Early this morning Tesla released FSD v12.5.3 with Actually Smart Summon. The update is version 2024.27.20 and while the FSD release notes remain the same, we now have the long-awaited Actually Smart Summon feature (cute acronym here).
While this release is currently limited to hardware 4 (AI4) vehicles, it’ll be the first time that any type of Summon is available on vehicles without ultrasonic sensors. When Tesla removed ultrasonic sensors in the Model 3 and Model Y in October of 2022, those vehicles also lost access to features such as Summon (regular and smart), Autopark and Park Assist.
The rollout of FSD v12.5.3 and Actually Smart Summon is currently going out to early-access customers, which mostly consists of popular influencers. However, it’s only going out to vehicles with AI4, and it’s not clear when it’ll be supported on HW3. When Tesla first rolled out FSD 12.5 to HW4 vehicles, it took about a month before it became available on HW3 cars. Since the hard work of porting the new FSD model to HW3 vehicles is already done, we don’t expect a huge delay in getting the improved Summon feature available on HW3.
Update: Tesla has now begun rolling out the update to HW3 vehicles!
Actually Smart Summon Features
Actually Smart Summon includes several new features over the previous version of Smart Summon that was available on vehicles with USS. First, its capabilities seem to be greatly improved over its predecessor since it now leverages the newest FSD model in FSD v12 and uses end-to-end AI, instead of relying on hand-coded features to control the vehicles.
Tesla is now also providing a live camera view in the app as expected after an app update showed evidence of live camera feeds. When you open the Summon view from the app, you’ll be shown a matrix of four live camera views in the app.
While using Smart Summon, you’ll be presented with a live video of the vehicle’s front camera, giving you even better access to the vehicle’s surroundings.
With the updated Summon, you have two choices. You can use the original summon, “Dumb Summon,” which only allows you to move your vehicle in a straight line — forward or back. Or you can use the new Smart Summon which allows you to have the vehicle go to your current location or a different spot you pick on the map.
To use Summon, you’ll need to hold down the “Come to Me” or “Go to Target” buttons. Whenever you let go of the button, the vehicle will stop. This lets you easily stop the vehicle when you notice an obstacle the vehicle may have missed.
Future Features
In the release notes, Tesla points out that there will be additional features coming to Smart Summon in the future. These features include HomeLink and MyQ garage support, which will allow the vehicle to open a garage door before it starts moving. It’s worth noting that this feature was available in the previous version of Summon, but Summon just didn’t work well enough to trust the vehicle to open the garage door before it started moving. Actually Smart Summon (just called Smart Summon in the app), will be a huge improvement, but whether you’ll want to trust it with opening and closing your garage door is still to be determined.
Tesla also says that it’ll improve the summoning experience by not requiring you to hold down the buttons in the app and that it’ll also support longer ranges in a future update. The current version of Summon is limited to about 65 meters (213 feet). While Tesla doesn’t specify the range of Actually Smart Summon, it’s expected to be about the same as the previous version with an even longer range coming in the future.
Actually Smart Summon is currently limited to users with FSD on the latest FSD update (2024.27.20). This update is expected to go out to additional customers with HW4 and FSD in North America, but it’s also expected to support HW3 soon.
Actually Smart Summon will be available outside of North America and to customers with Enhanced Autopilot or FSD in the future. However, this won’t happen until FSD 12.5.3 is stable and becomes a part of the regular Tesla updates. Tesla currently includes FSD 12.3.6 with the non-FSD specific updates. As we saw with Autopark, Actually Smart Summon is expected to roll out to North America first, then gradually roll out to additional countries. Autopark was first released in North America on an FSD-specific update in March 2024 and then became available in Europe in late June.
Robotaxi Event
This weekend we shared the news that Tesla will be holding its Robotaxi event at an outdoor, city-like movie studio where they’re expected to show off the Robotaxi in action and even let attendees ride along in the vehicle. Tesla also started gathering additional data in some of the public areas of the movie studio to help improve Robotaxi performance at the event (Robotaxi concept designs).
Actually Smart Summon could be one of the reasons the Robotaxi event was moved from August 8th to October 10th. We’re now only a little over a month away from this event now, and Actually Smart Summon may be our first glimpse into what the Robotaxi will be capable of.

Tesla’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.
Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.
Semi Factory & Production Ramp
Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.
Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.
Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.
Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.
New Tesla Semi Features
Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.
New Electric Power Take-Off (e-PTO)
The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.
Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.
On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.
46 Semi Charger Sites Coming

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.
This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.
The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.
Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.
B-pillar Camera Recording and Dashcam Viewer
With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.
This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.
These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.
However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.
Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough
We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.
For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.
While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.
Cybertruck Also Missing Improved Sentry Mode
Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.
Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.
Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.
Adaptive Headlights
Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.
All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.
If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.
Legacy Model S & Model X
As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.
Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.
These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.
While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
