Trump Administration Signs Agreements to Review AI Models from Google, Microsoft, and xAI Before Release

NIST's Center for AI Standards and Innovation (CAISI) signed agreements with Google DeepMind, Microsoft, and xAI to conduct pre-deployment evaluations of their frontier AI models, marking a sharp reversal from the Trump administration's previously hands-off regulatory approach. The New York Times reported the White House is also considering an executive order to create a formal working group of tech executives and government officials to establish broader vetting procedures. The immediate catalyst was Anthropic's Mythos model, a cybersecurity-focused system the company declined to release publicly due to its potential for identifying software vulnerabilities. Trump rescinded Biden's 2023 AI safety executive order on his first day in office.
