About This Udemy Course

The following is the full official course description for ChatGPT and LangChain: The Complete Developer's Masterclass as published on Udemy by instructor Stephen Grider:

You've found the most advanced, most complete, and most intensive masterclass online for learning how to integrate LangChain and ChatGPT into production-ready applications!

Thousands of engineers have learned how to build amazing applications using ChatGPT, and you can too. This course uses a time-tested, battle-proven method to make sure you understand exactly how ChatGPT works, and is the perfect pathway to help you get a new job as a software engineer working on AI-enabled apps.

The difference between this course and all the others: you will go far beyond the basics of simple ChatGPT prompts, and understand how companies are integrating text generation into their apps today.

___________

ChatGPT is being used across industries to enhance applications with text generation. But with this new feature comes many challenges:

  • Building complex text generation pipelines that incorporate outside information
  • Creating reusable configuration components that can be reassembled in different ways
  • Applying user feedback (like upvotes/downvotes) to enhance ChatGPT's output
  • Wiring in observability and tracing to see how users are interacting with your AI
  • Generate text performantly using distributed processing

This course will walk you through production-ready, repeatable techniques for addressing each of these challenges and many more.

What will you build?

This course focuses on creating a series of different projects of increasing complexity. You'll start from the very basics, understanding how to access ChatGPT 4 programatically.  From there, we will quickly increase in complexity, building more complex projects with many more features. By the end, you will make a fully-featured web app that implements a "Chat-with-a-PDF" feature. Note: no previous web development experience is required.

Here's a partial list of some of the topics you'll cover:

  • Understand how complex text-generation pipelines work
  • Write reusable code using chains provided by LangChain
  • Connect chains together in different ways to dramatically change your apps behavior with ease
  • Store, retrieve, and summarize chat messages using conversational memory
  • Implement semantic search for Retrieval-Augmented Generation using embeddings
  • Generate and store embeddings in vector databases like ChromaDB and Pinecone
  • Use retrievers to refine, reduce, and rank context documents, teaching ChatGPT new information
  • Create agents to automatically accomplish tasks for you using goals you define
  • Write tools and plugins to allow ChatGPT to access the outside world
  • Maintain a consistent focus on performance through distributed processing using Celery and Redis
  • Extend LangChain to implement server-to-browser text streaming
  • Improve ChatGPT's output quality through user-generated feedback mechanisms
  • Get visibility into how users interact with your text generation features by using tracing

There are a ton of courses that show how to use ChatGPT at a very basic level. This is one of the very few courses online that goes far beyond the basics to teach you advanced techniques that top companies are using today. I have a passion for teaching topics the right way - the way that you'll actually use technology in the real world. Sign up today and join me!
