What each one is

vLLM

Inference server · Apache-2.0

vLLM is a high-throughput inference and serving engine using PagedAttention to maximize GPU utilization, the default choice for serving open models at scale.

  • Best-in-class throughput via PagedAttention
  • OpenAI-compatible server, broad model support
  • The de-facto standard for production serving

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
