The world's first GW-class superb cluster, Colossus 2, is fully operational

colossus 2 of xAI officially went online, becoming the first global overcalculable cluster of 1 GW power, to be upgraded to 1.5 GW in April, with a final installed capacity of 2 GW; when completed, the cluster will contain 555,000 GPUs, far above Meta and Microsoft, all exclusive to Grok, and is expected to provide training in Grok 5, which supports 6 trillion parameters; the surge in the use of power in the data centre has led to the possibility that 67 million inhabitants of the PJM grid area in the United States may face a rotational power outage and XAI has deployed 168 TeslaMegapack energy systems to mitigate the impact。
