I just started writing my first chapter, and using the same beats, I had 3 different models generate the chapter. They are almost identical, except for a word or phrase here and there. Did I do something wrong? I expected them each to have a different style or voice, maybe start the scene a little differently, so i could choose which sounded most like me, and which created a story that fit my vision. But they are pretty much the same! Is this normal?
