Russian-born computer scientist, co-founder and chief scientist of OpenAI, shaping modern AI research
This week has seen major moves in AI infrastructure financing and buildouts. SpaceX has released renderings for Terafab, a more-than-100-million-square-foot semiconductor factory it plans in Texas that it values at at least $16.8bn for the initial phase. Separately, Nvidia has been reported to be negotiating a $250bn guarantee to back OpenAI’s proposed 10-gigawatt Ohio data‑centre lease and construction debt.
A high-profile AI-focused hedge fund has unwinded after massive leverage and a momentum crash. Citadel has stepped in to acquire many of its publicly traded holdings while the fund holds private investments, including Anthropic. Regulators and investors watch for how this affects AI infrastructure bets and market risk.
Google has reorganised its AI leadership: Demis Hassabis has stepped back from day-to-day running of DeepMind to become its chair and Alphabet chief scientist, and Koray Kavukcuoglu has been promoted to senior vice-president to run Google DeepMind. Several senior engineers, including Jeff Dean and Sanjay Ghemawat, have left to launch a new startup; Alphabet shares have fallen.
