Our review
Pros
  • Horizontal and traffic-based autoscaling with configurable replicas
  • GPU, multi-node serving and dynamic request batching
  • OpenAI-compatible APIs plus Kubernetes deployment through KubeRay
  • Serves models from multiple machine learning and deep learning frameworks
  • Supports dynamic batching, ensembles, streaming, and concurrent execution
  • Provides HTTP/gRPC APIs, model management, and Prometheus metrics
Cons
  • Requires teams to operate their own Ray-based serving environment
  • Not a vendor-hosted inference service with managed operations
  • Composable deployment graphs may add architecture and maintenance work
  • Dedicated self-hosted deployment leaves operations with the platform team
  • Not positioned as a managed autoscaling service
  • Its breadth is geared toward engineering and platform teams
