Fixes #16092 The app-server-backed TUI could accumulate ghost subagent entries in `/agent` after resume/backfill flows. Some of those rows were no longer live according to the backend, but still appeared selectable in the picker and could open as blank threads. *Cause* Unlike the legacy tui behavior, tui_app_server was creating local picker/replay state for subagents discovered through metadata refresh and loaded-thread backfill, even when no real local session or transcript had been attached. That let stale ids survive in the picker as if they were replayable threads. *Fix* Stop creating empty local thread channels during subagent metadata hydration and loaded-thread backfill. When opening /agent, prune metadata-only entries that thread/read reports as terminally unavailable. When selecting a discovered subagent that is still live but not yet locally attached, materialize a real local session on demand from thread/read instead of falling back to an empty replay state.
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.
