The first signs of Tesla's FSD Beta 10.12 finally surfaced
yesterday as Tesla employees started receiving the internal beta.
The internal beta initially had a version of 2022.12.3.10, but
it looks like Tesla has aleady issued an update with version 2022.12.3.15 (FSD Beta 10.12.1).
It's not clear yet whether this will be the exact version that
will be rolled out to public testers or if additional updates will be made.
If Tesla finds any major issues, they'll want to fix them before
rolling out the update to external testers.

FSD Beta 10.12 introduces new vehicle models for almost every
vehicle type.
Some of the vehicles have been completely redesigned and are
more detailed and realistic looking than the previous models.
For example, a sedan now has wheels, windows and a glass roof,
instead of the previous simplistic look that resembled a Model S keyfob.
New Brake Lights
Although brakes lights were already displayed as of beta 9.0, Tesla is now displaying the third brake light as well, which
has been required in the US since 1986.
Open Doors

FSD Betas have been able to detect and stop or go around
vehicles with open doors for a while now, but Tesla will now show open doors in the
visualization.
When a surrounding vehicle's door is open, the 3D model will
also show the open door and highlight the door in orange.
With this release, FSD Beta now detects and visualizes turn
signals in addition to brake lights.
The car will reportedly react to turn signals it has detected as
well, which should help understand the intentions of other vehicles.
Two Steps Forward, One Step Back
The last major FSD Beta release was version 10.11, which was
first seen more than two months ago.
Tesla has been working on beta 10.12 for a while now and the
amount of changes included in this update are huge according to Elon.
Musk said that due to the amount of changes in this beta, we can
expect two steps forward and one step back.
This is a big one! Expect some two steps forward, one step back
situations. These will be great ironed in point releases, hence ~10.12.2 or 10.13 for wider beta release.
- Elon Musk
There will be some issues, and in certain situations FSD may
have regressed.
Tesla plans to fix any issues that arise with minor revisions to
this release. Expect to see additional FSD Beta 10.12 releases such as 10.12.1 and 10.12.2 in the coming
weeks.
Current Beta Testers
As we have seen with other recent betas, it may be a while until
all current beta testers receive this latest beta.
With beta 10.11, we saw two revisions before the majority of
testers received the beta. We may see a similar situation with this update, given the amount of changes
that were made.
If you're a current beta tester, you may be waiting a couple
weeks before getting this updated FSD Beta.
Additional Testers
There haven't been any signs of Tesla adding additional beta
testers in the US since late 2021.
Elon has previously said that he hopes that Tesla will be able
to add more testers who have opted in to the beta and have a Safety Score of 95 or greater in later revisions of beta 10.12.
We have the technical releases notes for FSD Beta 10.12, but
Reddit user asimo3089 did a great job at interpreting the release notes to give us a better
understanding of what Tesla has improved in this update.
1. Your car better understands what is and is not drivable space.
This makes it more confident in easy situations, and more capable in tricky situations. Your car can
also now use medians for difficult left turns, and accelerates quicker to complete turns.
2. Your car now has a better idea of objects blocking camera views.
Creeping should be less scary.
3. Improved path predictions of where other others on the road will
be. This gives your car better decision making for turns.
4. Sounds like: Your car will drive itself to safety much more
smoothly if your car finds itself in a place it shouldn't be. Better problem solving?
5. Your car should better see the lanes on the road, and how many
of them there are, thanks to new data. This gives better turn confidence and path planning during a turn.
6. Your car is now trained on 180,000 new clips related to what
lanes look like.
7. Your car is less likely to panic brake in a yellow light
scenario, and has a better understanding of lane guidance when going through an intersection.
8. Road edges and road lines are now more accurate.
9. Your car now better understands visibility from the cameras,
thanks to 30,000 new video clips of training data.
10. Speeds of motorcycles, pedestrians and cyclists is now more
accurate. Plus, your car now better predicts which direction a pedestrian is walking.
11. Your car is now less likely to confuse a parked car and an
idling car thanks to 41,000 new clips of training data. This should result in fewer "phantom brakes" or
silly lane changes.
12. Your car now better understands objects that are far away from
you.
13. Your car will plan a better path around vehicles with car doors
open.
14. Objects that are not pedestrians, cyclists, etc, should have
more accurate speed predictions.
15. When changing into an adjacent lane, your car will look further
ahead at vehicle speeds. If somebody up ahead is braking, your car will handle it more
comfortably.
16. Your car used to only predict acceleration (Not speed) for
objects moving adjacently. Now your car will predict acceleration of all moving objects including
objects accelerating across your path.
17. New 3D models for vehicles on your screen. You'll also be shown
vehicles with their doors open.
18. Tesla retired a few old systems and gained 2 frames per second,
per camera, resulting in better performance while self driving.
FSD Beta 10.12 is currently only available to employees, but we
may see a wider release in the next couple days that includes public testers.
However, it could be several weeks before all current testers
receive this update.
More details will surely be uncovered about this beta in the
next few days. Stay tuned for more.

Last night on X, Elon Musk confirmed that Tesla will be expanding the service area for its Robotaxi Network pilot in Austin, Texas, this coming weekend. This is the first official confirmation we’ve had of a date for expansion, following news that Tesla is hiring more Vehicle Operators and plans to expand the Robotaxi supervisor ratio in the coming months.
This is a sign of Tesla’s confidence in the Robotaxi pilot program and its current FSD builds.
Expanding to a larger service area in Austin this weekend
The announcement confirms the sights we’ve been seeing of Tesla’s engineering validation vehicles focusing on areas outside the initial geofence. This public test shows that Tesla was likely finalizing FSD builds and gathering the necessary safety data to push the boundaries for the service, and this upcoming weekend’s expansion will be the first direct result of that work.
Given the increase in service zone size, this expansion will also likely include the addition of more vehicles to the initial Robotaxi fleet of approximately 20 vehicles. We expect the new number to be anywhere from 30-50 vehicles serving both the original and new areas, combined, based on Tesla’s previously expected rollout schedule.
What to Expect
While the exact new boundaries haven’t been released, it is almost certain that the expansion will include the South Congress Bridge and the downtown core areas of Austin. Expanding into a dense urban zone will include more complex intersections, heavy pedestrian traffic, and a unique road layout. That is a major vote of confidence for Robotaxi FSD’s capabilities.
The expansion will also help Tesla to close the service area gap with Waymo, its primary autonomous competitor in the city. This quick expansion is a sign of just how scalable Tesla’s vision-only approach is, versus Waymo’s arduous and drawn-out mapping processes.
We also expect that with this first service zone expansion, Tesla will continue to invite more people to its Robotaxi Network in the coming weeks. Tesla has already sent out various rounds of events, as they’ll need users to continue using the system. If you’re waiting for an invite, it may be time to start getting excited about the next rollout.
We’ve been hearing about Grok, xAI’s AI assistant, coming to Teslas for almost two years now, but this is finally coming to fruition soon. XAI unveiled Grok 4 last night, but the entire stream didn’t mention Teslas. However, Musk later posted on X that Grok will arrive in Tesla vehicles “by next week.”
Between leaks and the Grok mobile app, there’s a lot we already know about Grok, but there are a few missing pieces that will be cleared when it finally arrives.
Next Week, or Next Next Week?
Musk said that Grok would arrive by next week, meaning it could arrive before then. However, based on how Musk typically states Tesla timelines, there are a few things to consider that give us a better idea of what to expect.
First, whenever Musk posts a Tesla timeline on X, he typically means when it’ll be released to employees and not a public release. Expect this to be the same thing.
Tesla releases software updates to employees first for a final round of testing before starting a gradual release to the public. Sometimes issues are found, especially with FSD updates, and the update needs some fixes before being released publicly. So expect employees to get it by next week, and not necessarily normal Tesla owners.
The second part to this is that Tesla always rolls out their updates gradually, so when it does finally arrive, it’ll only be available on a small percentage of vehicles. Tesla will gradually monitor issues and logs, continuing the rollout as long as no major issues are found.
Which Software Update?
The entire Grok UI was already included in software update 2025.20, but it’s not exposed to users. Typically, a new feature like Grok requires a vehicle update to be added; however, this version may be different, as it’s locked behind a server-side configuration.
Tesla likely has the ability to enable it for all supported vehicles with a simple switch. However, we feel more confident in it being rolled out in Tesla’s next major update, which is likely to be 2025.24 or 2025.26. Rolling it out in a new update aligns with how Tesla has historically introduced features.
If they turned it on for everyone at the same time, they could be exposing everyone to potential new issues, rather than only a smaller segment of users. While Grok is now well-tested through X and the Grok app, there are several elements that are new in Teslas, likely including the ability to control various vehicle functions, such as opening the glove box or other capabilities that voice commands are currently capable of. The Grok interface in the vehicle is also entirely new and may have some bugs associated with it that will need to be addressed, especially if they impact other features.
What we can likely expect is that Tesla will make some tweaks or bug fixes to Grok with the next major update that weren’t included in update 2025.20 and they’ll begin rolling it out to employees and then customers.
Supported Vehicles
Speaking of supported vehicles, thanks to the behind-the-scenes look at Grok, we have a good idea of the vehicles that will be supported. Tesla uses the same code for most of its vehicles, but then it’s compiled for each type of hardware. However, only the needed code is compiled for each vehicle, meaning that some pieces are left out entirely. Unfortunately, Grok code is not included in Intel software builds, meaning that only AMD Ryzen-based vehicles will receive Grok, at least initially.
We’ve seen Tesla go back and add support for Intel vehicles after it initially released a feature for AMD vehicles. We saw this with the weather radar overlay and several other features in the past. However, Tesla has been developing code with web technologies lately. While this makes development easier, it just doesn’t perform as well on the slower Intel hardware, causing it to be left out. We saw this with the new Dashcam Viewer, which is entirely coded in HTML, CSS, and JS. The new viewer was available on HW3 and HW4 vehicles, but only those that included the Ryzen infotainment processor.
Grok is coming to Tesla vehicles very soon. Next week at the latest.
There’s a lot we’re expecting in Grok for Teslas. Some people will absolutely love it because it’ll completely transform their drives from a singular experience to feeling like they have a knowledgeable person sitting right next to them. Given the recent controversies surrounding Grok, some people will strongly oppose it. Hopefully, Tesla makes it easy for those users to turn off Grok.
The voice command system, which is activated through the steering wheel, is expected to be replaced with Grok. This will mean that you’ll be able to talk to your vehicle much more naturally, rather than having to remember specific syntax and commands, which should be a major improvement.
We’re personally looking forward to just being able to ask questions that pop into our heads while driving, such as What’s the date of Tesla’s next event, or How many miles away is Mars? Knowledge will be available at the touch of a finger and more accessible than ever.
Grok is also expected to support continuous conversations, meaning that you’ll be able to hold a conversation with it and go back and forth about a certain topic. While there are hints of a wake word in the code, for now, it seems like you’ll press the steering wheel button once to activate it, and then again to turn it off.
For those excited about AI and Grok, this will be one of the biggest additions to Tesla’s software in years, possibly only rivaled by the Dashcam / Sentry Mode feature and FSD Beta.
It shouldn’t be long now before we all have a chance to try it out for ourselves.
