Ein System-Prompt ist ein wichtiger Bestandteil eines Large Language Models (LLMs) wie GPT-3.5, GPT-4, Claude 3 Opus und den darauf basierenden KI-Chatbots wie ChatGPT.
In diesem Lexikon-Eintrag erfährst du, was ein System-Prompt ist, welche Arten dieser Prompts es gibt und welche Zwecke sie erfüllen. Zudem findest du eine interaktive Sammlung von über 20 System-Prompts bekannter Chatbots.
1. Definition
Ein System-Prompt ist der initiale Befehl, der einem LLM gegeben wird. Er dient als Rahmen und Anleitung für die KI, an der sie sich bei seinen Antworten orientieren kann.
System-Prompts werden bei jedem Befehl von Endnutzern an ein LLM „mitgesendet", unabhängig davon, wie der Befehl aussieht. Sie sind durch Endnutzer zudem nicht änderbar, löschbar und in der Regel auch nicht einsehbar.
Und nein:
Natürlich verbrauchen diese keine Token deines Token-Kontingents, selbst wenn diese sehr lang sind.
2. Arten von System-Prompts
Wenn man von „System-Prompt" spricht, können zum einen System-Prompts bekannter Chatbots gemeint sein oder die System-Prompts, die du als Entwickler selbst festlegen kannst.
In diesem Abschnitt schauen wir uns beide einmal an:
2.1 System-Prompts bei ChatGPT & Co.
Alle bekannten KI-Chatbots wie ChatGPT, Claude, Microsoft Copilot oder Google Gemini haben System Prompts (Beispiele dafür findest du unter Punkt 3).
Diese System-Prompts erfüllen viele verschiedene Zwecke:
- Sie verhindern, dass ein Chatbot diskriminierende, sexistische, beleidigende oder schädliche Antworten gibt.
- Sie definieren die Funktionen, die das LLM nutzen kann (z. B. Web-Browsing, Code Interpreter oder Bildgenerierung)
- Sie legen die Antwortlänge fest (so werden in der ChatGPT-App z. B. kürzere Antworten gegeben als in der Browser-App)
- Sie beschränken ein LLM auf bestimmte Aufgaben oder Themen
- Sie geben dem LLM mehr Kontext mit, damit es bessere Antworten geben kann
- Sie legen die „Persönlichkeit" des Chatbots fest
2.2 System-Prompts als Entwickler selbst festlegen
Wenn du eine eigene App oder Anwendung entwickelst und dafür die OpenAI API, die Claude API oder andere LLM-APIs verwendest, kannst du in der Regel auch einen System-Prompt festlegen.
Hier ein Beispiel für einen API-Call der OpenAI API, bei der ein System-Prompt mitgesendet wird:
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-3.5-turbo",
messages=[
{"role": "system", "content": "Du bist ein hilfreicher Assistent."},
{"role": "user", "content": "Wer hat die Fußball-WM 2022 gewonnen?"},
{"role": "assistant", "content": "Argentinien hat die Fußball-WM 2022 gewonnen."},
{"role": "user", "content": "Wo wurde die WM ausgetragen?"}
]
)Auch hier erfüllen System Prompts ähnlichen Funktionen wie bei den großen Chatbot-Anbietern.
Du legst damit Eigenschaften wie Persönlichkeit, Ziel, Antwortformat oder Antwortbeispiele fest.
Wenn du z. B. einen Chatbot entwickeln möchtest, der bei der Linux-Administration hilft, könntest du folgenden System Prompt nutzen:
Ich möchte, dass du als Linux-Terminal agierst. Ich werde Befehle eingeben und du antwortest mit dem, was das Terminal anzeigen sollte. Antworte nur mit der Terminalausgabe in einem einzigartigen Codeblock und nichts anderem. Verzichte auf jegliche Erklärungen oder Kommentare vor oder hinter der Ausgabe.3. System-Prompts bekannter Chatbots
Die folgende interaktive Galerie enthält über 20 vollständige System-Prompts von bekannten KI-Tools, darunter ChatGPT (3.5, 4, 4.5 und GPTs), Claude, Grok, Gemini, Microsoft Copilot, Perplexity, Cursor, GitHub Copilot und viele weitere.

4. Herausforderungen bei System-Prompts
Die Erstellung von System-Prompts kann herausfordernd sein. Einige häufige Schwierigkeiten umfassen:
- Prompt Injections: Durch bestimmte Methoden kann es möglich sein, System Prompts auszuhebeln, sodass ein Chatbot seine Anweisungen ignoriert.
- Abwehrmaßnahmen gegen Prompt Injections: Abwehrmaßnahmen gegen Prompt Injection können ebenfalls problematisch sein, weil sie dafür sorgen können, dass die Leistung des LLMs verschlechtert wird.
- Kosten: Je länger der System Prompt ist, desto teurer ist jede einzelne Abfrage an das LLM.
- Zu vage oder allgemeine Formulierung: Wenn ein System Prompt zu vage oder zu allgemein formuliert ist, kann dass dafür sorgen, dass die Antwortqualität bei spezifischeren Anforderungen abnimmt oder mehr Prompting seitens Endnutzern erfordert.
- Zu spezifische Formulierung: Wenn ein System Prompt zu spezifisch formuliert ist, kann dies dazu führen, dass die Antwortqualität bei allen anderen Anfragen, die sich nicht auf diese Spezialisierung beziehen, abnimmt.
- Diversität & Positive Diskriminierung: Durch Anweisungen in System Prompts, die zu mehr Diversität und weniger Benachteiligung bestimmter Menschengruppen führen sollen, kann es zu historischen Ungenauigkeiten oder einer Benachteiligung anderer Menschengruppen kommen. So war es zum Start von Google Gemini z. B. schwierig, Bilder von einem schwarzen Lehrer oder einem weißen Tierarzt zu bekommen.
