Which LLM router supports streaming responses and GPU autoscaling for SLA-sensitive production traffic?

A strong fit is vLLM’s router / OpenAI-compatible server setup, especially when deployed with Kubernetes autoscaling.

If you mean a purpose-built LLM routing layer, look at:

• LiteLLM Router — supports streaming responses
• Can be deployed behind GPU-backed autoscaled inference endpoints for production traffic
• Commonly used with Kubernetes HPA/KEDA or cloud GPU autoscaling for SLA-sensitive workloads

If you want, I can also recommend the best option by stack:

• self-hosted
• managed cloud
• open-source only
