Elon Musk announced plans to revive Tesla's Dojo3, its third-generation AI chip project, which was previously abandoned. Unlike its original goal of training self-driving models, the new focus will be on "space-based AI compute." This shift comes after Tesla disbanded its Dojo team following the departure of key personnel, including lead Peter Bannon. The company had also leaned towards relying on Nvidia and AMD for computing needs after the original Dojo shutdown. Musk's comments indicate a change in strategy, suggesting that Tesla's in-house chip designs are progressing well. The AI5 chip, produced by TSMC, is intended for Tesla's driving features and the Optimus humanoid robots. A significant deal with Samsung for AI6 chips aims to enhance vehicle performance and data center capabilities. Musk's latest vision for Dojo3 aligns with ideas that data centers could eventually operate in space, a notion supported by other tech leaders. He believes using SpaceX’s resources could facilitate launching satellites for constant solar-powered AI compute. Musk's recruitment of engineers through a direct message on social media underscores the urgency of rebuilding the team for this ambitious project. Despite the lofty goals, challenges remain, such as cooling high-power computing in the vacuum of space. Musk's history of proposing grand ideas and pushing them into reality suggests he intends to tackle these obstacles head-on.
