AMI Labs, cofounded by Yann LeCun after leaving Meta as chief AI scientist, raised $1.03 billion at a $3.5 billion pre-money valuation to develop world models—AI systems learning from physical reality to overcome LLM limitations like hallucinations. The Paris-based startup, with offices in New York, Montreal and Singapore, drew investors including Cathay Innovation, Greycroft, Bezos Expeditions, Nvidia and angels such as Mark Cuban.
London-based Nscale, pivotal to UK AI strategy, raised $2 billion at $14.6 billion valuation as ex-Meta COO Sheryl Sandberg and Meta global affairs chief Nick Clegg joined its board. A Guardian investigation questions the government's multibillion AI push, revealing Nscale's pledged Essex supercomputer—touted as three times more powerful than top US machines—remains a scaffolding yard with construction pending despite 2025 deadlines.
