Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| latent | LATENT | Latent to upscale and re-noise before sampling. | |
| seed | INT | 00–18446744073709550000 | Seed controlling flow re-noise (use as Custom Sampler noise seed for determinism). |
| scale_factor | FLOAT | 1.000.1–8 | Spatial scale factor applied to the latent grid for this stage. |
| noise_ratio | FLOAT | 0.000–1 | Flow-style re-noise amount (0 = keep latent, 1 = replace with pure noise). |
| upscale_method | COMBO | bicubic | Resampling kernel for spatial upscaling. NOTE: ComfyUI's `lanczos` path uses PIL and is unsafe for LATENT tensors; this node will fall back to `bicubic` if selected. |
| reduce_memory_useopt | COMBO | enable | Enable to reduce VRAM use by avoiding extra tensor clones where possible. |
