LangChain Basics in One Hour

LangChain, do you feel vague? We will finish the core in one hour.

  • If you want to read the official documentation first, there are only tutorial notebooks.

  • And even then, it's all in English

  • However, if you know the basics, the rest is application, so you don't need to follow all the tutorials.

  • So I'll just touch on the core, basic concepts.

Learn about these things

Ollama

Why are you telling me not to use GPT for security reasons and what should I create with LLM? I will show you how to run a local model using Ollama.

Writing a Langchain-like prompt

When writing prompts, you need to write them "Langchain-like" to develop an expandable structure. I will show you how to use Langchain's PromptTemplate and ChatPromptTemplate.

Generate answers in the format you want

I only need one word, but LLM is giving me too many explanations? Are you having trouble converting it to JSON and sending it? Here's how to customize the answers LLM generates to your taste.

Connection using LCEL grammar

Do you want to handle complex tasks smoothly? I will teach you how to develop multiple steps using LCEL grammar, with high readability and extensibility using Langchain grammar.

Things to note before taking the class

Practice environment

  • The lecture was filmed in a MacOS environment, but it can also be used on Windows and Linux if Python is installed.
