Cosine Lumen Sovereign UK frontier AI coalition

Cosine announced the formation of an industry coalition to co-design Lumen Sovereign, Britain's first fully sovereign frontier AI model. The coalition includes BAE Systems, Babcock International Group, BT, Era4, HSBC, Leonardo, Lloyds Banking Group, LSEG, NatWest Group, PwC, Telefónica Tech UK&I, Thales UK and The Alan Turing Institute. The project is backed Cosine and the coalition signed a memorandum of understanding to establish a foundational framework for the co-definition of Lumen Sovereign's use-case parameters, rigorous security protocols and necessary governance standards. The agreement supports delivery of a sovereign frontier capability. To deliver Lumen Sovereign Training dedicates approximately one-third of the total compute time to complex software engineering problems. The remaining two-thirds focus on cybersecurity adversarial testing, KYC and AML alert investigations and clinical trial coordination. Lumen Sovereign will be designed for deployment entirely within a customer's own infrastructure, including fully air-gapped environments, with no external data transfer required.
