What makes GPT-4 so much better than GPT-3.5 and competitors?

Any ideas? Obviously it's not a simple answer. Size, training set matter, but don't explain it. I suspect there is a set of models, algorithms which filter wrong and abusive responses.

I find it hard to believe that this would be "if it got hacked it could create diplomacy issues", because I don't think that Facebook is setting up any type of special infrastructure to deal with political figures on their platform.
