Elon Musk said Tesla is close to taping out its next-generation AI5 chip, has begun work on AI6 and aims to move a new AI chip design into volume production every 12 months (current in cars is AI4), signaling an accelerated in‑house hardware roadmap as the company leans into AI and robotics. Musk noted Tesla’s in‑house team has designed and deployed several million AI chips across vehicles and data centers, touted plans to ultimately produce chips at volumes “higher than all other AI chips combined,” and highlighted a $16.5 billion Samsung agreement that includes a Texas facility for AI6. Citing likely supplier shortfalls, he is exploring a dedicated Tesla semiconductor fab (“terra fab”) targeting 100,000 wafer starts/month scaling to 1 million, versus TSMC’s ~17 million wafers/year (~1.42 million/month), underscoring the company’s push to vertically integrate and the potential to strain global chip supply chains while accelerating Tesla’s autonomy and robotics ambitions.
Elon Musk said Tesla is close to taping out its next-generation AI5 chip, has begun development of AI6, and that the current production version in cars is AI4; he reiterated a target of moving a new AI chip design into volume production every 12 months and claimed Tesla’s internal team has designed and deployed several million AI chips across vehicles and data centers. Musk highlighted a $16.5 billion Samsung agreement to produce AI semiconductors for Tesla, including work at a new Texas facility tied to AI6, while noting continued reliance on TSMC and Samsung and consideration of an Intel partnership. Tesla describes AI5 as more cost-effective and power-efficient and signals an ambition to ultimately manufacture chips at volumes “higher than all other AI chips combined,” which would require substantial scale-up and could further strain global chip supply chains. To address supplier shortfalls Musk proposed a potential in-house “terra fab” beginning at 100,000 wafer starts/month scaling toward 1 million, contrasted with TSMC’s ~17 million wafers/year (~1.42 million/month) capacity in 2024, underscoring large capex and execution risk. Key near-term catalysts and risks are clear: confirmation of AI5 tape-out and volume ramp, Samsung’s production execution under the $16.5 billion agreement, any formal fab commitment or partnership with Intel, and Tesla’s ability to staff advanced chip and board engineering at scale; failure on these fronts would delay autonomous/robotics roadmap benefits and increase capital intensity and supply-chain exposure.
