ComfyUI 0.37 changes MiniMax-H3 output with same seed and workflow
Solongtomegrandma · reddit · 2026-10-01
A Reddit user on the ComfyUI portable build reports that updates used to keep outputs identical when testing with the same PNG, workflow and seed. But after updating to 0.37, MiniMax-H3 video generation now produces totally different output.
They suspect the MiniMax-H3 VAE optimizations by kijai (PR #16187) and ask whether others see the same effect — i.e. whether updates can break same-workflow, same-seed reproducibility.
