System prompt
System prompt refers to basic instructions given to AI before starting a conversation. AI’s tone and rules are set here.
System prompts are basic instructions given to the AI before a conversation with the user begins, and are usually invisible to the user. It can be compared to the script and acting instructions given to actors before a play begins, and what character should speak and what not to do is written here.
Because even the same model becomes a completely different service depending on the system prompt, it is used as a key means of designing identity and rules when creating an AI chatbot or service. The nature of the product is determined by including the answer tone, prohibitions, company information, response procedures, etc.
However, system prompts are not strong rules but only high-priority instructions, so there are cases where they are ignored or the content is leaked due to clever guidance. It is important to understand that it is not a security device.
✅ Why it matters
- Even with the same model, you can freely design the nature of the service and tone of voice
- Create consistent response quality by setting prohibitions and response rules
- It is the fastest and cheapest customization method in AI service development
⚠️ Limits and debates
- Instructions may be ignored or bypassed due to clever guidance
- There are cases where hidden information is leaked, so it is dangerous to keep confidential information
- If the instructions are long and complicated, the AI may miss some parts.
