## Why Linux release jobs build the MUSL artifacts that ship in Codex releases, including both the primary CLI bundle and the app-server bundle. Those builds should run on the Codex Linux runner pools instead of generic Ubuntu-hosted runners so release builds use the x64 and arm64 capacity intended for Codex artifacts. ## What Changed - Moves the `x86_64-unknown-linux-musl` release matrix entries in `.github/workflows/rust-release.yml` from `ubuntu-24.04` to `codex-linux-x64-xl`. - Moves the `aarch64-unknown-linux-musl` release matrix entries from `ubuntu-24.04-arm` to `codex-linux-arm64`. - Leaves macOS release jobs, target triples, bundle names, and artifact names unchanged. ## Verification - Reviewed the workflow matrix diff for `.github/workflows/rust-release.yml`. - Not run locally; this is a GitHub Actions runner configuration change.
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.
