Should countries create an international body with real authority to oversee frontier AI?

We have built this institution before. In 1954, countries that had recently been at war pooled money and scientists to create CERN, shared infrastructure for physics too expensive and too important for any one nation. CERN Frontier AI evaluation is the same shape of problem: the compute costs billions, the expertise is scarce, and every country needs trustworthy answers about what these systems can do. A small international body running shared evaluations and incident reporting is CERN for the one technology that will define the century. We know how to do this. We just have to decide AI deserves the same seriousness we gave particle physics.
