Anthropic announced the appointment of Mariano-Florentino 'Tino' Cuéllar as a new member of the Long-Term Benefit Trust, the independent body that supports the company's public benefit mission. Why does this matter to you? Because the Trust isn't just symbolic: it helps decide who sits on Anthropic's board and how the company balances innovation with social responsibility.
Who is Mariano-Florentino 'Tino' Cuéllar
What does he bring to the table? A mix you don't see every day: public service, academia, and civil-society work. He served as a justice on the California Supreme Court, led Stanford's Freeman Spogli Institute, and currently chairs the Carnegie Endowment for International Peace. He also announced he'll leave Carnegie in July 2026 to return to Stanford to lead the Center for Advanced Study in the Behavioral Sciences and the Knight-Hennessy Scholars Program.
His background includes work across three U.S. presidential administrations and the chairmanship of the William & Flora Hewlett Foundation board. He grew up on the U.S.–Mexico border, which gave him a broad perspective on migration, criminal justice, public health, and regulatory reform. In AI, he co-led California's Working Group on AI Frontier Models with Fei-Fei Li and has served on National Academy of Sciences committees about the social and ethical implications of computing.
