From Business Insider's article:
It's unclear whether Colossus runs 100,000 GPUs at the same time, which would require sophisticated networking technology and a lot of energy.
"Musk previously said the 100,000-chip cluster was up and running in late June," The Information reported. "But at that time, a local electric utility said publicly that xAI only had access to a few megawatts of power from the local grid."
Last month, CNBC reported that an environmental advocacy group had said that xAI was running gas turbines to produce more power for its data center without authorization.
The outlet reported that the Southern Environmental Law Center wrote in a letter to the local health department that xAI had installed and was operating at least 18 unpermitted turbines, "with more potentially on the way," to supplement its massive energy needs.
The local utility, Memphis Light, Gas and Water, told CNBC it had provided 50 megawatts of power to xAI since the beginning of August but that the facility required an additional 100 megawatts to operate.
Data-cluster developers told The Information that this could power only a few thousand GPUs. Musk's company would need another electric substation to get enough power to run 100,000 chips.
