## Why The app server is long-lived, but its shared model cache otherwise refreshes only when a caller needs it. Once the five-minute cache expires, starting a thread or calling `model/list` can wait for `/models` on the request path. Refresh the cache in the background before it expires so foreground callers normally use fresh local state. ## What changed - Start an app-server worker that refreshes models immediately and then every three minutes using the existing models-manager API. - Hold only a weak reference to the models manager between refreshes, so the worker does not extend its lifetime. - Stop scheduling refreshes when the app-server lifecycle handle is shut down or dropped. A refresh already in progress is allowed to finish. - Adjust affected app-server test fixtures to distinguish the background `/models` probe from the connection they are testing. The existing models-manager cache, refresh strategies, auth handling, ETag behavior, and concurrency semantics are unchanged. ## Testing - `models_refresh_worker::tests::refreshes_immediately_periodically_and_stops_when_dropped` - `suite::v2::remote_control::listen_off_honors_persisted_remote_control_enable` - `suite::v2::attestation::attestation_generate_round_trip_adds_header_to_responses_websocket_handshake`
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.
