What it does
This is a Chinese-language beginner's guide to LangChain, a programming toolkit for connecting AI language models to outside data and tools. It explains core ideas such as loaders, documents, text splitting, vector stores and chains.
It walks through example projects, such as answering questions about documents, summarizing content and searching the web with an AI model, with code you can run in Google Colab.
The author notes the guide was written some time ago and LangChain changes quickly, so some code may be out of date.
Who it's for
Chinese-speaking programmers who want to learn to build AI apps with LangChain.
