Heyy guys!

Thanks

poor7 gave a poor answer, I am afraid.

this is my understanding:
sai is stablity ai - predifined prompt extensions provided by Stability AI
mre - prompt extensions developed by the Fooocus-MRE project (some kind of advanced Fooocus, not maintained for 6 months afaik)
mk - prompt extensions sourced from the work by another person - https://github.com/K3nt3L/MK-Styles/tree/main - huge repo of styles

I hope this helps ... devs, please correct if false.
