Michael Bolin 110b30d545 install: consume Codex package archives (#23636)
## Summary

Standalone installs should exercise the same canonical package archive
layout that release builds produce, rather than unpacking npm platform
packages and reconstructing a parallel install tree.

This updates `install.sh` and `install.ps1` to prefer
`codex-package-<target>.tar.gz` plus `codex-package_SHA256SUMS`
introduced in https://github.com/openai/codex/pull/23635, authenticate
the checksum manifest against GitHub release metadata, verify the
selected package archive against the authenticated manifest, and install
the package archive directly.

## Compatibility Notes

Package installs still leave a compatibility command at `current/codex`
for managed daemon flows, while visible command shims point at
`bin/codex` inside the package layout.

Recent releases that predate package archives still publish per-platform
npm artifacts, so both installers keep a legacy platform npm fallback
for those versions and verify those archives against release metadata
directly.

Releases old enough to publish only the single root
`codex-npm-<version>.tgz` archive are intentionally out of scope. The
installers fail clearly when neither package archives nor per-platform
npm archives are present.

On Windows, the runtime helper lookups now recognize package-layout
installs where `codex.exe` runs from `bin/`, so
`codex-command-runner.exe` and `codex-windows-sandbox-setup.exe` resolve
from the top-level `codex-resources/` directory. The direct-sibling and
older sibling-resource fallbacks are preserved.

## Test plan

- `sh -n scripts/install/install.sh`
- `bash -n scripts/install/install.sh`
- `pwsh -NoProfile -Command '$tokens=$null; $errors=$null; $null =
[System.Management.Automation.Language.Parser]::ParseFile("scripts/install/install.ps1",
[ref]$tokens, [ref]$errors); if ($errors.Count) { $errors | Format-List
*; exit 1 }'`
- `HOME="$home_dir" CODEX_HOME="$tmp_dir/codex-home"
CODEX_INSTALL_DIR="$bin_dir" PATH="$bin_dir:$PATH" sh
scripts/install/install.sh --release 0.125.0`
- Verified the 0.125.0 isolated install leaves the visible command
pointed at `current/codex` and includes the legacy `codex-resources/rg`
payload.
- `cargo test -p codex-windows-sandbox`
- `just fix -p codex-windows-sandbox`

npm i -g @openai/codex
or brew install --cask codex

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

Codex CLI splash


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
  • 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.
