Developing Apps with GPT-4 and ChatGPT: Build Intelligent Chatbots, Content Generators, and More

The Challenge It Addresses

Building applications powered by large language models (LLMs) like GPT-4 and ChatGPT presents a steep learning curve for even experienced developers. The complexity of API integration, prompt engineering, managing context windows, and handling cost and latency can stall projects before they launch. This book removes that friction by providing a concise, hands-on guide specifically for Python developers who want to go from zero to a production-ready LLM application.

Rather than wading through scattered documentation, this minibook delivers a focused, practical path to building intelligent chatbots, content generators, and more.

What Is Developing Apps with GPT-4 and ChatGPT: Build Intelligent Chatbots, Content Generators, and More? A Complete Overview

Developing Apps with GPT-4 and ChatGPT (First Edition, 2023) by Olivier Caelen and Marie-Alice Blete is a comprehensive minibook published by O’Reilly Media. It serves as a complete guide for Python developers aiming to harness the capabilities of OpenAI’s powerful models.

The book covers the entire development lifecycle, from setting up your environment and understanding the OpenAI API to advanced techniques like fine-tuning, managing context, and deploying cost-effective solutions. It bridges the gap between theory and practical application with actionable code examples.
