Tesla CEO Elon Musk has provided some context behind the electric vehicle maker’s rollout strategy for FSD 12.5, a highly-anticipated update to the company’s advanced driver-assist system. As per Musk, FSD 12.5’s initial rollout is currently focused on Model Y units equipped with Hardware 4.0 (HW4).
Tesla FSD 12.5 has started rolling out to its first wave of users, though observations from longtime testers have hinted that Tesla seems to be releasing FSD 12.5 only to vehicles equipped with HW4 for now. One of these testers was longtime FSD user @WholeMarsBlog, who noted that HW3 vehicles do not seem to be receiving FSD 12.5 yet.
In a response to the FSD tester’s post, Elon Musk explained that Tesla is indeed focusing on Model Y units with HW4 for FSD 12.5’s initial release. Once the initial rollout is successful, Musk noted that the release of FSD 12.5 will broaden. He also noted that Teslas with Hardware 3.0 (HW3) will run the same parameter count as vehicles with HW4, though doing so requires extra work to optimize the code.
We are focusing on just Model Y with HW4 for the initial release. Make sure that works well, then broaden.
This has the 5X increase in parameters.

end-to-end on the highway is coming in follow-up 12.5.x releases. So is driver monitoring support for sun glasses.— Ashok Elluswamy (@aelluswamy) July 23, 2024
FSD 12.5 has so far been receiving positive reactions from longtime testers of the advanced driver-assist system, though users have noted that the update seemed to lack some previously teased features, such as the merger of city and highway software stacks and vision monitoring support for drivers wearing sunglasses.
There was a huge focus on improving both safety AND smoothness in this release. One of my personal tests is to not spill an open cup of coffee while on FSD. 12.5 was the first version where I was able to do that for 30 min long drives. https://t.co/C65OSCetjY— Ashok Elluswamy (@aelluswamy) July 23, 2024
As per Tesla Autopilot Director Ashok Elluswamy, these features should be released for FSD 12.5.x releases. He also noted that Tesla focused on safety and smoothness with FSD 12.5. “End-to-end on the highway is coming in follow-up 12.5.x releases. So is driver monitoring support for sunglasses,” the Tesla executive wrote.

Starlink achieves major milestones in 2025 progress report
Starlink wrapped up 2025 with impressive growth, adding more than 4.6 million new active customers and expanding service to 35 additional countries, territories, and markets.
Starlink wrapped up 2025 with impressive growth, adding more than 4.6 million new active customers and expanding service to 35 additional countries, territories, and markets. The company also completed deployment of its first-generation Direct to Cell constellation, launching over 650 satellites in just 18 months to enable cellular connectivity.
SpaceX highlighted Starlink’s impressive 2025 progress in an extensive report.
Key achievements from Starlink’s 2025 Progress
Starlink connected over 4.6 million new customers with high-speed internet while bringing service to 35 more regions worldwide in 2025. Starlink is now connecting 9.2 million people worldwide. The service achieved this just weeks after hitting its 8 million customer milestone.
Starlink is now available in 155 markets, including areas that are unreachable by traditional ISPs. As per SpaceX, Starlink has also provided over 21 million airline passengers and 20 million cruise passengers with reliable high-speed internet connectivity during their travels.
Starlink Direct to Cell
Starlink’s Direct to Cell constellation, more than 650 satellites strong, has already connected over 12 million people at least once, marking a breakthrough in global mobile coverage.
Starlink Direct to Cell is currently rolled out to 22 countries and 6 continents, with over 6 million monthly customers. Starlink Direct to Cell also has 27 MNO partners to date.
“This year, SpaceX completed deployment of the first generation of the Starlink Direct to Cell constellation, with more than 650 satellites launched to low-Earth orbit in just 18 months. Starlink Direct to Cell has connected more than 12 million people, and counting, at least once, providing life-saving connectivity when people need it most,” SpaceX wrote.

Tesla Giga Nevada celebrates production of 6 millionth drive unit
To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo.
Tesla’s Giga Nevada has reached an impressive milestone, producing its 6 millionth drive unit as 2925 came to a close.
To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo.
6 million drive units
The achievement was shared by the official Tesla Manufacturing account on social media platform X. “Congratulations to the Giga Nevada team for producing their 6 millionth Drive Unit!” Tesla wrote.
The photo showed numerous factory workers assembled on the production floor, proudly holding golden balloons that spelled out “6000000″ in front of drive unit assembly stations. Elon Musk gave credit to the Giga Nevada team, writing, “Congrats on 6M drive units!” in a post on X.
Giga Nevada’s essential role
Giga Nevada produces drive units, battery packs, and energy products. The facility has been a cornerstone of Tesla’s scaling since opening, and it was the crucial facility that ultimately enabled Tesla to ramp the Model 3 and Model Y. Even today, it serves as Tesla’s core hub for battery and drivetrain components for vehicles that are produced in the United States.
Giga Nevada is expected to support Tesla’s ambitious 2026 targets, including the launch of vehicles like the Tesla Semi and the Cybercab. Tesla will have a very busy 2026, and based on Giga Nevada’s activities so far, it appears that the facility will be equally busy as well.

Tesla Supercharger network delivers record 6.7 TWh in 2025
The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets.
Tesla’s Supercharger Network had its biggest year ever in 2025, delivering a record 6.7 TWh of electricity to vehicles worldwide.
To celebrate its busy year, the official @TeslaCharging account shared an infographic showing the Supercharger Network’s growth from near-zero in 2012 to this year’s impressive milestone.
Record 6.7 TWh delivered in 2025
The bar chart shows steady Supercharger energy delivery increases since 2012. Based on the graphic, the Supercharger Network started small in the mid-2010s and accelerated sharply after 2019, when the Model 3 was going mainstream.
Each year from 2020 onward showed significantly more energy delivery, with 2025’s four quarters combining for the highest total yet at 6.7 TWh.
This energy powered millions of charging sessions across Tesla’s growing fleet of vehicles worldwide. The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets. This makes the Supercharger Network loved not just by Tesla owners but EV drivers as a whole.
Resilience after Supercharger team changes
2025’s record energy delivery comes despite earlier 2024 layoffs on the Supercharger team, which sparked concerns about the system’s expansion pace. Max de Zegher, Tesla Director of Charging North America, also highlighted that “Outside China, Superchargers delivered more energy than all other fast chargers combined.”
Longtime Tesla owner and FSD tester Whole Mars Catalog noted the achievement as proof of continued momentum post-layoffs. At the time of the Supercharger team’s layoffs in 2024, numerous critics were claiming that Elon Musk was halting the network’s expansion altogether, and that the team only remained because the adults in the room convinced the juvenile CEO to relent.
Such a scenario, at least based on the graphic posted by the Tesla Charging team on X, seems highly implausible.
