SAN FRANCISCO: The chip manufacturing joint venture between SpaceX and Tesla called Terafab aims to reach volume production by the third quarter of 2028, Elon Musk said on a SpaceX conference call on Tuesday.

"I put big error bars on this because we don't know if we will actually achieve this or not," Musk said, referring to the timeline.

The timeline is a rough schedule for a project that aims to produce 1 terawatt a year of computing power for AI and robotics, on a schedule Musk himself called "very aggressive."

In the United States, cutting-edge logic factories can take three or more years to build.
