## Why `codex-core` enabled `deterministic_process_ids` through a self dev-dependency. That forced a second feature-resolved build of the same crate, which increased compile time and test latency. ## What Changed - Removed the `deterministic_process_ids` feature from `codex-rs/core/Cargo.toml`. - Removed the self dev-dependency on `codex-core` that enabled that feature. - Removed the Bazel `deterministic_process_ids` crate feature for `codex-core`. - Added a test-only `AtomicBool` override in unified exec process-id allocation. - Added a test-support setter for that override and re-exported it from `codex-core`. - Enabled deterministic process IDs in integration tests via `core_test_support` ctor. ## Behavior - Production behavior remains random process IDs. - Unit tests remain deterministic via `cfg(test)`. - Integration tests remain deterministic via explicit test-support initialization. ## Validation - `just fmt` - `cargo test -p codex-core unified_exec::` - `cargo test -p codex-core --test all unified_exec -- --test-threads=1` - `cargo tree -p codex-core -e features` (verified the removed feature 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 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.
