Why does google AI give different responses to different people?

Reddit r/ArtificialInteligence News

Summary

The author observes that Google AI gives different responses to different users for the same query, and explores the reasons behind this, referencing LLM non-determinism while noting personal consistency.

I saw this post and noticed when I google "what do worms eat", I get this normal response no matter how many times I keep asking the same question, different browsers, incognito mode, etc. But others in the thread showed that they got this weird, different answer about Rome for some reason. I have a surface level understand of how LLMs work by predicting the next most likely token or whatever, but I didn't realize that different people asking the exact same question word for word could get a different response. When I looked for an explanation, others mentioned that LLMs are non deterministic, but then why would I keep getting the same answer over and over?
