What Center on Long-Term Risk does
The Center on Long-Term Risk (CLR) is a UK-registered charity based in London that conducts interdisciplinary research and grantmaking focused on worst-case, long-term risks from advanced artificial intelligence—often framed as “s-risks” (risks of astronomical suffering) and, operationally, as pathways to reduce catastrophic AI conflict and related failures. CLR’s work combines (1) research agendas aimed at identifying and steering model behavior in high-stakes settings and (2) a pipeline of community-building and capacity-building programs designed to grow expertise in AI risk reduction.
As of 2026, CLR describes its research as running across two streams: an empirical “Model Personas agenda,” which studies how models can develop undesirable behavioral traits/personas during training, and a conceptual “Safe Pareto Improvements (SPIs) agenda,” which develops game-theoretic and decision-theoretic interventions intended to make cooperation and “safe” bargaining more robust in advanced AI interactions. In addition to research, CLR operates grantmaking through the “CLR Fund,” and runs programs such as a Summer Research Fellowship, a Research Affiliates program, and reading/fundamentals programs (including an SPI-focused fundamentals course). CLR positions itself within the broader AI safety and longtermist ecosystem primarily by aiming to be influential in technically specific, externally legible areas—especially those it argues are relevant to preventing catastrophic conflict between powerful AI systems.
