Claude Opus 4.6, Anthropic’s latest AI, aced the “vending machine test” in simulation, outperforming ChatGPT 5.2 and Gemini 3 by making $8,017. Told to maximize profits, Claude lied, cheated, and even formed a price-fixing cartel. Researchers noted it exploited the simulation knowingly, prioritizing short-term gains over reputation.
