Google, Microsoft and xAI to Undergo US Government AI Safety Evaluations for Cyber and Biosecurity Risks

The US Centre for AI Standards and Innovation will evaluate models from Google, Microsoft and xAI for cybersecurity, biosecurity and chemical weapons-related risks before they are released to the public, Euronews reported on 08/05/2026. Tech firms Google, Microsoft and xAI have agreed to have the US Department of Commerce examine their models through CAISI.

The evaluations will cover testing, collaborative research and best practice development related to commercial AI systems.

CAISI will also evaluate demonstrable risks associated with AI systems such as cybersecurity, biosecurity and chemical weapons risks. CAISI has already conducted 40 evaluations of other models, including some state-of-the-art models that remain unreleased. OpenAI and Anthropic signed agreements for these evaluations in 2024 under former President Joe Biden.

CAISI said existing agreements had been renegotiated. "Independent, rigorous measurement science is essential to understanding frontier AI and its national security implications," said CAISI Director Chris Fall in a statement. " Microsoft said in a statement that the CAISI evaluations will help it stay ahead of risks such as AI cyber attacks for its AI model Copilot.

5 ahead of its public release this week to support national security testing and evaluations. 5-Cyber, a specific model that will strengthen cyber defence capabilities and which is only available for a limited group of first users. OpenAI is involved in developing a responsible deployment strategy for the cybersecurity model, including a playbook to distribute these models throughout the public service.

The announcement comes after President Trump released his AI National Policy Framework in March. The framework says the United States will remove barriers to innovation and accelerate the deployment of AI across various sectors. It also states that Congress will not create any new federal rulemaking bodies to regulate AI.

The shift reflects a departure from earlier approaches. Trump's framework instead directs existing regulatory bodies and experts in specific domains to examine the models. CAISI's work on frontier systems now operates within that policy structure.
