Infrastructure Trends: On-Device, Edge, and Cloud for AI Builders
By Riley Chen
Where teams are running
- On-device copilots for field teams: sub-120ms responses with no cell service required.
- Edge caches for prompts and retrieval snippets, cutting UI latency by 35%.
- Cloud bursts for heavy training, paired with nightly quantization to keep costs flat.
Decision tree
Use on-device for privacy and low latency, edge for personalization, and cloud for experimentation. Keep observability consistent so you can move workloads without losing trust.
Tooling to try
- Lightweight vector stores at the edge
- Slim orchestration layers with policy-as-code
- Traffic replay harnesses to benchmark every deployment
