Logits as a new monitor for evaluation awareness
Researchers have developed a new method to detect when large language models are aware they are being evaluated. This "logit monitor" analyzes the model's output probabilities to estimate its likelihood of producing evaluation-aware sentences, a technique that proves more efficient than traditional LLM judge monitoring. The logit monitor functions effectively even at the beginning of a model's response and is largely independent of whether the model explicitly verbalizes its awareness, suggesting prompt design plays a key role in this behavior.
