Hey everyone,
I’ve been testing the MiniMax-H3 Ref2VA workflow with the new acceleration LoRA (PTD + RefAsymOPD), which cuts steps from 40 down to 6–8 while surprisingly improving quality and realism.
You can find the model weights and custom nodes here: taobao-content-ai/MiniMax-H3-PTD-RefAsymOPD-LoRAs Why it stands out
Unlike typical distillation methods that sacrifice quality for speed, RefAsymOPD is optimized for reference-to-video, reducing background blur and AI artifacts. The sharpness and background plausibility at just 6–8 steps are incredible, feeling way less “plastic” than expected.
Available Variants & Usage
It is a drop-in replacement compatible with both Diffusers and ComfyUI. If you already have your MiniMax-H3 environment set up, you just need to swap the checkpoint file name.
Getting a 5x speedup while maintaining (or even improving) full-quality results feels like pure magic. Highly recommended for open-source devs!
