Detailed Introduction

Langchain-Chatchat is an open-source project designed to provide a robust, offline-deployable solution for knowledge base question-answering using large language models (LLMs) and the Langchain framework. It addresses the need for private and secure RAG (Retrieval Augmented Generation) and Agent applications, especially for Chinese contexts and open-source models. The project supports a wide array of mainstream LLMs and embedding models, enabling users to build powerful AI applications without relying on external cloud services. It offers flexible interaction through both a FastAPI-powered API and a user-friendly Streamlit WebUI, making it accessible for developers and end-users alike.
