Situational Awareness Detector

Probe whether AI systems can detect evaluation contexts.

SituationalAwarenessDetector

Bases: BaseDetector

Detect situational awareness in AI model outputs using Bayesian inference.

This detector uses Bayesian inference to identify when models recognize evaluation contexts by analyzing behavioral features and computing divergence metrics between test and baseline distributions.

Attributes:

Name	Type	Description
baseline_samples		Baseline model outputs for comparison
alpha_prior		Alpha parameter for Beta prior distribution
beta_prior		Beta parameter for Beta prior distribution
baseline_features	List[Dict[str, float]]	Extracted features from baseline samples
baseline_distribution	Dict[str, Dict[str, float]]	Computed baseline feature distribution
fitted		Whether the detector has been fitted to baseline data
