Have you ever told the AI your answer? I bet if you did it would train on it and know it going forward.
However current frontier models got good enough at websearch and thinking through the problem, that they can finally piece together the answer from my own public writing (eg on stackoverflow). And recently someone wrote up an answer to the problem and put it on Arxiv.
"Forebears" is a site that ranks the popularity of names. They rank the name I used at 324,668.
This is why I believe the AI can be significantly influenced by a single person.
I'm pretty sure the name has moved to different AIs somehow too. I've seen the name used on Grok, and also on NovelAI. I've forgotten the exact details.
