ModelRefs / Edge Runtime Stack — Architecture Pattern
Edge Runtime Stack — Architecture Pattern
LLM inference at the network edge with regional model replicas and consistent token streaming.
Overview
Run small/mid models in edge PoPs to minimize round-trip latency for global users; route to regional replicas with traffic-aware load balancing.
When to use it: You need globally low latency without on-device constraints.

Known failure modes
- Replica drift — PoPs serve different model versions. Mitigation: Atomic global rollouts; pinned versions.
When not to use it
- Running huge dense models at edge.
