Musk: Tesla AI5 inference chip ~40x better than AI4 (8x compute, 9x memory, 5x bandwidth); FSD v14 raises parameters 10x over next few months
“We're finalizing the design of AI5, which will be an immense jump from AI4. By some metrics, the improvement in AI5 will be 40 times better than AI4... eight times more compute, about nine times more memory, roughly five times more memory bandwidth... version 14 will be the biggest upgrade in Tesla software since version 12. We are increasing the parameter count by an order of magnitude.”
Why it matters
Concrete specs and timeline for Tesla's next-gen inference silicon and FSD software refresh, reflecting co-design of chip and software — key to the robotaxi and Optimus economics.
Investment implication
Supports Tesla's autonomy/robotaxi thesis and reduces dependence on external AI chip vendors; relevant for positioning versus NVDA-centric autonomy stacks (e.g., Waymo) and for Tesla's in-house silicon narrative.
