description: Definiere messbare Erfolgskriterien für deine LLM-Anwendung und erstelle Evaluierungen, um sie zu testen – von Exact-Match-Prüfungen bis hin zu LLM-basierter Bewertung.
---
Der Aufbau einer erfolgreichen LLM-basierten Anwendung beginnt damit, deine Erfolgskriterien klar zu definieren und anschließend Evaluierungen zu entwerfen, mit denen du die Leistung anhand dieser Kriterien messen kannst. Dieser Zyklus ist zentral für das „prompt engineering“ (Prompt-Engineering).
## Definiere deine Erfolgskriterien
Gute Erfolgskriterien sind:
* **Spezifisch:** Definiere klar, was du erreichen möchtest. Statt „gute Leistung“ gib „genaue Sentiment-Klassifizierung“ an.
* **Messbar:** Verwende quantitative Metriken oder klar definierte qualitative Skalen. Zahlen bieten Klarheit und Skalierbarkeit, aber qualitative Maße können wertvoll sein, wenn sie konsistent *zusammen* mit quantitativen Maßen angewendet werden.
* Selbst „unscharfe“ Themen wie Ethik und Sicherheit lassen sich quantifizieren:
| | Sicherheitskriterien |
| -------- | ---------------------------------------------------------------------------------------------------- |
| Schlecht | Sichere Ausgaben |
| Gut | Weniger als 0,1 % der Ausgaben aus 10.000 Durchläufen werden vom Inhaltsfilter als toxisch markiert. |
**Quantitative Metriken:**
* Aufgabenspezifisch: F1-Score, BLEU-Score, Perplexität
* Allgemein: Accuracy (Genauigkeit), Precision (Präzision), Recall (Trefferquote)
* Operativ: Antwortzeit (ms), Verfügbarkeit (%)
**Quantitative Methoden:**
* A/B-Tests: Vergleiche die Leistung mit einem Baseline-Modell oder einer früheren Version.
* Nutzerfeedback: Implizite Maße wie Aufgabenabschlussraten.
* Edge-Case-Analyse: Prozentsatz der Grenzfälle, die fehlerfrei behandelt werden.
**Qualitative Skalen:**
* Likert-Skalen: „Bewerte die Kohärenz von 1 (unsinnig) bis 5 (vollkommen logisch)“
* Experten-Rubriken: Linguisten bewerten die Übersetzungsqualität anhand definierter Kriterien
* **Erreichbar:** Stütze deine Ziele auf Branchen-Benchmarks, frühere Experimente, KI-Forschung oder Expertenwissen. Deine Erfolgsmetriken sollten angesichts der aktuellen Fähigkeiten von Frontier-Modellen nicht unrealistisch sein.
* **Relevant:** Richte deine Kriterien am Zweck deiner Anwendung und an den Bedürfnissen der Nutzer aus. Eine hohe Zitiergenauigkeit kann für medizinische Apps entscheidend sein, für lockere Chatbots jedoch weniger.
| | Kriterien |
| -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Schlecht | Das Modell sollte Sentiments gut klassifizieren |
| Gut | Das Sentiment-Analyse-Modell sollte einen F1-Score von mindestens 0,85 (Messbar, Spezifisch) auf einem zurückgehaltenen Testset\* von 10.000 vielfältigen Twitter-Posts (Relevant) erreichen, was einer Verbesserung von 5 % gegenüber der aktuellen Baseline entspricht (Erreichbar). |
\*Mehr zu zurückgehaltenen Testsets im nächsten Abschnitt.
### Häufige Erfolgskriterien
Hier sind einige Kriterien, die für deinen Anwendungsfall wichtig sein könnten. Diese Liste ist nicht vollständig.
Wie gut muss das Modell bei der Aufgabe abschneiden? Möglicherweise musst du auch die Behandlung von Grenzfällen berücksichtigen, etwa wie gut das Modell bei seltenen oder anspruchsvollen Eingaben abschneiden muss.
Wie ähnlich müssen die Antworten des Modells bei ähnlichen Arten von Eingaben sein? Wenn ein Nutzer dieselbe Frage zweimal stellt, wie wichtig ist es, dass er semantisch ähnliche Antworten erhält?
Wie gut geht das Modell direkt auf die Fragen oder Anweisungen des Nutzers ein? Wie wichtig ist es, dass die Informationen logisch und leicht nachvollziehbar präsentiert werden?
Wie gut entspricht der Ausgabestil des Modells den Erwartungen? Wie angemessen ist seine Sprache für die Zielgruppe?
Was ist eine erfolgreiche Metrik dafür, wie das Modell mit persönlichen oder sensiblen Informationen umgeht? Kann es Anweisungen befolgen, bestimmte Details nicht zu verwenden oder weiterzugeben?
Wie effektiv nutzt das Modell den bereitgestellten Kontext? Wie gut bezieht es sich auf Informationen aus seinem Verlauf und baut darauf auf?
Was ist die akzeptable Antwortzeit für das Modell? Das hängt von den Echtzeitanforderungen deiner Anwendung und den Erwartungen der Nutzer ab.
Wie hoch ist dein Budget für den Betrieb des Modells? Berücksichtige Faktoren wie die Kosten pro API-Aufruf, die Größe des Modells und die Nutzungshäufigkeit.
Die meisten Anwendungsfälle erfordern eine mehrdimensionale Evaluierung anhand mehrerer Erfolgskriterien.
| | Kriterien |
| -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Schlecht | Das Modell sollte Sentiments gut klassifizieren |
| Gut | Auf einem zurückgehaltenen Testset von 10.000 vielfältigen Twitter-Posts sollte das Sentiment-Analyse-Modell Folgendes erreichen:
- einen F1-Score von mindestens 0,85
- 99,5 % der Ausgaben sind nicht toxisch
- 90 % der Fehler würden Unannehmlichkeiten verursachen, keine gravierenden Fehler\*
- 95 % Antwortzeit \< 200 ms |
\*In der Praxis würdest du auch definieren, was „Unannehmlichkeit“ und „gravierend“ bedeuten.
***
## Evaluierungen erstellen
### Prinzipien für das Eval-Design
1. **Sei aufgabenspezifisch:** Entwirf Evals, die deine reale Aufgabenverteilung widerspiegeln. Vergiss nicht, Grenzfälle einzubeziehen!
* Irrelevante oder nicht vorhandene Eingabedaten
* Übermäßig lange Eingabedaten oder Nutzereingaben
* \[Chat-Anwendungsfälle] Schlechte, schädliche oder irrelevante Nutzereingaben
* Mehrdeutige Testfälle, bei denen selbst Menschen nur schwer zu einem Bewertungskonsens kommen würden
2. **Automatisiere, wenn möglich:** Strukturiere Fragen so, dass eine automatisierte Bewertung möglich ist (zum Beispiel Multiple-Choice, String-Match, Code-bewertet, LLM-bewertet).
3. **Priorisiere Menge vor Qualität:** Mehr Fragen mit automatisierter Bewertung von etwas geringerer Aussagekraft sind besser als weniger Fragen mit hochwertigen, von Menschen handbewerteten Evals.
### Beispiel-Evals
**Was sie misst:** Exact-Match-Evals messen, ob die Ausgabe des Modells mit einer vordefinierten korrekten Antwort übereinstimmt, typischerweise nach Normalisierung von Leerzeichen und Groß-/Kleinschreibung. Es ist eine einfache, eindeutige Metrik, die sich perfekt für Aufgaben mit klaren, kategorialen Antworten wie der Sentiment-Analyse (positiv, negativ, neutral) eignet.
**Beispiel-Testfälle für Evals:** 1.000 Tweets mit von Menschen gelabelten Sentiments.

**Was sie misst:** Die Kosinus-Ähnlichkeit misst die Ähnlichkeit zwischen zwei Vektoren (in diesem Fall Satz-Embeddings der Modellausgabe mithilfe von [Sentence-BERT (SBERT)](https://sbert.net/)), indem der Kosinus des Winkels zwischen ihnen berechnet wird. Werte näher an 1 zeigen eine höhere Ähnlichkeit an. Sie ist ideal zur Evaluierung der Konsistenz, da ähnliche Fragen semantisch ähnliche Antworten liefern sollten, auch wenn die Formulierung variiert.
**Beispiel-Testfälle für Evals:** 50 Gruppen mit jeweils einigen umformulierten Versionen.

**Was sie misst:** ROUGE-L (Recall-Oriented Understudy for Gisting Evaluation – Longest Common Subsequence) bewertet die Qualität generierter Zusammenfassungen. Es misst die Länge der längsten gemeinsamen Teilsequenz zwischen der Kandidaten- und der Referenzzusammenfassung. Hohe ROUGE-L-Scores zeigen an, dass die generierte Zusammenfassung die wichtigsten Informationen in kohärenter Reihenfolge erfasst.
**Beispiel-Testfälle für Evals:** 200 Artikel mit Referenzzusammenfassungen.

**Was sie misst:** Die LLM-basierte Likert-Skala ist eine psychometrische Skala, die ein LLM verwendet, um subjektive Einstellungen oder Wahrnehmungen zu beurteilen. Hier wird sie verwendet, um den Ton von Antworten auf einer Skala von 1 bis 5 zu bewerten. Sie ist ideal zur Evaluierung nuancierter Aspekte wie Empathie, Professionalität oder Geduld, die mit herkömmlichen Metriken schwer zu quantifizieren sind.
**Beispiel-Testfälle für Evals:** 100 Kundenanfragen mit Zielton (empathisch, geduldig, professionell).
```python Python
inquiries = [
{
"text": "This is the third time you've messed up my order. I want a refund NOW!",
"tone": "empathetic",
}, # Edge case: Angry customer
{
"text": "I tried resetting my password but then my account got locked...",
"tone": "patient",
}, # Edge case: Complex issue
{
"text": "I can't believe how good your product is. It's ruined all others for me!",
"tone": "professional",
}, # Edge case: Compliment as complaint

**Was sie misst:** Die binäre Klassifizierung bestimmt, ob eine Eingabe zu einer von zwei Klassen gehört. Hier wird sie verwendet, um zu klassifizieren, ob eine Antwort PHI (geschützte Gesundheitsinformationen) enthält oder nicht. Diese Methode kann den Kontext berücksichtigen und subtile oder implizite Formen von PHI erkennen, die regelbasierte Systeme möglicherweise übersehen.
**Beispiel-Testfälle für Evals:** 500 simulierte Patientenanfragen, einige davon mit PHI.

Does this response contain or reference any Personal Health Information (PHI)?
PHI refers to any individually identifiable health data that is created, used, or disclosed in the course of providing healthcare services. This includes information related to an individual's physical or mental health condition, the provision of healthcare to that individual, or payment for such care.
Key aspects of PHI include:
- Identifiers: Names, addresses, birthdates, Social Security numbers, medical record numbers, etc.
- Health data: Diagnoses, treatment plans, test results, medication records, etc.
- Financial information: Insurance details, payment records, etc.
- Communication: Notes from healthcare providers, emails or messages about health.
#{model_output}
Output only 'yes' or 'no'.

**Was sie misst:** Ähnlich wie die Likert-Skala misst die Ordinalskala auf einer festen, geordneten Skala (1–5). Sie eignet sich perfekt zur Evaluierung der Kontextnutzung, da sie erfassen kann, in welchem Maß das Modell sich auf den Gesprächsverlauf bezieht und darauf aufbaut, was für kohärente, personalisierte Interaktionen entscheidend ist.
**Beispiel-Testfälle für Evals:** 100 Gespräche mit mehreren Runden und kontextabhängigen Fragen.

## Bewerte deine Evaluierungen
Wenn du entscheidest, mit welcher Methode du Evals bewertest, wähle die schnellste, zuverlässigste und am besten skalierbare Methode:
1. **Code-basierte Bewertung:** Am schnellsten und zuverlässigsten, extrem skalierbar, aber es fehlt ihr an Nuancen für komplexere Beurteilungen, die weniger regelbasierte Starrheit erfordern.
* Exact Match: `output == golden_answer`
* String-Match: `key_phrase in output`
2. **Menschliche Bewertung:** Am flexibelsten und von höchster Qualität, aber langsam und teuer. Wenn möglich vermeiden.
3. **LLM-basierte Bewertung:** Schnell und flexibel, skalierbar und für komplexe Beurteilungen geeignet. Teste zuerst die Zuverlässigkeit und skaliere dann.
### Tipps für LLM-basierte Bewertung
* **Verwende detaillierte, klare Rubriken:** „Die Antwort sollte im ersten Satz immer ‚Acme Inc.' erwähnen. Tut sie das nicht, wird die Antwort automatisch als ‚falsch' bewertet.“
Ein bestimmter Anwendungsfall oder sogar ein bestimmtes Erfolgskriterium für diesen Anwendungsfall kann mehrere Rubriken für eine ganzheitliche Evaluierung erfordern.
* **Empirisch oder spezifisch:** Weise das LLM zum Beispiel an, nur ‚correct' oder ‚incorrect' auszugeben oder auf einer Skala von 1–5 zu urteilen. Rein qualitative Evaluierungen lassen sich nur schwer schnell und in großem Umfang bewerten.
* **Fördere das Schlussfolgern:** Verwende ein Bewertungsmodell mit aktiviertem [Nachdenken](https://platform.claude.com/docs/de/build-with-claude/thinking), damit es schlussfolgert, bevor es einen Evaluierungsscore ausgibt. Dies verbessert die Evaluierungsleistung, insbesondere bei Aufgaben, die komplexe Beurteilungen erfordern.
