πͺ We have unveiled Jev's Doors (Jeven Doors). It is a deduction game where you guess the "correct answer" that the AI has decided in its mind within 7 yes/no questions. The AI that answers is TypeSafe's "Jev." It is a model that does not generate sentences at all, and only returns "probabilities" for typed questions about the transmitted state. This property

Engagement when collected
Numbers are a snapshot taken from X when the case was added to the library (schema v1, collected 2026-09-19); they will not match today.
Where this case fits
Filed under general Jev builds. In the pattern Jev is built for, the model answers a bounded question per step β and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Browse the full case library for the work it sits next to.
