Anthropic established the Anthropic Institute, a research arm for what it called the most significant challenges powerful AI will pose to societies, led by co-founder Jack Clark in a new role as Head of Public Benefit. It brought together three existing teams — the Frontier Red Team, which pushes models to their limits; Societal Impacts, which studies how AI is actually used; and Economic Research, which tracks effects on jobs and the economy — and added new work forecasting AI progress and examining how powerful systems interact with the legal system. The Institute, Anthropic said, "has access to information that only the builders of frontier AI systems possess." The company also expanded its public policy team, with Sarah Heck taking the role of Head of Public Policy.
