Elon Musk says Tesla’s Summon is ‘a fun trick’ that will only get better
Tesla’s Smart Summon feature is one of the most notable Full Self-Driving (FSD) suite characteristics. While driving on public roads and highways with minimal interventions thanks to the newly released FSD Beta V9 is already wildly impressive due to the accuracy and incredibly confident nature it operates in, Summon is one feature that seems to capture the attention of most non-Tesla informed people more often than not. Although CEO Elon Musk said that Summon is “mostly just a fun trick” for now, improvements are coming that will make its nature more useful than a surefire way to impress people nearby.
“Current Summon is sometimes useful,” Musk said on Twitter this weekend, “but mostly just a fun trick.” Indeed, many Tesla owners have utilized Summon to bring their cars to them during torrential downpours or through tricky parking lots, and it’s quite impressive with its accuracy. However, the feature isn’t perfect. Some owners have indicated that there are definitely improvements that need to be unloaded into Summon before it becomes a mainstream and more frequently utilized way to get into a car without having to walk to it.
Current Summon is sometimes useful, but mostly just a fun trick. Once we move summon (plus highway driving) to a single FSD stack, it will be sublime.

In mid-July 2020, one owner said that Summon wasn’t effective on his driveway due to the excessive grade. The steep nature of the owner’s driveway wouldn’t allow Summon to operate properly, and Elon Musk said that the improvements would ultimately come from “upgrading Autopilot to 4D vs. ~2.5D, then it will go up very steep slopes.”
Musk maintains that the improvements to Summon will occur when the feature, along with highway driving functionalities, is switched to a single software stack. Currently, the two features operate on different stacks, likely because they are of a completely unrelated nature. Instead, it seems Tesla will merge multiple FSD functionalities into one stack, and Summon will depend on the Neural Network for improvements.

The switch from what Musk calls ~2.5D to 4D is the main focus of the new Dojo Supercomputer. Recently, Tesla’s Senior Director of Artificial Intelligence, Andrej Karpathy, detailed the Supercomputer that Tesla is utilizing to bring in the Dojo era. What is likely the most powerful computer globally, the massive system is utilized to handle large amounts of video, clean data, and diverse scenarios that make the suite well-rounded and more complex with every mile driven. Dojo is set to be released later this year, according to Tesla.
Summon, while definitely a fun feature, would be widely beneficial if it was more accurate and could operate in various scenarios, like on steeper grades. For example, Summon has been utilized by those in a wheelchair to back out their vehicle when parked in tight quarters. Additionally, Summon has been used to bring vehicles to the entrance of a grocery store to pick up a family. The feature has some serious potential moving forward. Still, Tesla realizes the improvements it has talked about are likely the bridge that will connect Summon from a ‘fun trick’ to a beneficial characteristic.

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.
