Tesla Unveils AI4 Chip with Full Redundancy for Self-Driving and Optimus

Tesla's new AI4 chip features dual compute modules for instant failover, purpose-built for the safety requirements of autonomous driving and humanoid robotics.

Tesla revealed its AI4 chip on Friday, featuring dual compute modules designed for instant failover — a hardware architecture aimed squarely at the safety demands of Full Self-Driving and the Optimus humanoid robot, as @Tesla_AI announced. The redundancy design means that if one compute module fails, the second takes over without interruption — a critical requirement for systems where a processor crash could mean a car losing control or a robot dropping a payload.
