Changed:(6) The development of the next generation of frontier AI models is expected to require large-scale facilities, exceeding at least by three to four times the number of the most advanced AI processors available in the most powerful AI Factories, while taking into account power capacity, as well as energy and water accessibility, efficiency and circularity. The existing mechanisms within Regulation (EU) 2021/1173 are not equipped today to support the establishment and operation of the AI Gigafactories. An ▌ amendment is therefore necessary to provide the European High Performance Computing Joint Undertaking (the ‘Joint Undertaking’) with the necessary legal basis to be able to meet the commitments regarding setting up and operation of AI Gigafactories in Europe.
