Dec 5 (Reuters) - NEXTDC ( NXDCF ) said on Friday it has inked a memorandum of understanding with ChatGPT maker OpenAI to jointly plan, develop and operate a hyperscale AI campus and graphics processing unit, or GPU, supercluster at its S7 site in Sydney.

The Queensland-based data centre operator's S7 site at Eastern Creek in Sydney was acquired last October for nearly A$353 million ($233.37 million) and offers 550 megawatts (MW) of potential capacity.

The AI boom is spurring a global race for data centre capacity, with hyperscale builds luring tech giants and investors, and operators like NEXTDC ( NXDCF ) riding the wave, lifting its contracted utilisation by 71 MW to 316 MW after recent wins.

The Australian Financial Review reported on the deal on Thursday.
