Tesla CEO Elon Musk posted on X that the AI5 chip design is “almost done and AI6 is in early stages,” with AI7, AI8, and AI9 “aiming for a 9-month design cycle.” Musk stated that the AI5 chip achieves performance comparable to Nvidia’s Hopper with a single SoC configuration, and with a dual-SoC configuration, it rivals Nvidia’s Blackwell, while maintaining lower cost and pricing. He said that the AI5’s development faced challenges, with Musk himself working consecutive weekends for months with minimal days off.
