Inside Tesla’s ‘tent’-based Model 3 line that set a path to profitability
Tesla attracted more headlines than usual when Elon Musk announced on Twitter that the company is introducing a new Model 3 assembly line inside a sprung structure on the grounds of the Fremont factory. Casually dubbed by Elon Musk as a “tent,” the assembly line, dubbed GA4, played a huge part in pushing Tesla towards profitability in the third quarter.
Tesla’s “tent”-based Model 3 assembly line was featured in Elon Musk’s recent segment on CBS’ 60 Minutes. While speaking with correspondent Leslie Stahl, Musk remarked that the assembly line, which took only three weeks to set up, was responsible for boosting Model 3 production by 50%. That was enough to push the company to reach its self-imposed 5,000 Model 3 per week target in the second quarter.
Elon Musk has noted that Tesla is now at a point when it could produce 5,000 Model 3 per week without any problems. Before the company reached this point, though, it had to pass through a period that Musk personally described as “production hell.” During the second quarter, Tesla struggled to ramp Model 3 output using the vehicle’s two assembly lines inside the Fremont factory itself. When it was evident that this could not be achieved, Tesla did the unexpected — it built a third Model 3 line (GA4) to augment its output.
The construction of the “tent”-based line was lauded by the company’s supporters and criticized heavily by Tesla’s skeptics. Inasmuch as the sprung structure was controversial, though, it worked, and it ultimately helped Tesla address the Model 3’s production problems then. When he announced the promotion of Jerome Guillen as Tesla’s new President of Automotive, Musk stated that GA4 was the brainchild of the longtime problem-solver, who was working as the lead of the Tesla Semi program then. Considering how much GA4 helped Tesla reach its production goals, it is not difficult to speculate that the construction of GA4 was one of the reasons behind Jerome Guillen’s promotion to President of Automotive.
CBS correspondent Leslie Stahl noted during the recent 60 Minutes segment that the “tent”-based Model 3 line, contrary to Elon Musk’s initial plans for a fully-automated car factory, is currently filled with human workers. Musk noted during the segment that “People are way better at dealing with unexpected circumstances than robots,” while sharing a laugh with some workers assembling the Model 3.
Speaking with investors back in 2016, Elon Musk noted that Tesla’s electric car factories will be a “machine that builds the machine.” Musk even shared that the codename for the project is “Alien Dreadnought” — a reference to the hyper-advanced extraterrestrial crafts featured in sci-fi films and literature. The CEO initially estimated the dreadnought to be operational by the end of 2018, though the “production hell” that ensued during the Model 3 ramp forced Elon Musk to admit that over-automation was a mistake. Admitting his miscalculation on Twitter, Musk humbly noted that “humans are underrated.”
If there is one lesson that Tesla learned this year, it is that unorthodox solutions such as its “tent”-based Model 3 line — while a step away from Elon Musk’s original vision — are needed for the company to hit its goals. Using a makeshift production line that’s populated with human workers might not be part of Elon Musk’s “Alien Dreadnought,” but it was exactly what Tesla needed to push towards its manufacturing targets. If any, Tesla’s stellar performance in the third quarter, when it surprised Wall Street and skeptics by posting $6.8 billion in revenue, was made possible in no small part by the “tent”-based Model 3 assembly line.
Ultimately, GA4 could serve as a template for the company’s upcoming electric car production facilities, particularly as Tesla is currently setting the stage for Gigafactory 3, which would produce the Model 3 and Model Y for the local Chinese market. Gigafactory 3 is in an extremely aggressive timetable — one which Wall Street even dubbed as “not feasible.” If Tesla can maintain its open-mindedness and its tendency to adopt out-of-the-box solutions, though, even ambitious projects such as Gigafactory 3 would be more than feasible.

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.
