Musk says Tesla is ready to release FSD 12.4 next week
Not a Tesla App
Less than two weeks since its last FSD update, Tesla is getting ready to release FSD v12.4, with CEO Elon Musk hinting at significant improvements. The current version, 12.3.6, introduced Autopark and High Fidelity Park Assist for vehicles equipped with ultrasonic sensors in the U.S. and Canada, along with minor fixes for FSD.
Just an hour ago, Musk shed some light on Tesla's next FSD update. Through his X account, Musk teased the imminent release of v12.4, stating, "Probably start rolling out 12.4 next week." Moreover, he provided insights into the development process and the features users can expect in the upcoming 12.4 version, as well as v12.5 and v12.6.
What to Expect in FSD v12.4
Musk says that FSD 12.4 has extensive retraining of AI models that particularly focuses on refining the comfort of passengers by addressing concerns around abrupt acceleration or braking. Musk previously commented on the next versions of FSD saying that FSD v12.4 and 12.5 would be major improvements, and while v12.4 may be a major step forward, it looks like its main focus will be on being more natural and smoother.
"Probably start rolling out 12.4 next week."
FSD v12.5 and v12.6 to Handle More Complex Scenarios
Looking ahead, Tesla is already laying the groundwork for future updates according to Musk. The CEO previously stated that Tesla is constantly working on FSD updates that are three to six months ahead of what’s in production, so they have a good idea of what the software will be able to handle in the future.
Today on X, Musk said that there's ongoing testing for FSD versions 12.5 and 12.6, which involves tackling complex scenarios. Musk says this includes navigating narrow, one-way roads and handling unexpected road closures, requiring the vehicle to reverse and find alternate routes.
Actually Smart Summon in v12.5?
Tesla’s Autopilot lead, Ashok Elluswamy, previously talked about how FSD would gain the ability to go in reverse when Tesla is ready to release Actually Smart Summon. If the ability to reverse is still tied to some of the abilities of Actually Smart Summon, then, it’s possible we may see Tesla’s better summon implementation in version 12.5 or 12.6.
Vehicles to be Able to Communicate with Fleet
Musk also gives us some insight into vehicle communication, saying vehicles will need to be able to communicate with the fleet so that you "don't get a whole bunch of Teslas stuck down a road."
Instead of vehicle-to-vehicle communication, Tesla will likely have vehicles report back to the "mothership," where Tesla can aggregate data and report it to nearby vehicles. This is similar to how vehicles report traffic today, instead of talking directly to each other.
Spending on AI
Tesla's commitment to advancing its AI capabilities is evident through its substantial investments. Musk recently emphasized the company's dedication to spending around $10 billion throughout 2024 on training and inference AI. Musk said that any company that isn’t spending billions on AI this year just won’t be able to compete.
Expansion of FSD
Tesla appears ready to start the expansion of FSD, and it looks like China may be up first. Musk's recent visit to Beijing to discuss a potential FSD rollout and data sharing shows that Tesla is ready and serious about FSD's expansion.
While FSD's rollout in China appears promising, Musk remains cautiously optimistic about expanding into other markets. He believes that FSD v12 is ready for supervised FSD in left-hand drive (LHD) countries, while right-hand drive (RHD) markets like the UK and Australia may require additional time.

Another quarter has passed, and that means it’s time to submit questions and vote for Tesla’s Q2 2025 Earnings Call. While Q1 was a tough quarter for the company, Q2 saw some recovery in sales, although there’s still some work to be done.
However, there’s always a lot to be excited about during Tesla’s Q&A session, where we usually learn a lot about future software improvements and upcoming vehicles. We may hear more about FSD Unsupervised, Robotaxi, or the more affordable vehicle, or its upcoming larger 6-seater Model Y, the Model Y L. Tesla also mentioned a potential FSD price hike back in the Q1 2025 Earnings Call, so that could be something that is brought up as well.
Tesla’s Q2 So Far
Tesla has already released their Q2 2025 Production and Delivery numbers, which were up from Q1 of this year, but still down compared to Q2 last year.

How to Submit & Vote
Tesla lets shareholders submit a question that will be voted on and may be answered during the Q&A session. To submit your own question or vote on an already submitted question, you’ll need to be a verified shareholder. You can go to Say’s platform and link your brokerage accounts.
Once it is verified, you’ll be able to log in and vote your shares on your own question, or on someone else’s question.
Here’s the link to get started on Say’s Tesla Q&A. You must submit your questions and votes by July 23rd, 2025, at 4:00 PM EDT.
Top Questions So Far
Unsurprisingly, people have already been submitting questions, and here are the top ones so far.
Can you give us some insight how robotaxis have been performing so far and what rate you expect to expand in terms of vehicles, geofence, cities, and supervisors?
What are the key technical and regulatory hurdles still remaining for unsupervised FSD to be available for personal use? Timeline?
What specific factory tasks is Optimus currently performing, and what is the expected timeline for scaling production to enable external sales? How does Tesla envision Optimus contributing to revenue in the next 2–3 years?
Can you provide an update on the development and production timeline for Tesla’s more affordable models? How will these models balance cost reduction with profitability, and what impact do you expect on demand in the current economic climate?
Are there any news for HW3 users getting retrofits or upgrades? Will they get HW4 or some future version of HW5?
When do you anticipate customer vehicles to receive unsupervised FSD?
And here are some other ones we found interesting:
Have any meaningful Optimus milestones changed for this year or next and will thousands of Optimus be performing tasks in Tesla factories by year end?
Are front bumper cameras going to be necessary for unsupervised full self driving? If so, what is the companies plan to retrofit vehicles that do not have them?
Will there be a new AI day to explain the advancements the Autopilot, Optimus, and Dojo/chip teams have made over the past several years. We still do not know much about the HW4.
Earnings Call Details
Tesla will hold its earnings call on Wednesday, July 23rd, at 4:00 PM EDT. It's still early for an access link, but we’ll make sure we have a link up on the site before the earnings call that day.
If you do miss the earnings call, no worries. We will provide a full recap following the call, and we’ll also do some in-depth dives into what was said and what we know.
Tesla’s Summer Update, 2025.26, has finally launched, bringing with it a batch of interesting new features for some, and a bunch of quality-of-life improvements for everyone else.
Grok AI Assistant
The star of the Summer Update is Grok, xAI’s conversational AI assistant, which has now landed in Tesla vehicles. For now, it's available in any Tesla that has an AMD processor and is potentially coming to Intel-based vehicles in the near future. The feature is also only available in the U.S., but it’s expected to expand to other regions — hopefully soon.
Grok is in its first iteration as an in-vehicle assistant, and for now, cannot control the vehicle, which means that Tesla’s voice command system is still intact. However, there is a lot it can do already. Grok is activated by pressing and holding the voice button (right scroll wheel on older vehicles), while a short press of the button is still reserved for voice commands. Grok will support a wake word in the future, letting you activate it without pressing a button.
You don't need to sign into Grok to use it in your Tesla!

Once Grok is open, which can also be done by tapping the Grok app icon, users can tailor the AI personality according to their preferences by selecting a persona and voice of their choice.
There are also several other settings for Grok under the settings button. You can enable NSFW mode, Kids Mode, or disable access to your vehicle’s location.
Grok has contextual awareness of your vehicle location, which means it can provide relevant answers to questions like “Where should I go for dinner?”
Logging In Not Required
Grok is free with Premium Connectivity, or if you’re using your phone’s hotspot feature or connected to WiFi, so anyone can try it for free. In fact, you don’t even need to log in to start using Grok. However, logging in adds some additional features.
If you’d like to log in, you can do so by scanning the QR code in the vehicle, which will provide chat management and transcripts, SuperGrok access (if you pay for a subscription), and better privacy control.
Tesla has added a new Light Sync feature that pulses the vehicle’s ambient lighting in sync with the music being played. This option is turned on under Toybox > Light Sync. There are also a few options, including the ability to match the ambient light colors to the album’s artwork, instead of using your selected color.
In addition, in Park you can enable Rave Cave when parked, which cranks up the ambient lighting brightness to the maximum.
Dashcam App Update
The Dashcam app now allows you to adjust playback speeds, just like the older Dashcam Viewer, which is still used on Intel-based vehicles.
In addition to adjusting playback speed, you can now adjust the video view so that it’s displayed without being obstructed by the buttons at the top (video below). The difference is small, but could be useful if you’re trying to see something slightly out of view or that’s hidden behind the top Dashcam buttons.
While the Cybertruck has also received the updated Dashcam Viewer with this update, it does not have the new B-pillar camera recordings like other HW4 cars.
Sentry Mode is getting one of the best uses of the vehicle’s ambient lighting that we’ve seen so far. The ambient lighting will now slowly pulse red while Sentry Mode is activated to grab someone’s attention, instead of just relying on the vehicle’s display.
While you can disable Sentry Mode sounds, we’d love to see an even more stealthy Sentry Mode that also disables the ambient lighting and screen, allowing the vehicle to record without anyone being aware.
Since the ambient lighting is being used in this case to make people more aware of a feature, Tesla could also use it in other modes, such as Dog Mode.
There are a lot of potential uses for ambient lighting. Tesla can make it glow while the vehicle is charging, with the brightness potentially related to the vehicle's charge level.
When you navigate to a Supercharger, new icons in the charger list will indicate locations that require valet service or pay-to-park access.
Upon arrival at the location, a notification will appear on your screen, displaying important details such as access codes, parking restrictions, level/floor information for parking garages, and restroom availability. This information will also be available on the site card in the navigation.
Equalizer Presets

Tesla has moved the audio settings from the music player, directly into the vehicle settings — making them much easier to find. In addition to creating a new “Audio” section in settings, you can now create and save equalizer presets.
Each preset can have a name, custom EQ settings, and a setting for immersive audio.

Onboarding Guide
Not a Tesla App
Tesla has introduced a new Onboarding Guide for new owners. The guide covers driver settings, touchscreen use, steering wheel and seat setup, and how to control key portions of the vehicle, including lights, wipers, and Autopilot features.
The Onboarding Guide is automatically initiated when a new owner accepts delivery of a Tesla, or can be manually initiated at any time by going to Controls > Service > Onboarding Guide.
This appears to only be available for the new Model 3 and new Model Y.
In typical Tesla fashion, this 2025.26 update is rolling out gradually in small waves initially. Three waves have already gone out, so all signs are looking good for it going into a wide release soon.
