## Why For npm/Bun-managed installs, the update prompt was treating the latest GitHub release as ready to install. During the `0.124.0` release, GitHub and npm visibility were not atomic: the root npm wrapper could become visible before the npm registry marked that version as the package `latest`. That left a window where users could be prompted to upgrade before npm was ready for the release. ## What changed - Keep GitHub Releases as the candidate latest-version source for npm/Bun installs, but only write the existing `version.json` cache after npm registry metadata proves that same root version is ready. - Add `codex-rs/tui/src/npm_registry.rs` to validate npm readiness by checking `dist-tags.latest` and root package `dist` metadata for the GitHub candidate version. - Move version parsing helpers into `codex-rs/tui/src/update_versions.rs` so that logic can be tested without compiling the release-only `updates.rs` module under tests. - Update `.github/workflows/rust-release.yml` so the six known platform tarballs publish before the root `@openai/codex` wrapper. Other npm tarballs publish before the root wrapper, and the SDK publishes after the root package it depends on.
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.
