Tesla restarts Dojo3 supercomputer project as AI5 chip stabilizes
Tesla will restart development of Dojo3, the third iteration of its in-house supercomputer project, according to an announcement by Elon Musk on X. The company had previously disbanded the Dojo team to prioritize AI chips operating within Tesla vehicles.
Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3.

Musk stated the project’s resumption comes “now that the AI5 chip design is in good shape.” Dojo’s function involves processing video recordings and other vehicle data to train the neural network for Tesla’s Full Self-Driving software. Last year, Musk indicated that dividing resources between “two quite different AI chip designs” did not make sense, noting that “The Tesla AI5, AI6 and subsequent chips will be excellent for inference and at least pretty good for training.”
The AI chips developed for FSD onboard Tesla vehicles are not optimized for training. Samsung will produce the AI6 chips at its Texas factory under a $16 billion agreement with Tesla.
It doesn’t make sense for Tesla to divide its resources and scale two quite different AI chip designs.
The Tesla AI5, AI6 and subsequent chips will be excellent for inference and at least pretty good for training. All effort is focused on that.

Musk also claimed Dojo3 will be “space-based AI compute.” This concept posits orbital data centers offer benefits like easier access to solar energy and reduced power consumption due to cold temperatures, compared to terrestrial data centers.
