Elon Musk explains why Tesla built a tent for its new Model 3 assembly line
Tesla CEO Elon Musk has taken to Twitter to discuss why the company decided to set up its newest assembly line for the Model 3 inside a massive tent on the grounds of the Fremont factory. According to Musk, the tent was the result of time constraints, as the company is attempting to hit a pace equivalent to 5,000 Model 3 per week by the end of Q2 2018.
Needed another general assembly line to reach 5k/week Model 3 production. A new building was impossible, so we built a giant tent in 2 weeks. Tesla team kfa!! Gah, love them so much ♥️🚘💫

What’s even more remarkable was that some of the materials used by the Tesla team in constructing the giant tent were scraps the company had in its warehouses. In a later tweet, Musk noted that the tent-housed new line is actually “way better” than Tesla’s other general assembly line, which cost the company hundreds of millions of dollars.
Overall, Musk appears to be optimistic about Fremont’s giant tent. When asked by one of his Twitter followers if the structure is just a temporary solution to achieve the company’s goal of building 5,000 Model 3 per week, Musk stated that he was not sure if Tesla actually needs a building, considering that the tent was already “pretty sweet.” Musk also mentioned that the Tesla Grohmann line is now in place and operating at Gigafactory 1.
Not sure we actually need a building. This tent is pretty sweet. Tesla Grohmann line is in place at Giga & spooling up now. They super kicked ass too. Heiliger Strohsack!

As for worries that Tesla’s workers at the giant tent in Fremont will be uncomfortable, Musk noted that the massive outdoor structure had a view of the surrounding Bay Area mountains and is actually more comfortable than the buildings of the factory. The Tesla CEO further stated that a media tour would probably be held next week, in order to give recognition to the Tesla team, which has pulled off something “miraculous.”
Tesla’s massive tent in Fremont was first spotted by Tesla enthusiasts earlier this month through online services such as Building Tesla. As could be seen in satellite photos of the site, Tesla’s new Model 3 assembly line was around 900 feet in length as of mid-June. Speculations were abounding then among Tesla enthusiasts about what the structure would be used for.
These speculations were addressed this past weekend, when Elon Musk shared a picture featuring the first Model 3 Performance Dual Motor being rolled off the company’s newest assembly line. As noticed by Tesla supporters and critics alike, the vehicle seemed to have been assembled inside a massive tent.
Tesla’s new assembly line bodes well for the company’s chances of hitting its production goals for the Model 3 this quarter. Since the company began manufacturing the compact electric car, it has so far missed its production targets. During Q1 2018, however, Tesla ended the quarter just short of a few hundred Model 3. Since then, the company has doubled down on its efforts to scale the production of the vehicle. New assembly lines were installed, robots and equipment were flown in from Europe, bottlenecks were addressed, record numbers of new Model 3 VINs were registered, and orders for the Model 3’s next two variants — the Performance and Dual Motor AWD — were opened for reservation holders. As the month ends, Tesla is closer than it has ever gone in attaining its ever-elusive goal of producing 5,000 Model 3 per week.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

OpenAI cites distrust of SpaceX in decision to drop Cursor partnership
OpenAI will cut SpaceX-owned Cursor’s model access in November, citing Musk’s history of broken contracts.
OpenAI, the company behind ChatGPT, announced late Friday that it is ending its partnership with Cursor, cutting off the coding tool’s access to its models on November 12. The move comes two weeks after SpaceX completed its $60 billion acquisition of Cursor’s parent company, Anysphere, folding the popular AI coding assistant into Elon Musk’s growing SpaceXAI division.
In a post on its website, OpenAI said the decision came down to trust, not technology. “We cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” the company wrote. OpenAI pointed to two specific incidents: X, now part of SpaceX, allegedly breaking the terms of an existing OpenAI contract after Musk bought Twitter.
That lawsuit is the backdrop for all of this. Musk cofounded OpenAI in 2015, left the board in 2018, and sued Sam Altman and Greg Brockman in 2024, arguing they abandoned the company’s nonprofit mission for profit. A federal jury sided with OpenAI in May, finding Musk waited too long to sue rather than ruling on the merits of his claims. Musk said at the time he would appeal to the Ninth Circuit, calling the outcome a “calendar technicality” rather than a real judgment.
SpaceX’s interest in Cursor predates that verdict by weeks. The company first struck a deal with Cursor in April, securing an option to acquire it for $60 billion or pay $10 billion for joint development work instead. As Teslarati reported at the time, the logic was straightforward: Cursor was paying retail prices to Anthropic and OpenAI, two of its most direct competitors, every time a developer used its product, while SpaceX had idle capacity on its Colossus supercomputer, roughly the equivalent of a million Nvidia H100 GPUs, that Cursor could use to train its own models instead. SpaceX exercised the option in June, days after its own IPO, and the deal closed in mid-August.
Once it closed, Musk moved fast. On an all-hands call with more than 1,000 Cursor employees, he reportedly told staff that SpaceXAI’s Grok was playing catchup in the AI race, unlike Tesla and SpaceX in their own markets, and singled out Anthropic as the company to catch. Cursor CEO Michael Truell now reports directly to Musk inside SpaceXAI.
Losing OpenAI’s models leaves Cursor leaning harder on Anthropic’s Claude, which has its own compute agreement with SpaceX, and on Cursor’s in-house Composer model, the one SpaceX’s compute was supposed to accelerate in the first place. OpenAI framed the November deadline as maximum notice under its contract, and said it wants to “go above and beyond” to help developers through the transition. Whether Anthropic makes the same call is now the open question in AI coding.
