## Why The Python and TypeScript SDKs launch the native Codex runtime directly, so they need to consume the same package artifact shape that release jobs now produce. The runtime wheel should be built from the canonical Codex package archive rather than reconstructing a parallel layout from loose binaries. ## What Changed - Stage `openai-codex-cli-bin` by extracting `codex-package-<target>.tar.gz` into `src/codex_cli_bin` and validating the expected package layout. - Update release workflows to pass the generated package archive into `stage-runtime` instead of the temporary package directory. - Update Python runtime setup to download `codex-package-*.tar.gz` release assets directly. - Expose Python runtime helpers for the bundled package directory and `codex-path`, and prepend that path when `openai_codex` launches the installed runtime without duplicating Windows `Path`/`PATH` keys. - Teach the TypeScript SDK to resolve package-layout optional dependencies while keeping the existing npm fallback layout, and preserve the existing Windows path variable casing when prepending `codex-path`. ## Test Plan - `python3 -m py_compile sdk/python/scripts/update_sdk_artifacts.py sdk/python/_runtime_setup.py sdk/python/src/openai_codex/client.py sdk/python-runtime/src/codex_cli_bin/__init__.py` - `uv run --frozen --project sdk/python --extra dev ruff check sdk/python/scripts/update_sdk_artifacts.py sdk/python/_runtime_setup.py sdk/python/src/openai_codex/client.py sdk/python/tests/test_artifact_workflow_and_binaries.py sdk/python-runtime/src/codex_cli_bin/__init__.py` - `uv run --frozen --project sdk/python --extra dev pytest sdk/python/tests/test_artifact_workflow_and_binaries.py` - `pnpm eslint src/exec.ts tests/exec.test.ts` - `pnpm test --runInBand tests/exec.test.ts`
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.
