@tifan/pi-fast-mode

Toggle OpenAI Fast Mode globally and track response TPS.

Install

pi install npm:@tifan/pi-fast-mode

Usage

Run /fast or press the configured shortcut to toggle Fast Mode globally. The shortcut defaults to Amp's speed.toggleFast keybinding. When that setting is empty or missing, the shortcut defaults to alt+r.

Fast Mode adds service_tier: "priority" to requests from supported openai and openai-codex models while enabled. When paired with @tifan/pi-minimal-footer, the active model shows a ↯ marker.

Run /tps to toggle response TPS.

When TPS is enabled, the status shows the latest response rate, median response rate, and median time to first token:

last 58 t/s · med 44 t/s | 2.1s ttft

Response TPS uses Pi's provider-reported output tokens divided by the time from turn start to assistant message end. It includes reasoning tokens and response wait time. It does not include time spent executing tools.

Configuration

Preferences are stored at $PI_CODING_AGENT_DIR/extensions/pi-fast-mode.json:

{
  "enabled": false,
  "toggleFast": "",
  "tpsEnabled": true
}

A non-empty toggleFast value overrides Amp's keybinding. Pi key syntax uses alt+r; the Amp-style spelling opt-r also works. If both settings are empty, Fast Mode uses alt+r.

Pi reads Amp's keybinding from amp.keymap["speed.toggleFast"] in ~/.config/amp/settings.json.

tpsEnabled defaults to true. Legacy models settings migrate to global mode based on whether the list was empty.
