## Why The Python and TypeScript SDKs launch the native Codex runtime directly, so they need to understand the same package layout that the release artifacts now use. Without this, SDK runtime wheels would keep carrying only a loose `bin/codex` plus ad hoc helper binaries, the TypeScript SDK would keep resolving the legacy optional-dependency layout, and bundled `codex-path` tools such as `rg` would not be prepended when the SDK starts Codex. ## What Changed - Stage `openai-codex-cli-bin` from a Codex package directory, including `codex-package.json`, `bin/`, `codex-resources/`, and `codex-path/`. - Make `stage-runtime` package-dir-only; legacy loose-binary wrapping now happens in `_runtime_setup.py` before calling the staging script. - 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 legacy layout fallback, and preserve the existing Windows path variable casing when prepending `codex-path`. - Update the Rust release workflows to build Python runtime wheels from the generated Codex package directories instead of loose binaries. ## 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.
