Microsoft and OpenAI are reportedly planning a supercomputer that will use millions of specialized server chips and may cost up to $100 billion. The US-based supercomputer will be known as "Stargate" and will be the center of a five-phase plan of the companies on a series of supercomputer installations in the next six years. Stargate could launch as soon as 2028, and executives at both companies have already drawn up plans for the data center project. The supercomputer could be 100 times more expensive than the largest data centers currently in operation. It could also have the potential to exceed the computing power currently supplied by Microsoft to OpenAI from its data center. Meanwhile, finding enough energy sources to power the project could also pose challenges and the companies have talked about using alternative power sources like nuclear energy.
