This bill directs federal agencies to build the government's capacity to research, test, and support the development of artificial intelligence while promoting innovation across companies of all sizes. It creates an Artificial Intelligence Safety Institute within the National Institute of Standards and Technology to develop voluntary safety standards, testing methods, and guidelines for AI systems, including tools to detect synthetic content and address cybersecurity risks, and it establishes a related industry consortium to support this work. The bill also sets up AI testbeds run jointly by NIST, the Department of Energy, and the National Science Foundation to evaluate AI systems and foundation models, launches efforts to prioritize public datasets useful for AI training, and creates a prize-based "grand challenges" program to spur research on problems like advanced manufacturing, border security, and next-generation computing. Additionally, it calls for international coalitions to coordinate AI standards with allied nations (explicitly restricting China's participation), requires a Government Accountability Office report on regulatory barriers to AI innovation, and establishes a nonprofit Foundation for Standards and Metrology to support NIST's work, with funding of $500,000 to $1.25 million annually starting in fiscal year 2025. Various provisions include timelines ranging from 90 days to several years for agencies to stand up programs, issue reports, or complete evaluations, and the bill affects federal agencies, AI developers and companies of all sizes, research institutions, and international partners.
