nobody is talking about this and it's insane A Carnegie Mellon University researchers have found a way to use JEV to make your LLM run 24/7 at a lower cost in x350 the LLM only does what needs words. everything else is a typed decision: > which model? Jev routes every task to a tier before a single token is spent > who acts next? one Choice picks the next worker keep or drop? every tool output checked, the noise dropped > risky? anything that sends, pays or deletes gets flagged before it runs > done? Jev checks the goal is actually met, not just "looks finished" > Claude writes research notes and drafts, the only place in the whole folder where text gets generated hard rules: stop after ten actions, never publish anything unapproved > receipts: options offered, chosen id, re-check, fallback, every call logged > the thresholds come straight from my own evals: act only on confident answers, fraud needs 0.95, tuned on dozens of labelled traces and the fees are the whole point > Jev: $0.42 for 10,000 decisions > median: 300 ms per call a whole day of decisions on a frontier model costs dollars. the same day on Jev costs cents you stop babysitting the agent. you read the receipts
