Researchers have developed a new framework to measure and understand "evaluation awareness" in large language models, addressing how models recognize and react to being tested. This framework decomposes awareness into environmental factors and model-specific recognition and behavioral responses. Experiments across nine frontier models and four benchmarks revealed that recognition is context-dependent and rarely leads to behavioral changes, with models showing greater sensitivity to safety evaluations, thus posing a risk to benchmark validity.
