SAX Upscaler
Upscales images in the pipe. Using an ESRGAN model enables high-quality enlargement and allows lower denoise in downstream Detailer nodes.

Inputs (7)
| Name | Type | Default | Description |
|---|---|---|---|
| pipe | PIPE_LINE | — | |
| upscale_model_name | COMBO | Upscale model to use. None = pixel interpolation only. | |
| method | COMBO | Pixel interpolation method. When upscale_model_name is set, model-based upscaling takes priority; this method is used only for final resize adjustment. | |
| scale_by | FLOAT | 2.000.25–8 | Scale factor relative to original resolution. For a 4x ESRGAN model, scale_by=2 upscales 4x then downscales to 1/2. |
| denoise | FLOAT | 0.000–1 | 0=upscale only / Values > 0 run a lightweight img2img pass after upscaling. |
| steps_override | INT | 00–200 | Steps for img2img pass. 0 = inherit from loader_settings. |
| cfg_override | FLOAT | 0.00–100 | CFG for img2img pass. 0.0 = inherit from loader_settings. Values > 0 override it. |
