AX-Ray Reveals Causal Leakage Defects in Two Public AI Models

VIDRAFT’s AX-Ray project presents a model-evaluation method that goes beyond performance scores after identifying and repeatedly reproducing defects it described as causal leakage in the Zyphra/Zamba2-1.2B and nvidia/Nemotron-H-8B-Base-8K models. The framework places these cases among defects that prevent deployment, distinguishing them from serving-path or API issues.
