Tesla AI5 tapes out at Samsung Foundry on 2nm; production starts at Taylor fab in 2026
Tesla's AI5 chip has reached tape-out at Samsung Foundry and is scheduled for production at Samsung's Taylor, Texas facility using the company's 2-nanometer process, according to a LinkedIn post by Samsung Foundry principal engineer James Kim on July 13. This marks the completion of the design phase and handover to manufacturing. Tesla had previously announced in April that it would tap out AI5 designs to both TSMC and Samsung, with slightly different versions adapted to each foundry's process, but the Samsung version arrived several months after TSMC's tape-out.
The development is significant because Samsung is building AI5 on its advanced 2nm node—a process initially expected to debut with Tesla's next-generation AI6 chip. The move indicates Samsung's 2nm yields have improved enough to win a high-profile customer for a production volume chip. Engineering samples are expected in late 2026, with volume production targeted for mid-to-late 2027 to support Tesla's vehicles, humanoid robots, and data centers. The dual-foundry strategy provides Tesla supply-chain flexibility and validates Samsung's push to compete with TSMC at the leading edge.
For infrastructure architects, this is a capacity and supply-chain milestone: Samsung's success at 2nm opens a second source for leading-edge AI silicon at volume, reducing dependency on TSMC. It also signals that improving yields on advanced nodes are enabling new customers like Anthropic to explore Samsung partnerships. Tesla's bet that two foundries can share an identical design also models a pragmatic hedge against fab disruption—relevant as competition for wafer capacity at 2nm and below intensifies.
