Tesla's FSD Supervised v1263 Update: A Leap Toward Hardware 3 Optimization

2025-02-04

Tesla has continued to push the boundaries of Full Self-Driving (FSD) technology, with the company’s recent announcements regarding the FSD Supervised v12.6.3 update. During Tesla’s Q4 2024 earnings call, executives confirmed their ongoing commitment to improving Hardware 3 (HW3) and gave insight into how the latest update stacks up against previous versions. While Tesla has already begun rolling out vehicles with AI4 hardware, the company hasn’t abandoned HW3 just yet. The FSD Supervised v12.6.3 update has garnered significant attention, with many Tesla owners praising its enhancements.

FSD Supervised v12.6.3: What’s New?

Tesla owners with Hardware 3 vehicles were eager to test out the newly released FSD Supervised v12.6.3, and feedback has been overwhelmingly positive. Users took to social media to share their experiences, with many describing the update as “unbelievable” and “epic.” One Tesla Model 3 owner highlighted the update’s smoothness and confidence, which they had previously only witnessed on the more advanced FSD Supervised v13. This improvement suggests that Tesla’s FSD team has made significant strides in optimizing the system for older hardware, making the experience far more refined and reliable.

Elon Musk on Hardware

While Tesla’s AI4 computers are already in production, the company’s commitment to HW3 remains strong. Elon Musk shared that Tesla intends to offer free upgrades from Hardware 3 to AI4 for customers who purchased Full Self-Driving capabilities with their vehicles. Despite acknowledging the challenges and difficulties associated with the upgrade process, Musk emphasized that the company is dedicated to ensuring the smooth transition for its customers. This move shows that Tesla is not only focused on enhancing the FSD software but also on making sure its hardware remains relevant as new iterations roll out.

What Undercode Says: A Deep Dive into

Tesla’s recent developments surrounding FSD Supervised v12.6.3 showcase the company’s ability to optimize its Full Self-Driving capabilities even on older hardware like Hardware 3. For Tesla enthusiasts and owners, these updates offer a promising sign that their vehicles won’t be left behind as Tesla moves forward with newer hardware iterations. The noticeable improvements in FSD Supervised v12.6.3 demonstrate that Tesla is still heavily invested in the performance of their older systems.

The fact that Tesla executives referred to v12.6 as a “baby v13” is particularly telling. It implies that while Hardware 3 might be older, Tesla is still actively refining the software, ensuring that the user experience remains top-notch. This approach stands in contrast to many other tech companies, which often prioritize the newest hardware and leave older systems behind. The positive feedback from users also reinforces the idea that Tesla’s optimization efforts are paying off, with many owners commenting on the drastic improvements in smoothness and confidence.

However, the bigger story lies in Elon Musk’s comments about the free Hardware 3 to AI4 upgrade. Musk has always been vocal about the challenges that come with scaling FSD technology, and this statement indicates that Tesla is aware of the difficulties that come with maintaining compatibility across multiple hardware generations. Offering a free upgrade from Hardware 3 to AI4 is a significant move, signaling that Tesla is not leaving its early adopters behind. The announcement also comes at a time when AI4 is poised to make substantial improvements in Tesla’s Full Self-Driving capabilities, making the transition to newer hardware a much-needed step forward.

Yet, it’s clear that the transition will not be without its challenges. Elon Musk himself admitted that the process would be “painful and difficult.” Despite these challenges, the company’s commitment to providing an upgrade to HW3 owners who bought FSD reflects a level of customer dedication that sets Tesla apart in the automotive world. Many other companies would have simply left older hardware behind and focused only on their newest products, but Tesla’s efforts to keep improving HW3 and facilitate the upgrade process show an enduring commitment to its customer base.

This move also serves as a key differentiator for Tesla. While many car manufacturers are still in the early stages of developing autonomous driving systems, Tesla has already achieved a level of performance that rivals competitors. By offering continuous updates and support for both hardware and software, Tesla keeps its vehicles competitive and future-proof.

In the long run,
