1/ Anthropic’s Opus 5 model was released publicly today.
@AISecurityInst tested it before release, and you can see their contributions summarised in Opus 5’s system card. Another clear example of the importance of world-leading capabilities the UK has continued to build through AISI.
The speed, robustness, and consistency of AISI’s pre-deployment testing keeps the UK at the forefront of understanding frontier AI capabilities. It has never been more essential than now.
As Britain’s AI Minister, I will continue to champion this ability.
