Getting started

From the README:

git clone https://github.com/abhishek085/open-spark-jev.git && cd open-spark-jev
python3 -m venv .venv && . .venv/bin/activate
pip install torch -e ".[infer]"
osj serve --pull spark-s1-4b-v6        # downloads from Hugging Face once, then serves http://127.0.0.1:8400

Where the decision sits

open-spark-jev 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, Alpha, jev-control-core.

How active it is

Created 2026-09-20, last pushed 2026-10-16, 24 stars and 5 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.
