MiniMax-H3 INT8 FLF & Reference Video Workflows Collection
A collection of optimized ComfyUI workflows for MiniMax-H3, designed for high-speed video generation using INT8 quantization, Sol-Attn, Spectrum acceleration, and MiniMax-H3-Turbo-Lora (Experimental).
These workflows provide optimized pipelines for:
- First-Last-Frame (FLF) video generation
- Reference-to-Video (R2V) generation
- High-speed INT8 inference
Optimized for the ComfyUI-compatible MiniMax-H3 model package.
