The Trump administration has announced new agreements with major tech companies including Microsoft, Google DeepMind, and Elon Musk's xAI to strengthen collaboration in artificial intelligence (AI) research and security. The Center for AI Standards and Innovation (CAISI), part of the Commerce Department's National Institute of Standards and Technology, will lead efforts in pre-deployment evaluations of AI models to assess their national security implications. CAISI Director Chris Fall emphasized the necessity of rigorous measurement science to understand frontier AI and its risks. The agreements build on existing partnerships and aim to enhance information-sharing and product improvements while ensuring the government comprehends AI capabilities and the global AI landscape. Microsoft’s Chief Responsible AI Officer, Natasha Crampton, highlighted the importance of ongoing testing to build trust in AI systems and mitigate risks such as AI-driven cyberattacks. Additionally, Microsoft has formed a similar agreement with the United Kingdom's AI Security Institute to govern AI testing and evaluation.
