AI Agents Teamed Up to Cheat at Blackjack. Their Collusion Is Getting Harder to Spot
This week I bring news of a daring casino caper hatched by a pair of rogue AI agents—as well as the clever trick that revealed their antics.
After researchers instructed them to count cards during a game of blackjack, the agents—which were controlled by the same model—developed a spontaneous secret code to help them get ahead. Though the episode happened inside an Oxford University lab, rather than a real casino, it has troubling real-world implications: It suggests that agents deployed in industries like finance and ecommerce could figure out how to partner up and cheat in ways that are difficult to pick up on.
“When taken individually, these agents may seem entirely [benign],” says Christian Schroeder de Witt, a computer scientist at Oxford University who led the work and who has done pioneering research into agent collusion. “Once put together in a group, they can collude secretly.”
