SAN FRANCISCO (Reuters) -Crusoe CEO Chase Lochmiller said on Thursday the artificial intelligence data center builder planned to purchase roughly $400 million worth of AI chips from Advanced Micro Devices to add to its portfolio of computing power. The cloud computing startup is aiming to build a data center – or cluster – to house the AMD AI chips in the U.S. and will rent them to customers for building AI models and running applications. Crusoe’s data centers are purpose-built to house AI chips, which it says allows it to offer superior performance compared with older designs.
