Verified cascade with Jev (OpenRouter)
External OpenRouter cookbook — check a cheaper draft with Jev before accept or escalate.
What this guide points to
An external OpenRouter cookbook for a verified cascade: draft an answer with a cheaper model, ask Jev whether the retrieved context supports it, then accept or escalate to a stronger model when the check fails.
This page is an unofficial field manual pointer only — verify every path and payload against current TypeSafe docs and OpenRouter’s own cookbook.
What to take away
- Separate cheap generation from judgment; do not ask one chat model to do both silently.
- Define what “pass” means in typed Jev answers before you wire escalation.
- Measure accept vs escalate rates on your traffic; cookbook numbers are not SLAs.
Do not paste long tutorial snippets here; open the source and follow it live.
