## Why `rust-release` cache restore has had very low practical value, while cache save consistently costs significant time (usually adding ~3 minutes to the critical path of a release workflow). From successful release-tag runs with cache steps (`289` runs total): - Alpha tags: cache download averaged ~5s/run, cache upload averaged ~230s/run. - Stable tags: cache download averaged ~5s/run, cache upload averaged ~227s/run. - Windows release builds specifically: download ~2s/run vs upload ~169-170s/run. Hard step-level signal from the same successful release-tag runs: - Cache restore (`Run actions/cache`): `2,314` steps, total `1,515s` (~0.65s/step). - `95.3%` of restore steps finished in `<=1s`; `99.7%` finished in `<=2s`; `0` steps took `>=10s`. - Cache save (`Post Run actions/cache`): `2,314` steps, total `66,295s` (~28.65s/step). Run-level framing: - Download total was `<=10s` in `288/289` runs (`99.7%`). - Upload total was `>=120s` in `285/289` runs (`98.6%`). The net effect is that release jobs are spending time uploading caches that are rarely useful for subsequent runs. ## What Changed - Removed the `actions/cache@v5` step from `.github/workflows/rust-release.yml`. - Removed the `actions/cache@v5` step from `.github/workflows/rust-release-windows.yml`. - Left build, signing, packaging, and publishing flow unchanged. ## Validation - Queried historical `rust-release` run/job step timing and compared cache download vs upload for alpha and stable release tags. - Spot-checked release logs and observed repeated `Cache not found ...` followed by `Cache saved ...` patterns.
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 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.
