1.50K viewsOtherTechnology

I asked it for a list of restaurants in my area using google maps and it said there is a restaurant (Mug and Bean) in my area and even used a real address but this restaurant is not in my town. Its only in a neighboring town with a different street address

It isn’t actually “making up” an answer, in that it isn’t some kind of deception or the like (that would require intent, and it does not have intent, it’s just a *very* fancy multiplication program).

It is collecting together data that forms a grammatically-correct sentence, based on the sentences you gave it. The internal calculations which figure out whether the sentence is grammatically correct have zero ability to actually know whether the statements it makes are *factual* or not.

The technical term, in “AI” design, for this sort of thing is a “hallucination.”
