MiniMax H3 Open Weights Hit ComfyUI: Consumer GPUs Generate Video Locally

Suspicious_Pizza9529 · reddit · 2026-08-04

MiniMax H3 weights are now live on Hugging Face with native ComfyUI support. Thanks to dynamic VRAM optimization and pruning, VRAM requirements have dropped significantly, allowing consumer GPUs like the 4070ti/5070ti to generate full video with audio in under 2 minutes.

Community reports indicate its prompt adherence outperforms Wan 2.2. However, because the original context module is API-locked, whether running the base model locally without it causes major coherence issues remains an open question for testing.
