Through my expertise in Python programming, I have conceived and implemented several projects related to Stable Diffusion.
Some of these resources are freely accessible to the community on GitHub.

This custom node is designed to simplify the creation of portrait-related prompts.

ComfyUI Prompt Composer

A set of combinable nodes to granularly structure and control generic prompts.

ComfyUI HiDiffusion

This set of 4 custom nodes enables the use of HiDiffusion within the ComfyUI working environment.
