UK and US announce pre-launch AI model evaluations with Big Tech

The UK AI Security Institute (AISI) and the US National Institute of Standards and Technology (NIST) Center for AI Standards and Innovation (CAISI) have announced new partnerships with leading technology companies. 

The AISI announced a partnership with Microsoft to develop and advance methods for evaluating high-risk AI capabilities and the effectiveness of safeguards used to address them. The partnership also includes research into societal resilience, examining how conversational AI systems interact with users in sensitive contexts.

Separately, NIST announced that CAISI has entered into agreements with Google DeepMind, Microsoft and xAI to conduct pre-deployment evaluations and targeted research to advance the state of AI security.

Meanwhile, Politico reports that Anthropic is facing intense criticism from European regulators for withholding its Mythos AI model. The company declined an invitation to a European Parliament hearing scheduled for Wednesday to discuss the model's potential dangers, citing short notice.

Brussels officials are increasingly frustrated that access to Mythos remains limited to a small group of primarily American organisations. A spokesperson for the Commission has indicated that it will use the new enforcement powers of the AI Office, which come into effect in August 2026, to ensure access to the model.
