Our review
Pros
  • CPU and CUDA GPU acceleration through ND4J
  • Distributed training, evaluation, and inference with Apache Spark
  • Keras and TensorFlow frozen-model import for JVM projects
  • Serves models from multiple frameworks through HTTP/REST and gRPC APIs
  • Supports dynamic batching, concurrent execution, and sequence state management
  • Exposes Prometheus metrics for GPU and request statistics
Cons
  • Self-hosted deployment requires teams to manage their own infrastructure
  • Support is provided through the community channel
  • Workflow breadth is narrower than broader deep-learning suites
  • Focused on inference serving rather than model development or training
  • Production deployment requires engineering or platform-team ownership
  • Accelerator support varies beyond NVIDIA GPUs and CPUs
