On September 7 local time, Tesla CEO Elon Musk posted on social media that he had just completed an excellent design review with the Tesla AI5 chip design team. He stated that this chip will be an "epic" product, and the subsequent AI6 chip is expected to be the best AI chip to date. Musk added that he believes AI5 could be the best inference chip for models with under 250 billion parameters, offering the lowest silicon cost and the highest performance-per-watt ratio, with AI6 pushing even further.
