Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | Auto-detects FM vs EDM by sigma_max | |
| steps | INT | 201–1000 | — |
| scheduler_type | COMBO | ddrk_auto | 9 options: ddrk_auto, ddrk_cosine, ddrk_beta, ddrk_flow_linear, ddrk_flow_cosmos, ddrk_fewstep, +3 |
| flow_shift | FLOAT | 3.01–10 | — |
| warmup_steps | INT | 00–5 | — |
| beta_a | FLOAT | 2.00.1–10 | Shape parameter A, used only by ddrk_beta. Higher A front-loads larger steps at high sigma and leaves finer steps near sigma 0. Ignored by every other scheduler. |
| beta_b | FLOAT | 1.00.1–10 | Shape parameter B, used only by ddrk_beta. Raising B above ~2 shifts resolution toward high sigma and leaves a large final step, which is usually undesirable. A=2, B=1 gives Karras-like monotonically shrinking steps. |
| auto_optimize | BOOLEAN | true | Auto-select scheduler & flow_shift for FM few-step. Disable for full manual control. |
