Episode notes
Vertical Integration Drives Efficiency
- OpenAI and Broadcom built a custom chip and full system together to optimize AI workloads end-to-end.
- Vertical integration across transistor to token delivers large efficiency and performance gains.
Optimize The Whole Stack
- Optimize across the full stack from chips to racks to software to cut cost per token and increase throughput.
- Expect demand to grow faster than efficiency gains, so build significant incremental capacity.
AI Helped Design The Chip
- Greg described using AI to design chip components and finding optimizations that saved months of engineering time.
- He noted many model-suggested optimizations matched expert ideas but were discovered far faster.
