SpaceX Falcon Heavy spied on the move ahead of test fire
While touring Florida’s Kennedy Space Center by bus earlier this morning (January 8), several spaceflight fans captured SpaceX’s Falcon Heavy rolling out to Pad 39A for the second time ever. Following a basic fit check and photo opportunity at the launch pad in the last week of 2017, the launch vehicle now appears to be prepped and ready for its first wet dress rehearsal (WDR) and static fire test.
If all goes well during the wet dress rehearsal’s propellant loading tests, an admittedly less than guaranteed outcome, then the WDR will likely translate into a momentous occasion for the massive rocket: the first-ever simultaneous ignition of all three of its integrated first stages and their 27 Merlin 1D engines. While relatively unique to SpaceX, the company has made a habit of testing each and every new Falcon 9 first stage with two full-up static fire ignitions, one at McGregor, Texas and the other at the vehicle’s given launch pad. Following the destructive failure of Falcon 9 during a September 2016 static fire test, SpaceX further upped their cautious procedures by removing the payload for all future static fires, lest the customer request that it remain integrated for the sake of time savings.
Unsurprisingly, no customers have since chosen to bypass SpaceX’s new risk-reducing procedures. Falcon Heavy will clearly be a return to older methods, delineated by the clear presence of the second stage and Tesla Roadster payload at its top, although this decision was almost undoubtedly driven by the fact that the payload is in no real way valuable or even important for the “customer,” SpaceX itself. The Tesla Roadster is more or less a stand-in for the traditional boilerplate satellite (read: hunk of dead metal) often launched during the inaugural flights of new rockets. The best recent example is the 2004 inaugural launch of Boeing’s Delta IV Heavy rocket, similar to Falcon Heavy in the sense that it also features a triple-core first stage. Its first launch carried a payload that was quite literally a 6000 kg (13500 lb) piece of metal paired with a number of sensors used to gather vibrational data.

Somewhat fittingly, Delta IV Heavy is aiming to conduct its own launch within the next week or so, providing the East Coast with back to back launches of the world’s two largest operational rockets. Still, as SpaceX and Elon Musk have repeatedly mentioned, Falcon Heavy is far more capable than even Delta IV Heavy: while Falcon Heavy is noticeably shorter, narrower, and thinner than Delta, it weighs almost twice as much and will sport nearly 2.5 times the thrust at liftoff.
Delta IV Heavy’s launches are undoubtedly spectacles to behold, particularly given explosive launch procedures, but the vehicle is entirely expendable, whereas Falcon Heavy will attempt recovery of all three of its first stages, and may eventually allow SpaceX to test technology that will enable second stage recovery, as well.
Falcon Heavy will launch a somewhat livelier version of Delta IV Heavy’s boilerplate mass-simulator with the Tesla Roadster, and the main goal is quite clearly to test the vehicle’s ability to send a payload into a trans-Martian injection (TMI) orbit, albeit likely without an actual injection into orbit around Mars at the other end. Even if the payload is somewhat silly, a successful launch to TMI would be the most literal step yet made by the commercial space company along its path to Mars. If this week’s propellant loading and static fire go as planned, launch will likely follow within a week or so – maybe two weeks given the new and unpredictable nature of testing what is more or less a prototype rocket.

Falcon Heavy can be expected to go vertical at the pad within the next 12-24 hours at most, and static fire will follow soon after. After a highly successful evening photographing the January 7 launch of Falcon 9 with Zuma, Teslarati’s launch photographer Tom Cross will be attempting to photograph the momentous test fire as it happens, and you can follow along live on Teslarati’s Instagram.

Tesla HW4.5 spotted in new Model Y, triggers speculation
Owners taking delivery of recent Model Y builds have identified components labeled “AP45.”
Tesla’s Hardware 4.5 computer appears to have surfaced in newly delivered Model Y vehicles, prompting fresh speculation about an interim upgrade ahead of the company’s upcoming AI5 chip.
Owners taking delivery of recent Model Y builds have identified components labeled “AP45,” suggesting Tesla may have quietly started rolling out revised autonomy hardware.
Hardware 4.5 appears in new Model Y units
The potential Hardware 4.5 sighting was first reported by Model Y owner @Eric5un, who shared details of a Fremont-built 2026 Model Y AWD Premium delivered this January. As per the Model Y owner, the vehicle includes a new front camera housing and a 16-inch center display, along with an Autopilot computer labeled “AP45” and part number 2261336-02-A.
The Tesla owner later explained that he confirmed the part number by briefly pulling down the upper carpet liner below the Model Y’s glovebox. Other owners soon reported similar findings. One Model Y Performance owner noted that their December build also appeared to include Hardware 4.5, while another owner of an Austin-built Model Y Performance reported spotting the same “AP45” hardware.
These sightings suggest that Tesla may already be installing revised FSD computers in its new Model Y batches, despite the company not yet making any formal announcements about Hardware 4.5.
What Hardware 4.5 could represent
Clues about Hardware 4.5 have surfaced previously in Tesla’s Electronic Parts Catalog. As reported by NotATeslaApp, the catalog has listed a component described as “CAR COMPUTER – LEFT HAND DRIVE – PROVISIONED – HARDWARE 4.5.” The component, which features the part number 2261336-S2-A, is priced at $2,300.00.
Longtime Tesla hacker @greentheonly has noted that Tesla software has contained references to a possible three-SoC architecture for some time. Previous generations of Tesla’s FSD computer, including Hardware 3 and Hardware 4, use a dual-SoC design for redundancy. A three-SoC layout could allow for higher inference throughput and improved fault tolerance.
Such an architecture could also serve as a bridge to AI5, Tesla’s next-generation autonomy chip expected to enter production later in 2026. As Tesla’s neural networks grow larger and more computationally demanding, Hardware 4.5 may provide additional headroom for vehicles built before AI5 becomes widely available.

Elon Musk’s Grokipedia is getting cited by OpenAI’s ChatGPT
Some responses generated by OpenAI’s ChatGPT have recently referenced information from Grokipedia.
Some responses generated by OpenAI’s ChatGPT have recently referenced information from Grokipedia, an AI-generated encyclopedia developed by rival xAI, which was founded by Elon Musk. The citations appeared across a limited set of queries.
Reports about the matter were initially reported by The Guardian.
Grokipedia references in ChatGPT
Grokipedia launched in October as part of xAI’s effort to build an alternative to Wikipedia, which has become less centrist over the years. Unlike Wikipedia, which is moderated and edited by humans, Grokipedia is purely AI-powered, allowing it to approach topics with as little bias as possible, at least in theory. This model has also allowed Grokipedia to grow its article base quickly, with recent reports indicating that it has created over 6 million articles, more than 80% of English Wikipedia.
The Guardian reported that ChatGPT cited Grokipedia nine times across responses to more than a dozen user questions during its tests. As per the publication, the Grokipedia citations did not appear when ChatGPT was asked about high-profile or widely documented topics. Instead, Grokipedia was referenced in responses to more obscure historical or biographical claims. The pattern suggested selective use rather than broad reliance on the source, at least for now.
Broader Grokipedia use
The Guardian also noted that Grokipedia citations were not exclusive to ChatGPT. Anthropic’s AI assistant Claude reportedly showed similar references to Grokipedia in some responses, highlighting a broader issue around how large language models identify and weigh publicly available information.
In a statement to The Guardian, an OpenAI spokesperson stated that ChatGPT “aims to draw from a broad range of publicly available sources and viewpoints.” “We apply safety filters to reduce the risk of surfacing links associated with high-severity harms, and ChatGPT clearly shows which sources informed a response through citations,” the spokesperson stated.
Anthropic, for its part, did not respond to a request for comment on the matter. As for xAI, the artificial intelligence startup simply responded with a short comment that stated, “Legacy media lies.”

Tesla Europe builds momentum with expanding FSD demos and regional launches
Needless to say, it appears that Tesla is putting in some serious effort into boosting sales in Europe this year.
Tesla has been notably active across Europe in recent weeks, expanding its Full Self-Driving (Supervised) ride-along program, entering a new market, and showcasing its newest vehicles across multiple regions.
Needless to say, it appears that Tesla is putting in some serious effort into boosting sales in Europe this year.
Tesla Europe recently announced the expansion of its FSD (Supervised) ride-along experiences, inviting the public to experience the system on local roads. Initially available in Italy, France, and Germany when it launched, the program has now expanded to Hungary, Finland, and Spain.
The ride-along program allows participants to ride in the passenger seat and observe how FSD Supervised handles real-world traffic scenarios, including dense urban driving and other challenging conditions. Tesla has positioned the initiative as a way to familiarize European drivers and regulators with the system’s capabilities in everyday use. The program has received positive reviews so far, with many being impressed by FSD’s real-world capabilities.
Tesla also recently launched operations in Slovakia with a pop-up store and multi-day public event in Bratislava, as noted in an EV Wire report. The launch, held from January 16 to 18 at the Eurovea Mall Promenade, featured test drives, vehicle displays, including the Cybertruck, as well as family-focused attractions such as a mini-Tesla racetrack.
Local observers noted that Tesla Optimus was also shown at the event, while the Tesla Owners Slovakia club welcomed the brand with a coordinated light show near the Slovak National Theater. Tesla Europe later shared its appreciation for Slovakia in a post on its official social media account on X, stating, “Thanks, Slovakia, for the amazing last 3 days & for giving us such a warm welcome!”
Tesla’s Slovakia entry follows a familiar pattern used by the company in other European markets. Tesla opened a pop-up store in Bratislava as an initial step, with plans for a permanent showroom and a potential service center at a renovated site previously occupied by a Jeep and Dodge dealership. Tesla has used a similar approach in markets such as Czechia and Lithuania, where permanent facilities followed within a few months of pop-up launches.
Slovakia already has six Supercharging sites totaling 46 Superchargers, including two locations in Bratislava, providing early infrastructure support for Tesla owners. Tesla staff program manager Supratik Saha described the Slovakia launch as a strategic expansion in the heart of the EU, citing the country’s strong automotive manufacturing base and appetite for advanced technology.
Beyond the EU, the company also marked another milestone with the first Cybertruck deliveries in the United Arab Emirates, signaling continued geographic expansion for Tesla’s newest vehicle. Just like Tesla Slovakia, the Cybertruck also received a warm welcome from the UAE’s EV community.
