## Why Guardian auto-review normally uses the provider-preferred review model when one is available. Some parent models need model-catalog metadata to select a different review model while keeping older `/models` payloads compatible when that metadata is absent. ## What changed - Added optional `ModelInfo::auto_review_model_override` metadata to the public model payload as a review-model slug. - Updated Guardian review model selection to prefer the catalog override when present, while preserving the existing provider preferred-model path and parent-model fallback when it is omitted. - Added focused Guardian coverage for override and no-override model selection. - Added an `auto_review` core integration suite test that loads override metadata from a remote model catalog path and asserts the strict auto-review `/responses` request uses the catalog-selected review model. - Updated existing `ModelInfo` fixtures and local catalog constructors for the new optional field. ## Validation - `cargo test -p codex-protocol model_info_defaults_availability_nux_to_none_when_omitted` - `cargo test -p codex-core guardian_review_uses_` - `cargo test -p codex-core remote_model_override_uses_catalog_model_for_strict_auto_review --test all` - `just fix -p codex-protocol` - `just fix -p codex-core` - `just fmt` - `git diff --check`
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
