If your Tesla has Hardware 3, FSD (Supervised) v14 Lite is the build made for your car. Tesla started rolling it out to HW3 Model 3 and Model Y on June 29, 2026 with software version 2026.20.5.1, according to Not a Tesla App, and it went to a wider release in July with 2026.20.6.11, as Tesla Oracle reported.

HW3 v14 Lite vs HW4 v14 at a glance
| HW3: v14 Lite | HW4: v14 | |
|---|---|---|
| Model | Distilled from HW4 v14, using it as a guide (release notes) | The full v14 model |
| Computing power | Less, so it cannot run the full model (Tesla Oracle) | Runs the full model |
| Supervision | FSD (Supervised), driver must stay attentive | FSD (Supervised), driver must stay attentive |
What v14 Lite changes, per Tesla’s release notes
According to the official notes, as published by Not a Tesla App:
- Tesla distilled what it learned on HW4 v14 into HW3, using HW4 v14 as a guide for how to handle scenarios.
- Better responsiveness at merges and forks, around pedestrians, at traffic lights and when cars cut in.
- Fewer false slowdowns, smoother steering and more consistent lane centering.
- New parking, unparking and reversing.
- Arrival Options, so you can pick where it parks: a parking lot, the street, a driveway or the curb.
- Speed Profiles available at all times.
A later build, 2026.20.6.10, added the Self-Driving app, streaks and the option to turn off the brake confirmation when starting from Park, per Not a Tesla App.
What it does not change
Lite is the honest word here. HW3 has less computing power than HW4, so it will not run the same full model, as Tesla Oracle notes. And it is still FSD (Supervised). Tesla’s own notes say you must remain attentive and that it does not make your vehicle autonomous. Hands ready, eyes on the road.

Owner to owner
If you have a 2023 Model Y or another HW3 car, try the new parking and Arrival Options on a quiet lot first, set a Speed Profile you are comfortable with, and see how it handles your regular commute. Then tell us how it went. Which build are you on, and what improved for you?
