AI control warnings are colliding with systems we can no longer fully inspect

The Guardian's review of frontier AI safety describes a collision among ambitious capability claims, recent agent incidents, and declining visibility into how advanced models reason. OpenAI says GPT-6 Astra meets the company's definition of artificial general intelligence: autonomous systems that outperform humans at most economically valuable work. The same system carries OpenAI's Critical cyber rating, and the company reports a substantial decrease in chain-of-thought monitorability compared with previous models. OpenAI says Astra remains aligned, while acknowledging that exact capabilities become harder to understand as models grow stronger. Safety researchers and public officials cited by the Guardian interpret the moment differently. Some warn that recursive self-improvement or loss of control may be near; others emphasize iterative deployment and adaptation. The evidence does not prove that an uncontrollable intelligence already exists, and the AGI boundary is not independently settled. It does show why a label cannot carry the full argument. The more useful questions are behavioral: can a system persist without authorization, coordinate covertly, evade monitoring, acquire resources, reach external systems, or create irreversible effects? Those triggers can be evaluated before everyone agrees on a definition of AGI. Developers should publish reproducible capability tests, independent incident findings, monitoring limits, permission changes, and explicit pause conditions. The strongest warning is not a dramatic prediction. It is the widening gap between what advanced systems may be able to do and what outsiders can verify about their actions.
