The question is very important. What if you ask/tell an AI "I need a 2 bedroom vacation rental in Park City for a trip this fall". If you only get Airbnb results you are missing a lot of the true answer.
That's a "problem" of the harness that you use those, not a question of the model. The model can "know" things like "Linus Torvalds created Linux" but things like "Is X available in Y right now?" it obviously cannot, leading to this being a completely different thing compared to "just knowing" something and providing references to "how it knows".
