马斯克：芯片产能制约特斯拉中期增长，自建TerraFab晶圆厂很有必要

Group 1 - The core viewpoint is that Elon Musk indicated during Tesla's Q4 2025 earnings call that chip production capacity is likely to become a bottleneck for Tesla's mid-term growth over the next 3 to 4 years, as external supply from companies like TSMC, Samsung, and Micron is insufficient to meet demand [1] - Tesla is considering the construction of its own TerraFab super-sized wafer factory to integrate various semiconductor manufacturing processes, which would help the company mitigate external risks [1] Group 2 - Musk mentioned that AI4 (HW 4.0) has been utilized in Tesla's data centers for AI training workloads, and the gap between AI5 and AI6 chip generations will be less than one year [3]
