Using Nemotron 3 Ultra 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. Nemotron 3 Ultra does the answering when Jev sends it work, or when you name it yourself. At list price Nemotron 3 Ultra falls in the llm11-balanced band, but no pack routes to it because NVIDIA is not one of the labs the packs draw from. You can still pin it: pass nvidia/nemotron-3-ultra-550b-a55b as model and routing steps aside while verification still runs.

Jev is new, so we have not published results for Nemotron 3 Ultra 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.

Call it

Same OpenAI request shape. Naming the model pins it, so nothing is routed, and the answer is still checked.

res = client.chat.completions.create(
