A few weeks ago, OpenAI announced that Codex is available for Plus users, and I didn\u2019t miss a chance to try it. And today, I\u2019m excited to share a guide to OpenAI\u2019s Codex. As a developer, I\u2019ve found it to be a powerful and practical tool.<\/p>\n

What is OpenAI Codex?<\/h2>\n

OpenAI Codex is an AI model that turns your plain English instructions into code. It supports dozens of programming languages (including Python, JavaScript, Go, Ruby, and more) and is powerful enough to understand and generate code in those languages. In essence, if you describe a programming task or ask a question about code, Codex will try to produce a helpful answer in the form of code or an explanation.<\/p>\n

<\/figure>\n

It\u2019s built upon the GPT (Generative Pre-trained Transformer) family of models, specifically trained on a massive dataset of publicly available source code from GitHub and natural language text.<\/p>\n

However, don\u2019t confuse, Codex is not an extension for your IDE, it\u2019s a cloud-based software engineering agent that can work on multiple tasks in parallel. You connect it to your GitHub repository, give it tasks in plain English, and it goes to work. That simple! \ud83d\ude42<\/p>\n

It can:<\/strong><\/p>\n

    \n
  1. \n

    Read and understand your existing codebase.<\/p>\n<\/li>\n

  2. \n

    Write new code across multiple files: Not just snippets, but actual features or fixes.<\/p>\n<\/li>\n

  3. \n

    Run tests (if you guide it or have them set up).<\/p>\n<\/li>\n

  4. \n

    Debug issues.<\/p>\n<\/li>\n

  5. \n

    Explain parts of your code.<\/p>\n<\/li>\n

  6. \n

    Propose and even draft Pull Requests directly to your GitHub repo!<\/p>\n<\/li>\n

  7. \n

    And more<\/p>\n<\/li>\n<\/ol>\n

    Getting Started with Codex<\/h2>\n

    Alright, theory is nice, but let\u2019s get practical. To try Codex, you will need at least a Plus subscription for ChatGPT and a\u00a0GitHub account<\/a>.<\/p>\n

    Simply open\u00a0https:\/\/chatgpt.com\/codex<\/a>\u00a0and log in to your account.<\/p>\n

    Connecting your GitHub account<\/h3>\n

    The first big step is connecting your GitHub account<\/strong>. Once you click the \u201cConnect to GitHub\u201d button, you\u2019ll be redirected to GitHub to authorize OpenAI.<\/p>\n

    GitHub will ask you what repositories you want to grant Codex access to.\u00a0You can choose:<\/strong><\/p>\n
