## Why Taking a step to removing the `persistExtendedHistory` field. It's not scalable to be persisting so much data in the rollout file and returning it in the thread history. When a client explicitly sends `true`, the server now tells that client the parameter is deprecated and ignored so the caller has a clear migration signal via the `deprecationNotice` notification. ## What changed - Keep the `persist_extended_history` / `persistExtendedHistory` field in the v2 protocol for compatibility, but document it as deprecated and ignored. - Ignore the parameter in app-server `thread/start`, `thread/resume`, and `thread/fork`; those paths always use limited history persistence now. - Stop treating `persistExtendedHistory` as a running-thread resume override mismatch. - Emit a connection-scoped `deprecationNotice` when a request explicitly sets `persist_extended_history: true`. ## Verification - Added `thread_start_deprecates_persist_extended_history_true` to cover the deprecation notice. - `cargo test -p codex-app-server` - `cargo test -p codex-app-server-protocol`
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.
