I feel like 4o is an insufferable know it all. Someone needs to reprogram its default tone. I think they want to act like the model is improving but all they're really doing it making it more verbose. I'm on to you, Sam. I know what you're up to. 4o is just 5 3.5 Turbos in a big trench coat, and 2 of them have just been assigned a prompt like "take the answer the other 3 worked out, and make it sound deeper".
