IT Home On October 28, Tesla’s FSD computer will adopt a new name. Tesla’s official owner’s manual has replaced “FSD Computer” with “SI Computer” in multiple locations, including those for the Model 3, Model Y, and Cybertruck.
This seems to be a precursor to Tesla’s official adjustment of the naming scheme for in-car computers. According to the new naming rules, HW2.0, HW2.5, HW3, and AI4 may be renamed as SI2.0, SI2.5, SI3, and SI4 respectively.
The car owner manual has changed
Currently, the section related to FSD in the Model Y owner’s manual has been changed to: “The SI Computer equipped with the Model Y is designed to use these input information to quickly process neural network data and make decisions, guiding you to your destination.”
The air conditioning control section has also adopted a new name. The manual indicates that the related functions “do not support vehicles equipped with SI Computer 2.0 or 2.5”.
The manual also instructs car owners: “Click ‘Controls’ > ‘Software’, and check ‘SI Computer’ to confirm the computer model equipped in the vehicle.” Previously, this option was called “AI Computer”.
Although this name may not have appeared in the vehicle yet, the update to the manual suggests that Tesla might soon enable a new name on the vehicle’s dashboard via a software update.
Why did Tesla abandon “AI”?
IT Home noticed that this adjustment is consistent with Elon Musk’s change of name from SpaceXAI to SpaceXSI earlier this month. SpaceXSI is the abbreviation for SpaceX Super Intelligence. Since then, Tesla AI has also been adjusted to Tesla Super Intelligence, which is Tesla SI.
This change occurred after U.S. President Donald Trump signed an executive order. The order required administrative agencies to use “Super Intelligence” and “SI” in official materials, replacing “Artificial Intelligence” and “AI”.
Although Musk’s relationship with Trump was once quite tense, from this series of naming changes, it seems that Musk is following the approach of the U.S. government.
This is not the first time Tesla has changed the hardware name. Previously, Tesla renamed HW4 to AI4 to better reflect its optimized design for artificial intelligence tasks. HW3 retained its original name, as it was not originally designed for AI tasks.
Tesla has confirmed that HW3 cannot support unsupervised autonomous driving, and plans to offer a hardware upgrade for vehicles equipped with HW3, so that they can be compatible with unsupervised FSD.
Ashok Elluswamy, Vice President of Tesla, recently said that Tesla may start releasing unsupervised FSD in the second quarter of 2027, and allow car owners to join the Robotaxi driverless taxi network.
The next-generation AI5 chip may also be renamed as SI5
The new naming method may also be applied to future hardware products.
Tesla’s next-generation AI5 chip has currently entered trial production at Samsung’s factory in Texas, USA. According to the new naming convention, the chip may be renamed as SI5 when it is launched in the future, and subsequent chips might be named as SI6, and so on.
As of now, Tesla has not officially announced this rebranding plan. However, if the changes in the owner’s manual are indicative, the new name “SI Computer” may begin to appear on the vehicle’s central display in the upcoming software update.
