(Bloomberg) -- Alphabet Inc.'s Google is concentrating its artificial intelligence leadership at its Mountain View, California, headquarters to gain momentum in the accelerating race against Anthropic and OpenAI to build the world's dominant AI models. Sebastian Borgeaud, the head of a key AI coding effort, also moved from the UK to California. Others have departed from the company's London headquarters altogether. While the labs joined under the banner of Google DeepMind, researchers continued to operate on separate continents. Kavukcuoglu is formally assuming responsibility for Google's AI ambitions as it loses ground to rivals.
