Sorties structurées

  • Les LLM produisent des sorties structurées seulement avec des directives explicites
  • Structures possibles :
    • Tableau
    • Liste
    • Paragraphe structuré
    • Format personnalisé

Schéma illustrant que si l'on demande une sortie structurée à ChatGPT, on obtient la structure demandée ; sinon, la réponse est aléatoire ou sans structure.
