Decision brief

Langchain-Chatchat is a local knowledge-based application that integrates RAG and Agent functionalities using Langchain and various language models like ChatGLM, Qwen, and Llama.

Good fit when

  • When you need a local deployment of a knowledge-based application that supports multiple language models including ChatGLM, Qwen, and Llama.
  • If you require an application that leverages Langchain for RAG and Agent functionalities, and you prefer a setup that can be easily managed through Docker.

Avoid when

  • If you are looking for a cloud-based solution that does not require local deployment and management.
  • When your project specifically requires a different set of language models that are not supported by Langchain-Chatchat, such as models that are not listed in its documentation.
