A new benchmark called Physical-Engineering's Last Exam (PLE) developed by Google and Mercor reveals that current AI agents struggle with complex engineering tasks, achieving only 41.3% of designs that meet all safety and feasibility requirements. While agents can satisfy most individual constraints, they falter when multiple requirements interact or when long-term state consistency is needed across numerous documents and revisions. The research highlights the need for AI systems that can manage design states, understand interdependencies, and perform robust validation, suggesting that future engineering agents will require sophisticated verification mechanisms as core infrastructure.
