Introduction
In this blog, we’ll explore the powerful concept of Retrieval-Augmented Generation (RAG) and how it enhances the capabilities of large language models by integrating real-time, external knowledge sources. You’ll also learn how to build an end-to-end application that leverages this approach for practical use.
We’ll begin by understanding what RAG is, how it works, and why it’s gaining popularity for building more accurate and context-aware AI solutions. RAG combines the strengths of information retrieval and text generation, enabling language models to reference external, up-to-date knowledge bases beyond their original training data, making outputs more reliable and factually accurate.
As a practical demonstration, we’ll walk through building a custom RAG application that can intelligently query information from your own PDF documents. To achieve this, we’ll use the AWS Bedrock Llama 3 8B Instruct model, along with the LangChain framework and Streamlit for a user-friendly interface.
Key Technologies For End-to-End RAG Solution

a. Interactive front–end for the application.
b. Simple yet powerful framework for building Python web
apps.
2. LangChain:
a. Framework for creating LLM–powered workflows.
b. Provides seamless integration with AWS Bedrock.
3. AWS Bedrock:
a. State–of–the–art LLM platform.
b. Powered by the highly efficient Llama 3 8B Instruct model.
