In this short course, we take you on a fun, hands-on and pragmatic journey to learn how to build LLM powered apps using LangChain. You'll start building your first Generative AI app within minutes. Every section is recorded in a bite-sized manner and straight to the point as I don’t want to waste your time (and most certainly mine) on the content you don't need.
In this course, we will cover:
What is LangChain
How does LangChain Work
Installation, Setup and Our First LangChain App
Building a Medium Article Generator App
Connecting to OpenAI LLM
Prompt Templates
Simple Chains
Sequential Chains
Agents
Chat with a Document
Adding Memory (Chat History)
Outputting the Chat History
Uploading Custom Documents
Loading Different Document Types (eg PDF, txt, docs)
Chat with Youtube and more...
The goal of this course is to teach you LangChain development in a manageable way without overwhelming you. We focus only on the essentials and cover the material in a hands-on practice manner for you to code along.
Working Through This Course
This course is purposely broken down into short sections where the development process of each section will center on different essential topics. The course a practical hands on approach to learning through practice. You learn best when you code along with the examples.

Great course. Gives a quick and practical overview how to use langchain but also, how to use the novel UI framework streamlit.
I would very recommend everyone this course if you want do discover the langchain framework!

Really enjoyed this practical introduction to LangChain! Straight to the point and building two example projects helped me see what LangChain is capable of.

I like the clarity of how the author brings us through a step-by-step process of using the libraries from LangChain to achieve the goal as described in each section. Very straightforward.
One thing that I would like to see is how the author gets the import statements for the various libraries. Knowing how to get the dependencies is an equally important skill for the modern developer.

This is a great introductory course on LangChain. I appreciate the instructor's direct and concise way of presenting the material, from giving a thorough summary of how the LangChain works, to walking through the configuration and providing a practical project that I can build on. Videos are great quality, very clear. Greg gives you a good foundation to take what you've learned and expand on it. I feel confident I can build on the article generator, and understand how to integrate it with other open source LLMs. Another great course from Greg!

Really enjoyed this course! It's a great way to get introduced to using Langchain and I particularly enjoyed the inclusion of realistic projects at the end. You get the knowledge of both how to use the library and the knowledge of how to apply it practically.

Greg does great work in talking through the complexity of Langchain. Watching over his shoulder as he walks through the python code is very helpful to understand exactly what to do in langchain.

Like all of Greg's courses and books, the coding process is easy to follow. The subject of this course is current, interesting and own project encouraging.

LangChain for Beginners is a stellar course that will help you master the core concepts of this amazing open-source framework in no time. The course is well-organized, hands-on, and straightforward, making it easy to follow along. As you know, Greg Lim does not disappoint, even his recent Next.js 13 and React Crash Course 2023 was Wow I used to learn Next JS (I had an idea about React js though) and this course He continues to do an excellent job of explaining the material and demonstrating how to use LangChain in practical projects as all his other courses. By the end of the course, you'll have a solid understanding of LangChain and the skills to build powerful NLP applications. So, if you're looking for a comprehensive and practical introduction to LangChain, this course is highly recommended.

Good course to start, the author obviously knows how to focus on the most important things within limited time span.

This was a really good exercise/course for me to code along, and improve my Python coding skills. I felt section 1 was explained better than section 2 - as I personally found some bugs. However, overall a very good course to get you up and running (rather than procrastinating as I was doing)

The course is a super quick practical introduction to using langchain to build apps. It covers a lot of ground necessary as a beginner. After finishing this course, you can follow it up with all the latest open source models being released and test them with the apps presented here.

Nice pace and clear explanations, easy to follow. The choice of solutions built tickled my interest immediately and I do not want to stop learning!

This article / this course is breaking down what i assumed was a mountain of complexity , into understandable "chunks". It is my opening adventure exploring langchain and as soon as I complete this course, i am going to continue since langchain is not as mysterious as it was, thanks to Mr. Lim. To continue, now that I have finished the course, the instructor walks us through the usage of this tool, to the point of explaining the steps, and then actually doing the step, that is using the tool , and demonstrating error handling, what to do , how to avoid them, and then how to get around them. This course is very important for those people who want / need to dive into this very intriguing line of study.

great course . this tech is new to me and it was wonderful to understand how to build an actual app with this. Great job by the instructor

In this course, the instructor takes us on an awesome guided tutorial on how to build a few apps using Langchain, OpenAi, & Python.
There were great concepts here like new Python pips to help with creating llm chatbots. Previous to this course I had no idea how to approach building LLM bots. I was struggling to find a 'practical' coding guide for an indie coder such as myself.
I like the teaching style of Greg Lim, he wants you to excel and learn by doing, and I'm super comfortable with that. I'm going to see what other material he has to offer.
An awesome takeaway is being able to deploy an app with the newly absorbed information relatively promptly lol..
Thank You!
