In this tutorial, we implement an end-to-end MiniMax-H3 video generation workflow using ComfyUI as a headless inference backend. We configure the environment around GPU memory, disk capacity, model precision, resolution, duration, sampling strategy, and multiple generation modes, while dynamically selecting an appropriate weight profile based on the available hardware. We install and launch ComfyUI programmatically, download the required diffusion, text-encoder, video-VAE, and audio-VAE weights from Hugging Face, and communicate with the running server through its HTTP and WebSocket APIs. We also construct the ComfyUI execution graph directly in Python, validate node schemas against the live /object_info endpoint, and support text-to-video, first- and last-frame-conditioned generation, and reference-image-conditioned generation. By combining automated model setup, schema-aware graph construction, joint video-audio decoding, progress monitoring, and output collection, we create a reproducible pipeline for experimenting with MiniMax-H3 without relying on the graphical ComfyUI interface.
