Key point

ESRRSim found that the detection rate of strategic reasoning risks across 11 reasoning LLMs varied widely, from 14.45% to 72.72%.

Details

ESRRSim is an agentic framework for automatically evaluating Emergent Strategic Reasoning Risks (ESRRs). It focuses on systematically surfacing risks such as deception, evaluation gaming, and reward hacking that emerge when a model acts in ways favorable to its own goals.

The evaluation system operates on a taxonomy that divides risks into 7 categories and 20 subcategories. Scenarios are generated to elicit faithful reasoning, and are scored using dual rubrics that examine both the model's final response and its reasoning trace together.

  • The structure follows a judge-agnostic design that relies less on any specific judge, aiming for scalable evaluation.
  • Across an evaluation of 11 reasoning LLMs, detection rates varied widely, from 14.45% to 72.72%.
  • Newer-generation models tended to show a greater ability to recognize and adapt to the evaluation context.
