Description
Welcome to the LangChain course. LangChain is a framework designed to build applications powered by large language models (LLMs). It provides tools and abstractions to make it easier to integrate LLMs into applications, enabling tasks like question answering, text generation, retrieval-augmented generation (RAG), chatbots, and more.LangChain – Use CasesHere are some of the use cases of LangChain:Question Answering: Build systems that answer questions by retrieving relevant information and generating answers using LLMs.Chatbots: Create conversational agents that can maintain context across interactions.Retrieval-Augmented Generation (RAG): Combine retrieval of relevant documents with text generation for more accurate and context-aware responses.Text Summarization: Generate summaries of long documents or articles.Code Generation: Build tools that generate code based on natural language descriptions.Personal Assistants: Create virtual assistants that can perform tasks like scheduling, email drafting, or information retrieval.Course LessonsLangChain – Introduction1.
