alt Hacker NewsI'm not sure what you mean by "deals in facts, not words" means.
Llm deal in vectors internally, not words. They explode the word into a multidimensional representation, and collapse it again, and apply the attention thingy to link these vectors together. It's not just a simple n:n Markov chain, a lot is happening under the hood.
And are you saying the syncophant behaviour was deliberately programmed, or emerged because it did well in training?

LLMs are not like an expert system representing facts as some sort of ontological graph. What's happening under the hood is just whatever (and no more) was needed to minimize errors on it's word-based training loss.
I assume the sycophantic behavior is part because it "did well" during RLHF (human preference) training, and part deliberately encouraged (by training and/or prompting) as someone's judgement call of the way to best make the user happy and own up to being wrong ("You're absolutely right!").
If you're not sure, maybe you should look up the term "expert system"?
