With FSD V13.2.6 continuing to make its way to AI4 vehicles, Tesla has been on a streak with minor FSD improvements since the launch of FSD V13 just a little over two months ago.
FSD V13 brought a new slate of features, including Start FSD from Park, Reverse, and Park at Destination. It also introduced full-resolution video input using the AI4 cameras at 36hz and made use of the new Cortex supercomputer to get faster and more accurate decision-making.
So, what’s next with FSD V14? Tesla gave us a sneak peek at what’s next for FSD.
FSD V14
The standout feature of FSD V14 will be auto-regressive transformers. While that’s a complex term for those unfamiliar with AI or machine learning, we’ll break it down.
Auto-Regressive
An auto-regressive transformer processes sequential data in time, using that information to predict future elements based on previous ones. Imagine completing a sentence: You use the words already written to guess what comes next. This process isn't just about filling in the blank; it's about understanding the flow of the sentence and anticipating the speaker's intent.
FSD could analyze a sequence of camera images to identify pedestrians and predict their likely path based on their current movement and surrounding context. The system's auto-regressive nature allows it to learn from past sequences and improve its predictions over time, adapting to different driving scenarios.
Today, FSD reacts to what it sees, but soon it’ll be able to anticipate what will help, much like humans.
Transformers
The second part of that term is transformer, which is a component used to understand the relationships of elements inside a time sequence. It identifies which parts of the input are most crucial for making accurate predictions, allowing the system to prioritize information much like a human would. Think of it as weighing different pieces of evidence to arrive at a conclusion. For example, a transformer might recognize that a blinking turn signal is more important than the color of the car when predicting a lane change.
Putting It Together
Putting all that together, Tesla’s use of auto-regressive transformers means they’ll be working on how FSD can predict the plans and paths of the world around it. This will improve FSD’s already powerful perception and allow it to predict how other vehicles and vulnerable road users (VRUs) will behave.
What it all comes down to is that FSD will be able to make better decisions and plan its paths by making more informed, human-like decisions. That will be a big step towards improving V13 - which already has some very effective decision-making.
Larger Model and Context Size
Ashok Elluswamy (Tesla’s VP of AI) stated that FSD V14 will see larger model and context sizes in FSD V14, which coincidentally are listed in the upcoming improvements section of FSD V13.2.6. If we compare what Ashok said to what’s listed in the upcoming features section, the model and context sizes should grow by 3x.
Interestingly, Ashok says that AI4’s memory limits context size. Context is essentially the history of what the vehicle remembers, which is used for future decisions. Since this information is stored in memory, it’ll always be limited by memory, but it’s worth noting that Ashok mentioned that Tesla is restricted by the memory in the AI4 computer.
Leverage Audio Input
Tesla is already gathering audio data in existing FSD versions so that it can start training models with audio as well, truly making FSD more human-like. According to Ashok, FSD V14 will be the first version to take advantage of audio input for FSD driving. This will primarily be used for detecting emergency vehicles, but we can see this expanding to other sounds that help humans adjust their driving, such as car crashes, loud noises, honking, etc. At the very least, FSD could be more cautious when hearing a noise that matches an accident or vehicle honking.
FSD V14 Release Date
We haven’t heard from Elon Musk or Ashok Elluswamy about when FSD V14 will arrive. Ashok previously stated that FSD V13.4 would see audio inputs being used, but at Tesla’s earnings call, Tesla said that audio input would become relevant in V14, making it seem like Tesla may scrap V13.4 for V14.
Since Tesla is planning to launch their Robotaxi network in Texas this June, which is just four months away, FSD V14 may be the version used for its autonomous taxi fleet.

Tesla’s much-anticipated official entry into the Indian market appears to be shifting to a higher gear, with recent reports from Business Standard (paywall) indicating that Tesla is now looking into establishing Gigafactory India. Business Standard points to Tesla exploring land options in Satara, Maharashtra.
Satara is about 250km (155 mi) from the Port of Mumbai, placing it in an excellent location to easily receive parts and materials from other countries, as well as ship completed vehicles elsewhere around the world. The potential facility is reportedly planned as a “Completely Knocked Down” or CKD assembly plant, which means that Tesla would import parts and then assemble them locally.
This is key to Tesla’s strategy in addressing India’s traditionally high import tariffs on fully built vehicles, which have been a major hurdle for Tesla in the past. This push aligns with India’s updated EV policy, which calls for reduced import duties on EVs priced at $35,000 USD or above for companies that commit to investing at least $500m USD in local manufacturing facilities between 2024 and 2027.
According to the report, Tesla is prepared to invest substantially more, with figures around $2-3 billion USD cited for a plant capable of doing final assembly on up to 500,000 vehicles. Tesla supposedly aims to roll out the first locally assembled vehicle from the facility no later than March 2026.
Building the Indian Foundation
Beyond just manufacturing plans, Tesla has been actively laying the groundwork for its future Indian operations. Tesla has reportedly finalized leases for its first showrooms in Mumbai and Delhi - two of the largest cities in India. An office space in Mumbai to headquarter Indian operations is also on that leasing list.
Tesla has also begun to hire its initial tranche of employees, with over 30 positions already posted. Tesla is also hiring Autopilot Vehicle Operators in several locations, indicating that Tesla intends to test at least the FSD suite in one of the most complex traffic situations around the world.
Elon Musk also confirmed that he plans to visit India and speak to the Indian Prime Minister, likely to broker a deal focusing on building out Tesla’s presence and bringing new technology to the country.
The road to India has not been without its complexities. Reports confirmed the resignation of Prashanth Menon, Tesla's India head, with oversight of Indian operations temporarily shifting to Tesla's China team. Furthermore, earlier discussions with potential joint venture partners, such as Hyderabad-based Megha Engineering for land acquisition, reportedly did not materialize, leading Tesla to explore other avenues and locations like Satara.
Despite all the setbacks, Tesla’s efforts indicate that they are more determined than ever to make a formal and official entry into the Indian market.
Tesla’s software updates often contain far more than the release notes show, whether they’re undocumented features or preparation for the next big thing. The 2025 Spring Update is no exception - it’s filled with undocumented changes and, of course, new, inaccessible code that points to upcoming features.
Tesla hacker greentheonly on X has been digging into update 2025.14 and found some intriguing additions and hints about what’s coming next, so let’s take a look.
Grok Incoming
New hidden UI elements have been found pointing towards the integration of a Grok-powered smart assistant for Teslas. This includes references to a “personality” button, just like the Grok app. Tesla is likely hard at work on an advanced conversational AI and integrating the ability to control your vehicle.
Grok is the smart assistant that’s expected to replace the ancient voice commands that are available today. However, expect anything beyond vehicle commands to require Tesla’s Premium Connectivity.
While none of these new elements are active just yet, it is a good indication that it is likely on its way quite soon.
Siren Detection UI Removed
Code related to user-facing elements for siren detection has now been removed. We’ve confirmed that the orange dot is still in place with the Spring Update, but elements related to future changes and a UI for siren detection have since been removed from the code base.
Removals don’t indicate much - Tesla could be refactoring the code while they’re working on this or have changed directions on how to implement a future.
Insights into the New Dashcam Viewer
More significantly, for users on HW3, Green reported that the newly improved Dashcam Viewer isn’t just an improved version of the video viewer, but it was built from the ground up, and it’s now web-based. This technical detail explains why the updated viewer is only rolling out to AMD Ryzen vehicles and not older, Intel-based vehicles. HTML-based apps are often quicker to develop but usually require more resources to perform smoothly, which may be why we’re seeing the Ryzen infotainment system requirement.
This likely means that the new Dashcam Viewer won’t arrive on Intel vehicles in a future update unless Tesla can optimize the viewer enough to perform adequately on the older hardware.
HW3 vehicles already missed out on the new B-pillar recording feature. While Green thinks it’s technically possible to bring this feature to HW3 cars, unknown technical issues are likely preventing it. Older HW3 vehicles without a USB port in the glovebox only include USB 2 ports, limiting bandwidth, which could be one of the reasons, among others.
New Key Types
Perhaps a hint at Tesla’s third-party Robotaxi fleet ambitions, Tesla is building out new types of keys.
Rider Keys: These new keys appear to be designed to allow designated riders to access vehicles that are operating in “fleet mode.” This functionality sounds very much like what will be needed to allow Robotaxi customers to access a vehicle temporarily while they’re being given a ride.
Pre-Delivery Keys: Another new key type found is “pre-delivery.” While we don’t have an exact purpose nailed down quite yet, we’re assuming this could potentially allow new owners limited access to their vehicles for inspection prior to officially accepting delivery.
That’s plenty of interesting stuff found in the 2025 Spring Update - and we’re excited to see even more in just a few short weeks once Tesla launches their Robotaxi network in Austin.
