En tant qu'architecte solution senior ayant déployé des systèmes IA pour le patrimoine culturel chinois pendant quatre ans, je peux affirmer sans détour : la restauration des bâtiments anciens représente l'un des défis techniques les plus complexes en traitement de document multimodal. Les archives des instituts de restauration contiennent des siècles deCalligraphie, des rapports de dommage en caractères traditionnels, des photographies en basse résolution de artifacts dégradés, et des données de spectrométrie qu'aucun modèle unique ne peut traiter efficacement.

Dans cet article, je détaille l'architecture que nous avons construite chez HolySheep AI pour orchestrer Gemini 2.5 Flash pour la reconnaissance visuelle, Kimi pour le parsing de longs documents historiques, et un système de monitoring SLA en temps réel. Vous disposerez de code production-ready, de benchmarks mesurés, et d'une analyse de rentabilité comparée aux fournisseurs occidentaux.

Architecture du Système : Orchestration Multi-Modèle pour le Patrimoine

Notre architecture sépare clairement les responsabilités en trois couches distinctes : ingestion, traitement, et sortie. Cette séparation permet une mise à l'échelle horizontale et une optimisation des coûts par tâche.

Performance Benchmarks : Résultats Mesurés en Production

Nos tests ont été réalisés sur un volume de 10 000 requêtes par modèle, avec des images de bâtiments historiques en condiciones réelles. Voici les résultats comparatifs :
