System prompt
What is System prompt?
Instructions provided to an AI model before the user conversation begins. Used to set the model's role, tone, constraints, and behavior for a specific application.
Example in practice
A product team building a customer-facing AI assistant would write a system prompt defining the assistant's persona, allowed topics, response length, and escalation instructions — invisible to end users but controlling every response.
