Windows Terminal supports 24-bit color but `supports-color` often reports only ANSI-16 because `COLORTERM` is not set. Introduce `diff_color_level_for_terminal`, a pure mapping from detected color level to intended diff palette, that promotes to truecolor when Windows Terminal is detected. Detection uses two independent signals — `TerminalName::WindowsTerminal` (from `terminal_info()`) and raw `WT_SESSION` presence — so the promotion fires even if one detection path changes. When `WT_SESSION` is present, promotion is unconditional (including `Unknown` level); without it, only ANSI-16 is promoted for named WindowsTerminal sessions. Setting `FORCE_COLOR` suppresses both paths to preserve explicit user intent. All env reads stay in the thin `diff_color_level()` wrapper; the core function is pure for testability. Six unit tests cover every branch.
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.
