0.8B local model with 2,000 labels beats Jev's frontier API on banking data

A developer benchmarked a 14.3M-parameter decision engine plus an 0.8B reader (vegam) against Jev's live API on real banking77 data. Zero-shot, the local model mostly abstains instead of guessing. After fitting and calibrating on just 2,000 labeled rows — 15 minutes on a single free T4, no fine-tuning, nothing leaves the machine — it beat the frontier API on both accuracy and calibration: route accuracy 0.853 vs 0.756, route ECE 0.029 vs 0.100; dispute accuracy 0.892 vs 0.846. Takeaway: frontier models generalize, calibrated local models adapt — with full data privacy. Reproducible via pip install vegaml.
