Overview

About this course.

Codex Fast Track is an intensive two-day course that equips participants with practical skills to use ChatGPT Codex effectively in their work. This zero-to-hero training covers both the mechanics of the tool and the disciplines that make it reliable. Participants work hands-on with Codex to learn how to ground prompts in real project context, plan before generating, verify outputs, and build repeatable workflows. The curriculum progresses from foundational concepts (opening projects, managing context, creating AGENTS.md guidance) through advanced capabilities (complex workflows, context management, and orchestrated task sequences). Throughout the course, you'll work within a hands-on scenario that provides realistic context for practicing Codex at scale. By completion, you will understand when and how to use Codex effectively, how to catch and fix unreliable outputs, and how to build project-level rules that keep Codex consistent. Students are responsible for ensuring all required accounts, software, licenses, and online resources are accessible and functioning prior to class. See the prerequisites section for more details.
