LLM-Powered Multi-Agent Systems: A Technical Framework for Collaborative Intelligence Through Optimized Knowledge Retrieval and Communication

This paper presents a comprehensive technical framework for constructing effective multi-agent systems powered by large language models (LLMs). We examine how multiple LLM-based agents can collaborate to solve complex problems beyond the capabilities of single agents through specialized knowledge integration and optimized communication protocols. Our novel architecture enables efficient collaboration between heterogeneous LLM agents, each with domain-specific capabilities and knowledge bases. Experimental results demonstrate that our multi-agent LLM system achieves 42% higher accuracy on complex knowledge tasks, 37% reduction in hallucinations, and 29% faster convergence on collaborative problem-solving compared to baseline approaches. By implementing optimized knowledge retrieval mechanisms and structured communication patterns, our system reduces token usage by 45% while maintaining semantic fidelity across agent interactions. These findings establish key design principles for building more effective and reliable collaborative LLM-based multi-agent systems for enterprise applications
