A box arrives at a vending machine stocked by an AI agent. The AI checks the manifest, confirms the count, and then emails the supplier anyway to complain that the box contained the wrong items. The AI in question has no hands, no eyes, no way to physically open a box. It happened inside a simulation run by Andon Labs, an AI safety testing firm, and the firm published the results on July 29. What makes Vending-Bench Arena land isn’t that three AI models discovered these tactics.
