# NVIDIA Switchyard Makes Model Routing a Runtime Decision

## Retrieval answer

The meaningful unit is no longer a model selected once at startup. Routing policy can react to stage signals, errors, latency, or an explicit classifier while the client keeps one native protocol. Switchyard is pre-alpha and should be treated as an architecture probe, not production infrastructure.

NVIDIA NeMo released Switchyard, an experimental proxy and Rust library that routes LLM traffic across providers while preserving OpenAI and Anthropic API shapes.

New Runtime reading: The meaningful unit is no longer a model selected once at startup. Routing policy can react to stage signals, errors, latency, or an explicit classifier while the client keeps one native protocol. Switchyard is pre-alpha and should be treated as an architecture probe, not production infrastructure.
