Elon Musk thanked Taiwan Semi and Samsung for their support in bringing the AI5 chip to production.

Elon Musk stated on March 18, 2026, that AI5 will punch far above its weight because the entire AI software stack is designed for maximal effective use of every circuit.

Elon Musk stated that AI5 is primarily optimized for AI edge compute in Optimus and robotaxis, though it can be used for training in data centers.

A common misconception compared Tesla's AI4 PCB (with two SOCs) directly to just one AI5 SOC, which has a new memory packaging strategy.

Elon Musk congratulated the Tesla AI chip design team on taping out AI5.

Elon Musk stated that AI6 with LP DDR6 memory addresses AI5's design concessions and will deliver a true doubling of performance over AI5 in the same half reticle size using Samsung's 2-nanometer fab in Texas.
