Is Jev a scam? What TypeSafe AI’s System One model is, and what happened when we ran it

Jev is a real, hosted, closed model that returns typed decisions with a probability vector. Its 193x / 445x marketing numbers are unproven by anyone, including TypeSafe. We ran jev-1.13.0 on Swiss bookkeeping data: accurate and calibrated on 54 real accounts, confidently wrong on a 10-item cohort.
