Cost-Aware Model Routing Without Silent Quality Loss
Route tasks among models using validated task classes, hard constraints, and escalation rather than price alone.
Route tasks among models using validated task classes, hard constraints, and escalation rather than price alone.
简要回答: A cost router should preserve a minimum quality threshold. Use observable task features, start with the cheapest qualified model, verify outputs where possible, and escalate on failure. Keep sensitive or regulated tasks out of routes that violate policy regardless of cost.
实施步骤
- Define task classes and mandatory capabilities.
- Benchmark candidate models per class.
- Build deterministic pre-routing for obvious cases.
- Add bounded escalation based on verification failure.
验证清单
- Track quality, cost, latency, and escalation rate together.
- Test router drift as traffic changes.
- Log provider and model decisions for audit.
常见错误
- Letting a model route based only on its own confidence.
- Optimizing average price while expensive retries rise.
- Sending data to a provider outside the approved boundary.
实际决策
先交付能够通过上述检查的最小设计。记录测试中使用的模型、提示词、工具、数据集与运行时版本，让后续变化可以被比较而不是被猜测。依赖供应商的限制、模型名称、价格或预览功能之前，请重新检查链接文档；这些细节变化往往快于本文的工程原则。
