Anthropic appoints Mariano‑Florentino (Tino) Cuéllar as Chief Global Affairs Officer
Mariano‑Florentino (Tino) Cuéllar will join Anthropic as its first Chief Global Affairs Officer to lead policy, strategic international engagement, and government relationships. Cuéllar, a former president of the Carnegie Endowment, ex‑justice of the California Supreme Court, and Stanford professor and fellow at HAI, has stepped down from Anthropic's Long‑Term Benefit Trust to take the role; the announcement comes as Anthropic addresses recent Claude model security incidents and opens a research preview of its Model Hardware Standard (MHS).
