ClawRouter is an open-source LLM router for OpenClaw that classifies query complexity and routes requests to the cheapest capable model: DeepSeek for simple queries, Claude Sonnet for complex ones.

How much does ClawRouter save on API costs?

ClawRouter claims 78% reduction in inference costs. One user reported cutting a $4,660 Anthropic bill by 70% using smart routing.

What models does ClawRouter support?

ClawRouter supports 41+ models across OpenAI, Anthropic, Google, DeepSeek, and xAI. Routing happens locally in <1ms.

How does ClawRouter work?

ClawRouter uses 14-dimension weighted scoring to classify query complexity into 4 tiers: SIMPLE (DeepSeek, $0.27/M), MEDIUM (GPT-4o-mini), COMPLEX (Claude Sonnet), REASONING (o3). Routing runs locally with no external API calls.

Where can I install ClawRouter?

GitHub: github.com/BlockRunAI/ClawRouter — installs as an OpenClaw-compatible LLM proxy layer.

Product Idea from this Signal

A smart proxy that routes OpenClaw requests to the cheapest working model and fails over instantly without infinite loops

6.9k ▲

OpenClaw model failover is completely broken. When the primary model hits rate limits, LiveSessionModelSwitchError creates an infinite retry loop instead of switching to the fallback. The overloaded_error from Anthropic does not trigger failover at all. Meanwhile, users are paying 3-5x more than necessary because there is no intelligent routing between Claude Opus, Sonnet, GPT-4o, and DeepSeek V3 based on task complexity. This tool sits between OpenClaw and the LLM providers, routing each request to the optimal model by task type and instantly failing over to alternatives when any provider goes down.
