METR (an acronym for Model Evaluation and Threat Research, pronounced "meter"), is a nonprofit research institute that evaluates frontier AI models' capabilities to carry out long-horizon, agentic tasks that some researchers argue could pose catastrophic risks to society. They have worked with leading AI companies to conduct pre-deployment model evaluations and contribute to system cards, including OpenAI's o3, o4-mini, and GPT-4.5, and Anthropic's Claude models.
METR's CEO and founder is Beth Barnes, a former alignment researcher at OpenAI who left in 2022 to form ARC Evals, the evaluation division of Paul Christiano's Alignment Research Center. In December 2023, ARC Evals was then spun off into an independent 501(c)(3) nonprofit and renamed METR.
