This research introduces Unsolvable Problem Detection (UPD), a novel method to evaluate if multimodal AI systems truly understand what they claim to know rather than simply guessing.

• Creates unsolvable multiple-choice questions to test if AI models appropriately recognize when they cannot answer
• Establishes a comprehensive benchmark with 3,900+ problems across diverse domains
• Reveals significant gaps between current models' capabilities and human-level understanding
• Demonstrates that even leading models like GPT-4V struggle with recognizing unsolvable problems

For security professionals, this research is crucial as it addresses AI trustworthiness and helps prevent deployment of systems that confidently provide wrong answers, reducing potential risks in high-stakes decisions.
