## Why `main` recently needed [#17691](https://github.com/openai/codex/pull/17691) because code behind `cfg(not(debug_assertions))` was not being compiled by the Bazel PR workflow. Our existing CI only built the fast/debug configuration, so PRs could stay green while release-only Rust code still failed to compile. This PR adds a release-style compile check that is cheap enough to run on every PR. ## What Changed - Added a `verify-release-build` job to `.github/workflows/bazel.yml`. - Represented each supported OS once in that job's matrix: x64 Linux, arm64 macOS, and x64 Windows. - Kept the build close to fastbuild cost by using `--compilation_mode=fastbuild` while forcing Rust to compile with `-Cdebug-assertions=no`, which makes `cfg(not(debug_assertions))` true without also turning on release optimizations or debug-info generation. - Added comments in `.github/workflows/bazel.yml` and `scripts/list-bazel-release-targets.sh` to make the job's intent and target scope explicit. - Restored the Bazel repository cache save behavior to run after every non-cancelled job, matching [#16926](https://github.com/openai/codex/pull/16926), and removed the now-unused `repository-cache-hit` output from `prepare-bazel-ci`. - Reused the shared `prepare-bazel-ci` action from the parent PR so the new job does not duplicate Bazel setup boilerplate. ## Verification - Used `bazel aquery` on `//codex-rs/tui:codex-tui` to confirm the Rust compile still uses `opt-level=0` and `debuginfo=0` while passing `-Cdebug-assertions=no`. - Parsed `.github/workflows/bazel.yml` as YAML locally. - Ran `bash -n scripts/list-bazel-release-targets.sh`.
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.
