Jev, TypeSafe's System One classifier, as a tool inside Claude Code, Codex, Pi, and OpenCode. Typed labels, yes/no checks, scores, and rankings with calibrated probabilities, in a few hundred milliseconds.

Getting started

From the README:

Where the decision sits

jev-code 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 2026-09-19, last pushed 2026-10-31, 55 stars and 7 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.
