Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | MODEL INPUT • Purpose: The diffusion model to patch. • Output: Returns the patched model ready for sampling. | |
| extrapolation_mode | COMBO | linear | EXTRAPOLATION ALGORITHM • Linear: Faster, uses 2 steps history. Best for standard workflows. • Quadratic: Smoother, uses 3 steps history. Best for non-linear schedules. ⭐ Recommended: linear |
| skip_strategy | COMBO | conservative | SKIP STRATEGY • Conservative: Run N-1 steps, Skip 1. Safest for Images (15-50 steps). • Aggressive: Run 1 step, Skip N-1. Best for Audio/Video (1000+ steps). ⭐ Recommended: conservative (Images), aggressive (Audio/Video) |
| skip_interval | INT | 22–100 | SKIP INTERVAL • Conservative Mode: e.g., 3 = Run 2, Skip 1. • Aggressive Mode: e.g., 5 = Run 1, Skip 4. • Warning: High intervals on low step counts will cause artifacts. ⭐ Recommended: 2 |
| start_percentage | FLOAT | 0.100–1 | START PROTECTION % • Purpose: Wait until this % of generation is done before skipping. • Why: Crucial for allowing the model to set the initial structure. ⭐ Recommended: 0.1 (Wait 10%) |
| end_percentage | FLOAT | 0.900–1 | END PROTECTION % • Purpose: Stop skipping after this % of generation. • Why: Ensures the model renders high-fidelity fine details at the end. ⭐ Recommended: 0.9 (Stop at 90%) |
