — keeps overlap proportional when you change tile_size. No effect when Full Auto is on (it already derives its own overlap). |
| auto_mode | BOOLEAN | false | Full Auto: automatically choose tile settings based on profile. |
| auto_profile | COMBO | Balanced | VRAM/quality profile for auto mode. |
| manual_tile_cols | INT | 00–64 | Force this many tile columns. 0 = compute from tile size. |
| manual_tile_rows | INT | 00–64 | Force this many tile rows. 0 = compute from tile size. |
| non_square_tiles | BOOLEAN | false | Enable non-square tiles with aspect-ratio awareness. |
| auto_fix_thin_edges | BOOLEAN | false | In Manual Tiles mode, shrink tile_size to the next standard size (1536/1024/768 → 512) instead of just warning when the grid would leave a thin edge tile. At 512 (smallest standard) it can't shrink further — the thin edge is then handled downstream by overlap/mask_blur. Does not affect an explicit manual column/row grid. |
| imageopt | IMAGE | Input image to upscale. Optional if latent is connected instead — at least one of image/latent is required. | |
| upscale_modelopt | UPSCALE_MODEL | ESRGAN-style upscale model. Only applies when image is connected — has no effect in latent-only mode. | |
| latentopt | LATENT | Optional latent to resize/tile alongside (or instead of) the image. When connected, the latent output is resized (bislerp) to the tile-aligned target and latent_tiles gets one crop per tile. Can stand in for image entirely — at least one of image/latent is required. |
Outputs (5)
| Name | Type | Description |
|---|---|---|
| image | IMAGE | Upscaled through the model, resized to the tile-aligned target. Empty placeholder when no image is connected (latent-only mode). |
| tiles | IMAGE | Batch of the actual cropped tile pieces (edge tiles shifted inward to stay full-size, no black padding). Empty placeholder when no image is connected (latent-only mode). |
| latent | LATENT | Input latent resized to the tile-aligned target (bislerp). Empty placeholder when no latent is connected. |
| latent_tiles | LATENT | Batch of latent crops, one per image tile (same grid/order as `tiles`). Empty placeholder when no latent is connected. |
| layout | FIL_TILE_LAYOUT | Tile-grid layout (exact per-tile positions) — wire into FiL Tile Assembly to recombine processed tiles. |
