Local, open-source Jev alternative with calibrated confidence.

What it is

poorjev is a local-first System One decision layer for LLM apps. It provides typed decisions (Choice, Score, Noul) with provably calibrated confidence, runs offline on commodity zero-shot NLI models, and requires no API key or waitlist.

How it uses Jev

poorjev reproduces Jev's Choice/Score/Noul interface. It takes a state and typed questions, runs one batched pass through a local zero-shot NLI model, then applies temperature scaling and conformal abstention to return calibrated probabilities and schema-valid answers.

Primitives:choicescorenoul

Technique worth stealing

Temperature scaling and conformal abstention on commodity zero-shot NLI models to achieve calibrated confidence.

Try it

pip install "poorjev[local]" then run examples or poorjev eval --set evalset/tasks.jsonl
