## AI 摘要

AWS 论文提出 UnitBoost，用任务给定的 unit map 将 worker 输出转为槽值提案，以受限 argmax 组装结果，未填充或不支持的槽位形成显式残差指导下一轮，从而无需生成式 meta-agent 来管理复合 LLM 系统。

## 正文

Great paper from AWS.

I use a similar setup where an agent orchestrator sits on top of a multi-agent system.

(bookmark it)

This work introduces one of the many approaches available to manage compound LLM systems.

Compound LLM systems usually solve coordination by adding a higher-level model.

That meta-agent reads worker outputs, writes the final answer, allocates later calls and decides when to stop, which concentrates three separate control decisions in one opaque, order-sensitive call.

UnitBoost investigates whether the manager needs to be generative at all.

A task-given unit map turns worker outputs into slot-value proposals, a constrained argmax assembles the output, and slots left unfilled or unsupported become an explicit residual that directs the next round.

On three held-out benchmarks it beats the best single candidate chosen with gold labels by 0.060 to 0.195 task-score points, and beats input-matched generative managers by 0.048 to 0.076.

Replacing only the management step improves six compound-system configurations. Residual-directed rounds raise FanOutQA cell F1 from 0.4778 to 0.5524.
