This updates remote `exec-server` registration to use normal Codex auth instead of a registry-issued credential. The registry request is built from the existing auth-provider path, which preserves the biscuit-only registry contract introduced in [openai/openai#924101](https://github.com/openai/openai/pull/924101) while removing the old remote registry bearer env var and its direct transport assumptions. The default remote flow uses persisted ChatGPT auth from the normal Codex config/storage path. This PR also includes the containerized Agent Identity path needed by [openai/openai#924260](https://github.com/openai/openai/pull/924260): remote `exec-server` accepts `--allow-agent-identity-auth`, permits Agent Identity auth loaded from `CODEX_ACCESS_TOKEN` only when that flag is present, and reuses the existing Agent task registration plus derived `AgentAssertion` header generation. API-key auth remains unsupported, and Agent Identity stays opt-in. Validation performed beyond normal presubmit coverage: - `cargo fmt --all --check` - `cargo check -p codex-cli` - `cargo test -p codex-exec-server` - `cargo test -p codex-cli exec_server_agent_identity_auth_flag_` - `cargo test -p codex-cli remote_exec_server_auth_mode_` I also attempted `cargo test -p codex-cli`. The new CLI tests passed inside that run, but the suite ended on an unrelated local marketplace-state failure in `plugin_list_excludes_unconfigured_repo_local_marketplaces`.
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.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
