Reward Modeling for Multi-Agent Orchestration

arXiv:2606.13598v1 Announce Type: cross Abstract: Multi-Agent Systems (MAS) built on Large Language Models (LLMs) require effective orchestration to coordinate specialized agents, yet training such orchestrators is hindered by limited supervision and high computational cost. We propose Orchestration Reward Modeling (OrchRM), a self-supervised framework for evaluating orchestration quality without human annotations. OrchRM leverages intermediate artifacts from multi-agent executions to construct win-lose pairs for Bradley-Terry reward model training. Unlike existing MAS test-time scaling and or

Why this matters
Why now

The rapid development and deployment of LLMs necessitate more efficient and scalable methods for training multi-agent systems, moving beyond labor-intensive human supervision.

Why it’s important

This development addresses a key bottleneck in scaling AI agent systems by enabling self-supervised training, which is crucial for building more autonomous and complex AI applications.

What changes

The reliance on human annotations for evaluating multi-agent orchestration is significantly reduced, potentially accelerating the development and deployment cycles of AI agents.
