Project Title

Langchain-Chatchat — Open-Source, Offline-Capable RAG and Agent Application for Local Knowledge-Based LLMs

Overview

Langchain-Chatchat is an open-source project that provides a local knowledge-based question-answering application using large language models (LLMs) like ChatGLM, Qwen, and Llama, along with the Langchain framework. It aims to offer a solution friendly to Chinese scenarios and open-source models, supporting offline deployment. The project stands out for its comprehensive support for mainstream open-source LLMs, embedding models, and vector databases, enabling private, offline deployments.

Key Features

Comprehensive support for various mainstream LLMs, embedding models, and vector databases.
Offline, private deployment capabilities.
Integration with OpenAI GPT API and continuous expansion of model and API support.
Utilizes frameworks like Xinference and Ollama to接入 models such as GLM-4-Chat, Qwen2-Instruct, and Llama3.
Provides API services through FastAPI and a WebUI for operation using Streamlit.

Use Cases

Enterprises requiring a private, offline knowledge base问答 system.
Developers looking to leverage local knowledge for chatbot applications without reliance on cloud services.
Researchers and data scientists needing to experiment with various LLMs in an offline environment.

Advantages

Open-source and customizable, allowing for community contributions and improvements.
Supports a wide range of models and frameworks, offering flexibility in deployment.
Enables the creation of knowledge-based applications that can operate without internet connectivity.

Limitations / Considerations

The project does not include model training or fine-tuning processes, which may be necessary for certain applications.
While it supports a variety of models, the effectiveness can vary depending on the specific model used.

Langchain: The framework that Langchain-Chatchat is based on, providing a foundation for building applications with LLMs.
