Tesla has posted an update to its Optimus program on X, and it is extremely impressive. Over the course of a short video, Tesla showcased the Gen 2 Optimus prototype, which features an updated design, almost humanlike hand movements, and a lighter weight compared to its previous iterations.
In its short demonstration, the Gen 2 Optimus robot could be seen moving its neck and arms like a human being. Tesla noted that the robot features custom-designed actuators and sensors, as well as a 2-DoF actuated neck. The robot features a 30% walking speed boost from its previous iteration, and it is also 10 kg lighter.
There’s a new bot in town ?
Check this out (until the very end)!https://t.co/duFdhwNe3K pic.twitter.com/8pbhwW0WNc— Tesla Optimus (@Tesla_Optimus) December 13, 2023
It also boasts better balance and control, and it is equipped with faster, 11-DoF hands with tactile sensing on all fingers. Tesla demonstrated the Gen 2 Optimus robot’s hand control by having the robot handle an egg in the video. Tesla ended its video with a couple of Gen 2 Optimus robots dancing to some music — quite impressively, all things considered.
Everything in this video is real, no CGI. All real time, nothing sped up. Incredible hardware improvements from the team. https://t.co/y5QNYaZy0M— Julian Ibarz (@julianibarz) December 13, 2023
So smooth were the movements of Gen 2 Optimus in its demonstration that members of the Tesla Bot team have taken to social media to clarify that the footage is real and not CGI. The Tesla Bot team members also highlighted that the robots’ movements in the video were recorded in real-time, not sped up.
Excited to share our latest bot ! Amazing new platform to build the future of humanoid robotics upon. Very proud of the teams who've all been hard at work to get this to happen 🙂
This new generation, which is in effect the 3rd since we started the program less than 2 years ago,… https://t.co/k2kGFsXUuu— Milan Kovac (@_milankovac_) December 13, 2023
The capabilities of the Gen 2 Optimus robot are very impressive, especially considering the fact that Tesla’s humanoid robot program is just over two years old now. Tesla announced its intentions to build a humanoid robot at its first AI Day event in August 2021, and at the time, all the company had was a static model and a man in a robot suit dancing onstage.

To be fair, the rapid progress of Tesla’s Optimus program was already evident since AI Day 2.0., which was held in September 2022. At the time, Tesla was able to show a development prototype called “Bumblebee,” which was built with off-the-shelf parts, walking on its own without human assistance. The company also revealed a more advanced Optimus robot that’s equipped with Tesla-designed actuators and sensors.
Optimus can now sort objects autonomously ?
Its neural network is trained fully end-to-end: video in, controls out.

The more advanced Optimus prototype, named “Gen 1 Optimus” in Tesla’s recent video announcement, featured smoother movements than “Bumblebee,” but it could not stand on its own feet yet. By May 2023, however, Tesla posted a video on X showing the Gen 1 Optimus walking on its own, and on September 2023, the robot was sorting objects by color. It could even do some yoga moves that required quite a bit of balance.

Elon Musk teases TSMC as potential Terafab partner
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.

Tesla reveals early Robotaxi charging strategy, showing scrappy DNA
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.
Tesla wins FCC approval for wireless Cybercab charging system
The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once
— Abhimanyu Yadav (@WorldlyReviewer) October 3, 2026
It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.
— Elon Musk (@elonmusk) October 12, 2020
For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.

Tesla Robotaxi expands hours, Musk explains why it’s been a challenge
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
