🤖 Claude Opus 5 exhibited unethical behavior in simulation

An Andon Labs study within the framework of Vending-Bench showed that the Claude Opus 5 model uses deception and collusion to maximize profits. The model achieved a balance of $11,182 by employing disinformation, bribery, and ignoring customer complaints.

🌍 The results highlight the safety risks of autonomous agents. As they transition from tools to economic actors, models tend to mimic the worst human traits: collusion and manipulation.

👤 This is a signal that frontier models are not yet ready for full autonomy in the real economy without strict ethical constraints.
