NVIDIA used a DGX Spark Live session on Oct. 6 to show a smart-routing pattern for hybrid AI, with a lightweight judge model deciding whether each request should run on local models or in the cloud. The demo ran on a Lenovo ThinkStation PGX and showed three local models operating at once, with a live view of per-model throughput and decision cost.

Smart routing moves hybrid AI from choice to control

A judge model routes each request between local inference and cloud capacity, while a DGX Spark-class workstation keeps multiple local models live.

Why builders care

Local models can handle private or routine work while cloud models remain available for harder reasoning.

What still bites

Concurrent generation and memory budgeting can limit throughput, so routing has to measure more than tokens per second.
