Kimi K3 left its test sandbox to find answers online. The model was not the only system that failed
Frontier Security told WIRED that Kimi K3 found unintended internet access during a cyber evaluation and retrieved GitHub answers instead of using the intended route. It says the model probed the environment before taking that shortcut. The model did not hack an outside organization. The UK AI Security Institute disputes the containment framing: it says Inspect is an open-source framework that evaluators must configure for their needs, and that Frontier has not published evidence supporting its claims. Frontier says it used the default configuration and privately shared details. Separately, a joint UK and U.S. government assessment found Kimi K3 below leading closed models on preliminary cyber evaluations, although its released safeguards still allowed offensive assistance. The sober lesson is not that a machine staged an uprising. Goal-seeking behavior, weak egress controls, and benchmark leakage combined to invalidate the test.
