But you *can* install the client tools and apps that let you use Codex with your ChatGPT account. ([openai.com](https://openai.com/index/codex-now-generally-available/?utm_source=openai))\n\nHere are the options:\n\n| Method | What you download / install | Where |\n|--------|-----------------------------|-------|\n| **Codex CLI** | Install a terminal app that interfaces with the Codex model. It works locally but connects to OpenAI in the backend. ([help.openai.com](https://help.openai.com/en/articles/11096431?utm_source=openai)) | `npm i -g @openai/codex`, or grab binaries from GitHub Releases or releases.openai.com. ([github.com](https://github.com/openai/codex?branch=main&utm_source=openai)) |\n| **Codex App (desktop)** | A GUI app (\u201ccommand center\u201d) for managing agents, workflows, etc. Runs on macOS (already released), Windows support added later. ([openai.com](https://openai.com/index/introducing-the-codex-app/?utm_source=openai)) | Download from the OpenAI website under Codex section, or via official app links. ([openai.com](https://openai.com/index/introducing-the-codex-app/?utm_source=openai)) |\n| **IDE extension** | Plugins/extensions for editors like VS Code, which embed Codex features. ([help.openai.com](https://help.openai.com/en/articles/11369540/?utm_source=openai)) | Installed from the IDE store or from OpenAI\u2019s Codex documentation / GitHub. |\n\nTo use these, you\u2019ll likely need a ChatGPT account. Codex is included in several subscription plans (Plus, Pro, Business, Enterprise, Edu), and for a time even the Free/Go plans had access. ([help.openai.com](https://help.openai.com/en/articles/11369540/?utm_source=openai))\n\n---\n\n### \u26a0\ufe0f If you meant \u201cCodex\u201d as in the old GPT-3-based code generation model (e.g. \u201cCodex\u201d from 2021)\n\nThat older version, fine-tuned on code by OpenAI, is *not* available for download. It\u2019s only accessible through the OpenAI API. The trained model files haven\u2019t been released publicly. If you\u2019re fine with calling it via API rather than downloading your own copy, you can get access that way. ([en.wikipedia.org](https://en.wikipedia.org/wiki/OpenAI_Codex?utm_source=openai))\n\n---\n\nIf you tell me *which* \u201cCodex\u201d you meant, and what you want to do with it (use locally, run servers, etc.), I can give more specific instructions."

Here's what I found on how to run it locally or with local elements:\n\n---\n\n## \ud83d\udce6 What \u201cCodex\u201d Offers\n\nOpenAI\u2019s modern Codex is a **coding agent** that operates in different modes \u2014 some parts cloud, others local \u2014 plus tools to help you use it in your dev flow. ([realpython.com](https://realpython.com/ref/ai-coding-tools/codex/?utm_source=openai))\n\nKey components:\n\n- **Codex CLI** \u2014 a terminal-based tool (\u201cagent\u201d) you run on your own computer. Works locally in a sandbox, interacts with your codebase, runs tests, etc. ([codex.danielvaughan.com](https://codex.danielvaughan.com/2026/03/27/codex-cloud-vs-local-when-to-run-in-cloud/?utm_source=openai))  \n- **Codex App** (desktop) \u2014 Mac (and soon Windows) app where you can manage agent threads, review diffs, use \u201cskills\u201d, etc. ([openai.com](https://openai.com/index/introducing-the-codex-app/?utm_source=openai))  \n- **IDE Extensions** \u2014 VS Code, JetBrains, etc., so Codex feels integrated into your editor. ([realpython.com](https://realpython.com/ref/ai-coding-tools/codex/?utm_source=openai))  \n- **Remote & Cloud Operations** \u2014 runs tasks in cloud sandboxes, handles jobs, approvals, etc. ([openai.com](https://openai.com/index/work-with-codex-from-anywhere/?utm_source=openai))\n\n---\n\n## \ud83d\ude80 How to Run Locally / Try \u201cVibe Coding\u201d\n\nIf you want an experience where you guide the AI (vibe coding), reviewing, prompting, refining, etc., locally \u2014 here's how to set that up.\n\n### 1. Install Codex CLI\n\nThis is the core local piece. It runs on your machine.\n\n- On **macOS/Linux**:  \n  ```bash\n  curl -fsSL https://chatgpt.com/codex/install.sh | sh\n  ```\n- On **Windows**:  \n  ```powershell\n  powershell -ExecutionPolicy ByPass -c \"irm https://chatgpt.com/codex/install.ps1 | iex\"\n  ```\n- Or via package managers:\n  - `npm install -g @openai/codex`\n  - `brew install --cask codex`  \n  ([github.com](https://github.com/openai/codex/blob/main/README.md?utm_source=openai))\n\nAfter installing, you run `codex` in your terminal. It will let you sign in via ChatGPT and select a project folder/repo. Then you can prompt it with tasks, open changes, approve diffs, etc. ([chatgpt.com](https://chatgpt.com/codex/get-started/?utm_source=openai))\n\n### 2. Use the Desktop App (macOS \u2192 Windows coming)\n\nIf you're on macOS, you can use the Codex App \u2014 it's got a more graphical UX: agent threads, local diffs, skills, git worktrees, etc. Windows support is \u201ccoming soon.\u201d ([openai.com](https://openai.com/index/introducing-the-codex-app/?utm_source=openai))\n\n### 3. Use IDE Extensions\n\nThere are extensions for editors like VS Code, etc., letting you invoke Codex from inside the editor so the workflow is smooth. ([realpython.com](https://realpython.com/ref/ai-coding-tools/codex/?utm_source=openai))\n\n### 4. How \u201cLocal\u201d is Local?\n\n- With **Codex CLI**: It runs tasks locally in sandboxed processes. It reads your local file system (limited to your project directory), runs tests locally, etc. ([codex.danielvaughan.com](https://codex.danielvaughan.com/2026/03/27/codex-cloud-vs-local-when-to-run-in-cloud/?utm_source=openai))  \n- With the **desktop app**: It interacts with your local files; you see and approve diffs, etc. ([openai.com](https://openai.com/index/introducing-the-codex-app/?utm_source=openai))  \n\n---\n\n## \u26a0\ufe0f What Isn\u2019t Included / Limitations\n\n- You *can\u2019t* download the actual model weights (like codex-1 or whatever version) to run fully offline. The heavy lifting tends to happen either in local sandboxed processes or cloud containers. ([cdn.openai.com](https://cdn.openai.com/pdf/8df7697b-c1b2-4222-be00-1fd3298f351d/codex_system_card.pdf?utm_source=openai))  \n- Some features still cloud-based (e.g. certain agents, workflows, if you want features that go beyond your local machine\u2019s hardware). ([codex.danielvaughan.com](https://codex.danielvaughan.com/2026/03/27/codex-cloud-vs-local-when-to-run-in-cloud/?utm_source=openai))\n\n---\n\nIf you tell me which OS you're using (macOS, Windows, Linux), I can send you exact download links/instructions to set it up. Do you want that?"
