特斯拉计划重启Dojo3，转向太空AI计算

Tesla CEO Elon Musk said the company plans to restart development of Dojo3, its previously shelved third-generation artificial intelligence chip, with a new and narrower objective. Instead of supporting terrestrial self-driving training workloads, Musk said Dojo3 will be designed for “space-based AI compute.” The comment marks a notable shift for a project that was once positioned as a cornerstone of Tesla’s in-house AI ambitions on Earth. Dojo was originally conceived to reduce reliance on third- party chips for training neural networks used in autonomous driving. Dojo3, however, was paused as Tesla prioritized near-term compute needs using Nvidia hardware. The decision to revive the project for space use suggests a reassessment of where custom silicon could offer long-term advantages. …
