MiniMax-H3 Turbo LoRAs for ComfyUI
This repository contains MiniMax-H3 Turbo and few-step LoRAs converted and optimized for ComfyUI.
These LoRAs accelerate MiniMax-H3 video and synchronized-audio generation by reducing the required number of sampling steps.
Update — HyperFlow 8-Step LoRAs
Four HyperFlow 8-step MiniMax-H3 LoRAs are now included.
They are derived from the original HyperFlow release by Video Rebirth:
HyperFlow is an 8-step MiniMax-H3 LoRA designed for the MiniMax-H3 T2VA, FL2VA and Ref2VA workflows.
The upstream HyperFlow implementation uses its own fixed 8-step sigma schedule. For these ComfyUI conversions, the recommended manual sigma sequence is:
1.0, 0.9939097854, 0.9842874953, 0.9660637197, 0.9230769231, 0.8349423898, 0.6968520491, 0.4687533149, 0.0
This is a nine-point sigma sequence defining eight denoising intervals.
HyperFlow files
| File | Variant | Purpose |
|---|---|---|
| minimax_h3_hyperflow_8step_v1.0_comfyui_bf16.safetensors | Full BF16 | Full-size ComfyUI HyperFlow 8-step conversion. |
| minimax_h3_hyperflow_8step_v1.0_comfyui_bf16_resized_avg_rank_20_bf16.safetensors | Resized BF16, avg rank 20 | Compact resized version of the full HyperFlow ComfyUI conversion. |
| minimax_h3_hyperflow_8step_v1.0_comfyui_pruned_bf16.safetensors | Pruned BF16 | HyperFlow 8-step conversion for the pruned/curve-form MiniMax-H3 base. |
| minimax_h3_hyperflow_8step_v1.0_comfyui_pruned_bf16_resized_avg_rank_20_bf16.safetensors | Pruned resized BF16, avg rank 20 | Compact resized HyperFlow version for the pruned/curve-form MiniMax-H3 base. |
Use the non-pruned files with the corresponding full MiniMax-H3 base and the pruned files with the compatible pruned/curve-form base.

When using the original Video Rebirth implementation, follow the upstream HyperFlow scheduler and loader rather than replacing its built-in schedule manually.
Update — TaoMate 3-Step EMA and VDN-H3 8-Step Extracts (experimental)
TaoMate FL2VA 3-step EMA
Newly added LoRA, located in the experimental/ folder:
minimax_h3_taomate_fl2va_3step_ema_comfyui.safetensors
Manual recommended sigmas: 3-step 1.0, 0.961165, 0.853333, 0.0
4-step 1.0, 0.970874, 0.907249, 0.640000, 0.0
VDN-H3 8-step extracts
Three LoRAs extracted from VDN-H3 8 step:
- minimax_h3_dmd_ref2va_8step_turbo_pruned.safetensors
- minimax_h3_dmd_fl2va_8step_turbo_pruned.safetensors
- minimax_h3_dmd_8step_turbo.safetensors
The main 8-step LoRA works on both FL2VA and Ref2VA. If you are running a pruned base, choose the pruned version that corresponds to your base — the pruned versions need their own matching pruned base.
