OpenAI Codex Tutorial for Beginners: CLI, App, and Workflows

The short answer

OpenAI Codex is OpenAI's AI coding agent. It can work on your codebase from the terminal, in editors, or as cloud tasks, writing and testing code from natural-language instructions. Like any coding agent, it works best with a clear task, small scoped changes, and a way to verify the result.

Builders increasingly run more than one agent: Codex for some tasks, Claude Code for others, each checked against tests. The posts and videos below track what's changing in Codex and how we fit it into real builds.
