sovereign British AI capability, so that the UK can be an AI maker and not just a taker. Latest Videos From Watch full video here: BT joins Anthropics Project Glasswing Anthropic launched Project Glasswing in April 2026 with select partners in response to AI-fuelled attacks.

While the frontier model has proven benefits across identifying previously unknown software vulnerabilities (including 16- and a 27-year-old vulnerabilities), generating potential exploit paths and recommending

Because BTs networks underpin large portions of the UKs infrastructure, it means that getting on-board will have far-reached benefits for consumers and businesses. The company boasted that it now prevents four million
cyberattacks across its networks every single day, and thats before it gets on-board with Project Glasswing.

By joining Project Glasswing, BT will strengthen its own cyber security capability to protect our networks, our customers and the wider UK, BT Business CEO Jon James added.

On June 2, Anthropic expanded Mythos access to 150 new organizations across more than 15 countries, which reportedly include Australia, Canada, France, Germany, Italy, Switzerland, the Netherlands, Spain, Belgium, Sweden, India, Japan, New Zealand and South Korea (per The Times of India ).

Participants now span telecoms, energy, healthcare, government and more. At launch, the Claude maker already declared it was in ongoing discussions with US government officials about how Clade Mythos Preview could help its offensive and defensive strategies.

Governments have an essential role to play in helping maintain that lead, and in both assessing and mitigating the national security risks associated with AI models, the company added, expressing an appetite to work with local,
state and federal representatives.

Looking ahead, Anthropic predicts that developers could gain access to similarly capable models within the next six to 12 months with adequate safeguards in place so that they dont amplify the threat theyre designed to tackle.
