⚡ pi-service-tier

A pi extension that toggles fast mode and applies provider service tiers.

📦 Install

pi install npm:pi-service-tier

If you use pi-fancy-footer, you'll get a service tier widget in the footer:

✨ What it does

• Adds service tier parameters to supported provider requests when a tier is configured
• Adds /fast to toggle the current model provider between fast mode and off
• Adds /service-tier to configure all supported providers from an interactive modal
• Adds an optional service tier widget when pi-fancy-footer is installed

🚀 Commands

• /fast: toggles the current model provider between its fast tier and off. The supported providers all use priority as the fast tier.

• /service-tier: opens an interactive editor. The current model provider appears first, followed by the remaining supported providers. Press Enter or Space to cycle through off and the provider-specific tiers.

⚙️ Configure

Run /service-tier or create ~/.pi/agent/service-tier.json:

{
  "openai": "priority",
  "openai-codex": "flex",
  "anthropic": "priority",
  "google": "priority",
  "google-vertex": "flex"
}

Supported providers

Provider	Tiers	Fast tier
openai	flex, priority	priority
openai-codex	flex, priority	priority
anthropic	priority, standard	priority
google	flex, priority	priority
google-vertex	flex, priority	priority

To turn a provider off, omit its key. Only the values listed above are accepted. Batch APIs are separate asynchronous APIs and are not configured by this extension.

🧩 Footer widget

When pi-fancy-footer is installed, the widget appears only when the active model uses a supported provider/API pair and that provider has a configured tier.

The widget id is pi-service-tier.service-tier. It uses the current pi-fancy-footer extension widget API, with row 1, order 8, right alignment, and no grow behavior by default.

📝 TODO

• Account for service-tier pricing in pi usage metrics. The extension currently injects the tier into the provider request payload, but pi's OpenAI Codex cost calculation reads the requested tier from provider options. Until pi exposes a first-class extension path for that option, displayed usage costs can omit flex or priority multipliers.
