A Samsung Foundry engineer has publicly corroborated that the Tesla-Samsung AI5 chip has reached tape-out, marking the completion of its design phase and clearing the runway for manufacturing at Samsung's Taylor, Texas plant on a 2nm process. The comment came from an individual Samsung Foundry Principal Engineer's post, surfaced by Sawyer Merritt on X — the first public remark from the Samsung side since Elon Musk publicly confirmed the tape-out in April. It is not a formal company announcement.
The disclosure sharpens the picture around what Tesla has been calling AI5, also referred to as Hardware 5 (HW5) — the successor to the HW4 compute platform currently shipping in Model 3, Model Y, Model S, Model X and Cybertruck. It also fuels fresh speculation, echoed by content creator Dirty Tesla, about whether a refreshed Model Y ("Model YL") could be the first vehicle to carry HW5 as early as next year.
Tape-out is the point at which a chip's design is finalized and handed off to the fab for physical manufacturing. It doesn't mean chips are rolling off the line — engineering samples typically follow months later, with volume production behind that. According to previous reporting on the AI5 program, engineering samples are expected in late 2026, with high-volume production following in 2027 — TrendForce puts vehicle-bound volume production at mid-to-late 2027.
The Samsung engineer's phrasing — that AI5 "will soon be integrated into Tesla's newest products" — is notable but should be read carefully. "Soon" in semiconductor terms is measured in quarters, not weeks. Merritt also noted in his post that volume production won't start immediately...
