Can Cosine really build the UK’s first sovereign AI model?

UK startup Cosine has won UK government backing to train Lumen Sovereign, its own frontier AI model, on the Isambard-AI, the UK’s most powerful supercomputer. It will work with partners such as BT, Lloyds Banking, HSBC, BAE Systems, Thales and other major British companies and institutions, to build a frontier AI model designed to operate without dependence on foreign technology or infrastructure. Cosine co-founder Yang Li spoke to Pathfounders’ Editor Mike Butcher about their plans.
