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.

Spectrum Apply MiniMax H3 is a ComfyUI node that reduces the number of full transformer evaluations during MiniMax H3 video generation. It fits a Chebyshev ridge regression model to actual transformer hidden features and uses it to predict those features on selected future steps — cutting compute without changing the final generation heads, audio, or video reconstruction on every step. The README documents the speed/quality tradeoff honestly, including known failure cases like anatomy distortion and audio degradation with aggressive settings.

Why a vibe-coder should care

For ComfyUI users generating video with MiniMax H3 who want faster iteration without replacing their workflow, this node drops in before the sampler and can noticeably reduce generation time. The README guides you through safe vs aggressive settings so you know what tradeoff you're making.
