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.
