JevBench: The Benchmark for Typed Decision Models

JevBench measures a very specific kind of AI that stops writing paragraphs and starts giving you a typed answer with a probability score for every option. It is a benchmark for decision models where you hand the system a situation and a rubric, and it returns a clean, structured result without any parsing or fluff. The project is interesting because it ranks these systems on four equal axes: raw intelligence, how well their probabilities match reality, speed, and the actual cost per decision.
