Tesla’s 4680 Kato Rd. facility has a top 10 capacity, and it’s not even close to finished
Tesla CEO Elon Musk disclosed some details about the electric automaker’s 4680 cell plant last week. After stating that the facility is “probably in the top 10 battery cell factories on Earth despite being a pilot plant,” speculation began about how massive Tesla’s new facility that sits just across the street from the Fremont production facility is. Although it is in the top 10, it’s not even close to finished.
Tesla’s introduction of the 4680 battery cell came in September 2020 at the Battery Day event. Musk and others outlined the company’s roadmap for global EV dominance through the most important part of an electric car: the cell. The new cell has 500% more energy, six times the power of the old 2170 cells, and also offers dramatic range increases for more drive time between charges. It was truly revolutionary because Tesla is already the most notable company in electric cars.
With a considerable lead in the EV sector, Tesla was effectively announcing, “eat our (sustainable) dust” after showing the new 4680 cells. Some were skeptical, believing that the new cell wouldn’t be available for some time. Musk immediately silenced those doubts, indicating that the new cells had been deployed in working vehicles for months.

The point is, the Kato Road facility, as it is widely known as, is one of the largest facilities in the world. While we are not sure what the current capacity is, if it is a top 10 facility in terms of capacity, we can speculate how big it may be.
According to Argus Media, the 10 largest battery cell plants range from 24 GWh per year to 70 GWh per year. The largest, an LG Chem facility in Wroclaw, Poland, has the 70 GWh capacity, leading BYD’s Qinghai, China plant by 10 GWh. Tesla and Panasonic’s joint venture at Gigafactory 1 in Nevada is a 35 GWh per year facility, making it the fifth-largest plant globally.

Because Tesla’s Kato Road facility is a pilot plant, we can likely assume that it is within the bottom half of this list. Especially with Gigafactory 1 being the fifth-largest, it is very likely that Kato Road is simply not producing as many cells or as much battery capacity as Giga 1, but it’s not to say that this won’t happen. The issue is that Tesla is still battery constrained, even with a large-scale facility in Nevada and with several third-party manufacturers pumping cells to the automaker at a massive rate. Kato Road will contribute to the solution to the constrained problem, and the facility will likely be significantly larger than Giga 1, considering the projects that Tesla plans to fulfill with the 4680 cells, the largest being the Tesla Semi.
The Semi is still not ready for production, Musk said on the Q4 Earnings Call last week. “We will have cells group in ourselves for Semi when we were producing the 4680 volume. But for example, Semi would use typically five times the number of cells that a car would use, but it would not sell for five times what a car would sell for. So it kind of doesn’t make…it would not make sense for us to do the Semi right now,” Musk said. The issue is cell availability, and since the Semi is going to equip Tesla’s newest 4680 project, it is safe to assume that Kato Road still has some expanding to do. If it is already a top 10 facility, yet it is still not ready to take on the massive Semi task, along with all of the other vehicles it will eventually fulfill, Kato Road may become a top 3 facility.
Ultimately, Tesla requires more cells. With no plans to eliminate purchases from third-party suppliers in the near-term, Tesla wants to increase purchases from those suppliers. CATL, Panasonic, and LG Chem could supply Tesla with more batteries moving forward, even with the Kato Road facility’s expansion and ramping up. The fact is, Tesla isn’t done solving the battery constraint issue, and it could battle with it for years to come. However, it won’t stop production from increasing because more cells are becoming available almost every day through supplier deals, increased outputs, and in-house manufacturing advancements, all of which make Tesla the company to beat for the foreseeable future.
Tesla just upgraded its headlights through a software update, making them even better without any physical or hardware upgrade.
Tesla’s latest software update is quietly improving nighttime driving for a small number of owners. Version 2026.38 includes a new capability called Dynamic Headlight Leveling.
The feature automatically adjusts the aim of the low beams in response to driving conditions and nearby traffic, with the goal of giving the driver more usable light on the road while reducing glare for oncoming vehicles and traffic ahead.

Model 3 gets Dynamic Headlight Leveling — low beams auto-aim around traffic for max visibility, less glare. Model 3 / Y (AMD HW3) also pick up sharper Tesla visuals + an enhanced park scene on the center display.

Unlike Tesla’s matrix high-beam system, which selectively dims individual LED segments to create shadows around other cars, Dynamic Headlight Leveling physically tilts the low-beam projectors. Internal motors respond to changes in vehicle pitch.
When the car accelerates hard, climbs a steep grade, or carries extra weight in the rear, the headlights can otherwise point higher than intended. The software counters that movement in real time so the beam stays aimed at the road surface rather than into the eyes of other drivers.
Early indications reveal the update is reaching a limited set of vehicles, including certain Model 3 and Cybertruck examples in the United States and the United Arab Emirates. The rollout does not appear tied to a single hardware revision, and Tesla has not published a broader schedule. It is simply a common waiting game until your car receives it.
The change arrives against a backdrop of wider complaints about headlight glare. Some earlier Model 3 and Model Y vehicles were the subject of an NHTSA recall related to excessive low-beam glare; the software adjustment offers a potential mitigation for cars equipped with the necessary leveling hardware. It does not replace adaptive high beams where those are already available, nor does it alter the basic low-beam pattern itself.
Instead, it keeps an existing beam pointed where it is most useful.
For drivers who have received the update, the system requires no new settings or user input. The headlights simply respond as road conditions and traffic change. As the feature reaches more vehicles, it adds another example of Tesla using over-the-air software to refine existing hardware rather than waiting for a new model year. Nighttime visibility and reduced glare for others are the practical results owners are expected to notice first.

Tesla teases “Halloween Mode” update with Optimus rising from a graveyard
Tesla’s Halloween teaser hides a covered vehicle and an Optimus hand rising from the ground.
Tesla has started teasing a Halloween software update for its vehicles, with a short clip on X that reads, “Halloween is coming.” The clip opens on a glowing pumpkin before pulling back to the car’s center touchscreen, where the usual parked visualization has been replaced by a graveyard scene, and the vehicle draped with a white sheet so it reads as a cartoon ghost.

The second detail is a robotic hand clawing its way out of the dirt like a zombie, which looks to be the hand of Tesla’s latest Optimus V3 humanoid robot. While Tesla still has not formally shown Optimus Gen 3 walking around in service, renders pulled from Tesla’s Android app last month gave the clearest look yet, including far more refined hands that Tesla has said carry 22 degrees of freedom. The hand has been the hardest part of the program. Musk has called it the majority of the robot’s engineering difficulty, and Tesla’s patents describe a design driven by tendons with the actuators moved into the forearm.

Optimus also has a Halloween track record. Last October the robot handed out candy in Times Square, and a costumed “zombie” Optimus shuffled around the Tesla Diner in Los Angeles on Halloween night.
On the software side, Tesla’s 2025 Holiday Update expanded Santa Mode with a Santa sleigh, snowmen, snow effects, and a festive lock chime, so it wouldn’t be too far fetched if we saw something similar but themed for a Halloween Mode.
Tesla Full Self-Driving is set to receive improvements to address its two biggest issues, according to a company engineer.
Director of Engineering at Tesla AI, Phil Duan, revealed in a post on X that improvements to both pothole avoidance and navigation “are coming,’ something we have heard many times in the past. However, there are a few things that seem to hint that things might be different this time around.
Improvements on both are coming.

Pothole avoidance, navigation, speed control, and left lane camping are some of the most prevalent and frequently mentioned shortcomings of the Full Self-Driving suite. These are a few of the biggest issues that have kept Tesla Full Self-Driving as a Supervised suite, meaning drivers must remain attentive during operation.
Pothole Avoidance
Pothole avoidance was first mentioned as an “Upcoming Improvement” with the Tesla Full Self-Driving v14.3 update back in early April of this year. It was listed alongside “Expand reasoning to all behaviors beyond destination handling.”
It’s been six months since we first saw pothole avoidance explicitly mentioned, and it has not moved beyond that and joined the main release notes yet.
Tesla has not shed any light on why pothole avoidance has been such an issue for it to solve, but it also has issues identifying large bumps much of the time, so its modeling of sudden changes in road conditions is likely pretty weak at this particular point. I’ve had more issues with large bumps than potholes, personally, but both are issues that need to be resolved.
This is that big bounce that I mentioned in the quoted post.
It’s just a tad too drastic to take at the speed FSD wants to go over it. You can see me quickly swipe down into Sloth, but I intervened. https://t.co/K20PK9ysBg pic.twitter.com/81Oc82ZJcZ

It makes sense that things might be pretty close to being released to the public, as we are going on such an extensive period of time between it being mentioned and it actually being deployed.
Navigation
Navigation is likely the most painful part of using Full Self-Driving, as it routinely takes strange routes, has trouble with local rules (like Except Right Turn Stop Signs in Pennsylvania), and sometimes does not realize that maneuvers it is suggesting are against the law. Turning out of my neighborhood, you cannot turn left, yet my Model Y still suggests it roughly 70 percent of the time when I’m leaving.
However, Tesla might be close to a breakthrough on this. With the Summer Update, Tesla added “Preferred Routes” alongside “Automatic Navigation.”
Preferred Routes prioritized roads that the driver had actually taken before, instead of always defaulting to what the vehicle believes is the most efficient path. This has already solved many of my issues. Formerly, I would turn off the Online Routing setting, and that would eliminate most of my complaints with routing, but then you lose out later on the Live Traffic Visualization.
Tesla’s Navigation has improved tremendously thanks to the Preferred Routes release with the Summer Update, but it still could use some polishing, as it still suggests strange routes from time to time, and it also has a lot of issues getting out of a parking lot. I find that those truly confuse FSD sometimes.
