Episode notes
Tesla's Ambitious TerraFab Production Goal
- Tesla plans a $20 billion TerraFab to produce up to 200 billion AI and memory chips annually at a 2 nm node.
- The target of 100,000 wafer starts per month aims to push manufacturing to the absolute global volume limits.
AI-5 Design Targets Massive Inference Gains
- The planned AI-5 chip claims 40–50× compute over AI-4 and nine times more memory, optimized for inference.
- It's intended to run full self-driving, Robotaxi, and humanoid robot workloads without constant cloud reliance.
Owning The Stack Eliminates Supply Vulnerabilities
- Vertical integration would let Tesla control silicon, data pipelines, and high-level software to eliminate third-party shortages.
- Owning the factory removes supply-chain bottlenecks that force rivals to "wait in line" for silicon.
