Ray Summit CPF is Open (June 4th to June 20th)!
There will be a track for vLLM at the Ray Summit (09/30-10/02, SF) this year! If you have cool projects related to vLLM or LLM inference, we would love to see your proposals. This will be a great chance for everyone in the community to get together and learn. Please submit your proposal here

vLLM is a fast and easy-to-use library for LLM inference and serving.
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
- Fast model execution with CUDA/HIP graph
- Quantization: GPTQ, AWQ, SqueezeLLM, FP8 KV Cache
- Optimized CUDA kernels
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 parallelism support for distributed inference
- Streaming outputs
- OpenAI-compatible API server
- Support NVIDIA GPUs, AMD GPUs, and Intel CPUs
- (Experimental) Prefix caching support
- (Experimental) Multi-lora support
vLLM seamlessly supports most popular open-source models on HuggingFace, including:
- Transformer-like LLMs (e.g., Llama)
- Mixture-of-Expert LLMs (e.g., Mixtral)
- Multi-modal LLMs (e.g., LLaVA)
Find the full list of supported models here.
