FSD 12.5.1 goes wide, HW3 rollout in August

Tesla has officially announced that the FSD 12.5.1 is now getting a wide release for customers in the US and brings several new improvements.

Last week, the EV maker released FSD 12.5 for subscribers and Tesla owners. Early impressions reveal polished smoothness and fixed previous bugs. However, some issues remain in the build that need to be resolved.

Some major changes are also pending for the upcoming updates including the more natural lane change decision, vision-only driver monitoring with sunglasses, end-to-end on highway, and FSD on Cybertruck.

Soon after the 12.5 rollout, Tesla staged 12.5.1 in the same week. It’s going wide and can be accessed by all FSD users. The company is also expected to keep these rollouts more frequent than before.

Hardware 3:

While making this announcement, Tesla CEO, Elon Musk said the FSD 12.5.1 rollout likely to be visible to cars with Hardware 4. However, Musk confirmed that the company is working on Hardware 3 support.

“It takes considerable software efforts to optimize the code enough to run on HW3. It also needs to be validated separately.” Musk wrote on the social media site X.

He previously shared that this hardware limitation is Model Y only in the initial releases. This delay is related to the fact that software should perform well when adapted.

FSD 12.5.1 has a 5 times increase in parameters and it’s important to run those in HW3. Nearest, the company can rollout FSD 12.5.1 support for HW3 in about 10 days, which could be somewhere in early August.
