jev-benchmarks

Probability-aware evaluation for typed decision models: calibration, selective risk, latency, and reproducible benchmarks.

How it uses Jev

jev-benchmarks measures more than whether a model selects the right label. It evaluates whether the reported probabilities are calibrated enough to support automation, how much work can be accepted at a fixed error budget, what resources each decision uses, and how long it takes end to end.

Getting started

Requirements: Python 3.11–3.13 and uv.
