 If you have enough VRAM, please select `cuda` in the `cache_device` option, which can bring faster inference, but will increase VRAM slightly. If you have limited VRAM, please select `cpu` in the `cache_device` option, which do not increase VRAM, but will make inference slower slightly.

 ### Compile Model
 To use Compile Model node, simply add `Compile Model` node to your workflow after `Load Diffusion Model` node or `TeaCache` node. Compile Model uses `torch.compile` to enhance the model performance by compiling model into more efficient intermediate representations (IRs). This compilation process leverages backend compilers to generate optimized code, which can significantly speed up inference. The compilation may take long time when you run the workflow at first, but once it is compiled, inference is extremely fast. The usage is shown below:
