Musk: Tesla restarting Dojo supercomputer effort as “AI5 chip design is in good shape”
Tesla CEO Elon Musk said in a post on X over the weekend that the company plans to restart work on its Dojo supercomputer, dubbed Dojo3, saying that the AI5 chip the company had been developing is in “good shape.”
The Dojo supercomputer trains Tesla’s AI models, including the one behind its all-important Full Self-Driving tech. The company stopped work on Dojo in August. “It doesn’t make sense for Tesla to divide its resources and scale two quite different AI chip designs,” Musk said at the time. “The Tesla AI5, AI6 and subsequent chips will be excellent for inference and at least pretty good for training.”
“Pretty good” appears to be good enough.
Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3.

In the interim, Tesla relied more on companies like Nvidia and Advanced Micro Devices for AI training. Restarting Dojo suggests Tesla plans to bring at least some AI training back in-house.
Musk also runs AI company xAI, which has its own supercomputer and a substantial business relationship with Tesla. A plurality of Tesla shareholders recently voted in favor of investing in Musk’s AI company, but the board declined to approve the measure because of a large number of abstentions.
