Creating a Powerful Chatbot: rag GPT for Rag

In this video tutorial, you will learn how to design and develop a chatbot called rag GPT, which specializes in rag retrieval augmented generation. The chatbot offers multiple functionalities, with rag being the primary focus.

Four Essential Libraries for Chatbot Design

To build the rag GPT chatbot, you will utilize four key libraries:

  1. Gradio: This library helps in designing the user interface for the chatbot.
  2. OpenAI's Embedding Model: Used to enhance the language model capabilities of the chatbot.
  3. GPT 3.5: A powerful language model that enables the chatbot to generate responses.
  4. Lang Chain and Chroma: These libraries play a crucial role in designing the rag side of the chatbot.

Functionality of the Chatbot

The rag GPT chatbot offers three main functionalities:

  1. Connect with a Vector Database: The chatbot can interact with a vector database, allowing for effective question-and-answer sessions with documents.
  2. Upload Documents: Users can upload a document and engage in a conversation with the chatbot based on its content.
  3. Document Summarization: The chatbot can summarize lengthy documents, providing a concise overview regardless of the document's length.

Live Demonstration

The video tutorial showcases the chatbot's capabilities by demonstrating its usage with three different documents:

  1. A paper on the clip model
  2. A paper on vision Transformer
  3. A lecture by Sam Alman about startups

The chatbot successfully retrieves relevant content based on the questions asked and provides accurate answers. Additionally, it can search and extract information from uploaded documents and generate concise summaries, even for lengthy 15-page papers.
