What it is
Your model's 0.9 is a vibe. poorjev's 0.9 is a measurement.
Getting started
From the README:
pip install "poorjev[local]"Where the decision sits
poorjev runs its own weights or its own runtime rather than calling a hosted API, so its decisions do not depend on a vendor being up or on a key being funded. The trade is that the model is now yours to keep current.
Models it references: jev, laya, laya.
How active it is
Created 2026-09-19, last pushed 2026-09-21, 11 stars and 0 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.
