This lecture feels like having a mentor right next to you teaching you. I think the advantage is that the conversational teaching style makes it more comfortable to learn, and since I prefer this kind of interactive lecture format, it was very good for me. Also, it teaches the essential points needed for immediate implementation, so it's a great lecture for someone who needs to do something with langchain right now.

I've always wondered if Langchain is really necessary, but this lecture made me realize that it definitely improves the interface through features like organizing into JSON structures and chaining Runners. The easy explanations also motivated me to study further. Thank you so much for providing such an excellent lecture at an affordable price!!

How can a lecture like this be offered for just a few dollars? I wanted to create an LLM agent but felt lost because I knew absolutely nothing about LLMs, but this was a great help. Now I'm off to take the LangGraph lecture. Thank you!

LangChain Fundamentals in One Hour

Does LangChain feel vague and overwhelming? We'll cover just the essentials in one hour

  • When you try to read the official documentation, there are just countless tutorial notebooks

  • And even worse, it's all only in English

  • But once you know the basics, everything else is just application, so you don't need to follow every single tutorial

  • So I'll cover just the core fundamental concepts

Here's what you'll learn

Ollama

Are they telling you not to use GPT for security reasons while asking you to build something with LLM? We'll show you how to run local models using Ollama

Writing Prompts the LangChain Way

When writing prompts, you need to write them "in a LangChain way" to develop with a scalable structure. I'll show you how to use LangChain's PromptTemplate and ChatPromptTemplate

Generating responses in the desired format

Do you only need a single word, but the LLM provides too much additional explanation? Are you having trouble converting and delivering responses in JSON format? We'll show you how to modify LLM-generated responses to suit your needs

Connecting with LCEL Syntax

Do you want to handle complex tasks smoothly? I'll show you how to develop using LangChain syntax in a readable and scalable way by utilizing LCEL syntax across multiple steps

Prerequisites

Practice Environment

  • The course was recorded in a MacOS environment, but it is also compatible with Windows and Linux as long as Python is installed.

  • The course uses the Cursor editor, but you can use any editor such as VSCode, Jupyter Notebook, PyCharm, etc.

Learning Materials

  • GitHub Source Code

  • Please refer to the code comments as there are no separate explanation materials such as Notion or Gitbook

Prerequisites and Important Notes

  • Python required!

          Even though this was my first time encountering this part, I was able to grasp the overall flow in a short time, which was great. Thank you.
