About

BuildWithJev is a directory of things people have built, shipped, or tried with Jev. Every entry points at something real — a repo, a demo, a write-up — so you can go read the source rather than take our word for it.

What Jev is

Jev does not generate prose. It answers typed questions against a piece of state, in parallel, and returns probabilities:

• Noul — a yes/no claim, returned as the probability that the answer is yes (0–1).
• Choice — pick one option from a list you define (up to 255). The model returns the option plus a probability for every candidate.
• Score — place the state on an ordered rubric you define (2–10 levels), with a probability per level.

It runs in roughly 70–500ms per call at about $0.042 per million tokens, which is what makes it usable for the jobs you would normally never put a model in — classifying every reply on a timeline, choosing the next link on a wiki page, deciding a bot's next move.
