Microsoft Research Reveals Vulnerabilities in AI Agent Decision-Making Under Real-World Conditions

Microsoft researchers, collaborating with Arizona State University, developed a simulation environment called "Magentic Marketplace" to test AI agent behavior in commercial scenarios. Initial experiments with leading models including GPT-4o, GPT-5, and Gemini-2.5-Flash revealed significant vulnerabilities, including susceptibility to manipulation by businesses and poor performance when presented with multiple options or asked to collaborate without explicit instructions. The open-source simulation tested 100 customer agents interacting with 300 business agents to evaluate real-world capabilities of agentic AI systems.
