pi-pioneer-provider

A Pi provider extension that connects to Pioneer AI's OpenAI-compatible API.

Installation

Install the package via Pi's package manager:

pi install npm:pi-pioneer-provider

Or pin to a specific version:

pi install npm:[email protected]

Authentication

Choose one of the following methods:

1. Interactive Login (Recommended)

Run /login inside Pi, select Pioneer AI, and enter your API key when prompted. The key is stored securely by Pi's auth system.

2. Environment Variable

Set the PIONEER_API_KEY environment variable before starting Pi:

export PIONEER_API_KEY=pio_sk_xxxxxxxxxxxxxxxx
pi

Supported Models

Models are discovered dynamically at startup from Pioneer's /base-models endpoint. Only chat-capable decoder models with inference support are exposed.

The following model capabilities are reported:

• Reasoning: Enabled for all discovered models
• Context window: Fetched from Pioneer API
• Max tokens: Set to min(context_window / 4, 131072)

Configuration

The provider uses https://api.pioneer.ai/v1 as the default base URL. You can override it via the PIONEER_BASE_URL environment variable:

export PIONEER_BASE_URL=https://your-custom-endpoint.com/v1

Usage

After installation and authentication, select a Pioneer model via /model or Ctrl+L inside Pi.

Example prompt:

Write a TypeScript function that fetches JSON from an API and retries on failure.
