When Does Multi-Agent RL Improve LLM Workflows? Workflow, Scale, and Policy-Sharing Tradeoffs
arXiv:2605.24202v1 Announce Type: cross Abstract: Multi-agent LLM workflows route inference through specialized roles to lift end-task accuracy, but jointly training those roles with reinforcement learning is unstable in ways that are poorly understood. We study when end-to-end RL training of multi-agent LLM workflows improves over their base models, comparing Shared-Policy training, where all roles update one policy, with Isolated-Policy training, where each role has its own parameters. Our experimental matrix spans Eval-Opt, Voting, and Orch-Workers workflows, math and code tasks, and three
The rapid development of large language models and the increasing complexity of AI tasks necessitate more efficient and robust training methodologies for multi-agent systems.
Improving the stability and effectiveness of multi-agent reinforcement learning for LLMs is crucial for developing advanced, autonomous AI agents capable of complex decision-making and workflow automation.
This research provides insights into optimizing training approaches for multi-agent LLM workflows, potentially leading to more reliable and scalable AI systems.
