KierstonBench benchmark tests language models on 125,000-resident Allentown simulation for record linkage and investigation tasks.

Kierston is a city-scale simulation engine modeling 125,000 residents of Allentown, Pennsylvania, generating daily activities and records. KierstonBench evaluates 32 task families across record linkage, routine reconstruction, incident investigation, and deceptive accounts. Most tested models fail to perform records investigation.

Unconfirmed: Simulation accuracy not independently verified.

Key facts
  • Models 125,000 residents of Allentown, PA
  • Generates daily activities and records
  • 32 task families in benchmark
  • Most models cannot perform records investigation
  • Frontier models solve most tasks and abstain when evidence insufficient

Large language models are candidates for collecting and analyzing records in criminal investigations and mass surveillance. Their capability and accuracy in this work cannot currently be measured. Real deployments lack the ground truth needed to score a model's conclusions, and no benchmark evaluates these capabilities in a simulated environment.
