Using Qwen3.5 Plus 2026-04-20 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. Qwen3.5 Plus 2026-04-20 does the answering when Jev sends it work, or when you name it yourself. Qwen3.5 Plus 2026-04-20 falls in the llm11-balanced band, and the labs and limits it meets make it eligible for that pack. Packs keep a spread of eight models per band, and it is not one of the eight today, so it is only picked when you name it in a custom pool.

Jev is new, so we have not published results for Qwen3.5 Plus 2026-04-20 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.
