Tesla Manuals Switch From AI to SI for FSD Computer Names
Owner's manuals for Model 3, Y, and Cybertruck now reference SI Computer instead of FSD Computer.
Tesla’s official Owner’s Manuals have begun replacing references to the "FSD Computer" with "SI Computer," signaling a potential rebranding of the hardware powering its Full Self-Driving capabilities.
What Happened
The updated documentation, appearing across manuals for the Model 3, Model Y, and Cybertruck, now describes the vehicle's autonomy hardware as the "SI Computer." For instance, the Model Y manual states that the "SI Computer... is designed to use this input, rapidly process neural networks, and make decisions to guide you to your destination." The Climate Controls section also directs users to check the "SI Computer" version under Software settings, replacing the previous "AI Computer" label. Under this new naming convention, existing hardware generations such as HW2.0, HW2.5, HW3, and AI4 would be rebranded as SI2.0, SI2.5, SI3, and SI4.
Why It Matters
This terminology shift aligns with broader corporate and political trends. Earlier this month, Elon Musk renamed SpaceXAI to SpaceXSI (SpaceX Super Intelligence), and Tesla AI has similarly been referred to as Tesla Super Intelligence. The change follows an executive order signed by President Trump directing federal agencies to use "Super Intelligence" and "SI" instead of "Artificial Intelligence" and "AI" in official materials. While Tesla has not officially announced the rename, the manual updates suggest the new labels could appear on vehicle touchscreens in upcoming software updates. This follows a previous rebranding where Tesla changed HW4 to AI4 to reflect its optimization for AI tasks, while retaining the HW3 name for older hardware that did not support unsupervised autonomy.
The Bottom Line
Tesla has updated its owner's manuals to use "SI Computer" instead of "FSD Computer" or "AI Computer," reflecting a shift toward the "Super Intelligence" branding. The change applies to current and future hardware, with the upcoming AI5 chip potentially launching as SI5. An official company announcement regarding the rename has not yet been made.
