It's decent for generating ideas or names for fiction. I've used it for tabletop stuff a couple of times to give me NPC names or lists of personality traits, and it's good sometimes for breaking writers block when I get stuck on some detail and I can't figure out what word I want to use or what to name something. You can usually get it to give you some sort of okay suggestions, but the volume of ideas is usually enough to spark a better idea for me. The only weird thing I've noticed is that GPT4 (or whatever flavor bing/copilot is currently using) REALLY likes alliteration to a degree that is downright corny. It's kinda weird but sort of funny honestly.
