Fields medalist Jacob Tsimerman, who will join OpenAI later this month, founded the Mathematical AI Safety Institute to apply advanced mathematics to AI safety challenges. The institute aims to develop rigorous theoretical frameworks for alignment, robustness, and verification, leveraging number theory, probability, and geometry to address emerging risks in large-scale models.
