## Summary - Retire the experimental TUI2 implementation and its feature flag. - Remove TUI2-only config/schema/docs so the CLI stays on the terminal-native path. - Keep docs aligned with the legacy TUI while we focus on redraw-based improvements. ## Customer impact - Retires the TUI2 experiment and keeps Codex on the proven terminal-native UI while we invest in redraw-based improvements to the existing experience. ## Migration / compatibility - If you previously set tui2-related options in config.toml, they are now ignored and Codex continues using the existing terminal-native TUI (no action required). ## Context - What worked: a transcript-owned viewport delivered excellent resize rewrap and high-fidelity copy (especially for code). - Why stop: making that experience feel fully native across the environment matrix (terminal emulator, OS, input modality, multiplexer, font/theme, alt-screen behavior) creates a combinatorial explosion of edge cases. - What next: we are focusing on redraw-based improvements to the existing terminal-native TUI so scrolling, selection, and copy remain native while resize/redraw correctness improves. ## Testing - just write-config-schema - just fmt - cargo clippy --fix --all-features --tests --allow-dirty --allow-no-vcs -p codex-core - cargo clippy --fix --all-features --tests --allow-dirty --allow-no-vcs -p codex-cli - cargo check - cargo test -p codex-core - cargo test -p codex-cli
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 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.
