# Codex Unlocked

The AI That Comes Free With ChatGPT, and How to Put It to Work Without Writing Code

## About the book

Codex is the part of your ChatGPT subscription almost nobody opens, even though it is already paid for. This book walks through everything Codex can do for you in plain language: describing tasks instead of coding, Goal Mode, memory and the models, explained so they make sense. Written for normal people, not developers, and honest about where the limits are. Current to July 2026.

## What is inside

17 chapters in plain language: what Codex is and why it is inside your ChatGPT subscription, describing tasks instead of writing code, Goal Mode, memory and the models, and how it becomes an assistant that does real work.
