Jev AI and TypeSafe Explained End to End, Without the Hype
Explains TypeSafe AI's Jev model, showing how it processes input text in a single pass to return typed probabilities across three question primitives. It critiques vendor speed and hallucination marketing claims, detailing confidence calibration and a practical 100-row evaluation methodology.

Jev evaluates state in a single pass returning typed outputs with probability scores across three primitives: Noul, Choice, and Score.
Marketing claims of zero hallucinations only guarantee schema adherence rather than correct decisions, and vendor benchmarks relied on synthetic agreement rather than human review.
Calibration varies significantly across domains, requiring users to empirically validate confidence scores and pin API model versions on their own test data.
Worth knowing
Schema guarantees do not prevent incorrect classifications, and calibration scores on one dataset cannot be assumed to hold across different domains or tasks.
