How to Build a RAG System Using LangChain, Ragas, and Neptune
LangChain provides composable building blocks to create LLM-powered applications, making it an ideal framework for building RAG systems. Developers can integrate components and APIs of different vendors into coherent applications. Evaluating a RAG system’s performance is crucial to ensure high-quality responses and robustness. The Ragas framework offers a large number of RAG-specific metrics as well as capabilities for generating dedicated evaluation datasets. neptune.ai makes it easy for RAG developers to track evaluation metrics and metadata, enabling them to analyze and compare different system configurations. The experiment tracker can handle large amounts of data, making it well-suited for quick iteration and
