@haoyiyin/9router

Pi extension — a 9Router provider (including OpenCode Free oc/ models) plus fetch, search, and transcribe tools.

A fork of @xynogen/pix-9router that fixes the issue where 9router's /v1/models never lists OpenCode Free -free models — this extension exposes those oc/ models directly.

Install

pi install npm:@haoyiyin/9router

Configure

There is no built-in default endpoint. Run /login, select 9Router, and enter the base URL and API key. They are saved to ~/.pi/agent/haoyiyin/9router.json (mode 0600). /logout removes the stored credential.

Environment variables are supported as a fallback: ROUTER_API_BASE / ROUTER_API_KEY (the config file takes precedence).

Combo models & thinking

Combo models (sub / free / main, owned_by: "combo") advertise no capabilities from the router, so their reasoning is decided by comboReasoning in ~/.pi/agent/haoyiyin/9router.json. It defaults to on (assumes combo routes hit thinking-capable upstreams) with the full off..max range. Opt out per machine with:

{
  "comboReasoning": false
}

To override that default range, pass a custom thinkingLevelMap (keys: off, minimal, low, medium, high, xhigh, max; values: what gets sent to the router, null hides the level). For example, to cap combo models at high:

{
  "comboReasoning": { "thinkingLevelMap": { "xhigh": null, "max": null } }
}

oc models

Every 30 minutes the extension fetches models from opencode.ai/zen/v1/models whose ids end in -free, and registers them under the 9router provider as oc/<id>. Changes to the upstream list are picked up automatically. Cache file: ~/.cache/pi/zen-oc-models.json.

Tools

fetch / search / transcribe behave the same as pix-9router; collapse config still lives in ~/.pi/agent/pix.json.
