MiniMax H3 Tuning Guide: Benchmarks of Sage Attention vs. Spectrum Nodes
dassiyu · reddit · 2026-08-23
A Reddit user compared three acceleration node setups for MiniMax H3 on an RTX 5090:
- Sage Attention + 4-step LoRA: 6 mins, best overall balance.
- ComfyUI-Kitchen + 4-step LoRA: 5 mins, fastest speed.
- ComfyUI-Kitchen + Spectrum (25 steps): 12-15 mins, best quality (especially for lip-sync).
The author recommends the first setup for daily use and the third for high-quality outputs.
