**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](https://raysummit.anyscale.com/flow/anyscale/raysummit2024/landing/page/eventsite)

## About
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](https://arxiv.org/abs/2210.17323), [AWQ](https://arxiv.org/abs/2306.00978), [SqueezeLLM](https://arxiv.org/abs/2306.07629), 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](https://docs.vllm.ai/en/latest/models/supported_models.html).
