About vLLM

vLLM is an open-source, high-throughput and memory-efficient inference engine for large language models, built by UC Berkeley. Its PagedAttention algorithm manages GPU memory like an OS manages RAM, enabling 2-4× more throughput than standard HuggingFace inference. Provides an OpenAI-compatible server for drop-in deployment.

Designed For

  • Self-hosted LLM serving
  • High-throughput inference
  • Production LLM deployment
  • Multi-GPU serving
