Tesla files to build EV batteries on new production lines at Fremont Factory
Tesla (NASDAQ: TSLA) has filed to build a new battery manufacturing equipment line at the Fremont Factory in Northern California. The factory, which Tesla purchased in 2010, is the only in the company’s lineup to produce all four models. It has not been known as a battery cell or pack manufacturing plant, as the company’s Gigafactory in Sparks, Nevada, produces those EV components. However, the filings indicate Tesla may be looking to slightly expand its cell manufacturing efforts with new production lines at Fremont.
Filed and signed by Tesla on August 30, the permit is labeled as “Tesla F21-0391-A – CTA Battery B-Build.” Tesla gives the following description of the project:
“NEW BATTERY MANUFACTURING EQUIPMENT LINE ON 2ND FLOOR OF MAIN ASSEMBLY BUILDING. THIS PERMIT APPLICATION RELATES TO THE MODULE PORTION OF THE LINE.”
The project is valued at $1.5 million, according to documents seen by Teslarati.

Additionally, another application reveals a $1.3 million project that includes the installation of a new maintenance office, a storage area, production cells with equipment for hood, fender, and trunk lids, and offline cell manufacturing equipment. This project is listed to be on the first floor of the assembly building.
Interestingly, the Fremont Factory has been one of Tesla’s more spacially-confined facilities. Earlier this year, during a visit from Morgan Stanley analysts, including Adam Jonas, the firm noted the Fremont Factory was incredibly tight in terms of storage capacity and room in general. Despite running at a capacity of 20 percent above what has been considered its maximum. “The plant was never designed to produce 450k units (at its peak produced ~300k units before Tesla took it over from Toyota), which was immediately apparent at the tour, ” Jonas wrote in his note describing the visit. “Tesla does not shy away from the fact the plant is inefficiently designed with four assembly buildings, one of which is a tent that cars are assembled in,” referring to GA 4.5, which was made permanent last year.
Just two weeks prior to Morgan Stanley’s visit to Fremont, CEO Elon Musk stated Tesla was considering expanding Fremont “significantly.” While many of us just thought this likely meant an expansion of vehicle production alone, Musk may have been hinting toward an expansion of the manufacturing process altogether.
Tesla battery manufacturing efforts
Tesla has held battery supply deals with Panasonic, CATL, and LG Chem, but has also started building its own cells in-house. In 2020, Tesla unveiled its 4680 battery cell, which has already been prototype-tested by Panasonic. Tesla has been building the cell at the Kato Rd. facility just a few blocks away from Fremont’s front doors. However, the automaker has not scaled this cell to mass production as of yet, and Tesla could always use more battery cells.
With the 4680 cell not quite reaching mass production volumes yet, an order log that grows with what seems to be every minute, and a production volume that just simply has not caught up to Tesla’s demand, it would make sense to expand in-house battery manufacturing efforts as supplementary support.
“I think we’ve said this now for many years. I know has proven true. Tesla does not have a demand problem, we have a production problem. And we’ve almost always had it’s a very rare exception it’s always been a production problem,” Musk said after Q2. “I think that will remain the case.”
Rearranging at the Fremont Factory
Over the past month or so, Tesla has filed to make many significant changes at the Fremont Factory. After we reported on the construction efforts that are seemingly underway, Tesla has also been filing several applications with the City of Fremont for equipment repositioning, as well as the construction of new foundations and manufacturing equipment. Even things as simple as light poles are being repositioned to make way for potential new manufacturing buildings.

Tesla has also started relocating Model S and X production equipment to other portions of the factory. “GASX,” which we can assume is “General Assembly Model S and X,” has had a hoist relocated, according to filings. Tesla has also filed to install production tools and other associated Model S and Model X manufacturing utilities in the factory. This does not necessarily imply that production lines for the two vehicles will be expanding, especially considering the vehicles make up an extremely small portion of Tesla’s overall sales. However, these manufacturing lines may be shifting to other locations at Fremont to make way for the perhaps imminent installation of cell manufacturing lines at Fremont.

Tesla Optimus Gen 3 shows off a cleaner, factory-ready design in new app discovery
Renders hidden inside Tesla’s Android app show Optimus Gen 3’s design before any official reveal.
Tesla may have accidentally given a first look at its newest Optimus Gen 3 humanoid robot when photos were found in the Tesla smartphone app.
Design files tucked inside a recent Android version of the Tesla app appear to show the third generation humanoid robot next to the older Gen 2.5 prototype. The assets were extracted from the app package by Tesla community member @wholemars, who posted the renders on X late Tuesday night before deleting them. The Tesla Newswire reshared the side by side comparison on Wednesday, and the images have circulated widely since.

Tesla Optimus Gen 2.5 vs Gen 3 comparison via @WholeMars on X
The files are labeled “gen3” and were built as models for Tesla app’s own interface, as validated directly by Grok to be official.
The comparison shows a robot that looks built for a factory line rather than a lab bench. Gen 2.5’s exposed mechanical linkages and gold plating on the knees and shins are gone. In their place, Gen 3 uses matte black fairings on the lower legs, paired with a more contoured champagne gold body. Flexible covers now seal the joint where the torso meets the upper thighs, keeping bearings and moving parts sealed from debris and unnecessary contact.
The body panels fit more tightly, and the hands, which Tesla has said carry 22 degrees of freedom, look far more refined than those on earlier units.
This most recent leak fills a gap Tesla has left open for most of the year. Elon Musk said on March 31 that Optimus 3 was walking around but needed “some finishing touches” before it could be shown, a delay Teslarati covered when Tesla missed its first quarter reveal target. Musk later said Tesla would hold the design back until closer to production, partly to keep competitors from copying it. No reveal date has been announced.
The app itself has been preparing for Optimus for months. In July, code in the Tesla app pointed to a dedicated robot phone key, a consent screen for collecting video and spatial data while Optimus works inside a home, and an alert system for low battery and mechanical faults. Finished 3D models of Gen 3 suggest the interface owners will eventually use is moving past placeholder code toward something Tesla intends to ship.
Manufacturing is moving in parallel. Tesla tore out the original Model S and Model X lines at Fremont this summer to make room for Optimus production, with a planned capacity of one million robots a year. At Giga Texas, the steel frame of a dedicated Optimus factory is nearing completion ahead of a targeted 2027 start, with Musk pointing to an eventual output of 10 million units annually.

X changed how everyone gets paid, and this lawsuit shows why
X sued a Bitcoin account network over fake payouts as its creator pay model shifts
Elon Musk’s X has taken a Bitcoin-focused engagement ring to court, and the case doubles as a receipt for how differently the platform pays creators today. The company filed suit in the High Court of England and Wales against Vivek Kumar Sen and Zamyang Sherpa, alleging the pair ran six accounts, including @Vivek4real_, @Bitcoin_Teddy and @TrendingBitcoin, as one coordinated operation to fake the kind of engagement that used to translate directly into money.
According to the filing, first reported by Gizmodo, the accounts posted near identical “BREAKING” crypto headlines seconds apart, in one case 11 seconds, then had three more handles like, reply to and repost the material to manufacture what X called “a false appearance of genuine, human communication and interaction.” X says the scheme pulled in at least £207,384, about $278,000, and pegs its own investigation and remediation costs at another £75,000. The accounts were suspended August 18. X general counsel James Burnham announced the case on X last weekend, writing that the company “will act forcefully to protect our platform and the earnings of genuine creators.” Musk’s own reaction, posted shortly after, was three words: “Don’t mess with 𝕏.”
Don’t mess with 𝕏 https://t.co/HSmd5hL6aQ
— Elon Musk (@elonmusk) September 21, 2026
The timing lines up with a a recent update to how X pays its creators. The program these accounts allegedly gamed, Creator Revenue Sharing, launched in mid 2023 and paid out based on how much a post got engaged with. Originality was never part of the formula, which is exactly how the platform ended up flooded with recycled clips, copy pasted “BREAKING” posts and replies engineered purely to farm reactions from paying subscribers.
X tried patching the model more than once, including an April cut to aggregator payouts and a March regional weighting change that Musk personally paused hours after it was announced. X retired Creator Revenue Sharing for good on September 7 and opened its replacement, Original Content Rewards, the next day.
Today, we’re launching Original Content Rewards.
The reality is that Revenue Sharing had reached a point where its incentives were misaligned. Creators should be focused on bringing net new content to the platform instead of maximizing payouts. We could have kept adding more… pic.twitter.com/VJIxqlPrjm

The new math is stricter. Payouts now come only from qualified impressions, meaning unique Home Timeline views from Premium subscribers where at least half the post is visible, and replies no longer count toward eligibility at all. Copied posts, reuploaded media and reposts without meaningful changes are explicitly excluded. Allegra Jacchia, senior product manager for Creators at SpaceXAI, which now runs X’s product and AI work following xAI’s acquisition of the platform, put it bluntly, saying the goal is to reward creators who bring original ideas and perspective, “not those who have become best at gaming the system.”
Read that way, the lawsuit isn’t really about six crypto accounts. It’s X putting a dollar figure on what the old incentive structure cost, then suing to collect it right as the new one goes live. For live updates on how the case and the new rewards program shake out, follow @Teslarati on X.

Why automakers keep turning down Elon Musk’s Tesla Full Self-Driving offer
Elon Musk confirms no automaker has ever accepted Tesla’s offer to license Full Self-Driving software.
Elon Musk gave a brief answer on X Monday that confirmed that Tesla’s standing offer to license Full Self-Driving to other automakers still has zero takers. Sawyer Merritt wrote that “Tesla has for years openly invited other automakers to license FSD. None of them have accepted,” responding to a prediction from Boom Supersonic founder Blake Scholl that Tesla would eventually open FSD the way it opened its Supercharger network to rival brands. Musk’s reply to Merritt was one word: “Exactly.”
It is not the first time Musk has made this point. He said something similar in November, when he called legacy automakers reluctance to adopt FSD “crazy,” and Tesla has floated the offer publicly since at least 2021. Scholl’s prediction touches on something real. Once NACS became the de facto charging standard, adoption from Ford, GM, Rivian and others followed within about a year. FSD licensing was supposed to work the same way once Tesla built enough of a lead that switching made sense for everyone.

— Sawyer Merritt (@SawyerMerritt) September 22, 2026
The case for licensing now is stronger than it was two years ago. Waymo and Zoox are logging hundreds of thousands of unsupervised autonomous miles, along with Tesla’s own Robotaxi fleet. Every automaker still selling driver assist systems that lag FSD has given the robotaxi conversation to Tesla, Waymo and Zoox by default. Licensing FSD would let a GM or a Ford compete on the same field without spending a decade and billions of dollars building a stack from scratch, the same argument Tesla made when it opened the Supercharger network to bring more EVs onto its chargers.
But FSD is not a connector standard. As one reply to Musk’s post pointed out, licensing FSD is not a software license the way NACS was a plug spec. It requires adopting Tesla’s eight camera layout and its onboard compute architecture, meaning a licensee’s cars would effectively become Tesla hardware wearing someone else’s badge. That is the visible obstacle. The less visible one is data. A licensed FSD stack would report back the same telemetry Tesla collects from its own fleet, giving Tesla a continuous read on how a competitor’s cars are actually driven, where they struggle, and how often drivers intervene. For an automaker trying to build its own autonomy program, or simply trying to keep its build quality and safety record private, handing Tesla that visibility could be a bigger cost than the hardware bill. It is the reason the Supercharger comparison only goes so far. Opening a charging plug cost Tesla very little. Opening FSD would cost a rival something it cannot get back.
