A single reveal can reshape an industry, and a recent announcement did exactly that, pulling engineers, investors, and competitors in all at once. Elon Musk pulled back the curtain on Tesla’s AI5 chip design, an intersection of ambition and silicon. However, the announcement came paired with a public nod to Samsung’s collaboration on the project.
Elon Musk debuts the design for AI5 chip
And thank you to @TaiwanSemi_TSC and @Samsung for your support in bringing this chip to production! It will be one of most produced AI chips ever.
— Elon Musk (@elonmusk) April 15, 2026
With a post that rippled through tech circles, Elon Musk unveiled the design language of Tesla’s AI5 chip, precision, power, and intent etched in silicon.
The tech mogul revealed a first sample of Tesla’s AI5 hardware on Wednesday, April 15. The chip targets AI applications across Tesla vehicles, Optimus robots, and potentially xAI data centers.
Musk turned to X (formerly Twitter) to announce, sharing a glimpse of the new AI5 hardware. “Congrats to the Tesla_AI chip design team on taping out AI5,” the post read. “AI6, Dojo 3 and other exciting chips in work.”
In a reply to the post, the SpaceX CEO wrote, “And thank you to @TaiwanSemi_TSC and Samsung for your support in bringing this chip to production! It will be one of the most produced AI chips ever.”
Tesla’s AI5 processor module pairs a relatively small ASIC die with 12 SK Hynix memory packages, likely GDDR6 or GDDR7. The die is about half a reticle, based on Musk’s earlier remarks. The memory uses an organic substrate and carries standard DRAM product markings. Tesla has not confirmed the exact width of AI5’s memory interface.
However, 12 memory packages indicate wide memory I/O. With 12 GDDR6/7 ICs, the AI5 ASIC would have a 384-bit memory interface. Depending on the memory type, bandwidth could range from 768 GB/s to 1.536 TB/s. Tesla has not released full performance specifications for AI5. But Musk claims it brings major gains, with up to a 40X uplift over AI4 in specific workloads.
Although Elon Musk said that AI5 was just “taped out,” he shared an image of a fabricated processor already marked “KR 2613.” That suggests the ASIC was packaged in week 13 of 2026.
