Ask a model something it can answer with a number.
Jev is a model made by TypeSafe AI. It answers typed questions about a situation and returns calibrated probabilities: not prose that sounds confident, but a distribution you can threshold. Write a situation, add conditions, and watch what comes back.

Jev is not a chat model, and it will not write you a paragraph.
You give it a situation in plain words, plus the questions you want answered. It gives back a number for each one: how likely a yes is, how a set of choices splits, or where a rating lands.
A number is useful because you can act on it. You can decide to send anything below 0.7 to a person, and move that line later when you learn more. A paragraph that sounds confident gives you nothing to move.
noul on the Yes / no button is Jev's own name for a true or false answer. It is what the API returns.
Whether a number can be trusted is a different question, and it is the one worth asking. The article explains it.
