Earlier than You Set up<\/h2>\n

Use the standalone installer if you don’t already handle developer instruments by means of Homebrew or npm.<\/p>\n

Home windows: PowerShell on a supported Home windows system. WSL2 is non-compulsory.<\/p>\n

Home windows PowerShell<\/h4>\n

powershell -ExecutionPolicy ByPass -c “irm https:\/\/chatgpt.com\/codex\/set up.ps1 | iex”<\/p>\n

You can even run this by way of CMD. It executes the PowerShell command.<\/p>\n

\n
\"Windows<\/figure>\n<\/div>\n

The Home windows installer provides Codex to your PATH; consequently, it’s prepared to be used. It additionally presents to launch the applying.<\/p>\n

Word: If the installer asks to begin Codex instantly, press N. Do that except the terminal is already inside a undertaking folder.<\/p>\n

Various set up strategies<\/h4>\n

Do you favor a bundle supervisor? Use certainly one of these choices as an alternative:<\/p>\n

# Homebrew
\nbrew set up –cask codex<\/p>\n

# npm
\nnpm set up -g @openai\/codex<\/p>\n

Equally, Homebrew is appropriate for a Brew-managed Mac setup. Use npm if Node.js already manages your international developer instruments.<\/p>\n

First Run<\/h2>\n

2. Open a undertaking folder<\/h3>\n

Transfer into the repository the place you need Codex to work. Then, launch it.<\/p>\n

# Home windows PowerShell
\ncd C:Usersyoucodemy-project
\ncodex<\/p>\n

# macOS or Linux
\ncd ~\/code\/my-project
\ncodex<\/p>\n

Codex treats the present listing as its beginning workspace. By default the System32 listing can be the default one. <\/p>\n

3. Select sign up<\/h3>\n

The primary launch presents three sign-in routes:<\/p>\n

Register with ChatGPT: Makes use of the Codex allowance out of your ChatGPT plan.<\/p>\n

Register with Gadget Code: Greatest for SSH, containers, or machines with out a browser callback.<\/p>\n

Present your personal API key: Utilization is billed by means of the OpenAI Platform account linked to that key.<\/p>\n

\n
\"Codex<\/figure>\n<\/div>\n

OpenAI\u2019s present Codex pricing web page lists Free, Go, Plus, Professional, Enterprise, Edu, and Enterprise plans. API-key utilization is billed individually. However, utilization in a subscription is shared between the online app and Codex.<\/p>\n

4. Authorize Codex within the browser<\/h3>\n

In case you select ChatGPT, Codex prints an authentication URL. It additionally opens this URL in your browser. If the browser doesn’t open, copy and paste the URL your self.<\/p>\n

\n
\"PowerShell
Codex prints the browser sign-in URL within the terminal.<\/figcaption><\/figure>\n<\/div>\n

Subsequent, sign up to the browser utilizing the ChatGPT account you need Codex to make use of.<\/p>\n

\n
\"ChatGPT<\/figure>\n<\/div>\n

Verify the account on the affirmation display screen earlier than you proceed.<\/p>\n

\n
\"ChatGPT<\/figure>\n<\/div>\n

Consequently, when the browser reveals the success web page, shut the tab. Then, return to the terminal.<\/p>\n

\n
\"Browser<\/figure>\n<\/div>\n

5. Evaluate the first-run discover<\/h3>\n

Again within the terminal, Codex confirms your account. It additionally reminds you that autonomy is a selection. Don’t ignore this discover. Press Enter after you learn it.<\/p>\n

\n
\"Codex
Codex confirms the ChatGPT login and asks you to overview its autonomy settings<\/figcaption><\/figure>\n<\/div>\n

You’ll be able to examine or change the energetic boundary later. Use the \/permissions command to do that.<\/p>\n

6. Belief the suitable folder<\/h3>\n

Codex now prints the listing it’s about to belief. Learn the trail fastidiously. Don’t simply take a look at the highlighted possibility.<\/p>\n

\n
\"Directory
Don\u2019t use System32 as default listing (it is a VM for demonstration)<\/figcaption><\/figure>\n<\/div>\n

Belief permits project-local configuration, hooks, and execution insurance policies to load. If the trail is fallacious, give up this system. Transfer into the right repository and run codex once more.<\/p>\n

7. Configure the Home windows sandbox<\/h3>\n

On native Home windows, Codex could ask create its sandbox. Select the default sandbox in the event you can approve the administrator immediate.<\/p>\n

\n
\"Codex
The default Home windows sandbox is the popular possibility<\/figcaption><\/figure>\n<\/div>\n

OpenAI\u2019s Home windows sandbox documentation calls the elevated mode the popular native setup. It makes use of lower-privilege sandbox customers. It additionally makes use of filesystem boundaries, firewall guidelines, and native coverage adjustments. The non-admin mode exists for machines the place elevation is unavailable. Nonetheless, it presents weaker safety.<\/p>\n

8. Ship a protected first immediate<\/h3>\n

As soon as the immediate seems, begin with a read-only process. This confirms that Codex can see the repository. It doesn’t ask the instrument to change something.<\/p>\n

Clarify this repository’s construction. Don’t change any information. Then record the three instructions I ought to run to confirm it domestically.<\/p>\n

\n
\"Codex
The immediate seems after account, folder, and sandbox setup end<\/figcaption><\/figure>\n<\/div>\n

Helpful Instructions After Setup<\/h2>\n

\/standing: present the mannequin, listing, account, and energetic settings.<\/p>\n

\/permissions: examine or change what Codex can learn, edit, or run.<\/p>\n

\/mannequin: select the mannequin and reasoning effort out there to your account.<\/p>\n

\/init: create an AGENTS.md file for repository-specific directions.<\/p>\n

\/overview: overview adjustments earlier than you commit them.<\/p>\n

\/exit: go away the CLI cleanly.<\/p>\n

Preserve the default workspace boundary except the duty wants extra entry. The permissions documentation explains the read-only, workspace, and full-access profiles.<\/p>\n

Updating Codex CLI<\/h2>\n

For a standalone set up, rerun the platform installer. OpenAI makes use of the identical command for set up and updates.<\/p>\n

# macOS or Linux
\ncurl -fsSL https:\/\/chatgpt.com\/codex\/set up.sh | sh<\/p>\n

# Home windows PowerShell
\npowershell -ExecutionPolicy ByPass -c “irm https:\/\/chatgpt.com\/codex\/set up.ps1 | iex”<\/p>\n

Replace package-manager installs by means of the identical supervisor:<\/p>\n

# Homebrew
\nbrew improve –cask codex<\/p>\n

# npm
\nnpm set up -g @openai\/codex@newest<\/p>\n

End with codex –version to verify the put in construct.<\/p>\n

Conclusion<\/h2>\n

Putting in Codex CLI comes down to a few strikes:<\/p>\n

An set up command<\/p>\n

Single account approval<\/p>\n

A workspace and sandbox resolution<\/p>\n

The one genuinely unhealthy setup is the handy one within the fallacious listing. Launch from the repository, preserve the sandbox boundary, examine \/permissions, and start with a read-only instruction.<\/p>\n

As soon as that’s clear, run \/init and let the undertaking carry its personal guidelines.<\/p>\n
