Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | The model to calibrate (e.g. Krea 2 Turbo NVFP4) | |
| positive | CONDITIONING | — | |
| latent_image | LATENT | At the resolution you really generate at (the FINAL one) | |
| seed | INT | 10010–18446744073709550000 | — |
| passi_densi | INT | 4016–120 | Steps of the measuring trajectory. 40 is enough, 60 is more precise |
| cfg | FLOAT | 1.000–10 | As you will use it (Turbo: 1.0) |
| profilo | STRING | krea2_turbo_nvfp4 | File name inside profili/ |
| modalita | COMBO | accumula | accumula (accumulate) = averages with the other prompts; re-running the same prompt UPDATES its sample instead of adding one. sostituisci (replace) = start from scratch |
| modello_riferimentoopt | MODEL | Optional: e.g. Krea 2 FP8, to measure the error introduced by NVFP4 quantization |
