## Why The Codex App has animated pets, but the TUI had no equivalent ambient companion surface. This brings that experience into terminal Codex while keeping the main chat flow usable: the pet should feel present, but it cannot cover transcript text, composer input, approvals, or picker content. The feature also needs to be terminal-aware. Different terminals support different image protocols, tmux can interfere with image rendering, and some users will want pets disabled entirely or anchored differently depending on their layout. <table> <tr><td> <img width="4110" height="2584" alt="CleanShot 2026-05-05 at 12 41 45@2x" src="https://github.com/user-attachments/assets/68a1fcbc-2104-48d6-b834-69c6aaa95cdf" /> <p align="center">macOS - Ghostty, iTerm2 and WezTerm with Custom Pet</p> </td></tr> <tr><td> ![Uploading CleanShot 2026-05-10 at 20.28.30.png…]() <p align="center">Windows Terminal</p> </td></tr> <tr><td> <img width="3902" height="2752" alt="CleanShot 2026-05-05 at 12 39 02@2x" src="https://github.com/user-attachments/assets/300e2931-6b00-467e-91cb-ab8e28470500" /> <p align="center">Linux - WezTerm and Ghostty</p> </td></tr> </table> ## What Changed - Add a TUI ambient pet renderer in `codex-rs/tui/src/pets/`. - Port the app-style pet animation states so the sprite changes with task status, waiting-for-input states, review/ready states, and failures. - Add `/pets` selection UI with a preview pane, loading state, built-in pet choices, and a first-row `Disable terminal pets` option. - Download built-in pet spritesheets on demand from the same public CDN path already used by Android, under `https://persistent.oaistatic.com/codex/pets/v1/...`, and cache them locally under `~/.codex/cache/tui-pets/`. - Keep custom pets local. - Add config support for pet selection, disabling pets, and choosing whether the pet follows the composer bottom or anchors to the terminal bottom. - Reserve layout space around the pet so transcript wrapping, live responses, and composer input do not render underneath the sprite. - Gate image rendering by terminal capability, disable image pets under tmux, and support both Kitty Graphics and SIXEL terminals. - Add redraw cleanup for terminal image artifacts, including sixel cell clearing. ## Current Scope - This is an initial TUI version of ambient pets, not full App parity. - It focuses on ambient sprite rendering, `/pets` selection, custom pets, terminal capability gating, and on-demand CDN-backed built-in assets. - The ambient text overlay is currently disabled, so the TUI renders the pet sprite without extra status text beside it. ## How to Test 1. Start Codex TUI in a terminal with image support. 2. Run `/pets`. 3. Confirm the picker shows built-in pets plus custom pets, and the first item is `Disable terminal pets`. 4. On a fresh `~/.codex/cache/tui-pets/`, move onto a built-in pet and confirm the first preview downloads the spritesheet from the shared Codex pets CDN and renders successfully. 5. Move through the pet list and confirm subsequent built-in previews use the local cache. 6. Select a pet, then send and receive messages. Confirm transcript and composer text wrap before the pet instead of rendering underneath the sprite. 7. Change the pet anchor setting and confirm the pet can either follow the composer bottom or sit at the terminal bottom. 8. Return to `/pets`, choose `Disable terminal pets`, and confirm the sprite disappears cleanly. Targeted tests: - `cargo test -p codex-tui ambient_pet_` - `cargo test -p codex-tui resize_reflow_wraps_transcript_early_when_pet_is_enabled` - `cargo insta pending-snapshots`
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.
