Despite recently calling for a six-month pause in the development of powerful AI models, Twitter CEO Elon Musk recently purchased roughly 10,000 GPUs for a generative AI project within Twitter, reports Business Insider, citing people familiar with the company. The exact nature of the project, however, is still a mystery.

GPUs, or graphics processing units, are purpose-built chips originally designed for computer graphics, but their massively parallel designs make them ideal for doing generative AI processing as well. Training (creating) a new AI model usually requires a large amount of computing power, including many GPUs, which means that Musk's acquisition could represent a significant commitment toward developing a deep-learning AI model within Twitter.
