## Why PR #20559 added opt-in strict config parsing to the config-loading command surfaces, but `codex exec-server` was left out. That meant `codex exec-server --strict-config` was rejected even though the command can load config for remote registration, and local server startup had no way to fail fast on misspelled config keys. ## What Changed - Added `--strict-config` to `codex exec-server`. - Allowed root-level inheritance from `codex --strict-config exec-server`. - Validated config before local exec-server startup when strict mode is requested. - Reused the loaded strict-config-aware config for remote exec-server registration auth. - Added CLI coverage showing `codex exec-server --strict-config` rejects unknown config fields. ## Verification - `cargo test -p codex-cli` - New integration test: `strict_config_rejects_unknown_config_fields_for_exec_server` ## Documentation Any strict-config command list on developers.openai.com/codex should include `codex exec-server` with the other supported config-loading entry points.
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.
