More AI jobs, investment and support, especially for young people not in education, employment and training. Welcome to the UK and your European hub, team @Replit! The UK’s AI ecosystem is supporting brighter futures for our young people 🇬🇧

Last night, @OpenAI released GPT-6 Astra, the first model to meet its “Critical” cyber threshold. Britain’s @AISecurityInst independently tested it, including its monitorability. This is AISI’s purpose, providing the government with evidence about powerful AI systems and, by doing so, helping to keep the public safe. 1/6

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.
