Googles Ai has quoted several of you here when asking about proof marks, pressures and dates after feeding it pics and drilling down. But trying to identify people and records of possible provenance has caused lots of hallucinations and silly compliments. Definitely start with telling it no fluffy stuff just stick to facts you can source
Google AI has improved remarkably in the last year or so...but the best path to success to is to present the same query to at least three AI systems and look for inconsistencies between responses.
Always ask for links and sources as part of your information request, and if not provided, force the issue with a 2nd request.
One of the things that I find interesting is what sources the various AIs have access to. They are not all the same, and that can impact results.
