iblai-router

A zero-dependency proxy that sits between OpenClaw and the Anthropic API, routing each request to the cheapest capable model using a 14-dimension weighted scorer (<1ms overhead).

Install

Run the install script to set up everything automatically:

CODEBLOCK0

This will:

1. 1. Copy server.js and config.json to INLINECODE2
2. Create and start a systemd service (iblai-router) on port 8402
3. Register iblai-router/auto as an OpenClaw model provider

After install, iblai-router/auto is available anywhere OpenClaw accepts a model ID.

Verify

CODEBLOCK1

Use

Set iblai-router/auto as the model for any scope:

Tip: Keep the main interactive session on a fixed model (e.g. Opus). Use the router for cron jobs, subagents, and background tasks where cost savings compound.

Customize

All config lives in ~/.openclaw/workspace/router/config.json and hot-reloads on save — no restart needed.

Models

Change the models per tier:

CODEBLOCK2

Non-Anthropic models (OpenAI, Google)

Set apiBaseUrl to route through OpenRouter:

CODEBLOCK3

Update the API key in the systemd service when switching providers, then systemctl daemon-reload && systemctl restart iblai-router.

Scoring

Keyword lists control which tier handles a request:

• - simpleKeywords, relayKeywords → push toward LIGHT (cheap)
• INLINECODE17, codeKeywords, agenticKeywords → push toward MEDIUM
• INLINECODE20, reasoningKeywords, domainKeywords → push toward HEAVY (capable)

Tune boundaries and weights in config.json to match your workload. See the full README for details.

Uninstall

CODEBLOCK4

Stops the service, removes the systemd unit, and deletes router files. Reminder: switch any workloads using iblai-router/auto back to a direct model first.
