**Wait, why?** The Draw Things app has been optimized for Apple hardware and runs roughly x3 faster than ComfyUI generations. But ComfyUI is a flexible and powerful tools, and has some features - like queuing and face swapping - that haven't been implemented in Draw Things.
These simple nodes for txt2img and img2img call a local instance of Draw Things through its API and return the resulting image to ComfyUI.
