Import AI 446: Nuclear LLMs; China’s big AI benchmark; measurement and AI policy

The newsletter highlights three significant developments in AI research and policy. First, it discusses emerging work on "nuclear LLMs"—large language models with particularly powerful or potentially dangerous capabilities. Second, it covers China's development of a major AI benchmark, indicating intensifying competition in AI evaluation standards and capability measurement. Third, the piece emphasizes that measurement of AI systems is fundamental to effective AI policy, with researcher Jacob Steinhardt suggesting that improving how we measure AI performance and risks could be a straightforward yet impactful policy intervention.
