reflex

A small open decision model: state + typed questions -> calibrated probabilities. A Jev / System One re-creation on Qwen3.5.

How it uses Jev

It is an open re-creation of Jev, the "System One" model TypeSafe released in September 2026, built on top of a normal open-weights model (Qwen3.5-4B by default).
