gguf quantized version of wan video
- drag gguf to >
./ComfyUI/models/diffusion_models - drag t5xxl-um to >
./ComfyUI/models/text_encoders - drag vae to >
./ComfyUI/models/vae

workflow
- for i2v model, drag clip-vision-h to >
./ComfyUI/models/clip_vision - run the .bat file in the main directory (assume you are using gguf pack below)
- if you opt to use **fp8 scaled umt5xxl** encoder (if applies to any fp8 scale t5 actually), please use cpu offload (switch from default to cpu under device in gguf clip loader; won't affect speed); btw, it works fine for both **gguf umt5xxl** and **gguf vae**
- drag any demo video (below) to > your browser for workflow

review
pigis a lazy architecture for gguf node; it applies to all model, encoder and vae gguf file(s); if you try to run it in comfyui-gguf node, you might need to manually addpigin it's IMGARCHLIST (under loader.py); easier than you edit the gguf file itself; btw, model architecture which compatible with comfyui-gguf, includingwan, should work in gguf node- 1.3b model: t2v, vace gguf is working fine; good for old or low end machine
run it with diffusers🧨 (alternative 1)

- wan2.1-v5-vace-1.3b: except block weights, all in
f32status (avoid triggering time/text embedding key error for inference usage)
