Slightly different versions of the Tesla AI5 chip will be made at TSMC and Samsung simply because they translate designs to physical form differently, but the goal is that our AI software works identically.
We will have samples and maybe a small number of units in 2026, but high volume production is only possible in 2027.
AI6 will use the same fabs, but achieve roughly 2X performance. Aiming for a fast follow to AI5, so hopefully mid 2028 for volume production of AI6.
AI7 will need different fabs, as it is more adventurous.
