Yesterday I tried Gemini "Can you find the origin of this story I remember from 10+ years ago? Here's three paragraphs of what I recall"

"Yeah, it sounds like a very common copypasta back in the early 2010's, related to XYZ"

"So... uhh... provide me a link please"

"I can't provide links"

"You're a search engine"

"I don't have a current connection to the Internet."

"Well can you give me any examples of anything even vaguely resembling this topic?"

"Yeah, like in the Reddit thread titled ABC, where $two_paragraphs_of_description"

"I can't find that Reddit thread"

"I'm sorry! I hallucinated that it was a common thing, but actually you told me a unique thing that you just made up."

"This sounds like a contradiction. Where did you pull the information about the Reddit thread from?"

"I can't link it, but it was on the sub _____ and it was titled _______ and it talked about your thing at length"

"When I google that I find nothing"

"Sorry! I hallucinated that I knew the link. Actually there is no link, there is no discussion like that, and the thing you provided was totally unique."

I then proceeded to try Googling various permutations of the topics for the thread it brought up, which kept giving me 10 nonsense results, and a grouped collection of Reddit posts that it would not expand on / separate.
