The blog discusses how Retrieval Augmented Generation (RAG) can be combined with Large Language Models (LLMs) to improve claim processing in insurance. RAG integrates Atlas Vector Search and LLMs, allowing insurers to leverage proprietary data and make their models context-aware. The architecture involves organizing data in MongoDB collections, creating a Vector Search index on the array, and passing the prompt and retrieved documents to the LLM as context. This approach offers speed, accuracy, flexibility, natural interaction, and improved accessibility to unstructured data. It can also serve additional personas and use cases within an organization such as customer service, underwriting, and self-service options for customers.
