Arena benchmarks Jev Router: comparable quality to DeepSeek V4.1 Flash but 70% higher median latency
arena · x · 2026-10-08
Arena's evaluation of Jev Router shows smart model selection—4 of its 5 most-used models sit on the Pareto frontier, with strong steerability. But end-to-end it doesn't win: median latency is 6.18s vs 3.64s calling DeepSeek V4.1 Flash (Max) directly, and the gap widens at P90 (30.59s vs 14.26s). Direct DeepSeek calls match performance at lower cost and latency, illustrating why balancing task success, steerability, cost and latency keeps model routing an open challenge.
