About

vLLM is a fast and easy-to-use library for LLM inference and serving.

Originally developed in the Sky Computing Lab at UC Berkeley, vLLM has grown into one of the most active open-source AI projects built and maintained by a diverse community of many dozens of academic institutions and companies from over 2000 contributors.

vLLM is fast with:

  • State-of-the-art serving throughput
  • Efficient management of attention key and value memory with PagedAttention
  • Continuous batching of incoming requests, chunked prefill, prefix caching
  • Fast and flexible model execution with piecewise and full CUDA/HIP graphs
  • Quantization: FP8, MXFP8/MXFP4, NVFP4, INT8, INT4, GPTQ/AWQ, GGUF, compressed-tensors, ModelOpt, TorchAO, and more
  • Optimized attention kernels including FlashAttention, FlashInfer, TRTLLM-GEN, FlashMLA, and Triton
  • Optimized GEMM/MoE kernels for various precisions using CUTLASS, TRTLLM-GEN, CuTeDSL
  • Speculative decoding including n-gram, suffix, EAGLE, DFlash
  • Automatic kernel generation and graph-level transformations using torch.compile
  • Disaggregated prefill, decode, and encode

vLLM is flexible and easy to use with:

  • Seamless integration with popular Hugging Face models
  • High-throughput serving with various decoding algorithms, including parallel sampling, beam search, and more
  • Tensor, pipeline, data, expert, and context parallelism for distributed inference
  • Streaming outputs
  • Generation of structured outputs using xgrammar or guidance
  • Tool calling and reasoning parsers
  • OpenAI-compatible API server, plus Anthropic Messages API and gRPC support
  • Efficient multi-LoRA support for dense and MoE layers
  • Support for NVIDIA GPUs, AMD GPUs, Intel GPUs, and x86/ARM/PowerPC CPUs. Additionally, diverse hardware plugins such as Google TPUs, Intel Gaudi, IBM Spyre, Huawei Ascend, Rebellions NPU, Apple Silicon, MetaX GPU, and more.

vLLM seamlessly supports 200+ model architectures on Hugging Face, including:

  • Decoder-only LLMs (e.g., Llama, Qwen, Gemma)
  • Mixture-of-Expert LLMs (e.g., Mixtral, DeepSeek-V3, Qwen-MoE, GPT-OSS)
  • Hybrid attention and state-space models (e.g., Mamba, Qwen3.5)
  • Multi-modal models (e.g., LLaVA, Qwen-VL, Pixtral)
  • Embedding and retrieval models (e.g., E5-Mistral, GTE, ColBERT)
  • Reward and classification models (e.g., Qwen-Math)
