ComfyUI Node
Apply HyperFlow H3 Advanced (Ablations)
HyperFlow advanced: gate and sigma-grid overrides for ablations. Defaults reproduce the released model exactly.

Inputs (10)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | The MiniMax-H3 diffusion model to patch. Chain once. | |
| hyperflow_file | COMBO | The ComfyUI-converted HyperFlow weights (models/hyperflow). | |
| strength | FLOAT | 1.000–2 | Adapter strength. 1.0 is the released model. |
| lora_mode | COMBO | bypass | bypass: run-time additive (sharp). merge: folded into the weights (low VRAM, softer on quantized bases). |
| variant | COMBO | auto | Build to fetch when downloading: auto (default) matches the detected base; full = non-pruned base; pruned = backbone-only for pruned/curve bases. Ignored when the file is already on disk. |
| download_if_missing | BOOLEAN | false | Download the chosen variant from drbaph/Hyperflow-Comfyui into models/hyperflow when missing. Requires internet. |
| gate | FLOAT | -1.00-1–2 | Blend of the endpoint embedding. -1 (default) reads the gate from the weights file; any other value overrides it (ablation). |
| sigmas | STRING | Custom raw sigma grid, comma separated, must start <= 1 and end at exactly 0 (e.g. the 9 default points). Empty = the grid stored in the weights file (the trained 8-step grid). Ablation use only. | |
| verbose | BOOLEAN | false | Log the applied modules and the per-step (t, r) context. |
| experimental_curve_refitopt | BOOLEAN | false | Experimental checkpoint-bound fit; gate/strength/sigma overrides disable the refit and keep backbone-only behavior. |
