This tutorial explains how to create a Q&A system using LangChain, OpenAI’s GPT-3.5-turbo, and LangChain Hub. It provides step-by-step instructions on integrating these tools to build a practical application that retrieves and answers questions based on information from a specific Wikipedia page.
Before starting, make sure you have Python 3.11 or higher and pip installed. You also need to install dependencies by running a specific command in your terminal. Additionally, you must set the OPENAI_API_KEY environment variable to authenticate with the OpenAI API by running another command in your terminal. Replace ‘your-openai-api-key’ with your actual OpenAI API key.
By the end of the tutorial, you will have a working example of how to use these tools to create a Q&A system. This guide aims to help users understand the process of building such a system and how to leverage the capabilities of LangChain, GPT-3.5-turbo, and LangChain Hub to develop practical applications.
