Work with the Google Kubernetes Engine team. Three changes: direct streaming with a control-plane-only endpoint picker, a new vLLM Ray executor backend, and HAProxy ingress. Together they give up to 4.4x more throughput on prefill-heavy workloads and 24x on decode-heavy ones.
Serving Qwen on GKE with Ray Serve and vLLM, with an ADK agent in front of it for chat and tool use. Runs on TPU nodes, with Ray handling autoscaling and fault tolerance.
Ray 2.55 adds fault tolerance for data-parallel groups in large MoE deployments. When one rank fails, the whole group is marked unhealthy and recovers together, instead of the failure cascading across every GPU in it.
