Generative AI & LLMs
System prompt
A high-priority instruction that sets an AI assistant's role, rules, or behavior.
Example
A system message tells the assistant to be concise and never reveal confidential information.
Why it matters
It gives a product consistent operating instructions across different user requests.
You'll hear it
“The assistant is set up to answer briefly and ask before taking action.”
Can you control it?
Sometimes
Sometimes. Some products or workflows let you influence a system prompt, while others keep it fixed or manage it automatically. Check the settings and documentation for the tool you are using.
Common questions
- Can the rules be kept completely secret just by including them here?
- No. Hidden instructions are not a reliable place to store passwords or other secrets.
- Does high priority guarantee perfect obedience?
- No. Conflicting material or system mistakes can still lead to unwanted behavior.
- Can two apps use the same AI with different system instructions?
- Yes. Different instructions can make their tone, limits and behavior noticeably different.
