system prompt

Hidden instructions that set the model's role and rules before the user talks.

First Seen

2022–23

Context

The system prompt is injected at the start of the conversation context, invisible to the user but shaping how the model behaves. Developers use it to set persona, enforce safety rules, and provide background knowledge. Its hidden nature makes it a target for prompt injection attacks.
