Codex environments
Choose where a Codex chat runs and how its files stay isolated
In the ChatGPT desktop app, open the ChatGPT dropdown and select Codex. When starting a Codex chat, choose where it runs:
- Local: work directly in your current project directory.
- Worktree: isolate changes in a Git worktree. Learn more.
- Cloud: run remotely in a configured cloud environment.
Both Local and Worktree chats run on your computer.
