Where to place Hunyuan Video weights on Windows
13B open-weights text-to-video and image-to-video foundation model producing coherent 720p motion sequences inside native ComfyUI video nodes.
Place the primary `.safetensors` or `.gguf` weight file inside `models/diffusion_models/` inside your ComfyUI directory, or point extra_model_paths.yaml to your existing shared models drive.
After moving the file, press **R** on the ComfyUI Studio canvas (or click Refresh) so the loader dropdown lists the new checkpoint immediately without restarting the server.
Recommended loader nodes and sampler settings
- **Precision & Memory:** BF16, FP8, or GGUF. Cards at the lower end of 12 GB–24 GB (with GGUF / FP8 offload) should pair this model with FP8 or GGUF quantization and VAE Decode (Tiled).
- **Sampler & Scheduler:** FlowMatchEulerDiscreteScheduler, 20–30 steps. Wire the model output into KSampler and connect the matching CLIP and VAE streams.
- **Installer:** If you have not set up the desktop environment yet, get the Windows build at /download.

FAQs
Which folder does Hunyuan Video go into in ComfyUI?
Put Hunyuan Video inside `models/diffusion_models/` in your ComfyUI installation, then press R on the canvas to refresh node dropdowns.
Can I run Hunyuan Video on an 8 GB NVIDIA GPU?
Yes — use FP8 or GGUF Q4/Q5 weights via ComfyUI-GGUF and keep tiled VAE decoding enabled so peak VRAM stays under 8 GB.
