Using Solar Mini 4 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. Solar Mini 4 does the answering when Jev sends it work, or when you name it yourself. At list price Solar Mini 4 falls in the llm11-fast band, but no pack routes to it because Upstage is not one of the labs the packs draw from. You can still pin it: pass upstage/solar-mini4 as model and routing steps aside while verification still runs.
Jev is new, so we have not published results for Solar Mini 4 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.
What a request costs
List price arithmetic, the same sum a receipt does. llm11 adds nothing per request; the only fee is on buying credits.
