Spectrum: Faster MiniMax H3 Video Generation in ComfyUI
A ComfyUI node that speeds up MiniMax H3 video generation by predicting transformer outputs mathematically and skipping selected computation steps.
The Spectrum Apply MiniMax H3 ComfyUI node allows you to speed up MiniMax H3 video synthesis by approximating transformer hidden states using a Chebyshev ridge regression model, while maintaining identical results for the generation heads, audio, and video reconstruction at each step. In the README I openly discuss the quality/speed tradeoffs and provide examples of when things go wrong (e.g., anatomy warping and audio loss with aggressive parameter values).
Why a vibe-coder should care
If you’re a ComfyUI user looking to speed up your MiniMax H3 video synthesis workflow without having to change how you currently operate, then this node can be easily inserted prior to the sampler to achieve significant speedups! Just follow the instructions in the README to learn about how to safely use this node (i.e., with non-aggressive parameters) versus more aggressively.
