It also makes the LLM work better. If you’re rude to it it won’t want to help as much.

I understand what you're saying, which is that the response it generates is influenced by your prompt, but feel compelled to observe that LLMs cannot want anything at all, since they are software and have no motivations.

I'd probably have passed this over if it wasn't contextually relevant to the discussion, but thank you for your patience with my pedantry just the same.
