Software at Tesla - A peek from the outside
summary
Tesla uses date-week versioning and pushes updates roughly every two weeks (one car got 24 updates last year), can patch every controller since 2012, and runs feature flags across ~5 million cars. Factory assembly runs self-tests per component, a 1,000-person data team plus automated labeling and simulation produce ~10,000 targeted clips/week, and training pipelines perform over a million validation runs on custom-managed infrastructure, driving a reported 4x efficiency in internal processes.
