Tesla was aiming to have the beta initially available this weekend, but after releasing the beta to employees, Tesla wanted to make some changes before releasing it publicly.
Tesla employees were initially given release 2021.36.8.7, followed by 2021.36.8.8 the following day.
It's not clear what the issue was, or what Tesla fixed, but the release notes for both versions are the same and the FSD Beta version number didn't change between them as the beta remains at v10.5.
98 Safety Scores
With this release Tesla is also hoping to expand the beta to owners who have achieved a Safety Score of 98 or higher.
It appears that that is still the plan as we haven't heard otherwise as of yet, but it doesn't appear that the expansion has started yet.
It's likely that Tesla is completing the rollout to all existing beta testers and will wait a few days before expanding it to additional testers.
Release Notes
Tesla has once again posted technical release notes for the beta. It doesn't appear to have any new functionality, but instead improving various key aspects of what it already does such as better object detection and maneuvering.
The full technical release notes are below:
- Improved VRU (pedestrians, bicyclists, motorcycles) crossing velocity error by 20% from improved quality in our auto-labeling.
- Improved static world predictions (road lines, edges, and lane connectivity) by up to 13% using a new static world auto-labeler and adding 165K auto-labeled videos.
- Improved cone and sign detections by upreving the generalized static object network with 15K more video clips and adjusting oversampling and overweighting strategies (+ 4.5% precision, + 10.4% recall).
- Improved cut-in detection network by 5.5% to help reduce false slowdowns.
- Enabled "emergency collision avoidance maneuvering" in shadow mode
- Enabled behavior to lane change away from merges when safe to do so.
- Improved merge object detection recall by using multi-modal object prediction at intersections.
- Improved control for merges by increasing smoothness of arrival time constraints and considering possible merging objects beyond visibility.
- Improved lane changes by allowing larger deceleration limit in short-deadline situations.
- Improved lateral control for creeping forward to get more visibility.
- Improved modeling of road boundaries on high curvature roads for finer maneuvers.
- Improved logic to stay on-route and avoid unnecessary detours/rerouting.
The full release notes for this beta are accessible on our release notes page.
New Terms
The FSD Beta will also require you to reapprove the terms of use, which will require you to go into Controls > Autopilot before you can use FSD.
The terms appear to be the same as the previous beta, so it's not clear whether Tesla will be updating the terms or if this will be a new policy where you will have to accept the terms with each beta release.
It does serve as a reminder that this is still very much beta software and you need to be vigilant when using it.
First Look
The first videos of beta 10.5 are now becoming available. Here are some of the first videos below.
In this first video DirtyTesla tries the beta around some major construction.
Visualizations
We haven't noticed any new object visualizations yet, but the visualizations for road lines and road edges appear to be much improved.
Previously when the car wasn't sure exactly where a line or edge was, it could cause excessive blurring or jitteriness where the line would shift back and forth.
In this release the lines appear much more consistent and do not bounce back and forth as much as they did in previous releases.
The improved visualizations can be seen in this James Locke video where he takes the beta through his test loop 1. James has consistently tested previous betas through various loops so that we can see their progress over time.

For Tesla owners with vehicles equipped with Hardware 3 (HW3)—once hailed as the key to unlocking autonomy, Robotaxi functionality, and unsupervised Full Self-Driving—the landscape is quickly changing. FSD updates were previously available for HW3 and HW4, but now, HW3 is often excluded from newer FSD updates due to compute and memory constraints. While HW3 vehicles still run a capable version of FSD, they are considerably less smooth than HW4 vehicles.
This has many HW3 owners curious about Tesla’s plans to upgrade these older vehicles, which were once promised to be capable of true autonomy. Let’s take a look at everything Tesla has said and what we should expect.
The HW3 Predicament
Introduced around April 2019, HW3 was a big leap over HW 2.5 and HW 2, with Tesla billing it as the computer that would eventually deliver true self-driving. For a long time, it powered the FSD Beta program. However, as FSD Supervised becomes more complex and data-intensive, particularly with neural networks moving towards an end-to-end AI approach, questions about HW3’s long-term lifespan have grown.
While HW3 vehicles are still receiving FSD updates, with the latest version, V12.6, launching in January 2025, the latest improvements in FSD v13 appear to be stretching even the more modern capabilities of AI4 hardware. This has understandably led to concerns that HW3 will not support Robotaxis and true autonomy.
Tesla’s HW3 Upgrade Promise
To address these concerns, Elon Musk has made increasingly definitive statements. After initially suggesting an upgrade would happen "if needed," he confirmed at the Q4 2025 Earnings Call that Tesla will upgrade HW3 computers for customers who purchased the FSD package.
Musk stated, “That's going to be painful and difficult, but we'll get it done. Now I'm kinda glad that not that many people bought the FSD package, haha.”
While Musk initially stated that Tesla would offer a hardware upgrade if needed, he gave more details this time, stating that the complimentary upgrade would be available for those who purchased the FSD package. Subscribers and non-subscribers will likely need to pay a fee similar to the HW 2 / HW 2.5 upgrade. Interestingly, Tesla was later sued for charging a fee to upgrade to HW3 and had to waive the cost.
When Will the HW3 Upgrade Be Available?
Despite Musk’s confirmation of an upgrade, Tesla hasn’t provided any timelines or estimates for HW3 retrofits. The prevailing logic, and one that aligns with Tesla’s approach to engineering challenges, is that the company is unlikely to initiate a mass upgrade program until FSD is significantly closer to being “solved,” meaning it has achieved true, unsupervised autonomy where a driver is not needed.
Until Tesla knows the final, stable computing power and architectural requirements needed for that level of autonomy, rolling out an interim upgrade wouldn’t make sense. It would risk needing yet another upgrade down the line. Therefore, HW3 owners are in a waiting game - will they wait it out, or will they take one of Tesla’s FSD transfer deals?
What to Expect With the HW3 Upgrade
One thing is clear. The upgrade will not be a simple swap to the current generation of HW4 hardware. AI4, as found in newer Tesla vehicles, has different physical dimensions, power and cooling requirements, and connector configurations that make it incompatible as a direct retrofit into HW3-designed vehicles. It’d require a lot of effort and cost to adapt HW4 for HW3 vehicles.
This means Tesla will have to develop another custom-designed retrofit FSD computer specifically for HW3 replacements. This computer must fit within an existing and defined physical space and operate within the power and cooling budget of older vehicles.
Speculation naturally turns to Tesla’s next-generation FSD hardware, HW5 or AI5. Elon previously indicated that AI5 would appear in new vehicles near the end of 2025, initially citing a timeframe of 12-18 months back in mid-2023. However, it now looks like it’ll ship sometime in the first half of 2026.
Potentially, a variant of this new AI5 computer, perhaps a more power-efficient or underclocked version, could be engineered to form the basis of the HW3 retrofit solution. This is plausible, as newer chip architectures often bring considerably greater efficiency, potentially allowing a more powerful new design to operate within HW3’s constraints.
What About HW4 and HW5?
The current-generation FSD computer, HW4, is already facing some constraints with the latest FSD v13 updates. This means buyers and owners of AI4 vehicles are also starting to have this question creep into the back of their heads… “What about my vehicle?”
Based on Tesla’s official statements on AI5, it is poised to be a powerhouse of an upgrade. That means up to 10 times the processing capability of AI4. This is an immense increase in processing power, and over time, Tesla will likely use every bit of it to make FSD handle as many edge cases as possible. While AI4’s computing power was a modest increase from HW3, the leap from AI4 to AI5 is expected to be significantly larger.
Tesla’s executive team has stated that the existing cameras on HW3-equipped vehicles are “capable” and that the upgrade will be focused on the FSD computer. While the AI4 cameras offer a much higher resolution than HW3, Tesla says they’re not needed. This appears to contradict what Tesla is doing as of FSD v13.2. In that update, Tesla introduced processing FSD camera feeds at full resolution, suggesting that there is some advantage to the higher-resolution cameras.
Musk also stated that cameras would not be upgraded in HW3 vehicles.
As we’ve previously covered, the newer HW4 cameras offer several advantages over the HW3 camera generation, which include:
Higher Resolution: The AI4 cameras feature 5 megapixels, compared to the 1.2 megapixels on HW3 cameras, which allows the vehicle to see things further away and in sharper detail.
Improved Dynamic Range and Low-Light Performance: The improved dynamic range allows the system to see more clearly in low-light conditions, such as during sunrise or sunset, or at night.
Wider Field of View: The rear camera on AI4 features a significantly larger field of view, providing greater awareness of the vehicle's surroundings.
It's known that AI4 processes camera data at these higher resolutions, which undoubtedly contributes to its increased performance in decision-making, object recognition (especially at a distance or for small details, such as text on signs), and overall FSD smoothness.
Therefore, while a new, more powerful retrofit computer for HW3 vehicles will bring substantial improvements, it will still be processing input from the older-generation cameras. Another technical challenge that Tesla will need to address is how to maximize FSD performance using the existing HW3 cameras.
Infotainment (MCU) Upgrade?
Most HW3-era vehicles are equipped with the older Intel Atom-based infotainment computer, known as MCU 2. Newer Teslas, as well as newer HW3 vehicles, use the considerably faster AMD Ryzen-based MCU 3. Given that Tesla sometimes packages the FSD computer and infotainment computer together, it wouldn’t be too surprising to see an MCU upgrade as part of an FSD computer retrofit.
While this would be a welcome improvement, providing a snappier user interface and better media capabilities, Tesla has not confirmed any such plans. The FSD computer and the MCU are technically separate systems, but Tesla usually bundles them together to save on costs. While Tesla has offered paid MCU upgrades in the past (e.g., from the older MCU 1 to MCU 2), there is currently no official upgrade path from MCU 2 to MCU 3.
It’s best to assume that the promised free FSD computer upgrade will not automatically include an infotainment system upgrade as well, but it’s certainly possible, given that Tesla usually bundles these together.
Playing the Waiting Game
For Tesla owners who purchased FSD with their HW3 vehicles, the commitment for a free hardware upgrade is on the record. However, the "when" and "what" remain tied to the challenge of achieving true, unsupervised autonomy. Once Tesla understands the compute power required to solve FSD, we’ll likely hear more about this hardware upgrade. Until then, we’ll have to hold on tight with FSD v12.6.
In just 8 months, Tesla has gone from breaking ground to delivering electrons at its most ambitious Supercharger project to date, just in time to be ready for the busy Fourth of July holiday weekend. Project Oasis, the world’s largest Supercharger site, is now partially open to customers for its first phase in Lost Hills, California.
What makes this remarkable is the speed of execution. In just eight months, Tesla has constructed a site that will eventually feature 168 stalls (84 stalls are now open), supported by 11 MW of solar power and 10 Megapacks of battery storage. That construction speed is pretty impressive, but what is even more impressive is how this new station operates and what it means for future Supercharging infrastructure.
Self-Sufficient Energy Oasis
Not a Tesla App
The first 84 stalls at Lost Hills are now open, and according to the Tesla Charging team, they are currently powered solely by the sun and operate off-grid.
This makes it more than just a new Supercharger site. It serves as a proof of concept for a new type of Supercharger. Unlike nearly every other charging site in the world, which draws power from local utilities, this station generates its own clean electricity from its massive solar array and stores it in its array of on-site Megapacks.
Self-sufficient charging stations are something completely different than what we see today. They are highly resilient since they’re not reliant on the grid. That means that even if there is a local power outage, brownout, or blackout, one can always come to Lost Hills to Supercharge.
If you’ve got a Cybertruck, you could take advantage of the Cybertruck’s Powershare feature and charge up at Lost Hills to help keep your home powered during a blackout, utilizing the Cybertruck as a portable battery charger. Now that’s true independence and self-reliance.
The Future of Charging
Solar-powered Superchargers help avoid massive new loads on already stressed electrical grids, especially during peak afternoon and evening hours, when demand is the highest.
This is Tesla’s vision for the future of charging: a clean, fully closed-loop ecosystem that sustains itself. The sun’s energy is captured, stored, and delivered directly to vehicles on site at any time of day without relying on the electrical grid or fossil fuels.
Largest Supercharger in the World
This opening of 84 stalls is just the first phase of the project. Tesla says that the remaining stalls, as well as a new on-site lounge, are coming later this year. Once complete, the 168-stall site will be the largest Supercharger site in the world.
While the speed of building such a massive project in just eight months is a testament to Tesla’s execution, the true innovation is actually that self-sustainability. Let’s hope we see even more large, self-sufficient Supercharger sites across the world in the near future.
