Samsung currently makes AI4.
TSMC will make AI5, which just finished design, initially in Taiwan and then Arizona.
1. Solving the "Two-Language" Development Dilemma
| Chip Generation | Manufacturer | Key Advancement |
|---|---|---|
| AI4 (Current) | Samsung | First-gen Tesla architecture |
| AI5 (2026) | TSMC | Performance boost |
| AI6 (Future) | Samsung Texas | Architecture unification |
2. Manufacturing Revolution: Tesla's Direct Involvement
Samsung agreed to allow Tesla to assist in maximizing manufacturing efficiency.
