Report: Tesla Cybercab Packs More Powerful FSD Computer

AUSTIN, Texas — Tesla purpose-built robotaxi appears to be getting the best silicon in the lineup. According to a new report, production Cybercab units are running a more powerful version of Tesla Full Self-Driving computer than the one shipping in todays Model 3 and Model Y.

More Memory, Fewer Bottlenecks

The headline change is onboard memory. Sources say the Cybercab computer carries more RAM than the Hardware 4 setup in current consumer vehicles. For context, each AI4 chip pairs with 16GB of RAM, and because one FSD computer houses two chips, the effective total is 32GB. The Cybercab reportedly beats that ceiling, though the exact figure remains under wraps.

That extra headroom matters because Tesla neural networks keep growing. Larger self-driving models demand more memory, and the development team has increasingly bumped against limits on consumer hardware. Giving the Cybercab more RAM ensures Tesla driverless fleet can run bigger, smarter models for years, a fitting foundation for the vehicle now ramping toward mass production at Giga Texas.

AI4+ Today, AI5 on the Horizon

It is not yet clear whether these early Cybercabs run a pre-production version of the AI4+ chip Tesla announced on its first-quarter earnings call, a doubled-up pair of current AI4 boards, or even an early sample of the AI5 processor that is not due for mass production until 2027. Tesla has said AI4+ will roughly double total package memory to 64GB, so equipping the Cybercab with an advance version would hand the robotaxi generous room to grow.

The upgrade lines up with how these cars are meant to operate. Tesla first-responder documentation explicitly describes the Cybercab as running an SAE Level 4 autonomous mode, designed to drive with no human intervention at all. Backing that promise with a more capable computer is exactly the kind of engineering margin a driverless vehicle needs, and it complements the accessibility-first design Tesla showcased for blind riders.

Built to Lead the Fleet

Tesla recently began testing Cybercabs without steering wheels or pedals on public roads in Austin, and the company has said the two-seater will serve as the primary vehicle in its Robotaxi network, freeing cabin space while cutting weight and operating costs.

As Not a Tesla App reported, the more powerful computer gives fresh insight into what is actually running beneath the Cybercab sleek shell as production scales.

If the details hold, the Cybercab will roll off the line not just as Tesla cheapest path to autonomy, but as its most capable one, a robotaxi engineered with enough compute to keep learning long after it hits the road.
