OmniRoute Manager for Pi

A Pi Coding Agent extension that integrates OmniRoute — an AI gateway that routes requests across 44+ LLM providers with automatic fallback, load balancing, and cost optimization.

What it does

• Status bar shows which model actually served each response — e.g. CheapFix → gemini-2.5-flash-lite (gemini · Google Account)
• Combo preview on model switch — immediately shows the routing order before you send a message
• Startup warnings if any provider connections are expired or need re-authentication
• Combo management — toggle on/off and switch active model without leaving pi
• Provider browser — drill into providers to see accounts, connection health, and available models
• Model sync — push all OmniRoute models and combos to pi's Ctrl+P model picker
• Log review — analyse call history to find broken models, with replacement suggestions
• Add custom providers — register OpenAI-compatible providers not built into OmniRoute

Install

Option 1 — curl (quickest)

mkdir -p ~/.pi/agent/extensions
curl -o ~/.pi/agent/extensions/omniroute-manager.ts \
  https://raw.githubusercontent.com/oscar-haha/omniroute-pi-extension/main/omniroute-manager.ts

Option 2 — npm

npm install -g omniroute-pi-extension
cp "$(npm root -g)/omniroute-pi-extension/omniroute-manager.ts" \
  ~/.pi/agent/extensions/omniroute-manager.ts

Configure pi to use OmniRoute as a provider

Add an omni provider to ~/.pi/agent/models.json:

{
  "providers": {
    "omni": {
      "baseUrl": "http://localhost:20128",
      "api": "anthropic-messages",
      "apiKey": "YOUR_OMNIROUTE_API_KEY",
      "models": [
        { "id": "CheapFix", "name": "CheapFix" }
      ]
    }
  }
}

Find your OmniRoute API key in the OmniRoute dashboard under Settings → API Keys.

Then run /omni sync inside pi to populate the full model list automatically.

Start pi

The extension auto-loads. You'll see OmniRoute ready — N combos on startup.

Commands

| Command | Description | |---------|-------------| | /omni | Status dashboard — health, active combos, provider issues | | /omni toggle | Interactive combo manager — Space toggles ON/OFF, Enter sets active model, Esc exits | | /omni providers | Browse providers — select one to see accounts and available models | | /omni add-provider | Register an OpenAI-compatible provider not built into OmniRoute | | /omni sync | Sync all OmniRoute models and combos to pi's Ctrl+P picker | | /omni log-review | Analyse call history — flags broken models and suggests replacements | | /omni dashboard | Show OmniRoute web dashboard URL |

/omni toggle keyboard controls

↑ / ↓    Navigate combos
Space    Toggle combo ON / OFF
Enter    Set combo as active model immediately
Esc / q  Close

The status bar updates to show the combo's routing order as soon as you switch, and then updates again after each response to show which model actually ran.

/omni log-review

Fetches the last 200 call logs and analyses each model in each combo:

─── OpenSource [priority] ───
  ✅ groq/llama-3.3-70b-versatile     100% success · avg 380ms
  ⚠️  groq/llama-3.3-70b-versatile    context too large for free tier (8× 413) — works in shorter sessions
  ❌ openrouter/auto                  0/5 success · 403×1, 502×4 → suggest replace
  ⏱  nvidia/deepseek-ai/deepseek-v3.2 100% success · avg 49s (slow)
  ❓ nvidia/moonshotai/kimi-k2.5      (no history)

For each broken model (❌) it then prompts you to remove it or pick a replacement from the same provider or others — filtered to exclude models already in the combo.

How it works

Pi sends requests to OmniRoute, which routes them to the best available provider based on your combo strategy (priority, weighted, round-robin, least-used). After each response, the extension polls OmniRoute's call logs until it finds the entry for that turn, then displays the actual model and account in pi's status bar.

Combos

Combos are model groups with routing strategies. For example:

CheapFix [priority]:
  1. qw/qwen3-coder-flash       ← try first (free, fast)
  2. gemini/gemini-2.5-flash-lite
  3. groq/qwen/qwen3-32b
  4. kr/claude-sonnet-4.5       ← last resort fallback

Create and edit combos in the OmniRoute dashboard. Toggle them on/off or switch active model from pi with /omni toggle.

Custom providers

OmniRoute supports 44+ built-in providers. For others (like OpenAdapter), use /omni add-provider to register any OpenAI-compatible endpoint.
