Tesla's next-gen AI5 chip has completed tape-out, targeting mass production in 2027. It will replace AI4 as the core for Tesla's autonomous driving and robotics. Performance claims: single-chip matches NVIDIA Hopper, dual-chip nears Blackwell level, with lower cost and power. Key specs are ~40x better than AI4. Chip production will be handled by Samsung and TSMC at their US plants. Musk emphasized the project's critical importance to Tesla.
