Building a Retrieval-Augmented Generation System Using FastAPI

PROJECT


Building a Retrieval-Augmented Generation System Using FastAPI

In this project, we will learn how to build a Retrieval-Augmented Generation (RAG) system using FastAPI and OpenAI’s API. This system will let users upload documents and chat about the content.

Building a Retrieval-Augmented Generation System Using FastAPI

You will learn to:

Harness the semantic search in AI applications.

Build and optimize a RAG system using OpenAI’s GPT models.

Create text embeddings with the appropriate chunking strategy.

Design and manage a database using PostgreSQL.

Design and manage APIs with FastAPI.

Parse textual data and the PDF data using OCR.

Project Description

Throughout this project, we will acquire a diverse set of skills that are crucial in modern technology and software development fields. These include understanding and implementing API design and management concepts, ensuring robust data handling, and parsing techniques for various document formats. Users will gain proficiency in database design and management, learning to structure and manipulate data efficiently. The project also emphasizes skills in AI model integration, teaching users to seamlessly incorporate advanced AI functionalities into applications.

After completing this project, the learner can build an RAG system from scratch using FastAPI and OpenAI’s API. The only requirements for this project are some experience with Python and a basic understanding of web development.
