What it is
Jev is TypeSafe AI's System One model: a fast, calibrated classifier. You give it a state and a map of typed questions — yes/no, pick-one, rate-on-a-rubric — and it answers every one in parallel with a probability over the answer space you defined. It never generates text, so the answer is always inside your schema.
Getting started
From the README:
/plugin marketplace add Brainwires/jevwire
/plugin install jev@brainwires-jevwireWhere the decision sits
jevwire calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.
Models it references: Jev.
How active it is
Created 2026-09-17, last pushed 2026-10-30, 25 stars and 6 forks when we read it on 2026-11-02. Everything in this category is weeks old at most, so a stale push date means something different here than it would on a mature project. Check the repository before you depend on it.
Find out what your data actually supports
We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
