Most people are still only scratching the surface of what tools like ChatGPT can do.
They type something in, get a response back, tweak a few words, and hope it improves. Sometimes it does. Sometimes it doesn't. What is usually missing is a deeper understanding of how large language models work and why prompt engineering makes such a difference.
This fully rebuilt and expanded 2026 edition of The Art of Prompt Engineering with ChatGPT was created to fix that.
Written in clear, accessible language, this book helps you develop practical prompt engineering skill that goes far beyond one model, one platform, or one moment in time. Whether you use ChatGPT, Claude, Gemini, Copilot, DeepSeek, or the tools that come next, the ideas in this book are designed to help you understand the deeper mechanics behind them and use that understanding well.
Inside, you will find:
