pi install npm:@arhen/pi-9router

Pi Coding Agent extension for 9router — AI routing proxy.

Registers 9router as a Pi provider with dynamic model discovery. Provider only, no web tools — use pi-web-access for web search/fetch.

Features

  • Auto-discovers models and combos from 9router /v1/models on startup
  • Registers 9router provider with dynamic base URL + API key
  • Cached discovery (fast startup, credential-fingerprinted)
  • models.dev metadata enrichment (context window, max tokens, input modalities)
  • Reasoning support (thinkingLevelMap → reasoning_effort)
  • Commands: /9router-status, /9router-models, /9router-config, /9router-reasoning, /9router-reload

Environment

Variable Default Description
NINE_ROUTER_BASE_URL http://localhost:20128 9router endpoint
NINE_ROUTER_API_KEY — API key if 9router requires auth
NINE_ROUTER_ENABLE_REASONING — 1/true to expose thinking levels

Config persists to ~/.pi/agent/9router-config.json (shared across Pi instances).

Commands

Command Purpose
/9router-config Configure base URL, API key, reasoning
/9router-status Connection status, model counts
/9router-models Browse models/combos and switch
/9router-reasoning Toggle thinking levels
/9router-reload Re-discover models

Why not pi-9router-ext?

pi-9router-ext bundles the same provider plus web tools (ninerouter_web_search, ninerouter_web_fetch) and web-route discovery (~1.2K tokens extra in context). This package is the provider flow only — same config file format, same env vars, so they're drop-in interchangeable.
