Building a Retrieval Augmented Generation System Using FastAPI

August 20, 2024

Course Category: Generative AI

Course Description

Large Language Models (LLMs) are compressions of human knowledge found on the internet, making them fantastic tools for knowledge retrieval tasks. However, LLMs are prone to hallucinations—producing false information contrary to the user's intent and presenting it as if it were true. Reducing these hallucinations is a significant challenge in Natural Language Processing (NLP).

One effective solution is Retrieval Augmented Generation (RAG), which involves using a knowledge base to ground the LLM's response and reduce hallucinations. RAG enables LLMs to interact with your documents, the content of your website, or even YouTube video content, providing accurate and contextually relevant information.

Throughout this project, you'll acquire a diverse set of skills crucial in modern technology and software development fields. These include:

  • API Design and Management: Learn to design and manage APIs efficiently.
  • Data Handling and Parsing: Master robust techniques for handling and parsing data across various document formats.
  • Database Design and Management: Gain proficiency in structuring and manipulating data in databases.
  • AI Model Integration: Seamlessly incorporate advanced AI functionalities into your applications.

By the end of this project, you will be able to build a complete RAG system from scratch using FastAPI and OpenAI’s API. The only prerequisites for this project are some experience with Python and a basic understanding of web development.
