Earlier this year, Billionaire and X Owner Elon Musk indicated that xAI was gearing up to transform Grok AI into "the most powerful AI by December." The billionaire highlighted that the company was in the process of training the AI tool with “the most powerful AI training cluster in the world,” dubbed Memphis Supercluster. The training cluster features 100,000 liquid-cooled NVIDIA H100 graphic processing units (GPUs) connected with a single RDMA.
However, it was established that xAI was leveraging more than a powerful cluster under the hood to train Grok. X quietly shipped a new update with a new setting that allowed the company to train its chatbot using users' data without authorization as it was enabled by default. While it's possible to disable the setting, the company limited the change to the web version, making it difficult for mobile users to disable it.
