Tesla quietly starts shipping Model Y with new AI4.5 computer
Tesla appears to be quietly rolling out a new version of its Full Self-Driving computer, with new Model Y owners discovering their vehicles are equipped with “Hardware 4.5”, or AI4.5 as it’s being labeled internally.
The discovery comes from owners taking delivery of Fremont-built Model Y vehicles in late December and January, who found a computer labeled “AP4.5” or “AP45” in their cars. The sightings match a part number (2261336-02-A) that was previously spotted in Tesla’s Electronic Parts Catalog for a new FSD computer.
As usual, Tesla made no announcement about the change.
