Mongodb rag langchain. I have saved the OpenAI API key in key_params.
Mongodb rag langchain One of the most powerful applications enabled by LLMs is sophisticated question-answering (Q&A) chatbots. RAG is a significant advancement in AI, particularly in natural language processing, and combining these technologies allows for the creation of powerful AI-driven In addition to deploying MongoDB Atlas on the cloud, you use the Atlas CLI to deploy self-contained MongoDB instances on your local machine. When combined with an LLM, this approach enables relationship-aware retrieval and multi-hop reasoning. By implementing these tools, developers can ensure their AI chatbots deliver highly accurate and contextually relevant answers. Embeddings are created for the small chunks. LangChain simplifies building the chatbot logic, while MongoDB Atlas' vector database capability provides a powerful platform for Jun 4, 2025 · MongoDB is a document-based NoSQL database that offers a flexible and scalable foundation for building RAG applications. These are applications that can answer questions about specific source information. Oct 31, 2024 · RAG_Pattern. First, you'll learn what RAG is. Then you'll learn about several AI integrations and frameworks that can help you build a RAG application. Environment Setup You should export two environment variables, one being your MongoDB URI, the other being your OpenAI API KEY. The goal is to load documents from MongoDB, generate embeddings for the text data, and perform semantic searches using both LangChain and LlamaIndex frameworks. Jun 6, 2024 · I showed you how to connect your MongoDB database to LangChain and LlamaIndex separately, load the data, create embeddings, store them back to the MongoDB collection, and then execute a semantic search using MongoDB Atlas vector search capabilities. 304 In the notebook we will demonstrate how to perform Retrieval Augmented Generation (RAG) using MongoDB Atlas, OpenAI and Langchain. About. py file. This tutorial demonstrates how to implement GraphRAG by using MongoDB Atlas and LangChain. View the GitHub repo for the implementation code. This starter template implements a Retrieval-Augmented Generation (RAG) chatbot using LangChain and MongoDB Atlas. From there, those medium size chunks are split into small chunks. Sep 18, 2024 · In this article, we've explored the synergy of MongoDB Atlas Vector Search with LangChain Templates and the RAG pattern to significantly improve chatbot response quality. Using Atlas Vector Search for RAG Unit Overview. RAG combines AI language generation with knowledge retrieval for more informative responses. Feb 14, 2024 · %pip install pymongo %pip install pypdf %pip install langchain %pip install langchain_community %pip install langchain_openai %pip install langchain_core. MongoDB Atlas is a fully-managed cloud database available in AWS, Azure, and GCP. I have saved the OpenAI API key in key_params. . GraphRAG is an alternative approach to traditional RAG that structures your data as a knowledge graph instead of as vector embeddings. Its native JSON-like document structure and advanced features such as full-text search, Atlas Vector Search, and seamless integration with cloud services make it particularly well-suited for handling unstructured or semi Dec 3, 2024 · By leveraging the retrieval-augmented generation (RAG) architecture with LangChain and Azure OpenAI, we demonstrated how vector stores are essential for LLM applications. These applications use a technique known as Retrieval Augmented Generation, or RAG. 2. While vector-based RAG finds documents that are semantically similar to the query, GraphRAG finds connected entities to the query and traverses the relationships in the graph to retrieve relevant information. When you specify the connection string parameter, you can specify your local deployment connection string instead GraphRAG is an alternative approach to traditional RAG that structures data as a knowledge graph of entities and their relationships instead of as vector embeddings. Building a retrieval system involves searching for and returning the most relevant documents from your vector database to augment the LLM with. In this unit, you'll build a retrieval-augmented generation (RAG) application with LangChain and the MongoDB Python driver. RAG Based Chat-bot using Langchain and MongoDB Atlas. In order to use OpenAIEmbeddings, we need to set up our OpenAI API key. This template performs RAG using MongoDB and OpenAI. It does a more advanced form of RAG called Parent-Document Retrieval. To retrieve relevant documents with Atlas Vector Search, you convert the user's question into vector embeddings and run a vector search query against your data in Atlas to find documents with the most similar embeddings. If you do not have a MongoDB URI, see the Setup Mongo section at the bottom for instructions on how to do so. If you do not have a key, you can create one here. This notebook covers how to MongoDB Atlas vector search in LangChain, using the langchain-mongodb package. In this guide, I’ll walk you through building a RAG chatbot using MongoDB as the database, Google Cloud Platform (GCP) for deployment, and Langchain to streamline retrieval and rag-mongo. The system processes PDF documents, splits the text into coherent chunks of up to 256 characters, stores them in MongoDB, and retrieves relevant chunks based on a prompt Users utilizing earlier versions of MongoDB Atlas need to pin their LangChain version to <=0. MongoDB Atlas. It supports native Vector Search, full text search (BM25), and hybrid search on your MongoDB document data. In this form of retrieval, a large document is first split into medium sized chunks. This starter template implements a Retrieval-Augmented Generation (RAG) chatbot using LangChain, MongoDB Atlas, and Render. It provided a clear, step-by-step approach to setting up a RAG application, including database creation, collection and index configuration, and utilizing LangChain to construct a RAG chain and application. 0. This Python project demonstrates semantic search using MongoDB and two different LLM frameworks: LangChain and LlamaIndex. This project implements a Retrieval-Augmented Generation (RAG) system using LangChain embeddings and MongoDB as a vector database. The LangChain MongoDB integration supports both Atlas clusters and local Atlas deployments. Sep 18, 2024 · This guide has simplified the process of incorporating memory into RAG applications through MongoDB and LangChain. btjjazurvqwmwustsapwktgvenjasyimwipltbualxzcrgbrdnv
