LLM Enhanced T5 prompt (Flux,SD3)

This workflow will take any prompt and significantly enhance it using an LLM to provide a very detailed prompt designed specifically for T5 natural language prompting (Flux, SD3).

This workflow was only possible for me by the impressive work of Reddit user u/glibsonoran for creating the Plush-for-ComfyUI nodes and u/Relative_Bit_7250 for his talented work creating the Custom GPT "Image Prompt Generator" which heavily guided my LLM instructions here.

You can use this with a variety of LLMS, but I recommend Groq simply because you can get a free API key that will do all you need for this workflow. Pay particular attention to setting up the API key environment variable, see here: https://github.com/glibsonoran/Plush-for-ComfyUI#requirements
