\section{Conclusion}

\label{sec:conclusion}

We have presented Hanzo Chat, a multi-model conversational AI system that combines intelligent model routing, hierarchical persistent memory, and extensible tool integration through the Model Context Protocol. Our evaluation demonstrates that the combination of these three capabilities achieves performance exceeding any single model while significantly reducing costs. The hierarchical memory architecture enables conversations spanning hundreds of turns without degradation, addressing one of the most significant limitations of current LLM-based chat systems. Production deployment over 18 months with 500K+ conversations validates the practical viability of the approach. Hanzo Chat is available at \texttt{chat.hanzo.ai} and its architecture is documented for the research community.
