Using Palmyra X5 with Jev
Jev is TypeSafe AI's System One model. It reads each request first and decides which model in your pool answers, with a calibrated confidence on that call. Palmyra X5 does the answering when Jev sends it work, or when you name it yourself. At list price Palmyra X5 falls in the llm11-balanced band, but no pack routes to it because it does not advertise structured output, which the verification checks rely on. You can still pin it: pass writer/palmyra-x5 as model and routing steps aside while verification still runs.
Jev is new, so we have not published results for Palmyra X5 with and without it, and this page does not invent any. Every response comes with a receipt that names the model that answered and what it cost against your most expensive model, so you can measure the pairing on your own traffic.

List price arithmetic, the same sum a receipt does. llm11 adds nothing per request; the only fee is on buying credits.
