Poor Man's Prompt Expansion for Stable Diffusion
* Various Stable Diffusion models massively benefit from prompt descriptions that contain
* additional descriptors. Much recent research has gone into training text generation models for
* expanding existing Stable Diffusion prompts with relevant and context appropriate descriptors.
* Since it isn't feasible to run LLMs and text generation models inside most users' web browsers
* at this time, I present my "Poor Man's Prompt Expansion Model". It uses a number of examples
* I've acquired from Fooocus and Hugging Face to generate completely random
* (though not context appropriate) prompt expansions.
