1. Start a ComfyUI server.

   • lanuch from source:

   cd ComfyUI
   python3 main.py --cpu --use-pytorch-cross-attention
   

   • lanuch from comfy-cli:

   comfy launch -- --cpu --use-pytorch-cross-attention
   

2. Prepare a standard workflow in ComfyUI.

   

3. Add OpenVINO Node.

   

4. Connect OpenVINO Node with Model/LoRa Loader.

   

5. Run workflow. Please notice it may need an additional warm-up inference after switching new model.
