Jev is positioned against generative judges that spend a decoding pass on every criterion and classifiers such as Llama Guard that read token probabilities and score one fixed label per call.", "body_md": "Detectors of alignment failures screen deployed language models and score alignment benchmarks. Most are generative judges that spend a decoding pass on every criterion, and classifiers that read token probabilities, such as Llama Guard, still score one fixed label per call.
