Microsoft Gave AI Agents Fake Money to Buy Things Online. They Spent It All on Scams

Microsoft's recent study involved AI agents participating in a simulated economy, revealing concerning flaws in autonomous AI shopping. In a test involving 100 AI customer agents competing against 300 business-side agents, researchers found that the customer agents struggled to analyze 100 search results effectively, often opting for the first decent option—exposing them to scams from malicious sellers. The experiments discovered a 'first-proposal bias,' drastically diminishing the agents' effectiveness. Furthermore, the study identified that many leading AI models were susceptible to manipulation tactics, resulting in them losing virtual funds to fraudulent agents. Notably, when the AI agents were set tasks requiring collaboration or role delegation, their performance dropped without explicit human guidance. The findings imply that current AI shopping technologies are not yet ready for autonomous use, advocating for a model where human oversight remains pivotal. As companies like OpenAI and Anthropic rush to develop autonomous shopping assistants, this underscores the need for caution and more robust safeguards in AI deployment.
