# Tesla FSD-Bot, brain

Tesla's neural-net brain derived from the FSD vehicle stack plus Dojo training infrastructure. V3 runs on the Tesla AI5 chip with roughly 5x the memory bandwidth of the predecessor. On-device, vision-based, sharing architecture with Tesla vehicles. The Tesla AI-silicon advantage (FSD plus Dojo) is a real engineering edge. Less specified than Figure 03's stack was at the equivalent stage; full V3 specs are unknown as of mid-2026, with a summer 2026 unveil expected. Verified-vs-claimed: FSD-as-precedent is mixed; 'almost done' for nearly a decade.

## Architecture

Neural-net brain derived from the Tesla FSD stack plus Dojo training. V3 runs on the Tesla AI5 chip (roughly 5x memory bandwidth of predecessor). On-device, vision-based, shares architecture with Tesla vehicles.


## Key facts

- **DEPLOY maturity rationale:** Optimus runs internally at Tesla factories for learning, not productive work (per Musk Q4 2025). Pilot, not commercial or production, despite mass-production ambitions
- **AI-silicon advantage:** Tesla FSD plus Dojo training infrastructure
- **V3 chip:** Tesla AI5 (roughly 5x memory bandwidth of predecessor)
- **Specs disclosure:** Full V3 specs unknown mid-2026; summer 2026 unveil expected; less specified than Figure 03 was at the equivalent stage
- **Verified-vs-claimed framing:** FSD-as-precedent is mixed; the 'almost done' framing has held for nearly a decade
- **Dual-stack architecture:** Serves as the System 1 visuomotor layer of Tesla Optimus's dual-brain architecture, paired with xAI's Grok as the System 2 conversational and reasoning layer. Grok handles natural-language reasoning while these FSD-derived neural networks handle physical perception and movement.
