Frontier video models are useless if only the studio box can run them. FastVideo shipped FastH3 Trim, a pruned MiniMax H3 with 42 transformer blocks instead of 50, sampled in eight steps, about 4.2× smaller than base H3.
The int8 ComfyUI pack is aimed at cards with as little as 8 GB of VRAM while keeping picture and sound together. If your team prototypes on home machines, this is the path that makes H3 a daily tool instead of a cloud-only treat.
