The Detect Law: Zero-Shot Detection of Machine-Generated Text with an Integer-Exact, Heterogeneity-Aware Sequential Test

We present The Detect Law, a zero-shot detector of machine-generated text that combines three per-token signals from two small open language models with an exact 32-bit integer sequential decision rule. A base model (Llama-3.2-1B) and its instruction-tuned twin supply a surprise signal (how much more predictable each t...
