Inputs (22)
| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | — | |
| model | MODEL | — | |
| seed | INT | 00–18446744073709550000 | — |
| upscale_by | FLOAT | 2.000.1–10000 | Final resolution multiplier (e.g., 2.0 = double width and height). |
| upscale_curve | FLOAT | 1.000–10 | Progression curve for all parameters. 1.0 = linear. >1.0: resolution accelerates, CFG/steps/denoise front-loaded. <1.0: resolution front-loaded, CFG/steps/denoise accelerate. |
| iterations | INT | 40–20 | Number of complete sampling cycles to perform. |
| steps_start | INT | 171–10000 | Number of sampling steps for the first iteration. |
| steps_end | INT | 71–10000 | Number of sampling steps for the last iteration. |
| cfg_start | FLOAT | 7.00–10000 | CFG scale for the first iteration. |
| cfg_end | FLOAT | 1.00–10000 | CFG scale for the last iteration. |
| denoise_start | FLOAT | 1.000–1 | Denoise strength for the first iteration. |
| denoise_end | FLOAT | 0.150–1 | Denoise strength for the last iteration. |
| add_noise | FLOAT | 0.00–100 | Adds noise before denoising each iteration. The amount added is relative to the current denoise. |
| fix_vae_color | BOOLEAN | true | Apply color correction after each iteration to maintain color consistency with the original image. |
| sampler_name | COMBO | res_2m | 44 options: euler, euler_cfg_pp, euler_ancestral, euler_ancestral_cfg_pp, heun, heunpp2, +38 |
| scheduler | COMBO | bong_tangent | 9 options: simple, sgm_uniform, karras, exponential, ddim_uniform, beta, +3 |
| positive | CONDITIONING | — | |
| negative | CONDITIONING | — | |
| resize_filter | COMBO | lanczos | Image resizing filter algorithm. |
| decode_size | INT | 1024320–2048 | Decode size for VAE operations. |
| vae | VAE | — | |
| upscale_modelopt | UPSCALE_MODEL | Optional AI upscaling model (e.g., ESRGAN, Real-ESRGAN) for enhanced image quality during upscaling. |
