Codex settings
Key Points
- Prevent sleep for long runs
- Switch detail level for verbosity
- Set tone and custom instructions
Summary
Codex settings (access from the bottom-left menu) let you control runtime behavior and UI verbosity. For first use, focus on four settings: Personalization, Prevent sleep, Detail level, and Appearance (avatar). Start conservatively with permissions and adjust as you learn the workflows you need.
Key Points
- Access settings from the bottom-left menu in Codex.
- Prevent sleep while running keeps your computer awake for long tasks to avoid Codex stopping.
- Detail level: use Coding mode to see specific commands Codex executes; switch to Default for a cleaner conversation.
- Personalization: choose tone (friendly or direct) and add custom instructions similar to ChatGPT.
- Appearance > Avatar: place a draggable avatar to monitor background tasks and return to Codex by selecting it.
- Start with a few key settings and conservative permissions; iterate as you learn what Codex should do.
