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

Ran the same eBay end-to-end test flow through Jev and two chat models, reporting median run time and cost per completed run.

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 coding & developer tools. 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 coding & developer tools page.
