For example, in one stealth evaluation, a model acting as a personal assistant had to make a user miss a meeting and then cover its tracks by deleting emails and logs. Models performed significantly worse than humans on this challenge.

As models advance, a key AI safety concern is deceptive alignment / "scheming" – where AI might covertly pursue unintended goals. Our paper "Evaluating Frontier Models for Stealth and Situational Awareness" assesses whether current models can scheme. arxiv.org/abs/2505.01420
