System Prompt

A System Prompt is a hidden, foundational instruction given to a language model that defines its persona, rules, and constraints before any user input. The system prompt typically establishes who the model is ("you are a helpful customer service agent for Acme Corp"), what it can and cannot do ("never discuss competitors"), the desired tone, output format requirements, and any safety guardrails. Most modern chat APIs (OpenAI, Anthropic, Google) accept a system prompt as a distinct role separate from user messages. Well-engineered system prompts can dramatically improve consistency, but they are also the primary target of prompt-injection attacks attempting to extract or override them. Examples of leaked system prompts from popular AI products have appeared online, showing both the craft and the vulnerability of these instructions. System prompts are governed assets in every mature enterprise AI program. AI governance teams version, audit, and review system prompts as part of AI compliance and responsible AI deployments.
