LangSmith
LangSmith est la plateforme de surveillance, de test et de débogage de production de LangChain pour les applications LLM, fournissant la couche d'observabilité dont les équipes d'IA ont besoin pour créer des produits d'IA fiables. Il capture chaque appel LLM, action d'agent et exécution de chaîne avec un contexte complet, permettant aux développeurs de tracer les échecs, de comparer les sorties du modèle, d'exécuter des tests de régression et de surveiller les performances de production en temps réel. LangSmith s'intègre parfaitement à LangChain et LangGraph, mais fonctionne également avec n'importe quel framework LLM, ce qui en fait le choix standard pour les équipes qui ont besoin de confiance dans la qualité de leurs applications d'IA.
