What is Jev?

Jev is TypeSafe’s fast model for bounded decisions. A YES/NO-style question comes back as a probability. Jev can also score or choose among a small set of options. People use it when a decision has to be cheap and quick enough to run often, and a person, another model, or a rule can take the cases that should not be automatic.

JevBench helps you work through one of those decisions on examples you understand. You label what YES means, see where Jev differs, improve the question, and check again.

JevBench is independent. It is not TypeSafe’s documentation and it is not affiliated with TypeSafe. For the model itself, start at thejevai.com.
