Tesla\u2019s FSD computers are getting a new name. Tesla\u2019s official Owner\u2019s Manual has replaced \u201cFSD Computer\u201d with \u201cSI Computer\u201d in several places, and the change shows up across the manuals for the Model 3, Model Y, and Cybertruck (H\/T to @Tesla_App_iOS<\/a>).<\/p>\n

It looks like a precursor to Tesla officially renaming the computers in its vehicles. Under the new naming scheme, HW2.0, HW2.5, HW3, and AI4 would become SI2.0, SI2.5, SI3, and SI4.<\/p>\n

What the Manual Says Now<\/p>\n

The FSD section of the Model Y manual now reads, \u201cThe SI Computer installed in Model Y is designed to use this input, rapidly process neural networks, and make decisions to guide you to your destination.\u201d<\/p>\n

The Climate Controls section uses the new name too, noting that the feature \u201cis not supported in vehicles with SI Computer 2.0 or 2.5.\u201d It then tells owners to \u201cTouch Controls > Software and look at SI Computer to find out which computer your vehicle has.\u201d It was previously listed as AI Computer. <\/p>\n

Even if the new label hasn\u2019t reached vehicles yet, the updated manual suggests it could show up on the touchscreen soon.<\/p>\n

Yes, SI4 makes more sense<\/p>\n

Why Tesla Is Dropping \u201cAI\u201d<\/p>\n

The change follows Musk\u2019s move to rename SpaceXAI to SpaceXSI<\/a>, short for SpaceX Super Intelligence, earlier this month. Tesla AI has since also become Tesla Super Intelligence, or Tesla SI. The shift came after President Trump signed an executive order directing executive-branch agencies to use \u201cSuper Intelligence\u201d and \u201cSI\u201d instead of \u201cArtificial Intelligence\u201d and \u201cAI\u201d in official materials. Musk appears to be following the government\u2019s lead, despite his historically rocky relationship with Trump<\/a>.<\/p>\n

It\u2019s not Tesla\u2019s first hardware rename. Tesla previously renamed HW4 to AI4 to better reflect what it was optimized for, while HW3 kept its name since it wasn\u2019t built with AI in mind. Tesla has confirmed HW3 won\u2019t support unsupervised autonomy, and it plans to offer hardware upgrades for HW3 vehicles<\/a> to make them compatible with unsupervised FSD. VP Ashok Elluswamy recently said Tesla could start rolling out unsupervised FSD by Q2 2027<\/a>.<\/p>\n

AI5 Could Become SI5<\/p>\n

The new naming would also apply to future hardware. Tesla\u2019s next-gen AI5 chip, now in trial production at Samsung\u2019s Texas fab<\/a>, could launch as SI5 instead, with later chips following as SI6 and beyond.<\/p>\n

Tesla hasn\u2019t officially announced the rename yet. If the manual is any sign, though, SI Computer labels could start appearing on vehicle screens in an upcoming software update.<\/p>\n
