Elon Musk provided a sneak peek into “Cortex”, Tesla’s new AI training center that has been under construction for quite a while at Giga Texas.
Previously, we saw some shots of the new wing for the massive water-cooled supercomputer cluster at Giga Texas, which was being built at the southern end of the Gigafactory.
AI4 Training
Cortex appears to be the name of the supercomputer cluster, and we can assume that it will be referred to that way from now on. Cortex will primarily focus on exploring and expanding FSD’s performance envelope to include AI4, which will begin to diverge from HW3 sometime soon. Tesla hasn’t yet unlocked the full potential of AI4, as it still runs HW3 in emulation mode, but with a few extra tricks that HW3 doesn’t have access to. These are mostly hardware compiler changes, but they make a significant difference in the speed of processing the AI model.
Tesla intends to continue supporting HW3, but it's already apparent that the FSD model for HW3 is smaller than the model for AI4. However, Ashok Elluswamy, Tesla’s Autopilot program director, expects performance to be similar for the most part.
One other thing that Cortex will likely be tackling is not just FSD in cars – but FSD in Optimus. Optimus uses the same principal technology behind FSD for movement, as well as understanding and learning tasks, so we can expect to see plenty of improvements as Tesla is now getting Cortex online.

What’s most interesting is that this new supercomputer cluster isn’t Tesla’s Dojo Supercomputers. Instead, this Cortex cluster is instead based on Nvidia’s H100 GPUs. Dojo was supposed to be Tesla’s in-house designed and specialized AI GPUs, meant to focus on optimizing FSD.
Dojo isn’t dead – but delayed from the sounds of it. We’re excited to see where Cortex takes Tesla in the future, and when Dojo shows up to join the party.

The road to bringing FSD to Europe has been a long and complex one and filled with regulatory and bureaucratic hurdles. Elon Musk, as well as other members of Tesla’s AI team, have previously voiced their grievances with the regulatory approval process on X.
However, it appears that there is finally some progress in getting things moving with recent changes to upcoming autonomy regulations, but the process still seems slow.
Waiting on the Dutch
Elon commented on X recently, stating that Tesla is waiting for approval from Dutch authorities and then the EU to start rolling out FSD in Europe. Tesla is focusing on acquiring approvals from the Dutch transportation authority, which will provide them with the platform they need to gain broader acceptance in Europe. Outside of the Netherlands, Tesla is also conducting testing in Norway, which provides a couple of avenues for them to obtain national-level approval.
The frustration has been ongoing, with multiple committee meetings bringing up autonomy regulation but always pulling back at the last second before approving anything. The last meeting on Regulation 157, which governs Automated Lane Keeping Systems, concluded with authorities from the UK and Spain requesting additional time to analyze the data before reaching a conclusion.
Tesla, as well as Elon, have motioned several times for owners to reach out to their elected representatives to move the process forward, as it seems that Tesla’s own efforts are being stymied.
This can seem odd, especially since Tesla has previously demoed FSD working exceptionally smoothly on European roads - and just did it again in Rome when they shared the video below on X.

DCAS Phase 3
While the approval process has been slow, Kees Roelandschap pointed out that there may be a different regulatory step that could allow FSD to gain a foothold in Europe.
According to Kees, the European Commission is now taking a new approach to approving ADAS systems under the new DCAS Phase 3 regulations. The Commission is now seeking data from systems currently operational in the United States that can perform System-Initiated Maneuvers and don’t require hands-on intervention for every request.
This is key because those are two of the core functionalities that make FSD so usable, and it also means that there may not be a need to wait years for proper regulations to be written from scratch. Now, the Commission will be looking at real-world data based on existing, deployed technology, which could speed up the process immensely.
What This Means
This new, data-driven regulatory approach could be the path for Tesla to reach its previous target of September for European FSD. While the cogs of bureaucracy are ever slow, sometimes all it takes is a little data to have them turn a bit faster in this case.
Alongside specific countries granting approval for limited field testing with employees, there is some light at the end of the tunnel for FSD in Europe, and hopes are that a release will occur by the end of 2025. With Europe now looking to North America for how FSD is performing, Tesla’s Robotaxi results could also play a role.
Tesla’s marketing has always been relatively unconventional, relying on word-of-mouth rather than traditional advertising. The passion of the owner’s community is always massive, but it is especially high now with the launch of the Robotaxi network just around the corner.
Tesla is now tapping into that spring of fan creativity and announced the TeslaVision video contest, with some seriously impressive prizes up for grabs.
Announcing the TeslaVision fan video showcase
Tesla owners & supporters have always been able to see our products & mission for what they truly are.
Your word of mouth has made Tesla what it is today.
The OGs will remember that in 2017, we held our first video contest. 8 years… pic.twitter.com/6pPpkqmqOH
The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.
Prizes
The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.
For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.
The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.
The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.
For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:
