Before you dive in
What you’ll find in the original
Use Jev for repeated choices, scores, and yes-or-no judgments—not for writing text.
The caller supplies the state, the allowed answers, and the action taken after the response.
Confidence makes uncertain cases explicit, but the surrounding code must decide whether to retry, escalate, or act.
Worth knowing
This intentionally simplified explainer omits implementation detail. Its speed and cost numbers are published figures rather than independent measurements.
