Inputs (13)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| enabled | BOOLEAN | true | — |
| preset | COMBO | balanced | quality: real step after every forecast. balanced: up to 2 forecasts in a row in the later half. fast: 2 early / 3 late (more drift). |
| warmup_steps | INT | 51–100 | Initial steps always run on the model (composition, text layout, sampler detection). |
| tail_actual_steps | INT | 20–20 | Final steps always run on the model. |
| degree | INT | 31–8 | — |
| ridge_lambda | FLOAT | 0.100–10 | — |
| blend_weight | FLOAT | 0.500–1 | Chebyshev share; remainder is 2-point linear extrapolation. |
| max_history | INT | 82–32 | — |
| forecast_space | COMBO | auto | Video forecast space. auto: features for deterministic samplers, denoised for noise-injecting ones. Audio always uses denoised. |
| history_storage | COMBO | system_ram | 2 options: system_ram, vram |
| validate | BOOLEAN | false | Also run the model on forecast steps and print forecast error (no speed-up). |
| debug | BOOLEAN | false | — |
