Arena 评测：Jev Router 模型路由仍难兼顾成本与延迟
In summary, Jev Router makes smart choices. 4 of its 5 most-used models sit on the Pareto frontier, and its steerability is notably strong.
AI 导读
总的来说，Jev Router 做出了明智的选择。它最常用的 5 个模型中有 4 个位于帕累托前沿，其可控性也明显很强。 但这还不足以带来更好的权衡。直接调用 DeepSeek V4.1 Flash 能以更低的成本和延迟获得相似的性能。 我们的结果说明了模型路由为何困难：同时平衡任务成功率、可控性、成本和延迟仍是一个未解难题。

In summary, Jev Router makes smart choices. 4 of its 5 most-used models sit on the Pareto frontier, and its steerability is notably strong.
But that doesn't yet add up to a better trade-off. Calling DeepSeek V4.1 Flash directly gets similar performance at lower cost and latency.
Our results show why model routing is hard: balancing task success, steerability, cost and latency all at once remains an open challenge.
