Jev 1.13

A closed text-input model served through TypeSafe's own API under the pinned ID jev-1.13.0 and listed on Vercel AI Gateway; it answers typed questions about supplied text with a selected option, a score, or a yes-probability instead of free-form prose, and no weights are published. The Atlas's own Hacker News signals routine calls this model, so this review rests on published documentation and terms only.
