ChatGPTWriting code by hand can feel slow, repetitive, and cluttered, especially when every small change demands careful setup and manual checks. Codex is OpenAI’s AI system trained to understand and generate code, and it helps developers work faster by handling routine tasks, spotting patterns, and producing clean updates with far less effort. Instead of juggling tools and worrying about small mistakes, you can rely on Codex to manage the heavy lifting so you focus on what you actually want to build.
With OpenAI Codex, you can push real changes to a GitHub repo without touching your keyboard. This tutorial will show you exactly how. You will use OpenAI Codex to connect a repository, set up a live execution environment, plan a modification, let the agent implement the update, check the output, and open a pull request. By the end, you will have shipped your first change entirely through an AI-driven workflow inside your browser.
By the end of this tutorial, you'll be able to:
- Access OpenAI Codex
- Set up the environment and repository
- Choose either planning or code execution
- Use Codex to make changes to your codebase
Let’s dive into the details to find out how Codex can make your life easy.
