Episode notes
AI Shaping Infrastructure Layers
- AI infrastructure is fundamentally shifting to support new workloads like low-latency image and video generation.
- Different AI modalities like language models and diffusion models require distinct infrastructure optimizations.
Layered Model Usage in Production
- Production AI stacks increasingly layer small deterministic models before invoking large language models.
- This layered approach optimizes costs and leverages each model's strengths effectively.
Automate Mundane Document Tasks
- Automate soul-crushing tasks like document transcription with AI to free humans for higher-level work.
- Use specialized smaller models to handle complex, domain-specific document parsing before passing data to larger models.
