 | `LanPaint_NumSteps` | 0-20 | Reasoning iterations per denoising step ("thinking depth"). Easy task: 1-2. Hard task: 5-10 |
 | `LanPaint_Lambda` | 0.1-50 | Content alignment strength (higher = stricter). Recommend 6.0 |
 | `LanPaint_StepSize` | 0.1-1.0 | The StepSize of each thinking step. Recommend 0.1 for most cases, 0.5 for some difficult cases. |
-| `LanPaint_cfg_BIG` | 0-20 | CFG scale used when aligning masked and unmasked region (higher = better alignment). Recommend 8 for seamless inpaint (i.e limbs, faces), 0-1 for character consistency (i.e multiple view) |
+| `LanPaint_cfg_BIG` | -20-20 | CFG scale used when aligning masked and unmasked region (positive value tends to ignores promts, negative value enhances prompts.).
