The correct answer is Google Kubernetes Engine.

Google Kubernetes Engine provides a managed container orchestration platform that lets you control node types, attach GPUs, configure node pools and tune networking for consistent low latency. It supports autoscaling, health checks and rolling updates while keeping cold starts predictable which makes it a good choice for hosting low latency online model endpoints for real time inference.

Cloud Run is a serverless container platform that is great for stateless HTTP workloads but it can introduce cold starts and it gives less control over node level resources which can make strict low latency requirements harder to meet.

Google Compute Engine offers raw virtual machines that can be tuned for latency but it lacks built in container orchestration and automatic rolling updates which increases operational overhead when you need scalable, container based model serving.

On premise servers can be optimized for latency but they add management burden and reduce the benefits of cloud managed services for scaling, availability and integration with cloud AI and monitoring tools.
