Paper AbstractExpand

LLM-based autonomous agents have demonstrated strong capabilities in reasoning, planning, and tool use, yet remain limited when tasks require sustained coordination across roles, tools, and environments. Multi-agent systems address this through structured collaboration among specialized agents, but tighter coordination also amplifies a less explored risk: errors can propagate across agents and interaction rounds, producing failures that are difficult to diagnose and rarely translate into structural self-improvement. Existing surveys cover individual agent capabilities, multi-agent collaboration, or agent self-evolution separately, leaving the causal dependencies among them unexamined. This survey provides a unified review organized around four causally linked stages, which we term the LIFE progression: Lay the capability foundation, Integrate agents through collaboration, Find faults through attribution, and Evolve through autonomous self-improvement. For each stage, we provide systematic taxonomies and formally characterize the dependencies between adjacent stages, revealing how each stage both depends on and constrains the next. Beyond synthesizing existing work, we identify open challenges at stage boundaries and propose a cross-stage research agenda for closed-loop multi-agent systems capable of continuously diagnosing failures, reorganizing structures, and refining agent behaviors, extending current coordination frameworks toward more self-organizing forms of collective intelligence. By bridging these previously fragmented research threads, this survey aims to offer both a systematic reference and a conceptual roadmap toward autonomous, self-improving multi-agent intelligence.

LLM-based autonomous agents have become highly capable at individual tasks like planning and tool use, but they often struggle when forced to work together on complex, multi-step projects. While multi-agent systems attempt to solve this through collaboration, they introduce a new problem: when errors occur, they ripple through the system, making it difficult to pinpoint the cause and preventing the agents from learning how to improve. This paper, Beyond Individual Intelligence: Surveying Collaboration, Failure Attribution, and Self-Evolution in LLM-based Multi-Agent Systems, provides a unified framework to bridge these gaps and move toward truly self-improving, collective intelligence.

The LIFE Progression

To address the current fragmentation in research, the authors introduce the "LIFE" progression. This framework organizes the development of multi-agent systems into four causally linked stages:

Lay the capability foundation: Establishing the core reasoning and tool-use skills of individual agents.
Integrate agents through collaboration: Structuring how these agents interact and coordinate.
Find faults through attribution: Diagnosing where and why failures occur as they propagate through the system.
Evolve through autonomous self-improvement: Using those insights to refine behaviors and reorganize structures.

Understanding Causal Dependencies

A key contribution of this survey is the formal characterization of how these stages depend on one another. The authors argue that each stage acts as both a foundation for and a constraint on the next. By mapping these dependencies, the paper reveals why current systems often fail to evolve: if a system cannot accurately attribute a failure (the "Find" stage), it cannot effectively trigger the "Evolve" stage. This systematic approach helps researchers see that individual agent capability is not enough; the entire chain must be robust for the system to function as a self-organizing unit.

A Roadmap for Future Research

Beyond reviewing existing work, the authors identify critical open challenges that exist at the boundaries between these four stages. They propose a research agenda focused on creating "closed-loop" systems. Instead of treating collaboration and self-improvement as separate research threads, the authors advocate for systems that can continuously diagnose their own errors, reorganize their internal structures, and refine their behaviors in real-time. This conceptual roadmap aims to shift the field away from static coordination frameworks toward more autonomous, self-evolving forms of collective intelligence.
