iblai-router

# 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: ```bash bash "$(dirname "$0")/scripts/install.sh" ``` This will: 1. Copy `server.js` and `config.json` to `~/.openclaw/workspace/router/` 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 ```bash curl -s http://127.0.0.1:8402/health | jq . curl -s http://127.0.0.1:8402/stats | jq . ``` ## Use Set `iblai-router/auto` as the model for any scope: | Scope | How | |---|---| | Cron job | Set `model` to `iblai-router/auto` in job config | | Subagents | `agents.defaults.subagents.model = "iblai-router/auto"` | | Per-session | `/model iblai-router/auto` | | All sessions | `agents.defaults.model.primary = "iblai-router/auto"` | **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: ```json { "models": { "LIGHT": "claude-haiku-4-5", "MEDIUM": "claude-sonnet-5", "HEAVY": "claude-opus-4-8" } } ``` ### Models from other providers (per tier) Each tier can point at a different provider. A `providers` map defines the upstream (`baseUrl`, `apiKeyEnv`, `auth`), and any tier can be an object `{ "provider": "...", "model": "..." }` instead of a bare string. Providers must speak the **Anthropic Messages API** format (native, or via an Anthropic-compatible gateway such as OpenRouter, z.ai, or Moonshot): ```json { "defaultProvider": "anthropic", "providers": { "anthropic": { "baseUrl": "https://api.anthropic.com", "apiKeyEnv": "ANTHROPIC_API_KEY", "auth": "x-api-key" }, "openrouter": { "baseUrl": "https://openrouter.ai/api/v1", "apiKeyEnv": "OPENROUTER_API_KEY", "auth": "bearer" }, "zai": { "baseUrl": "https://api.z.ai/api/anthropic", "apiKeyEnv": "ZAI_API_KEY", "auth": "x-api-key" } }, "models": { "LIGHT": { "provider": "openrouter", "model": "google/gemini-2.5-flash" }, "MEDIUM": { "provider": "openrouter", "model": "openai/gpt-5.1" }, "HEAVY": "claude-opus-4-8" } } ``` Set the matching `apiKeyEnv` in the systemd service (the install script passes through `OPENROUTER_API_KEY`, `OPENAI_API_KEY`, `GOOGLE_API_KEY`, `ZAI_API_KEY`, `MOONSHOT_API_KEY` if present), then `systemctl daemon-reload && systemctl restart iblai-router`. ### Scoring Keyword lists control which tier handles a request: - `simpleKeywords`, `relayKeywords` → push toward **LIGHT** (cheap) - `imperativeVerbs`, `codeKeywords`, `agenticKeywords` → push toward **MEDIUM** - `technicalKeywords`, `reasoningKeywords`, `domainKeywords` → push toward **HEAVY** (capable) Tune boundaries and weights in `config.json` to match your workload. See the [full README](https://github.com/iblai/iblai-openclaw-router) for details. ## Uninstall ```bash bash "$(dirname "$0")/scripts/uninstall.sh" ``` 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.
