We have deployed a Vector database which hosts the knowledge base embeddings. Knowledge base pdf files are stored in a file server, and the Data science pipeline discovers new files based on the schedule and ingests the embeddings into the Vector database. LangChain integrates components such as Gradio UI framework, Llama 2 model which is served by vLLM serving runtime and Vector database.
All necessary components required for digital assistant to function are deployed and Digital assistant UI can be accessed by going to the route section under digital assistant namespace, where you will find the link.
