Multi Document Agentic RAG: a Walkthrough

Agentic Retrieval-Augmented Generation (RAG) represents an evolution in information management by enhancing traditional RAG systems with a higher level of autonomy that allows for decision-making and action-taking without constant supervision. Unlike conventional RAG systems that merely retrieve relevant data for language models to generate responses, Agentic RAG employs intelligent strategies to break tasks into manageable steps and utilize necessary tools to generate nuanced and well-thought-out replies. The system is exemplified by a multi-document Agentic RAG designed for automotive needs, which can diagnose car issues, suggest solutions, and organize maintenance by extracting and indexing data from JSON files using tools like LlamaIndex for logic management, memory buffers for conversational context, and Vector Databases for information retrieval. The integration of OpenAI’s GPT-4 for response generation and sentence transformers for embeddings supports the agent's reasoning capabilities, while the use of specialized API interfaces enhances the agent's ability to interact with data sources. Through an Agent reasoning loop facilitated by LlamaIndex components, the system demonstrates effectiveness in delivering contextually accurate answers by orchestrating tools and databases efficiently, as illustrated by its ability to provide comprehensive car maintenance guidance based on mileage.
