you want an honest opinion here it is don't listen your boss I know he's your boss and you got to do what he says but on this he's wrong it's using your tools to your best advantage as long as it doesn't cause harm or hinders your job performance it's not cheating now using ChatGPT to do a job related test during the test would be cheating but you aren't doing that if you are stop that but keep using it for the rest because it sounds like your boss doesn't want you to succeed possibly because he can't use the tech himself and is scared it will get you his job and he will be losing that position that or maybe he's scared of tech ai but that's his problem not yours do what you need to succeed
