LLM Apps with Langchain

There has been an explosion in the use of Large Language Models (LLMs) in the last year with a new model being released almost every week. These LLMs have proved to be general reasoning engines capable of solving multiple types of problems from simple text summarization to complex code generation and even agentic workflows. Langchain has emerged as the most popular library to use when building LLM-powered applications and in this course, we will explore components like Langchain-Core, LangServe, and LangSmith to build, deploy, and track the performance of our apps. In the end, you will have a strong understanding of the challenges in building LLM apps and make use of the LangChain library to create LLM solutions.

The course

Learn and apply skills with real-world projects.

Who is it for?
  • Software engineers and developers who want to learn how to work with LLMs and use their capabilities to design, build, and operate complex projects.

  • Engineering Managers and other Technology professionals who want to understand reference architectures when working with LLMs and guide their teams on approach and tool choices.

  • Anybody interested in building LLM apps and wants to understand challenges with this new technology and understand ways to fix, monitor and deploy LLM apps.

  • Basic level of familiarity with programming (typically in Python) and ability to work in a notebook or IDE environment (e.g. Google Colab, VS Code)

  • Ability to read and understand how to work with documented libraries (e.g. publicly available APIs)

  • Basic understanding of how Large Language Models (LLMs) work with some experience in writing and running prompts
