## What changed - The thread-resume replay tests now use unchecked mock sequencing so the replay flow can complete before the test asserts. - They also poll outbound `/responses` request counts and fail immediately if replay emits an unexpected extra request. ## Why this fixes the flake - The previous version asserted while the replay machinery was still mid-flight, so the test was sometimes checking an intermediate state instead of the completed behavior. - Strict mock sequencing made that problem worse by forcing the test to care about exact sub-step timing rather than about the end result. - Letting replay settle and then asserting on stabilized request counts makes the test validate the real contract: the replay path finishes and does not send extra model requests. ## Scope - Test-only change.
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.
