Jev on option order

Jev is a fast decision model: it answers a yes-or-no question about a text instantly and gives no reasons. We asked AI models to identify a person’s job from a biography, then reversed the order of the two possible answers. “Surgeon or physician?” became “Physician or surgeon?” The biography stayed the same. We counted how often the models chose a different job.

This page shows Jev’s results for these tests. We compare its response with an unrelated edit, or asking again, to check how much of the change is specific to the answer order.
