Tesla Inc. is disbanding its Dojo team and its leader will leave the company, according to people familiar with the matter, upending the automaker’s effort to build an in-house supercomputer

The disbanding of Tesla’s Dojo efforts follows the departure of around 20 workers, who left the automaker to start their own AI company dubbed DensityAI focused on data center services for industries.

Tesla is dissolving the team that was developing its Dojo supercomputer, according to Bloomberg. The change, which reportedly includes the departure of Dojo head Peter Bannon, marks a notable shift away from using in-house technology to train the AI models powering Tesla’s self-driving features and its Optimus humanoid robot.
