This handbook presents a comprehensive and systematic framework for artificial intelligence in motor insurance, grounded in real-world production deployment. It documents the design, development, and operationalization of the MARSAIL (Motor AI Recognition Solution Artificial Intelligence Laboratory) ecosystem, one of Thailand’s earliest large-scale AI deployments for automotive insurance. The handbook integrates perception, multimodal reasoning, and production infrastructure into a cohesive intelligence stack for vehicle risk assessment, claims processing, and underwriting workflows. Core contributions include domain-adapted transformer architectures for structured visual understanding, relational vehicle representation, multimodal document intelligence, hierarchical attention refinement, and knowledge-enhanced model distillation. Beyond model innovation, the handbook emphasizes scalable pipelines, MLOps integration, and efficiency-focused engineering to ensure deployment-ready, production-grade AI systems. Over four years of iterative research and engineering, the handbook codifies a practical blueprint for translating cutting-edge AI research into robust, interpretable, and scalable solutions in high-stakes industrial environments.
