Prompting for a source wouldn’t satisfy me until I could trust that the AI wasn’t hallucinating. After all, if GPT can make up facts about things like legal precedent or well documented events, why would I trust that its citations are legitimate?

And if the suggestion is that the person asking for the information double check the cited sources, maybe that’s reasonable to request, but it somewhat defeats the original purpose.

Bing might be doing things differently though, so you might be right in your assessment on that front. I haven’t played with their AI yet.
