Overview

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Unlock the power of AI by learning to build your own ChatGPT-powered application from scratch using Python and React. You'll gain hands-on experience integrating with the ChatGPT API, deploying backend services with FastAPI, and designing interactive front-end interfaces. By the end of the course, you’ll understand not just how to use AI, but how to create intelligent systems tailored to your needs. The course begins by grounding you in the basics—API registration, essential resources, and foundational Python usage with the ChatGPT API. As you progress, you’ll build API interaction skills and move into building and deploying your own backend using Python’s FastAPI framework. Next, you’ll shift gears to the front end, where you’ll create and style a React application that communicates with your ChatGPT backend. This prepares you for more advanced customization techniques like fine-tuning ChatGPT models for specific applications and choosing the right GPT variant for your use case. This course is ideal for Python developers, full-stack enthusiasts, and AI practitioners looking to level up. Prior experience in Python and React is recommended, and the course is best suited for learners at an intermediate level. By the end of the course, you will be able to register for and interact with the ChatGPT API, build a custom FastAPI-based backend, develop a connected React front-end, fine-tune models, and choose the best GPT variant for specific project goals.
