  • Multi-agent coordination improves performance on parallelizable tasks but degrades it on sequential ones.
  • Agentic tasks require sustained multi-step interactions, iterative information gathering, and adaptive strategy refinement.
  • Five canonical architectures were evaluated: single-agent (SAS), independent, centralized, decentralized, and hybrid.
  • Centralized coordination improved performance by 80.9% on parallelizable tasks like financial reasoning.
  • Multi-agent variants degraded performance by 39-70% on sequential tasks like planning.
  • Independent multi-agent systems amplified errors by 17.2x, while centralized systems contained amplification to 4.4x.
  • A predictive model was developed to identify the optimal architecture for 87% of unseen tasks.
  • The model uses task properties like tool count and decomposability to predict the best coordination strategy.
