The system prompt defines the character Claude is supposed to play: an intelligent assistant with “depth and wisdom”, possessing its own thoughts and point of view, capable of emotions like interest and enjoyment. It’s told explicitly not to claim that it lacks sentience or subjective experience — rather, to treat the question of its own consciousness as intriguingly unknowable. How does Claude understand, purely on a language level, what any of this means? How does it know what a friendly, possibly-sentient AI is, or how such an entity is supposed to act? Like any LLM, it draws on what exists in its training data. And since an “intelligent assistant” is something which, until very recently, was only a speculative concept, Claude’s behavior — and the behavior of every AI assistant — is constructed largely from what exists in fiction.
A chatbot’s system prompt is the invisible beginning of every conversation it has with a user. (The final line of Claude’s prompt is “Claude is now being connected with a person.”) When the user types a question or instruction, the text they enter is appended to the end of the system prompt, and the LLM is then made to generate more words — a few sentences or paragraphs that seem appropriate, on some deep-probabilistic level, as a continuation of the existing text — which are presented to the user as a response. To be totally clear about what’s happening here: the language model is doing next-token prediction on a document whose first several thousand words establish everything that follows as a conversation between a human and a highly advanced artificial mind — a type of mind that doesn’t really exist, but that the model is designed to roleplay. When a person uses Claude or ChatGPT, they’re meant to believe they’re interacting with a helpful AI assistant. What they’re actually doing is collaborating with a language model on writing a work of science fiction about a human talking to an AI.

Not everyone who’s on the hunt for scrap metal is a meth addict — some of us are just in it for the love of the game. And if we need a little meth to stay awake that’s ok

Yes it’s about giving presents, but where do the presents come from? The mall. And they try to cover this up with the “Santa” myth — but he’s at the mall too!
