面对应用的模型不必是单一检查点；它可以是一支受治理的舰队。现有的服务系统管理检查点和副本，而多智能体框架组合模型调用时，未定义稳定的集体身份、效果权威或成员级演化。我们提出Fusion-MoA，一个运行时，将独立服务的异构Cells暴露为单个OpenAI兼容模型。版本化的Profile控制成员资格和证据准入；只读的Analysts提供有界证据，而唯一的Executor保留所有最终答案和工具权威。Cells可以被认证、提升或回滚，而无需更改公共API。我们通过三个操作见证评估了一个八Cell、三谱系的部署。在固定的HMMT P1-P10切片上，集体解决了8/10问题，而最强的单个Cell解决了6/10，且保留的轨迹显示少数知识转移到了三个最初错误或空的Cells。在20个Terminal-Bench 2.1任务中，所有工具操作仍可归属于一个Executor，零Analyst操作和零绕过效应。六个Cells被提升，一个不兼容的候选被本地回滚，而服务保持可用。Fusion-MoA证明了异构模型能力可以作为单一可观察、权威受限且独立可演化的服务来运营。
英文摘要
The model exposed to an application need not be a single checkpoint; it can be a governed fleet. Existing serving systems manage checkpoints and replicas, while multi-agent frameworks compose model calls without defining a stable collective identity, effect authority, or member-level evolution. We present Fusion-MoA, a runtime that exposes independently served heterogeneous Cells as one OpenAI-compatible model. A versioned Profile controls membership and evidence admission; read-only Analysts contribute bounded evidence, while a sole Executor retains all final-answer and tool authority. Cells can be qualified, promoted, or rolled back without changing the public API. We evaluate an eight-Cell, three-lineage deployment through three operational witnesses. On a fixed HMMT P1-P10 slice, the collective solves 8/10 problems versus 6/10 for the strongest individual Cell, and a preserved trace shows minority knowledge transferred to three initially incorrect or empty Cells. On 20 Terminal-Bench 2.1 tasks, all tool actions remain attributable to one Executor, with zero Analyst actions and zero bypass effects. Six Cells are promoted and one incompatible candidate is locally rolled back while the service remains available. Fusion-MoA demonstrates that heterogeneous model capability can be operated as one observable, authority-bounded, and independently evolvable service.
