Beyond Self-Talk: A Communication-Centric Survey of LLM-Based Multi-Agent Systems

arXiv:2502.14321v3 Announce Type: replace-cross Abstract: Large language model-based multi-agent systems have recently gained significant attention due to their potential for complex, collaborative, and intelligent problem-solving capabilities. Existing surveys typically categorize LLM-based multi-agent systems (LLM-MAS) according to their application domains or architectures, overlooking the central role of communication in coordinating agent behaviors and interactions. To address this gap, this paper presents a comprehensive survey of LLM-MAS from a communication-centric perspective. Specifi

Why this matters
Why now

The rapid development and adoption of large language models are pushing the boundaries of autonomous system capabilities, making multi-agent systems a critical next step.

Why it’s important

Understanding communication in LLM-based multi-agent systems is crucial for scaling AI applications, enabling more complex problem-solving, and improving coordination efficiency.

What changes

The focus is shifting from individual LLM capabilities to how multiple LLMs can interact and communicate effectively, enhancing their collective intelligence and problem-solving through agentic systems.
