About
About this course
OpenAI Codex is the agentic coding model that turns plain-English instructions into working code, tests and shipped features. This course walks you through Codex as an agentic developer, from your first task to autonomous multi-file changes, so you can build real projects with AI doing the heavy lifting. It is built for non-developers ready to ship software and for engineers who want a serious productivity jump. By the end you will confidently direct Codex across real repos and ship working apps you can put in front of users.
