There is really no other way to think of them, in terms of reliability, than lying bastards. I mean, ChatGPT is very fun and quite useful, but think of it. Anybody that has played with it for even an hour has been confidently lied to by it, multiple times. If you keep friends around that treat you like that, you need a better friend picker! (Maybe an AI could help.)
ChatGPT has no concept of truth or lie. It’s a language model that uses statistical models to predict what to say next. Your assumptions about its intentions reflect only your bias.
