Pi Neuralwatt Extension

A Pi extension that adds Neuralwatt as a model provider, giving you access to open-source models through an OpenAI-compatible API with energy transparency.

Installation

Get API Key

Sign up at neuralwatt.com to get an API key.

Configure Credentials

The extension uses Pi's credential storage. Add your API key to ~/.pi/agent/auth.json (recommended):

{
  "neuralwatt": { "type": "api_key", "key": "your-api-key-here" }
}

Or set environment variable:

export NEURALWATT_API_KEY="your-api-key-here"

Install Extension

# From npm
pi install npm:@aliou/pi-neuralwatt

# From git
pi install git:github.com/aliou/pi-neuralwatt

# Local development
pi -e ./src/extensions/provider/index.ts

Usage

Once installed, select neuralwatt as your provider and choose from available models:

/model neuralwatt meta-llama/Llama-4-Maverick-17B-128E-Instruct-FP8

Quota Command

Check your API usage at a glance:

/neuralwatt:quota

The quota command shows three tabs:

  • Subscription (when subscribed) — plan details, energy quota with progress bar, billing period
  • Credits — credit balance with progress bar, accounting method
  • Usage & Key — monthly usage (cost, requests, tokens, energy), API key info, key allowance, rate limits

Quota Warnings

When enabled, the extension notifies you when credits or energy are running low. When you have an active subscription, only energy warnings fire (credits are on-demand top-up only). Warnings use escalation on severity transitions and have a cooldown for warning level.

Sub-bar Integration

When a Neuralwatt model is active, the footer status bar shows live quota usage (credits and energy). The status updates after each response and on session start.

Settings

Configure features with /neuralwatt:settings:

  • Quota command — Show/hide /neuralwatt:quota
  • Quota warnings — Enable/disable low quota notifications
  • Sub-bar integration — Show/hide usage in status bar

The provider itself cannot be disabled — it is always loaded.

Adding or Updating Models

Models are hardcoded in src/extensions/provider/models.ts and validated against the live API. To update:

  1. Run pnpm test — it fetches /v1/models and compares against hardcoded definitions
  2. Fix any discrepancies (missing models, changed context windows)
  3. Re-run pnpm test to confirm

Development

Setup

git clone https://github.com/aliou/pi-neuralwatt.git
cd pi-neuralwatt

# Install dependencies (sets up pre-commit hooks)
pnpm install && pnpm prepare

Pre-commit hooks run on every commit:

  • TypeScript type checking
  • Biome linting
  • Biome formatting with auto-fix

Commands

# Type check
pnpm run typecheck

# Lint
pnpm run lint

# Format
pnpm run format

# Test
pnpm run test

Release

This repository uses Changesets for versioning.

Requirements

  • Pi coding agent v0.67.68+
  • Neuralwatt API key (configured in ~/.pi/agent/auth.json or via NEURALWATT_API_KEY)
