## Why `codex sandbox` previously required an OS subcommand like `linux`, `macos`, or `windows`, even though the command can only run the sandbox backend available on the current host. That made the CLI imply a cross-OS choice that does not exist. ## What changed - Collapse `codex sandbox <os>` into `codex sandbox [COMMAND]...` by wiring the `sandbox` parser directly to the host-specific backend args with `cfg`. - Keep the existing backend runners for Seatbelt, Linux sandbox, and Windows restricted token. - Rename the public Windows debug sandbox runner to `run_command_under_windows_sandbox` for clarity. - Update the Rust sandbox docs and related README references to describe host OS selection and avoid pointing readers at legacy `sandbox_mode` config. ## Arg0 compatibility The `codex-linux-sandbox` helper path is still handled before normal CLI parsing. `arg0_dispatch()` checks whether the executable basename is `codex-linux-sandbox` and directly calls `codex_linux_sandbox::run_main()`, so removing the `sandbox linux` parser branch does not affect the arg0 helper flow. ## Verification - `cargo test -p codex-cli` - `cargo test -p codex-arg0` - `just fix -p codex-cli`
npm i -g @openai/codex
or brew install --cask codex
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
Install globally with your preferred package manager:
# 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
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
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.
