The FSD chip project was led by Pete Bannon. The design team was formed in February 2016. Development was done over the course of 18 months. In August 2017, the chip was released for manufacturing with first silicon coming back in December 2017 fully working. A number of additional modifications were done to the design, requiring [[respinning]]. B0 [[stepping]] was released to manufacturing in April 2018. Full production of B0 started shortly after qualifications in July 2018. In December 2018, Tesla started retrofitting employee cars with the new hardware and software stack. In March 2019, Tesla began volume shipping the FSD chip and computer in their Model S and Model X cars. Production shipment in the Tesla Model 3 started in April 2019. |
