The move was announced this week by CEO Allison Kirkby, as part of her opening keynote at the UK Government's AI Adoption Summit, an event aimed to accelerate AI usage across the UK economy.
Project Glasswing will allow BT controlled access to the frontier AI model 'Claude Mythos Preview', in order to help strengthen cybersecurity for its networks and customers against the latest AI threats.
It comes after Ofcom penned an Open Letter to telecoms providers in April 2026, calling on companies to 'assess the security risks arising from frontier AI models and take appropriate mitigating action'.
In her address, Kirkby outlined the critical role of connectivity in ensuring the UK can seize the growth potential of AI, saying: "AI only works at scale when it is underpinned by future-ready networks that are secure, resilient, safe".
"(BT are) committed to working with Government to support the further development and deployment of sovereign British AI capability, so that the UK can be an AI maker and not just a taker.”
BT has stated in the past that their systems currently prevent 4 million cyber-attacks across their networks every day, underlining the scale of the threat and the importance of staying ahead of it.
Jon James, CEO of BT Business, added: “AI is changing cyber security fast, and businesses need trusted partners who can help them stay one step ahead. By joining Project Glasswing, BT will strengthen its own cyber security capability to protect our networks, our customers and the wider UK.”
