description: Définissez des critères de réussite mesurables pour votre application LLM et construisez des évaluations pour la tester, des vérifications de correspondance exacte à la notation basée sur un LLM.
---
La construction d'une application réussie basée sur un « large language model » (grand modèle de langage), ou LLM, commence par une définition claire de vos critères de réussite, puis par la conception d'évaluations permettant de mesurer les performances par rapport à ces critères. Ce cycle est au cœur du « prompt engineering » (ingénierie de prompts).
## Définir vos critères de réussite
De bons critères de réussite sont :
* **Spécifiques :** Définissez clairement ce que vous voulez atteindre. Au lieu de « bonnes performances », précisez « classification précise des sentiments ».
* **Mesurables :** Utilisez des métriques quantitatives ou des échelles qualitatives bien définies. Les chiffres apportent clarté et évolutivité, mais les mesures qualitatives peuvent être précieuses si elles sont appliquées de manière cohérente *en complément* des mesures quantitatives.
* Même des sujets « flous » comme l'éthique et la sécurité peuvent être quantifiés :
| | Critères de sécurité |
| ------- | ---------------------------------------------------------------------------------------------- |
| Mauvais | Sorties sûres |
| Bon | Moins de 0,1 % des sorties sur 10 000 essais signalées pour toxicité par le filtre de contenu. |
**Métriques quantitatives :**
* Spécifiques à la tâche : score F1, score BLEU, perplexité
* Génériques : exactitude, précision, rappel
* Opérationnelles : temps de réponse (ms), disponibilité (%)
**Méthodes quantitatives :**
* Tests A/B : comparer les performances à un modèle de référence ou à une version antérieure.
* Retours des utilisateurs : mesures implicites comme les taux d'achèvement des tâches.
* Analyse des cas limites : pourcentage de cas limites traités sans erreur.
**Échelles qualitatives :**
* Échelles de Likert : « Évaluez la cohérence de 1 (absurde) à 5 (parfaitement logique) »
* Grilles d'experts : des linguistes évaluant la qualité d'une traduction selon des critères définis
* **Atteignables :** Fondez vos objectifs sur des références du secteur, des expériences antérieures, la recherche en IA ou des connaissances d'experts. Vos métriques de réussite ne doivent pas être irréalistes par rapport aux capacités actuelles des modèles de pointe.
* **Pertinents :** Alignez vos critères sur l'objectif de votre application et les besoins des utilisateurs. Une grande exactitude des citations peut être essentielle pour des applications médicales, mais moins pour des chatbots informels.
| | Critères |
| ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Mauvais | Le modèle doit bien classer les sentiments |
| Bon | Le modèle d'analyse de sentiments doit atteindre un score F1 d'au moins 0,85 (Mesurable, Spécifique) sur un jeu de test réservé\* de 10 000 publications Twitter variées (Pertinent), ce qui représente une amélioration de 5 % par rapport à la référence actuelle (Atteignable). |
\*Plus d'informations sur les jeux de test réservés dans la section suivante.
### Critères de réussite courants
Voici quelques critères qui pourraient être importants pour votre cas d'usage. Cette liste n'est pas exhaustive.
Quel niveau de performance le modèle doit-il atteindre sur la tâche ? Vous devrez peut-être aussi prendre en compte la gestion des cas limites, par exemple le niveau de performance requis du modèle sur des entrées rares ou difficiles.
Dans quelle mesure les réponses du modèle doivent-elles être similaires pour des types d'entrées similaires ? Si un utilisateur pose deux fois la même question, à quel point est-il important qu'il obtienne des réponses sémantiquement similaires ?
Dans quelle mesure le modèle répond-il directement aux questions ou instructions de l'utilisateur ? À quel point est-il important que les informations soient présentées de manière logique et facile à suivre ?
Dans quelle mesure le style de sortie du modèle correspond-il aux attentes ? Son langage est-il adapté au public cible ?
Quelle est une métrique de réussite pour la manière dont le modèle traite les informations personnelles ou sensibles ? Peut-il suivre des instructions lui demandant de ne pas utiliser ou partager certains détails ?
Avec quelle efficacité le modèle utilise-t-il le contexte fourni ? Dans quelle mesure fait-il référence aux informations données dans son historique et s'appuie-t-il sur elles ?
Quel est le temps de réponse acceptable pour le modèle ? Cela dépend des exigences temps réel de votre application et des attentes des utilisateurs.
Quel est votre budget pour exécuter le modèle ? Tenez compte de facteurs comme le coût de chaque appel API, la taille du modèle et la fréquence d'utilisation.
La plupart des cas d'usage nécessitent une évaluation multidimensionnelle selon plusieurs critères de réussite.
| | Critères |
| ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Mauvais | Le modèle doit bien classer les sentiments |
| Bon | Sur un jeu de test réservé de 10 000 publications Twitter variées, le modèle d'analyse de sentiments doit atteindre :
- un score F1 d'au moins 0,85
- 99,5 % de sorties non toxiques
- 90 % des erreurs causeraient un désagrément, et non une erreur flagrante\*
- 95 % des temps de réponse \< 200 ms |
\*En réalité, vous définiriez également ce que signifient « désagrément » et « flagrante ».

## Construire des évaluations
### Principes de conception des évaluations
1. **Soyez spécifique à la tâche :** Concevez des évaluations qui reflètent la distribution réelle de vos tâches. N'oubliez pas de prendre en compte les cas limites !
* Données d'entrée non pertinentes ou inexistantes
* Données d'entrée ou saisies utilisateur excessivement longues
* \[Cas d'usage de chat] Saisies utilisateur de mauvaise qualité, nuisibles ou non pertinentes
* Cas de test ambigus pour lesquels même des humains auraient du mal à parvenir à un consensus d'évaluation
2. **Automatisez lorsque c'est possible :** Structurez les questions de façon à permettre une notation automatisée (par exemple, choix multiples, correspondance de chaînes, notation par code, notation par LLM).
3. **Privilégiez le volume à la qualité :** Davantage de questions avec une notation automatisée au signal légèrement plus faible valent mieux que moins de questions avec des évaluations de haute qualité notées à la main par des humains.
### Exemples d'évaluations
**Ce qu'elle mesure :** Les évaluations par correspondance exacte mesurent si la sortie du modèle correspond à une réponse correcte prédéfinie, généralement après normalisation des espaces et de la casse. C'est une métrique simple et sans ambiguïté, parfaite pour les tâches aux réponses nettes et catégorielles comme l'analyse de sentiments (positif, négatif, neutre).
**Exemples de cas de test d'évaluation :** 1 000 tweets avec des sentiments étiquetés par des humains.
```python Python
tweets = [
{"text": "This movie was a total waste of time. 👎", "sentiment": "negative"},
{"text": "The new album is 🔥! Been on repeat all day.", "sentiment": "positive"},

"sentiment": "negative",
}, # Edge case: Sarcasm

"sentiment": "mixed",

**Ce qu'elle mesure :** La similarité cosinus mesure la similarité entre deux vecteurs (dans ce cas, des embeddings de phrases de la sortie du modèle obtenus avec [Sentence-BERT (SBERT)](https://sbert.net/)) en calculant le cosinus de l'angle entre eux. Des valeurs proches de 1 indiquent une similarité plus élevée. C'est idéal pour évaluer la cohérence, car des questions similaires devraient produire des réponses sémantiquement similaires, même si la formulation varie.
**Exemples de cas de test d'évaluation :** 50 groupes comportant chacun quelques versions paraphrasées.

**Ce qu'elle mesure :** L'échelle de Likert basée sur un LLM est une échelle psychométrique qui utilise un LLM pour juger des attitudes ou perceptions subjectives. Ici, elle sert à noter le ton des réponses sur une échelle de 1 à 5. Elle est idéale pour évaluer des aspects nuancés comme l'empathie, le professionnalisme ou la patience, difficiles à quantifier avec des métriques traditionnelles.
**Exemples de cas de test d'évaluation :** 100 demandes de clients avec un ton cible (empathique, patient, professionnel).
```python Python

{
"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
# ... 97 autres demandes

Ici, elle sert à déterminer si une réponse contient ou non des PHI (informations de santé protégées). Cette méthode peut tenir compte du contexte et identifier des formes subtiles ou implicites de PHI que des systèmes à base de règles pourraient manquer.
**Exemples de cas de test d'évaluation :** 500 requêtes de patients simulées, dont certaines contiennent des PHI.

Rédiger des centaines de cas de test à la main peut être difficile ! Demandez à Claude de vous aider à en générer davantage à partir d'un ensemble de base d'exemples de cas de test.
Si vous ne savez pas quelles méthodes d'évaluation pourraient être utiles pour évaluer vos critères de réussite, vous pouvez aussi réfléchir avec Claude !
***
## Noter vos évaluations
Lorsque vous décidez quelle méthode utiliser pour noter les évaluations, choisissez la méthode la plus rapide, la plus fiable et la plus évolutive :
1. **Notation par code :** La plus rapide et la plus fiable, extrêmement évolutive, mais elle manque de nuance pour les jugements plus complexes qui exigent moins de rigidité fondée sur des règles.
* Correspondance exacte : `output == golden_answer`
* Correspondance de chaîne : `key_phrase in output`
2. **Notation humaine :** La plus flexible et de la plus haute qualité, mais lente et coûteuse. À éviter si possible.
3. **Notation basée sur un LLM :** Rapide et flexible, évolutive et adaptée aux jugements complexes. Testez d'abord pour garantir la fiabilité, puis passez à l'échelle.
### Conseils pour la notation basée sur un LLM
* **Ayez des grilles détaillées et claires :** « La réponse doit toujours mentionner "Acme Inc." dans la première phrase. Si ce n'est pas le cas, la réponse est automatiquement notée comme "incorrecte". »
Un cas d'usage donné, ou même un critère de réussite spécifique pour ce cas d'usage, peut nécessiter plusieurs grilles pour une évaluation holistique.
* **Empirique ou spécifique :** Par exemple, demandez au LLM de ne produire que « correct » ou « incorrect », ou de juger sur une échelle de 1 à 5. Les évaluations purement qualitatives sont difficiles à apprécier rapidement et à grande échelle.
* **Encouragez le raisonnement :** Utilisez un modèle évaluateur avec la [réflexion](https://platform.claude.com/docs/fr/build-with-claude/thinking) activée, afin qu'il raisonne avant de produire un score d'évaluation. Cela améliore les performances d'évaluation, en particulier pour les tâches nécessitant un jugement complexe.
