Inputs (14)
| Name | Type | Default | Description |
|---|---|---|---|
| model_high | MODEL | The HIGH noise model (handles initial denoising steps). | |
| model_low | MODEL | The LOW noise model (handles final denoising steps). | |
| seed | INT | 00–18446744073709550000 | The random seed used for creating the noise. |
| steps | INT | 81–10000 | Total number of denoising steps. |
| switch_step | INT | 41–10000 | Step at which to switch from HIGH to LOW model. |
| first_cfg | FLOAT | 6.00–100 | CFG scale for HIGH model phase. |
| second_cfg | FLOAT | 6.00–100 | CFG scale for LOW model phase. |
| sampler_name | COMBO | The sampling algorithm to use. | |
| scheduler | COMBO | The scheduler for noise removal. | |
| positive | CONDITIONING | Positive conditioning (prompt). | |
| negative | CONDITIONING | Negative conditioning. | |
| latent_image | LATENT | The latent image to denoise. | |
| denoise | FLOAT | 1.000–1 | Denoising strength. |
| offload_between_phases | BOOLEAN | false | Unload models from VRAM between the HIGH and LOW phases and again after sampling. Helps on low-VRAM GPUs at the cost of reload time. |
