 # MasRouter: Learning to Route LLMs for Multi-Agent Systems
 
+## 📰 News

 ## 🤔Why MasRouter?
 
-**MasRouter** expands llm routing to the multi-agent systems(MAS) *for the first time*. It leverages the powerful reasoning capabilities of LLM MAS, while also making it relatively cost-effective.

 **MasRouter** integrates all components of MAS into a unified routing framework. It employs collaboration mode determination, role allocation, and LLM routing through a cascaded controller network, progressively constructing a MAS that balances effectiveness and efficiency.
