Microsoft, Google, and xAI agreed to give the U.S. Commerce Department pre-release access to frontier AI models so the government can test them for national security and public safety risks before broader deployment. The evaluations will be led by the Center for AI Standards and Innovation (CAISI), housed within NIST, and will examine threats including AI-enabled cyberattacks, biosecurity concerns, chemical-weapons misuse, and other criminal abuse. Officials said the models will be assessed in classified environments, with some testing designed to study systems whose safeguards have been reduced or removed to better understand unmitigated capabilities and failure modes.
The agreements expand earlier voluntary arrangements and align with a broader push for more formal federal oversight of advanced AI, including reported consideration of an executive order establishing government testing protocols before models reach the market. Microsoft said it will also work with CAISI, NIST, and the UK AI Security Institute on adversarial assessment methods, safeguard testing, and frontier safety research, while U.S. officials described the effort as part of a wider strategy to measure unexpected behaviors and misuse pathways in powerful models. Industry groups have largely backed the initiative, framing it as a way to improve trust in commercial AI systems while addressing mounting concern over models that could support offensive cyber operations or other high-risk uses.

5 events from the most recent confirmed update back to the earliest known activity.
The Pentagon signed agreements with seven specialized companies to integrate AI capabilities into classified networks. The move was cited as evidence of deeper adoption of private-sector AI within U.S. defense systems.
CAISI said it had already conducted more than 40 evaluations, including tests on models with guardrails intentionally removed to study unmitigated capabilities. The work was presented as part of its effort to measure frontier-model risks relevant to national security.
The initiative was described as extending commitments made in July 2025 for government access to advanced AI systems to identify unexpected behaviors and national security risks before broader release.
Microsoft said it would work with NIST and CAISI on adversarial assessment methods for unexpected behaviors, misuse pathways, and failure modes, while also partnering with the UK's AI Security Institute on frontier safety and safeguard effectiveness. The company also outlined broader cooperation with international AI institutes and industry groups on evaluation practices.
The U.S. Commerce Department announced that its Center for AI Standards and Innovation would evaluate leading AI models from Google DeepMind, Microsoft, and xAI before deployment to assess security and national security risks. The testing was described as taking place in classified environments and as part of broader best-practice development for commercial AI systems.
