First look at Tesla’s new UI and driving visualizations for FSD beta in action
Tesla has started rolling out software version 2020.40.8.12 to users of the company’s limited Full Self-Driving beta, and based on observations from the EV community, it appears that the update includes a new UI that is optimized for the operation of the FSD suite. This is evident in the UI’s larger space for FSD’s driving visualizations, as well as its smoother, vector renders for driving paths, objects, and streets.
Images of Tesla’s new UI were shared by limited FSD beta user Tesla Raj, who seemed to be among the first Model 3 owners who received the update. As noted by the Tesla enthusiast, immediately noticeable was the larger space allotted for visualizations. This is especially striking when the vehicle is in Park, as the Tesla avatar on the display has now gotten considerably larger and more detailed. The animation when opening the trunk, frunk, and doors is now smoother as well.
The changes in Tesla’s UI does affect the layout of the center display. With a larger space allotted for driving visualizations, the area for the map has been reduced. The Tesla “T” logo at the top of the display has also been removed. Whether this would be popular among Tesla owners is up for question, though it is evident that the change was made with regards to the growing functionalities of the Full Self-Driving suite. Tesla explained this in its Release Notes for 2020.40.8.12.
Driving Visualization Improvements
The driving visualization has been improved to better support Full Self-Driving capabilities by increasing the display size to show additional surrounding information. The next turn will now appear above the visualization if the navigation turn list is covered by another app.
With the larger visualization, select items have slightly moved but will continue to look and behave the same. Some notable differences include the following:
- Quick access to the backup camera and wipers has moved to the bottom bar.
- Autopilot set speed is now displayed directly below the speedometer and can continue to be adjusted using the right steering wheel scroll wheel. The speed will turn blue when Autopilot is engaged.
What is rather interesting is the fact that the improvements being introduced to the Full Self-Driving beta have been coming at an incredibly rapid pace. Since rolling out to members of the limited FSD beta just over a week ago, the system’s capabilities have already started exhibiting more refinements. This was observed by the Tesla Owners Silicon Valley group, who asked how the new update and UI could enhance FSD’s actual performance on the road. In a response, Musk stated that the update may result in fewer interventions.
“We measure this primarily in intervention probability. This update addressed several issues, resulting in perhaps ~1/3 fewer interventions. Many of the improvements consist of fixing silly bugs vs grand eureka moments. True for most beta releases in my experience,” Musk wrote.
Elaborating further, Musk explained that as Full Self-Driving improves, the faults that will be experienced by the system will likely decrease significantly. The CEO explained that while FSD’s faults would never be zero, there will eventually be a point when its probability of faults will be notably lower than that of an average human driver. Musk added that the updates to the limited FSD beta would be quite rapid as well, with new improvements being rolled out every 5 to 10 days.

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:
“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.
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.
“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.
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.
“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.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
