Tesla is rolling out an exciting opportunity for its customers in the United States and Canada to experience the Full Self-Driving (Supervised) feature for one month, free of charge. Yes, it is called Supervised now and not Beta; read more about that change here.
Tesla owners in the US and Canada can enjoy a free month of FSD (Supervised), provided their vehicles are equipped with either software update version 2024.3.6 or 2024.3.10 which is now rolling out to the masses in North America. This initiative is part of Tesla's effort to introduce users to the advancements in autonomous driving technology, specifically the enhancements in the FSD v12 upgrades.
Recognizing Your Eligibility
Eligibility is straightforward. If you currently do not subscribe to FSD, Tesla will email you to notify you of the free one-month trial offer. Keep an eye on your inbox for an email from Tesla. To be in line for the update and the trial, you need to:
If you’re running Tesla update 2024.2.x or older, then you’ll be eligible to download this latest FSD update. Tesla will automatically push the update to your vehicle when it's your turn. The rollout is happening in substantial batches, so patience is key. For more detailed information on the updates, head to our Tesla's software updates page, which offers comprehensive release notes.
Already a Subscriber?
According to X user David Lindsey, if you currently subscribe to FSD, then you’ll also receive a free month of FSD. In his screenshot, he shows that he has been billed for previous months, but his next charge isn’t until May 11th, completely skipping the April 11th charge.
However, if you purchased FSD for a hefty sum, Tesla isn’t being quite as generous, and there won’t be a credit in your account. While this isn’t surprising, it would be a nice gesture to reward owners who bought FSD with some referral credits, or something similar.
Legacy Model S and Model X Owners
Legacy Model S and Model X vehicles have so far been left without FSD v12 access. However, according to Tesla executive Rohan Patel, an update is on the horizon for these vehicles before the redesign in 2021. These vehicles which account for about 3% of all FSD-eligible vehicles, have distinct hardware and need further training and testing before FSD v12 becomes available. Although Patel stood clear of providing an estimate of when a build would be ready, he confirmed that Tesla's AI team is diligently working to ensure compatibility and safety.
How to Start Your Trial
Once you've received the trial notification over email, there’s no need to subscribe to FSD or activate it in any manner. FSD will instantly become available in your vehicle. Unfortunately for some owners who may be away for work or vacation, you can not postpone the trial and it begins immediately.
Although Tesla has moved away from the FSD Beta wording and it’s now officially called FSD (Supervised), always remember that this feature requires you to be constantly aware of your surroundings and to monitor the vehicle closely. While FSD will navigate, change lanes, and even take turns, it's imperative to stay attentive and cautious—the system is designed to assist, not replace, the driver.
The Full Self-Driving (Supervised) upgrade represents a significant leap forward, transitioning the city-streets driving stack to a single, end-to-end neural network. This evolution from explicit coding to neural-based learning aims to enhance your driving experience significantly.
Tesla's offer of a one-month free FSD trial marks the first time Tesla has offered FSD as a trial. Tesla has previously offered trials for Enhance Autopilot, but not for FSD. Tesla hopes that giving customers this unique opportunity to try out FSD will lead to additional FSD subscriptions, which may help boost Tesla’s expected weaker sales this quarter.

In a new video posted to X, Tesla is showing the progress of its first Lithium Iron Phosphate (LFP) cell manufacturing factory in North America. The facility, located in Sparks, Nevada, will be used to produce LFP battery cells for Megapacks and Powerwall.
However, the implications of this new factory extend beyond Tesla Energy. By on-shoring the production of these cost-effective batteries, Tesla is not only securing its energy supply chain but also opening the door to potentially reintroducing LFP-based vehicles in North America.

The immediate beneficiary of the new Nevada LFP facility is Tesla’s Energy division. LFP chemistry is ideal for stationary storage products like Megapack and Powerwall. It offers a very long life cycle, is extremely thermally stable and safe, and is significantly cheaper to produce than nickel-based batteries, partly because it contains no cobalt.
Until now, Tesla has relied on suppliers like CATL in China for these cells. A dedicated, domestic supply will enable Tesla to dramatically ramp up Megapack production to meet North America’s increasing demand for grid-scale energy. On the other hand, Megafactory Shanghai continues to utilize CATL’s LFP batteries and will support the rest of the world.
Tesla first revealed that they were planning to onshore LFP production in North America at the Q1 2025 Earnings Call, which will help them avoid costs, innovate in new technology, and insulate themselves from geopolitical supply chain risks.
A Potential Return for LFP Vehicles?
Another exciting application for Tesla is what this new factory means for Tesla’s budget-oriented lineup. For years, Tesla has been constrained in its ability to offer LFP-based vehicles in North America. While LFP packs are used in other markets for specific standard-range RWD vehicles, tariffs on important Chinese cells made it difficult to import these cells for use in North America.
With a domestic supply of LFP cells produced in Nevada, this tariff-related barrier will be mostly eliminated, pending the sourcing of lithium from a North American site. This is likely to lead to the reintroduction of LFP-based vehicles to the North American market, possibly in late 2026 or 2027.
An American-made LFP pack could lead to a more affordable base Model 3 or Model Y, or potentially help Tesla cut costs on the next-generation Affordable Model even further. This helps to give customers a lower-cost entry point without sacrificing a lot of range, and with the added benefit of being able to regularly charge to 100%.
Mega Nevada
With Mega Nevada now progressing well, Tesla is in an excellent position to continue iterating on its vertical integration and scaling Megapack and Powerwall—two of Tesla’s fastest-growing businesses—further. There are tons of benefits for consumers in the future as Tesla continues down this path, with more affordable Powerwalls for the home, cheaper electricity prices thanks to grid-forming Megapacks, and cheaper LFP vehicles.
The next major upgrade for Tesla’s in-car experience is pretty much already here - just hiding beneath the surface, awaiting the flick of a switch. According to new details uncovered by Tesla hacker Greentheonly, a fully functional version of the Grok conversational AI assistant is already present in recent firmware builds, just waiting for Tesla to activate it.
The feature, which is currently behind a server-side switch, could be enabled at any time by Tesla for vehicles running update 2025.20 and newer. The findings provide a better picture of what we already learned from Green’s breakdown on Grok last month.
Grok’s Requirements
@greentheonly on X
According to what Green determined from the latest software builds, the foundation for Grok was laid with update 2025.14, with more abilities and functionality added in 2025.20 to flesh it out. He also determined exactly which vehicles will be receiving Grok.
In terms of hardware, any vehicle with a Ryzen-based infotainment computer will receive Grok. This means that vehicles with the older Intel Atom processor will not be supported, at least initially. The underlying Autopilot hardware is not a factor, as Grok’s processing is not done in-vehicle.
Grok will also require premium connectivity or a Wi-Fi connection for the vehicle. At this point, we’re not sure whether Grok in your Tesla will also require you to sign up for SuperGrok, X Premium, or X Premium+, but Tesla is requiring you to sign into your Grok account. It’s just not clear whether the free version of Grok will work, or if you’ll need the premium version.
Grok User Experience
@greentheonly on X
Green also revealed the user interface for Grok for the first time. You’ll find many of the same features from the Grok app, but surprisingly, it looks like it’ll have a dark UI, even if you’re using light mode in your vehicle.
It appears that there will be a Grok app, likely for settings. However, Grok will largely operate in a modal, similar to voice commands, which are displayed near the bottom left corner of the screen.
There’s an on-screen microphone button, as well as drop-down menus for the voice and type of assistant you’d like to use.
Similar to the Grok app currently on mobile devices, you’ll be able to select from a set of voices and then define their personality. The available voices for now are the standard Ara (Upbeat Female), Rex (Calm Male), and Gork (Lazy Male).
There’s also a settings button, which, when expanded, allows you to enable or disable NSFW mode (including swearing and adult topics), as well as a Kids Mode, which will tone Grok down to be suitable for when kids are in the car.

How Grok Will Work (Button / Wake Word)
Users will be able to activate Grok by pressing a button, likely the same one that activates voice commands today. Grok will then remain enabled for the duration of your conversation, allowing you to go back and forth, asking and answering questions. To end your conversation, you’ll press the mic button again.
While it doesn’t appear to use a wake word yet, Green says that some code refers to a wake word, so it’s possible that this could be an option Tesla plans to activate in the future.
Replacing Voice Commands
The most significant implication of Grok’s future integration is in its potential to fully replace the existing and relatively rigid voice command system. Green notes that internally, this feature is part of the car assist module, and that eventually, the plan is for Grok to take over car control functions.
Unlike the current system, which requires specific phrases, a true conversational AI like Grok can understand natural language. This will enable more intuitive requests, completely changing how drivers interact with their car.
Language Support
@Greentheonly/X
Grok will also launch with multi-language support, similar to its current abilities in the Grok app. Green says that it already appears to have support for English and Chinese and one or two other languages.
Release Date
Grok appears ready to go from a vehicle standpoint, but Green wasn’t able to actually test it out. While development appears to be nearly complete in the vehicle, Tesla and xAI may still be working on some server-side changes to better integrate with the vehicle. If they plan for Grok to replace voice commands on day one, then it’ll need to be trained and be able to execute a variety of vehicle commands.
It’s possible Tesla is actively testing Grok or adding server-side changes to replace voice commands. However, it looks like vehicle development is nearly complete and Grok could launch as soon as the next major Tesla update, which is expected to be update 2025.24.
