/fast toggle for pi that enables OpenAI priority service tier on configured models.

This extension does not change the model, thinking level, tools, or prompts. It only adds service_tier=priority to provider requests when fast mode is active and the current model matches the configured supported-model list.

Requires pi 0.57.0 or newer.

Install

pi install npm:@benvargas/pi-openai-fast

Or try without installing:

pi -e npm:@benvargas/pi-openai-fast

Usage

  • /fast toggles fast mode on or off.
  • /fast on explicitly enables fast mode.
  • /fast off explicitly disables fast mode.
  • /fast status reports the current fast-mode state.
  • --fast starts the session with fast mode enabled.
  • By default, fast mode persists across new pi sessions via a JSON config file.
  • Startup state comes from the selected config file, not from resumed session/thread history.

Example:

pi -e npm:@benvargas/pi-openai-fast --fast

Config

Config files follow the same project-over-global pattern as the other packages:

  • Project: <repo>/.pi/extensions/pi-openai-fast.json
  • Global: ~/.pi/agent/extensions/pi-openai-fast.json

If neither exists, the extension writes a default global config on first run.

Default config:

{
  "persistState": true,
  "active": false,
  "supportedModels": [
    "openai/gpt-5.4",
    "openai-codex/gpt-5.4"
  ]
}

Settings:

  • persistState: when true, /fast writes the current on/off state to config so it resumes in new pi sessions. Default: true.
  • active: persisted fast-mode state used on startup when persistState is enabled.
  • supportedModels: list of provider/model-id strings that should receive service_tier=priority.

Project config overrides global config. /fast on and /fast off write to the selected config file, so if a project config exists the remembered state is project-specific. If fast mode is enabled on a model that is not in supportedModels, the setting stays on but requests are left unchanged until you switch back to a configured model.

Notes

  • When persistState is enabled, the last /fast setting also carries across brand-new pi sessions.
  • Resumed sessions do not override the config-backed startup state.
  • On configured models, fast mode maps to OpenAI service_tier=priority.

Uninstall

pi remove npm:@benvargas/pi-openai-fast
