The US government has announced new regulations that will restrict the export of artificial intelligence (AI) chips and technology to most countries, while allowing unlimited access to US AI technology for its closest allies. The rules aim to maintain US dominance in AI and keep advanced computing power within the US and its allies, while limiting China's access. The regulations will cap the number of AI chips that can be exported and maintain a block on exports to China, Russia, Iran, and North Korea. The new rules also place limits on advanced graphics processing units (GPUs) used to power data centers for training AI models.
