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.
