Samsung’s giant new Texas fab will be dedicated to making Tesla’s next-generation AI6 chip. The strategic importance of this is hard to overstate. Samsung currently makes AI4. TSMC will make AI5, which just finished design, initially in Taiwan and then Arizona.

Musk noted Tesla is working with TSMC to make AI5 chips, which just finished the design. The AI5, a generation that is primarily built for FSD, will initially be made in TSMC’s Taiwan factory and then at its Arizona facility. Samsung already makes the AI4 chip, according to Musk.
