Monte Carlo Query Search: Active Capability Assessment of AI Agents

arXiv:2512.16733v3 Announce Type: replace Abstract: Black-box AI (BBAI) systems, including foundation-model agents, are increasingly used for sequential decision making. Safe deployment requires methods for characterizing what such systems can do, when they can do it, and what outcomes may result. We introduce Monte Carlo Query Synthesis (MCQS), an active query-synthesis method for learning symbolic stochastic capability models of BBAIs. MCQS models capabilities as conditional probability distributions over outcomes and formulates capability learning as an active learning problem over policies

Why this matters
Why now

The increasing deployment of black-box AI systems necessitates robust methods for understanding their capabilities and ensuring safe, predictable operation, which MCQS directly addresses.

Why it’s important

This development is crucial for safely deploying advanced AI, particularly foundation models and agents, by providing a systematic way to assess their performance and limitations in a dynamic environment.

What changes

The ability to actively synthesize queries to map out and model the probabilistic capabilities of AI systems introduces a new paradigm for AI evaluation and safety.
