Jev case: My favorite piece of the agent stack can't write

Still from the clip posted with this case; watch it in the original post on X.

Described Jev as a bounded-question model that returns yes/no probabilities, picks, or scores in one fast pass for about $0.00002.

The original post

My favorite piece of the agent stack can't write a sentence. Jev (TypeSafe AI, out this month) only answers bounded questions: yes or no with a probability, pick one of N, or score on a scale. No prose. One pass, a few hundred ms, about $0.00002 a check. It runs in three places.

Where this case fits

Filed under agents & workflows. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the agents & workflows page.
