Getting Started with LangChain

# Getting Started with LangChain LangChain is a powerful framework for developing applications powered by language models. In this guide, we'll explore how to build sophisticated AI applications using LangChain's core components. ## What is LangChain? LangChain is a framework designed to simplify the creation of applications using large language models (LLMs). It provides a standard interface for chains, agents, and memory, making it easier to build complex AI applications. ## Core Components ### 1. Chains Chains are the core of LangChain. They combine multiple components to create a sequence of operations. ### 2. Agents Agents use LLMs to determine which actions to take and in what order. ### 3. Memory Memory gives LLMs the ability to remember previous interactions. ### 4. Vector Stores Vector stores allow you to store and search through unstructured data. ## Getting Started Let's build a simple question-answering system using LangChain. This guide covers the fundamentals of building AI applications with LangChain and provides practical examples for getting started.
