At Nvidia's GTC event in Berlin on October 21, CEO Jensen Huang said all telecom operators will eventually provide AI compute and that base stations could evolve into distributed AI networks. He said roughly 100,000 sites could form a distributed data-center network of about 100 gigawatts, and that after nearly eight years of development Nvidia and Nokia had completed a first commercial phone call on T-Mobile's network. Huang also repeated his five-layer "cake" model of AI—energy, chips, infrastructure, models and applications—and said building a 1-gigawatt data center currently costs about $50 billion, as reported by 36Kr and IT之家.
