**note**: a large chunk of this diff comes from regenerating Python types after app-server schema changes on `main`. This is PR 3 of 3 for the Python SDK PyPI publishing split. PR #18862 refreshed the generated SDK surface, and PR #18865 made the runtime package publishable as `openai-codex-cli-bin`; this final PR makes the SDK package publishable as `openai-codex-app-server-sdk` and pins both packages to the same Codex runtime version. The key idea is that the published SDK version is the Codex runtime version. That one version now drives the SDK package version, the exact runtime dependency, the client version reported by the SDK, and the bootstrap runtime pin. This keeps release-time versioning in one lane instead of scattering checked-in literals through the package. ## What changed - Rename the SDK distribution from `codex-app-server-sdk` to `openai-codex-app-server-sdk` for conflict-free PyPI publishing. - Use `stage-sdk --codex-version ...` with one Codex version for both the SDK package version and exact `openai-codex-cli-bin` dependency. - Preserve hidden legacy `--runtime-version` / `--sdk-version` args only to reject mismatched versions during staging. - Map PEP 440 package versions back to Codex release tags for runtime setup downloads, e.g. `0.116.0a1` -> `rust-v0.116.0-alpha.1`. - Derive `codex_app_server.__version__`, the default `AppServerConfig.client_version`, and `_runtime_setup.pinned_runtime_version()` from the SDK package/project version instead of hardcoding duplicate version strings. - Carry the current generated SDK refresh from `main` so `generate-types` stays clean after recent app-server schema changes. - Update `sdk/python/uv.lock` for the renamed editable package. ## Validation - `uv run --extra dev pytest` in `sdk/python` -> 59 passed, 37 skipped. - Targeted `uv run ruff check` for the touched SDK files. - `git diff --check`. - Staged runtime with `--codex-version rust-v0.116.0-alpha.1 --platform-tag macosx_11_0_arm64`. - Staged SDK with `--codex-version rust-v0.116.0-alpha.1`. - Built runtime wheel, SDK wheel, and SDK sdist. - `twine check /tmp/codex-python-pr3-build/dist/*` -> passed. - Clean venv smoke installed `openai-codex-app-server-sdk==0.116.0a1` from local dist and pulled `openai-codex-cli-bin==0.116.0a1`. - Smoke imports passed for `Codex` and `bundled_codex_path()`.
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.
