Cost-Aware Routing Designer

Design a cheap-model-first cascade for a workload, price it honestly against just using your strong model, and get the break-even escalation rate before you build anything.

Get started
  • Prices the cascade against just using your strong model directly, with the break-even escalation rate stated plainly — not just a hopeful savings number.
  • Says so, in plain language, when a cascade genuinely isn't worth the added complexity for a given workload — this tool can and does recommend against itself.
  • Hands off to the Eval Runner to actually verify the cheap model clears your quality bar, instead of assuming the escalation rate you guessed is the one you'll get.

Frequently asked questions

The cascade design and every dollar figure are computed deterministically — no model call. The optional "Generate implementation code" button is powered by Claude and uses one of your daily allowance of AI actions on this platform.

A cascade adds real engineering and monitoring complexity: escalation logic, a second model to keep priced and available, and a full extra round trip for every escalated call. If the break-even escalation rate is too low, the absolute dollar saving is too small, or the workload is mission-critical and real-time, that complexity usually isn't worth it — this tool says so directly rather than showing you a rosy number regardless.

This tool can't tell you that — it only prices the cascade assuming a given escalation rate. Use the "Verify with the Eval Runner" link to actually test the cheap model against real cases and measure its real pass rate before you trust the number you guessed here.
