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-jevwire

Where 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.
