Concepts Fondamentaux
System Prompt
An instruction block sent before the conversation that configures model behavior.
The system prompt is a privileged message — separate from the user turn — that sets the model's persona, constraints, and task context. It is consumed as input tokens on every request, so long system prompts can significantly increase costs at scale. Effective system prompts are concise but precise.
