Key Info

OpenRouter launched benchmarks covering three kinds of model routers—blends (Unbiased Pareto, Sakana Fugu), selectors (Auto Router, Jev Router), and switchers (NVIDIA Switchyard)—with leading individual models as comparisons.

Highlights

  • Benchmarks span blends, selectors, and switchers, plus top standalone models for reference
  • Routers aren't always better: model switches rebuild input cache and selection logic adds latency
  • Task complexity is hard to judge from prompts alone
  • The goal is finding the most efficient router/model combo for your workload at a target cost
