This is PR 2 of the Python SDK PyPI publishing split. [PR 1](https://github.com/openai/codex/pull/18862) refreshed the generated SDK bindings; this PR makes the runtime package itself publishable, and PR 3 will wire the SDK package/version pinning to this runtime package. ## Summary - Rename the runtime distribution to `openai-codex-cli-bin` while keeping the import package as `codex_cli_bin`. - Make the runtime package wheel-only and build `py3-none-<platform>` wheels instead of interpreter-specific wheels. - Add `stage-runtime --codex-version` and `--platform-tag` so release staging can produce the platform wheel matrix from Codex release tags. - Add focused artifact workflow tests for version normalization, platform tag injection, and runtime wheel metadata. ## Why Rename There is already an unofficial PyPI package, [`codex-bin`](https://pypi.org/project/codex-bin/), distributing OpenAI Codex binaries. Publishing the official SDK runtime dependency as `openai-codex-cli-bin` makes the ownership clear, avoids confusing the SDK-pinned runtime wheel with that unowned wrapper, and keeps the import package unchanged as `codex_cli_bin`. ## Tests - `uv run --extra dev pytest tests/test_artifact_workflow_and_binaries.py` -> 21 passed - `uv run --extra dev python scripts/update_sdk_artifacts.py stage-runtime /tmp/codex-python-pr2-rebased/runtime-stage /tmp/codex-python-pr2-rebased/codex --codex-version rust-v0.116.0-alpha.1 --platform-tag macosx_11_0_arm64` - `uv run --with build --extra dev python -m build --wheel /tmp/codex-python-pr2-rebased/runtime-stage` - `uv run --with twine --extra dev twine check /tmp/codex-python-pr2-rebased/runtime-stage/dist/openai_codex_cli_bin-0.116.0a1-py3-none-macosx_11_0_arm64.whl` ## Note - Full `uv run --extra dev pytest` currently fails because regenerating from schemas already on `main` adds new DeviceKey Python types. I left that generated catch-up out of this runtime-only PR.
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.
