What's This Course About

Master OpenAI Codex end to end in this hands-on 1-day Codex Masterclass. Codex is OpenAI’s agentic coding assistant that plans, writes, runs and fixes code on its own—in your terminal, in your IDE and in the cloud. Instead of coding every step yourself, you will describe goals in plain language and let Codex act as an autonomous pair programmer while you review and guide the work.

Through practical projects, participants will set up the Codex CLI, delegate multi-step coding tasks to the agent, connect tools, repositories and data sources, and build and automate a working application end to end. You will also learn to review, test and guardrail AI-generated code so your agent stays reliable and safe. By the end of the masterclass, you will be able to build and ship software faster with a complete Codex-powered agentic workflow.
