What codex does

Codex CLI brings the power of OpenAI's advanced coding models directly to your local terminal environment. It allows developers to generate, edit, and thoroughly explain code using natural language commands without ever leaving their active workspace. The tool can be installed as a standalone CLI application or integrated tightly into modern IDEs like VS Code and Cursor for a seamless experience. It significantly streamlines the development process by acting as an always-available AI pair programmer. The CLI offers a desktop app-like experience and gracefully falls back to GitHub releases if direct downloads are unavailable.

The Codex CLI is for software developers and system administrators who prefer command-line interfaces and want AI assistance natively in their terminal. It requires an active OpenAI API key and basic terminal proficiency.

Natural language execution: translates plain English commands directly into executable code or terminal operations.
In-place code editing: allows developers to modify existing files by describing the desired changes to the AI.
Local workspace integration: operates directly within the developer's terminal environment without requiring context switching.
IDE compatibility: provides hooks for integration into popular editors like VS Code and Cursor.
Graceful fallback mechanisms: ensures consistent availability by pulling from GitHub releases if primary download servers fail.

Where teams use it

Terminal Automation

Developers who want to execute complex bash commands or scripts by describing their intent in natural language.

Rapid Script Generation

Engineers needing to quickly scaffold boilerplate code or utility scripts without leaving the command line.

Code Explanation

Users seeking immediate, contextual explanations for unfamiliar code snippets directly within their terminal session.

AI Pair Programming

Programmers integrating an AI assistant into their daily workflow to handle repetitive refactoring tasks.

Getting started: curl -fsSL https://chatgpt.com/codex/install.sh | sh

README

main branch

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.

Quickstart

Installing and running Codex CLI

Run the following on Mac or Linux to install Codex CLI:

curl -fsSL https://chatgpt.com/codex/install.sh | sh

Run the following on Windows to install Codex CLI:

powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"

The standalone installers download from https://releases.openai.com/codex by default and fall back to GitHub Releases if a metadata or asset download is unavailable. To force GitHub Releases, set CODEX_INSTALLER_USE_RELEASES_OPENAI_COM to false (0 and no are also accepted):

curl -fsSL https://chatgpt.com/codex/install.sh | CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false sh

$env:CODEX_INSTALLER_USE_RELEASES_OPENAI_COM='false'; irm https://chatgpt.com/codex/install.ps1 | iex

Codex CLI can also be installed via the following package managers:

# Install using npm
npm install -g @openai/codex

# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

macOS
- Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
- x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
Linux
- x86_64: codex-x86_64-unknown-linux-musl.tar.gz
- arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.

Using Codex with your ChatGPT plan

Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.

You can also use Codex with an API key, but this requires additional setup.
