SPIA in DC partnered with CITP faculty to convene the first two in a series of “Princeton AI Dialogues: Expert Briefings” on Capitol Hill. One with the Senate AI caucus, and a second with the House AI Caucus. Together, the two sessions drew more than 50 participants from Republican and Democratic congressional offices and committees. Professors Arvind Narayanan and Peter Henderson, together with PhD candidate Sayash Kapoor spoke to a wide range of topical issues regarding AI development and governance—open vs closed models, safety and catastrophic risk management, testing/validation/red-teaming, cybersecurity, copyright, deepfakes, watermarking and provenance, potential impacts on labor, hiring, judicial processes, and children.
