How to run it

Use ComfyUI at Q4 GGUF. The big text encoder is loaded to encode your prompt, then offloaded before generation, which is why peak VRAM stays near the backbone size rather than the sum of every file.

FAQ

Can Nvidia DGX Spark (128GB) run HunyuanVideo?

Yes. HunyuanVideo runs on Nvidia DGX Spark (128GB) at Q4 GGUF (~16 GB of ~112 GB usable).

How much VRAM does HunyuanVideo need?

Nvidia DGX Spark (128GB) has room to spare. At Q4 GGUF the realistic peak is ~16 GB of VRAM, versus ~60 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~8 GB, much slower.

What do I use to run HunyuanVideo locally?

HunyuanVideo runs in ComfyUI. It loads as a video diffusion checkpoint plus its text encoder and VAE, not a single chat command.
