Jev Benchmarking

Reproducible billing and stability measurement of Jev's fan-out behavior across 2,976 requests to jev-1.13-20260917: asking N questions in one call bills the state once, with raw data, exact invoice checks and a batched-versus-single answer comparison.

Head-to-head benchmark of fast typed classifiers, TypeSafe Jev, OpenAI Decisions and Cloudflare Clef, against Claude models on a frozen, labeled corpus of 2,321 cases across 31 tasks, measuring accuracy, calibration, p95/p99 latency and registry-priced cost.

Fixed-wing landing simulator where a human can compete against Jev: four Jev Choice decisions map to aileron, elevator, rudder and throttle commands in JSBSim, run in real time. The benchmark also compares Jev, classical controllers and Codex models on landing score and API cost.
