FSD Supervised v14.3.9 starting to roll out shortly This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough. It may also engage if we detect you’re heavily distracted or have accidentally disengaged FSD

Terafab will be built in Grimes County, Texas In April, we broke ground on our research fab on the North Campus of Giga Texas – the precursor to Terafab. Both Tesla & SpaceX will need far more chips than current & future global production can supply. This is why we're building the largest chip manufacturing facility ever, with the goal of producing over 1 terawatt of compute per year The future is built in Texas spacex.com/updates#terafab

FSD v14 Lite now without brake confirm. Tap & go, just like AI4. This update also brings the Self-Driving app to AI3 vehicles – including streaks And many more improvements
FSD v14 lite new build on AI3 starting from park WITHOUT brake confirm! Such a big improvement and makes using it feel so much better.

FSD v14 Lite (for Tesla AI3 hardware vehicles) review. This is the version that’s likely going to wide release.
A few drives and over 100 miles in with the new FSD v14 lite update and here are my thoughts: V14 lite was already quite good and this update brought some HUGE UI improvements which makes it feel so much better. Tesla has added a great Start Self Driving from park change where you now don’t have to confirm by pressing the brake pedal to start FSD from park. Seems like a minor change but it’s a huge quality of life improvement. Tesla has also added the same parking options tab as AI4 cars, when approaching your destination it pulls up the tab to show you your parking options at destination. It shows the blue P and you can press it mid drive as well. Something else to note is Curbside has now been changed to Pull Over just like AI4 FSD v14.3. The Self Driving App has been added in this update just like AI4 cars, it tracks your overall percentage of FSD usage. Doing the math on my current usage/odometer it seems like the tracking started when I installed 2026.8.6. The Self Driving app shows you instructions on how to use FSD too as well as monthly stats. This new update has also brought streaks! Just like AI4 cars it tracks your continuous streak of FSD usage. It also shows you how many days in a row you have used FSD. Got a 100 mile streak tonight and it showed confetti just like AI4. Highway performance is SO good still. Keeps a consistent speed with no unnecessary lane changes and I saw zero left lane camping tonight. It handles high speed curves so perfectly and doesn’t ping pong and it feels so dialed in. Dare I say almost as good as AI4, almost all the way there- just wish it would accelerate stronger in hurry onto the highway when merging from the on ramp. Great lane choices and passing decisions. No traffic so it sat at 2mph slower than it used to when no cars around in standard and hurry but if a quicker car would come by it would speed up a bit. DMS might also be slightly more sensitive but it was dark out, will confirm with some more driving later today. City streets: this update is similar than before but seems to be slightly more confident around city streets. Hurry was a bit quicker than before but I wish it would accelerate slightly stronger in hurry profile only. Really good yellow light performance on the three I encountered and had smooth braking and no overreactions. I did however see the weird turn signal bug for the second time ever tonight at a traffic light so this is still present with this update as well as the slight steering wheel wobble at around 40mph and still way improved over v12.6.4. They definitely improved the way it leaves stop signs and lights though, slightly more linear and smooth acceleration from a stop. Obeyed both no right on red signs I encountered too. Dips and speed bump speed is perfect as it was before too. Most importantly, FSD v14 lite feels so much safer than v12.6.4. Parking might be slightly improved in this build where it took a better approach angle like I mentioned it needs to in the previous build reviews. It still doesn’t straighten out wheel at the end which I would like to see changed. It also still “double stops” when almost done with a parking job backing up to a supercharger space. Speed might be a tad quicker than the last build as well but will get some more parking in later today to confirm my findings. Overall, this update (2026.20.6.10) brought some massive UI changes, quality of life improvements, and really made this update feel like v14 even more. Absolutely incredible what they’ve accomplished with v14 lite on HW3 cars. Feels like I got a new car. Thanks @Tesla_AI and UI teams for all the hard work getting this out and I really hope it rolls wide soon!

FSD Supervised is advanced real-world AI
Rapidfire epic moments on FSD V14.3.5 1) FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley. 2) Insane speed to vehicle cues. As FSD approaches the intersection at the end of the small alley, it yields for traffic, but at the SECOND the car to our left slows, it realizes they’re letting us go and executes with zero hesitation. You can see the nose of the vehicle on the far left side of the shot here to gauge reaction speed. 3) FSD approaches railroad traffic, clears the vehicle intersection, but stops shy of first RR track instead of queueing behind lead car, ignoring the human who decided to foolishly stop in front of the track. This is why I’m bullish. This tech is just a constant mindblower when you’re out here using it.

It’s pretty incredible what the @Tesla_AI team just accomplished with FSD V14 Lite on 7-year-old HW3 hardware: • HW3 has roughly 1/8th the memory bandwidth of HW4 • HW4 is ~3-5x faster overall for FSD workloads • HW4 cameras have much higher resolution than HW3. They pulled some magic here, absolutely amazing.

This is how good FSD has gotten. And I’ll admit, I was a little nervous when the light turned green because I thought the car was going to try and go for it. But it didn’t. It waited for the officer’s hand signal, then it proceeded. Incredible that a car intuitively knows this!

FSD 14.3.4 just being amazing. Handling all the traffic in San Francisco. Watch until the end. It was amazing just to sit in my seat and witness greatness. FSD continues to impress my family and me. This technology will change the entire world, one person at a time.

v14 Lite Release Notes: – Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3. – Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios. – Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering. – Introduced parking, unparking, and reversing capabilities. – Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside. – Speed Profiles are now available at all times, to further customize driving style preference.
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks. This build distills the driving behavior from AI4’s v14 series into both the camera and compute config of AI3. It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.

Nice work by the @Tesla_AI team! The AI3 computer only has ~15% of the effective memory bandwidth of AI4, so this was a tough challenge.
Drove Tesla FSD v14 Lite for an hour tonight on my M3 HW3 Tesla WAYYY better than v12.6.4. I know smoother is often the word used to describe a great build, but it just it fits for this update, very smooth. Tested HWY, residential, and back roads. All great! The parking feature worked exactly the same as using it with the Cybertruck. This v14 lite, on a HW3, feels as good as v14 to me on an AI4 vehicle. Very impressive @Tesla_AI — superb engineering feat! Thank you again for bringing the older fleet up to par 🙏
