Project
Langchain-Chatchat
Langchain-Chatchat is a Chinese-community RAG and agent application framework that began as Langchain-ChatGLM in 2023.
Overview
The project provides a historical example of self-hosted knowledge-base question answering using ChatGLM, Qwen, Llama and LangChain. Its official roadmap describes the 2023 and 2024 releases. Repository activity has been limited since November 2025; current compatibility with newer models and dependencies must be checked before deployment.
Origin & context
The project began in the Chinese-language Langchain-ChatGLM developer community and later became Langchain-Chatchat. Its first-party README records participation in a Chinese AI hackathon organized by Founder Park, Zhipu AI and Zilliz. This establishes a China-linked developer-community origin, not ownership by those hackathon organizers.
