Codex AI Series

Codex is OpenAI's coding agent, built to work alongside developers on real engineering tasks — reading an existing codebase, writing and refactoring code, running tests and iterating on the result. Used well, it shifts a developer's time away from boilerplate and towards design, review and judgement, and it is quickly becoming a standard part of the professional toolchain rather than a novelty.

The Codex AI Series teaches that workflow in practice. You will learn to drive Codex effectively — scoping a task, giving it the right context, reviewing and correcting what it produces, and keeping quality and security standards intact while working at speed. The series runs from AI vibe coding with Codex for those getting started, through to a Codex masterclass for developers who want to apply it confidently across day-to-day engineering work.
