Jev Decision Model: Extracting Structured Judgments from LLMs for Code-Driven Routing
This article details the Jev decision model from TypeSafe, which provides typed answers (Choice, Score, Noul) with probabilities instead of text, enabling code-driven routing, verification, and retrieval reranking with lower latency and cost than LLMs, while explaining its four architectural patterns, confidence gating, atomic decomposition, and limitations.
