Frequently Asked Questions
What is a System Prompt?
A System Prompt (or System Instruction) is the initial directive given to an AI. It sets the behavior, personality, and constraints *before* the user asks a question. It is the most powerful lever for controlling LLM output.
Why use a structured format?
LLMs are improved by clarity. Breaking instructions into "Role", "Task", "Context", and "Format" reduces ambiguity and hallucinations. This structure (often called the CO-STAR method or similar) is an industry standard for prompt engineering.
Does this work for all models?
Yes! This structure is universal. Whether you are using GPT-4, Claude 3.5, or Llama 3, explicit instructions about role and output format will always improve performance.
