I use chatGPT quite a bit, and for the most part while it's been pretty good at sounding professional but whenever I've asked it to communicate like a real person would speak or to tell a joke it hasn't really sounded authentic or funny. ChatGPT 4o seems a lot better at this though. I asked it to tell me a joke in the style of Louis CK and this is what it came up with and it's amazing;
"You ever notice how people say 'sleep like a baby'? Really? Like a baby? Have you ever met a baby? Babies don't sleep! They wake up every two hours screaming and demanding attention. You want to sleep like a baby? Try downing three espressos and letting a raccoon loose in your bedroom. That's baby sleep for you. I want to sleep like a cat. Those guys have it figured out. They sleep 18 hours a day, wake up just long enough to eat and give you a look that says, 'You’re still here?' Then they go right back to sleep. That’s the life, man. I want that!"
