The RAG Playground web application provides a web interface to the RAG query server.
By selecting Demo, you can chat with the LLM and see responses streamed back for different examples.
By selecting Use Knowledge Base, the chatbot returns responses that are augmented with data from documents that you uploaded and were stored in the vector database.
To store content in the vector database, click the Knowledge Base tab.
