GLM is noticeably dumber with sages prompt. Which doesn't really come as a surprise, but I did try my best to go into this as unbiased as I could.
It's worse at keeping track of where my MC left her clothes for exhibitionism stories, it has the guy try to talk to girls that are explicitly described as mindless sluts, etc. I tested for a few rerolls and base GLM consistently gets it, while sage's prompt makes it shit the bed.
