## Key Design Decisions

| Decision | Choice | Rationale |
|----------|--------|-----------|
| Serving framework | vLLM | Continuous batching, PagedAttention |
| GPU type (production) | A100 80GB | Best price/performance for inference |
| Storage | Shared PVC (SSD) | Fast model loading across replicas |
| Autoscaling | KServe + Knative | Native scale-to-zero support |
| Container registry | GHCR | GitHub integration, free for public |
