ChatGPT: Systems, Workflows, and Prompt Engineering

You know how to use ChatGPT. Now learn how to make it work.Most people plateau a week after they start using ChatGPT. They get fluent at asking questions and never get good at building systems. They write the same prompt three times a day instead of once, ship the same kind of half-formatted output, and watch power users get five times the leverage out of the same model.This book closes that gap.ChatGPT: The Power User Guide is the advanced companion to ChatGPT: The Definitive Guide - written for professionals, developers, creators, and analysts who already know the basics and want to operate at a different level. Where the Definitive Guide teaches you to drive, this book teaches you to race.What's inside:Think in systems, not prompts. How the GPT-5 family actually works under the hood - tokens, context windows, auto-switching, system prompts, and the hidden prompt stack - so you stop guessing and start engineering.Master prompt architecture. The RISEN framework, structural prompt layering, negative prompting, delimiter strategies, chain-of-thought control, tree-of-thought, and verification chains.Build advanced workflows. Reusable prompt systems, Agent Mode strategies, Deep Research power techniques, data analysis at scale with Code Interpreter, production-grade content pipelines, and code/technical workflows.Design and ship Custom GPTs. Instructions, knowledge files, tool configuration, testing methodology, governance for teams, and analytics - including ready-to-adapt instruction templates.Integrate ChatGPT into your stack. Memory and personalization at depth, the MCP connector ecosystem, Notion/Obsidian/Excel/Zapier patterns, the Atlas browser, and when to graduate from chat to the API.50 power user prompt patterns organized by technique - each with the pattern, when to use it, an example, and why it works.If you're tired of using 10% of ChatGPT and watching power users do five times the work in half the time, this is the book that closes the gap.Includes coverage of GPT-5.3, GPT-5.4 Thinking, Agent Mode, Deep Research, Custom GPTs, MCP connectors, the ChatGPT API, and every 2026 power-user feature.
