Abstract: Recent advances in large language models (LLMs) demonstrate substantial
capabilities in natural language understanding and generation tasks. With the
growing number of LLMs, how to harness the collective expertise of multiple
LLMs is an exciting open direction. Toward this goal, we propose a new approach
that leverages the collective strengths of multiple LLMs through a
Mixture-of-Agents (MoA) methodology. In our approach, we construct a layered
MoA architecture wherein each layer comprises multiple LLM agents. Each agent
takes all the outputs from agents in the previous layer as auxiliary
information in generating its response. MoA models achieves state-of-art
performance on AlpacaEval 2.0, MT-Bench and FLASK, surpassing GPT-4 Omni. For
example, our MoA using only open-source LLMs is the leader of AlpacaEval 2.0 by
a substantial gap, achieving a score of 65.1% compared to 57.5% by GPT-4 Omni.
