What each one is

TensorRT-LLM

Inference engine (NVIDIA) · Apache-2.0

TensorRT-LLM compiles models into highly optimized NVIDIA kernels with in-flight batching, quantization and multi-GPU tensor parallelism — the reference for squeezing maximum tokens per second from NVIDIA hardware.

  • Best-in-class throughput on NVIDIA hardware
  • FP8/INT4 quantization with official support
  • Deep integration with Triton and NVIDIA stack

Ray Serve

Serving framework · Apache-2.0

Ray Serve is a scalable model-serving library that composes multiple models and Python business logic into one deployment, scaling across a Ray cluster.

  • Composes several models in one pipeline
  • Autoscaling across a cluster
  • Framework-agnostic
