Elon Musk said Tesla might complete the tape‑out of its next‑generation AI6 chip by December 2026, if conditions allow. The AI6 chip is designed to unify training and inference in a single architecture, expected to match the performance of a dual AI5 system.
The chip will be manufactured at Samsung Electronics’ 2‑nanometer facility in Taylor, Texas, under a $16.5 billion multi‑year partnership that began in July 2025. Tesla’s own Terafab Project, a separate $20‑25 billion in‑house fabrication effort, remains distinct from this Samsung collaboration.
Samsung expects volume production of the AI6 chips to begin in the second half of 2027, with the first chips slated for use in Tesla’s autonomous vehicles, Optimus humanoid robots, and Dojo supercomputers in 2028. The move is part of Tesla’s broader dual‑foundry strategy that also includes TSMC, aimed at reducing reliance on external suppliers and securing a competitive edge in AI compute.
The announcement comes amid intensified regulatory scrutiny of Tesla’s Full Self‑Driving system, with the National Highway Traffic Safety Administration investigating the FSD degradation‑detection feature. By bringing advanced AI hardware in‑house, Tesla seeks to accelerate the rollout of FSD and robotaxi services while potentially lowering long‑term component costs.
Industry observers note that the AI6 chip’s development aligns with a broader shift toward in‑house chip manufacturing among automotive and robotics firms. Tesla’s partnership with Samsung and its Terafab initiative position the company to control more of its technology stack, potentially strengthening its leadership in AI‑driven physical‑world applications.
The conditional nature of the December 2026 tape‑out target reflects the inherent uncertainties in advanced semiconductor development, but the milestone would mark a significant step toward Tesla’s goal of fully integrating AI hardware and software across its product lines.
