Musk Reveals Tesla's Dojo Supercomputer Aims for Space AI

During the long weekend, Elon Musk announced that Tesla intends to revive development of Dojo3, the company's previously shelved third-generation AI chip. This time, however, its purpose has shifted; Musk stated Dojo3 will not be used for training terrestrial self-driving models, but will instead be dedicated to "space-based AI compute."

This reversal comes five months after Tesla effectively wound down its Dojo project. The supercomputer team was disbanded following the departure of lead Peter Bannon. Approximately 20 staff members subsequently left to join DensityAI, an AI infrastructure startup founded by former Dojo head Ganesh Venkataramanan and other ex-Tesla employees.

When Dojo was shut down, reports indicated Tesla planned to rely more heavily on partners like Nvidia and AMD for computing power and Samsung for chip manufacturing, moving away from in-house silicon development. Musk's latest remarks signal another strategic pivot.

The billionaire executive and Republican megadonor explained on X that the decision to resurrect Dojo was influenced by the progress of Tesla's internal chip roadmap, noting the AI5 chip design is currently "in good shape."

Tesla's TSMC-made AI5 chip was designed for the company's automated driving systems and Optimus humanoid robots. Last summer, Tesla secured a $16.5 billion deal with Samsung to produce its next-generation AI6 chips, intended for vehicles, robots, and high-performance data center training.

"AI7/Dojo3 will be for space-based AI compute," Musk stated on Sunday, framing the revived initiative as an ambitious long-term venture.

To pursue this goal, Tesla is now reassembling the team it dissolved months ago. Musk used his post to issue a direct call for engineering talent, writing: "If you're interested in working on what will be the highest volume chips in the world, send a note to [email protected] with 3 bullet points on the toughest technical problems you've solved."

The timing of this announcement is significant. At CES 2026, Nvidia introduced Alpamayo, an open-source AI model for autonomous driving that poses a direct challenge to Tesla's FSD software. Musk commented on X that solving the long-tail problem of rare driving edge cases is "super hard," adding, "I honestly hope they succeed."

Musk and other AI leaders have suggested that the future of data centers may be extraterrestrial, as Earth's power grids are already under immense strain. Reports indicate that OpenAI CEO Sam Altman is also exploring the concept of orbital data centers. Musk holds a distinct advantage in this arena through his control of launch vehicle technology via SpaceX.

According to reports, Musk intends to leverage SpaceX's forthcoming IPO to fund a vision of using Starship rockets to deploy a constellation of computing satellites. These satellites would operate in perpetual sunlight, enabling 24/7 solar power generation.

Nevertheless, significant obstacles remain for space-based AI data centers, including the critical challenge of cooling high-power computing hardware in a vacuum. Musk's comments about "space-based AI compute" follow a recognizable pattern: proposing an audacious idea and then mobilizing immense resources to attempt to make it a reality.
