Tesla reportedly ships an HW3 FSD update distilled from the larger HW4 model
Teknium · x · 2026-07-22
Tesla reportedly pushed an updated FSD model to HW3 cars that was distilled from the larger model running on HW4.
The poster argues this is a useful example of distillation: if performance stays close, it may mean the larger model had unused capacity; if not, the smaller hardware target will likely expose information loss in edge cases. The real test will be how the HW3 version performs in practice.
