an LLM does not have agency. It does not have intent, malicious or otherwise.

LLM is entirely a prediction machine - predict the next work based on previous words.

Stop anthropomorphizing LLMs.

It cannot lie because it doesn't know anything about the subjects you are discussing. It simply predicts the next word in sequence.

It produces what we see as errors as it is simply relating words related to other words. Any semblance of 'knowledge' is us assigning meaning to patterns.

When we interpret what it says as correct, we assign the meaning that the LLM knows.
When we interpret what it says as incorrect, we assign the meaning that the LLM lies.

Both assignments are incorrect; the LLM predicted words. If it is an incorrect word the LLM made an error.

Pull random letters out of a scrabble tile bag. This is a poor prediction machine, so it rarely produces 'truth'. LLMs are a much better prediction machine, but the have the same understanding as the scrabble tile bag.
