🇺🇸 English 🇨🇳 简体中文 🎮 Results & Demos ⚡ Quickstart 💻 Run locally 🤗 Models 📊 Benchmarks 📚 Docs
The homepage listed on the repository, simplejev.github.io, puts it like this: Train and deploy System 1 decision models with JevAny. Bring a model, define the options, and get a choice with probabilities. Open source, from robotics to software.
Where the decision sits
JevAny 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.

How active it is
Created 2026-09-22, last pushed 2026-10-29, 129 stars and 14 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.
