LangChain in Action: Develop LLM-Powered Applications Overview

In the fast-paced world of AI, LangChain stands out as a powerful framework for building applications that fully utilise large language models (LLMs). This hands-on course, Lang Chain in Action: Develop LLM-Powered Applications, empowers you to master the skills and knowledge needed to unlock the full potential of Lang Chain. You’ll start by diving into the basics and quickly progress to advanced techniques. As you move through the course, you will explore a variety of topics, including memory management, OpenAI function calling, retrieval-augmented generation (RAG), and microservice architecture for LLM applications. By the end of this course, you will have the expertise to create sophisticated LLM-powered applications that can turn data into actionable insights.

Learning Outcomes

  • Understand the foundational concepts of LangChain and its significance in LLM-powered applications.
  • Develop and implement basic to advanced chains in LangChain for efficient data processing.
  • Utilise callbacks in LangChain to enhance application performance and interactivity.
  • Manage memory effectively within LangChain to optimise application efficiency.
  • Implement OpenAI function calling within LangChain to integrate powerful language models.
  • Apply Retrieval Augmented Generation (RAG) techniques to improve the accuracy and relevance of generated content.
  • Develop and deploy agents within LangChain for automating complex tasks.
  • Leverage the Indexing API to efficiently organise and retrieve information in LLM applications.
  • Understand and implement LangSmith and LangChain Expression Language (LCEL) for advanced LLM application development.
  • Design and deploy a microservice architecture tailored for LLM-powered applications.

Who Is This Course For

This Lang Chain course is ideal for developers, data scientists, and AI enthusiasts who already have a foundational understanding of machine learning.
