Multi-Embodiment Physical AI Platform Readiness

The Tesla FSD–Optimus Unified Stack


Abstract

The concluding paper of the series takes the Tesla FSD–Optimus unified stack as the empirical anchor closing the loop between D1’s AR0–AR5 framework and D2’s 22-OEM assessment. Through a clinical dissection from silicon to behavior, it distils Tesla’s eleven officially disclosed shared layers into three reuse mechanisms — physical, intelligence, and an implicit organizational twelfth layer — and characterizes the precise boundary of cross-morphology reuse: accumulated capability is reusable, morphology-dependent high-frequency motion control is not. The central thesis: Tesla functions as an AR4 reference frame, not a template for replication.
