Wildcards and dynamic prompts are a killer feature for getting diversity. You can have ChatGPT output long lists of options and save them as text to pull from, rather than putting the OR options in the prompt. For instance, here’s just a snippet of my 100 line “hair_color_natural_hightlights.txt” wildcard file:

chestnut brown with sun-kissed golden highlights
dark blonde with naturally blended caramel highlights
auburn with subtle coppery undertones and honey highlights
jet black with hints of espresso brown and warm burgundy highlights
chocolate brown with natural honey and toffee highlights
ash brown with delicate pearl-toned highlights
light brown with sunlit blonde highlights

One question though, are you sure you have the dynamic prompts extension enabled in A111? These all look very similar, and the fact that the OR statement is in the prompt metadata still makes me wonder. Typically, the “brunette | ginger | blonde” would get resolved by the dynamic prompt processor before generation, and the image metadata would only show the single selected term by itself.
