Chips designed by Tesla that are used for robotics and autonomous driving. Deployed in Tesla vehicles in 2019, the Hardware 3 (HW3) was the first self-driving chip. As of 2025, the generation is the Hardware 4 (HW3), also known as AI4. The Hardware 5 or AI5 is expected in 2026, and the AI6 by 2027 or 2028. Samsung is expected to make AI6 chips in its new U.S. foundry, a huge facility in Taylor, Texas. The initial order for $16.5 billion may be only the beginning. The Taylor plant has been a gigantic investment and undertaking for Samsung.
Dojo Chips
Tesla's D1 (Dojo1) chips are used in its Dojo supercomputer for training the AI models with the massive amounts of vision data collected from Tesla vehicles. The D1 is actually 25 chips on a "Dojo tile." The D2 was expected to supersede the D1 but was replaced with Tesla's AI5 and AI6 chips (see
Terafab). See
