International Network for Advanced AI Measurement, Evaluation and Science

International Network for Advanced AI Measurement, Evaluation and Science (NAAIMES) is an international coordination consortium focused on strengthening the science and shared best practices that underpin the measurement and evaluation of advanced AI capabilities. In its current framing, the Network was established in November 2024 and brings together government bodies (including an EU member) from Australia, Canada, the European Union, France, Japan, Kenya, the Republic of Korea, Singapore, the United Kingdom, and the United States to develop internationally recognised approaches for evaluating advanced AI capabilities. The Network’s work emphasizes (1) evaluation approaches that are objective-driven, (2) transparency and reproducibility to support confidence and comparability across evaluations, and (3) open research questions—such as how to use risk models, how evaluators should prioritize with limited resources, what information should be shared vs. withheld, and how to evaluate AI systems rather than only model artifacts. The Network has also been described in public materials as a “refocusing” of the earlier “International Network of AI Safety Institutes” toward measurement and evaluation science, with the UK taking a coordinating role in 2026.
