Elon Musk’s Neuralink unveils sleek V0.9 device, uses sassy pigs for live brain machine demo
After another year of successfully staying in the shadows, Elon Musk’s Neuralink has revealed what’s been going on behind the scenes in terms of technological progress. In a live streamed event on Friday afternoon, the brain-machine interface company gave a demonstration, took questions, and left audiences with even more to mull over than ever.
“The primary purpose of this demo is recruiting,” Musk stated at the very beginning of the presentation. He emphasized that everyone at some point in their life will face a brain or spine problem – all inherently electrical – meaning it takes electrical solutions to solve electrical problems. Neuralink’s goals are to solve these problems for anyone who wants them solved, and that application will be simple and reversible with no negative effects.
Two pigs were used for the ‘real-time’ demonstration promised in the days leading up to the event. The first, named Gertrude, had a Neuralink implant installed for two months and was shown to be healthy and happy. A second pig, named Dorothy, had the implant previously installed and removed with no side effects afterward.

After a bit of a delay from the amusingly sassy Neuralink-implanted pigs, the live stream and in-house audience witnessed Gertrude’s device in action. Notably, the neural implants could predict all the limb movements of the pigs based on the neural activity being read. Each reading was shown on a screen and musical notes attached as the data was processed.
Overall, here are some of the main takeaways from the presentation.
- The Neuralink implant device has been dramatically simplified since Summer 2019. Its design will be very low profile and nearly invisible on the outside, leaving only a small scar that could be covered by hair. “It’s like a FitBit in your skull with tiny wires,” Musk half-joked. “I could have it right now and you wouldn’t even know. Maybe I do!”
- The implant device is inductively charged, much like wireless smartphones are charged. It will also have functions that are akin to those available on smartwatches today.
- A “smart” robot installs the device, which requires engineering talent to accomplish, hence the recruiting focus of the Neuralink event. The “V2” robot featured in this year’s presentation looks like a step up from last year’s machine.
- The electrodes are installed without general anesthesia, no bleeding, and no noticeable damage. The currently developed robot has done all the current implant installations to date.
- The implant can be installed and removed without any side effects.
- You can have multiple Neuralink devices implanted and they will work seamlessly.
- The implant device would have an application linked to your phones.
- Neuralink received a ‘breakthrough device’ designation from the FDA in July, and the company is working with the agency to make the technology as safe as possible.
- The device will eventually be able to be sewn deeper within the brain, thereby having access to a greater range of functions beyond the upper cortex. Examples are motor function, depression, and addiction.
- Getting a Neuralink should take less than an hour, without the need for general anesthesia. Users could have the surgery done in the morning and go home later during the day.

The idea for Musk’s AI-focused brain venture first seemed to really take off after his appearance at Vox Media’s Recode Code Conference in 2016. The CEO had discussed the concept of a neural lace device on several occasions up to that point and suggested at the conference that he might be willing to tackle the challenge himself. A few months later, he revealed that he was in fact working on the idea, which was detailed at great length by Tim Urban on his website Wait But Why.
“He started Neuralink to accelerate our pace into the Wizard Era—into a world where he says that ‘everyone who wants to have this AI extension of themselves could have one, so there would be billions of individual human-AI symbiotes who, collectively, make decisions about the future.’ A world where AI really could be of the people, by the people, for the people,” Urban summarized. Given that bigger picture perspective, the 2020 Neuralink event seems even more impactful.
Neuralink’s official Twitter account opened the virtual floor to questions using the #askneuralink hashtag the night before the event, prompting several questions during the presentation. However, Musk fanned the building curiosity in the hours beforehand. “Giant gap between experimental medical device for use only in patients with extreme medical problems & widespread consumer use. This is way harder than making a small number of prototypes,” Musk responded to one question directed towards the mass market viability of a future Neuralink product line.

Also in the days prior to the Neuralink event, Musk teased a few more bits of information about what to expect. “Live webcast of working @Neuralink device,” he said. Just prior to his confirmation of the device demonstration, he revealed that version two of the robot initially shown in the first progress update in 2019 wasn’t quite up to the level of a LASIK eye surgery machine, though only a few years away.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:Â
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.Â
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.Â
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.Â
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.Â
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
