If you meant something else (e.g. the older Codex model or a specific setup), let me know!\n\n---\n\n## What is Codex?\n\n- Codex is a tool that helps with code tasks\u2014writing code, reviewing code, running tests, etc.\u2014all inside a sandboxed environment tied to your project. ([cdn.openai.com](https://cdn.openai.com/pdf/8df7697b-c1b2-4222-be00-1fd3298f351d/codex_system_card.pdf?utm_source=openai))  \n- It\u2019s included with ChatGPT Plus, Pro, Business, Enterprise, and Edu plans (and for a limited time with the Free/Go plan in many regions). ([help.openai.com](https://help.openai.com/en/articles/11369540-using-codex-with-your-chatgpt-plan%28.pdf?utm_source=openai))  \n\n---\n\n## How to Install Codex\n\nThere are a few ways to install, depending on whether you want a desktop app, a command-line version, or use it within an IDE.\n\n---\n\n### 1. Desktop App (macOS / Windows)\n\n- Download the desktop Codex app from OpenAI\u2019s website (for macOS or Windows). ([farstarhq.com](https://farstarhq.com/docs/en/guides/codex?utm_source=openai))  \n- Install it like other applications.  \n- Open it, then sign in with your **ChatGPT account** or (in some cases) with an **API key.** ([farstarhq.com](https://farstarhq.com/docs/en/guides/codex?utm_source=openai))  \n\n---\n\n### 2. Command-Line Interface (CLI)\n\nIf you prefer using Codex in your terminal:\n\n#### On macOS / Linux:\n\n```bash\ncurl -fsSL https://chatgpt.com/codex/install.sh | sh\n```\n\nYou can also use:\n\n```bash\nnpm install -g @openai/codex\n```\n\nOr, if you're on macOS:\n\n```bash\nbrew install --cask codex\n```\n\n([github.com](https://github.com/openai/codex/blob/main/README.md?utm_source=openai))\n\n#### On Windows:\n\nOpen PowerShell and run:\n\n```powershell\nirm https://chatgpt.com/codex/install.ps1 | iex\n```\n\n([github.com](https://github.com/openai/codex/blob/main/README.md?utm_source=openai))\n\n---\n\n## Setup After Install\n\n1. **Sign in**: Use your ChatGPT account (the same one that has your subscription) or an API key if that\u2019s supported. ([help.openai.com](https://help.openai.com/en/articles/11369540-using-codex-with-your-chatgpt-plan%28.pdf?utm_source=openai))  \n2. **Launch**: In terminal, type `codex` to open the interface. Alternatively, open the desktop app.  \n3. **Choose a mode** (for the CLI):\n\n   - `\u2014suggest` (default): suggests edits, doesn\u2019t change anything without your approval  \n   - `\u2014auto-edit`: edits automatically but asks before running commands  \n   - `\u2014full-auto`: runs commands automatically in a sandboxed, secure environment ([help.openai.com](https://help.openai.com/en/articles/11096431?utm_source=openai))  \n\n4. **Grant permissions** if asked, especially file read/write access. These are required for Codex to inspect your project folder. You control exactly what it can do. ([reddit.com](https://www.reddit.com/r/ChatGPT/comments/1snb06d/beginner_guide_for_anyone_on_chatgpt_who_has/?utm_source=openai))  \n\n---\n\n## Keeping it Updated\n\nDepending on how you installed it:\n\n- If via npm: `npm install -g @openai/codex@latest` ([farstarhq.com](https://farstarhq.com/docs/en/guides/codex?utm_source=openai))  \n- If via Homebrew: `brew upgrade --cask codex` ([farstarhq.com](https://farstarhq.com/docs/en/guides/codex?utm_source=openai))  \n- If via install script: re-run the install script to get the latest version. ([github.com](https://github.com/openai/codex/blob/main/README.md?utm_source=openai))  \n\n---\n\nIf you tell me your OS (macOS, Windows, Linux) or whether you prefer GUI or CLI, I can give you a super-tailored command sequence. Do you want that?"
