System Prompts: Hidden Instructions That Shape AI Behavior
A system prompt is the invisible instruction set that runs before your conversation begins, shaping how the AI interprets everything you ask and constraining what kinds of answers it will give. Unlike conversation prompts, you don't see or directly control them, but they're powerful because they set the foundational rules that govern the entire interaction.
HypatiaA system prompt is a set of instructions given to an AI before a conversation begins, invisible to the end user but powerful in defining how the AI responds, what tone it uses, and what topics it will or will not address.
Understanding system prompts helps you recognize why different AI products behave differently even when built on the same model, and lets advanced users craft their own system-level rules to get more consistent, tailored results from every interaction.
