ComfyUI Prompt Expansion

Dynamic prompt expansion, powered by GPT-2 locally on your device.

Based on my testing, it's evident that incorporating additional keywords generated by GPT-2 notably improves the quality of the resulting images.

Many thanks to the authors of the Fooocus project for generously providing most of the code.
