# fast Use fast when priority processing matters for your OpenAI Codex requests in Pi. It requests OpenAI Codex priority service only while enabled and an OpenAI Codex model is selected. ## Start Install or update through [Installation](../../README.md#install), then restart Pi after rebuilding. Enable fast in your Pi user settings, then select an OpenAI Codex model in `/model`. ```json { "fast": { "enable": true } } ``` The setting is off by default. Set `fast.enable` to `false` to return to normal service. A lightning-bolt status indicator appears while fast is active in an interactive Pi session. Trusted project settings can override user settings. Untrusted project settings are ignored. ## Reference ### Setting names | Setting | | --- | | `fast.enable` | [Changelog](./CHANGELOG.md).
