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 for developing driverless-vehicle technology.

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.

The move to unwind the AI division comes as 20 Dojo employees have left for DensityAI, a new startup led by its former head, Ganesh Venkataramanan.
