Exactly, and all of this is a simple matter of having multiple models trained on different instances of the entire public internet and determining whether their outputs contradict each other or a web search.
I wonder how they prevented search engine results from contradicting data found through web search before LLMs became a thing?
They didn’t really have to before LLM. Search engine results, in the heyday we’re backlink driven. You could absolutely search disinformation and find it. But if you searched for a credible article on someone, chances are more people would have links to the good article than the disinformation. However, conspiracy theories often leaked through into search results. And in that case they just gave you the web pages and you had to decide for yourself.
