**The Third vLLM Bay Area Meetup (April 2nd 6pm-8:30pm PT)**
We are thrilled to announce our third vLLM Meetup!
The vLLM team will share recent updates and roadmap.
We will also have vLLM collaborators from Roblox coming up to the stage to discuss their experience in deploying LLMs with vLLM.
Please register [here](https://robloxandvllmmeetup2024.splashthat.com/) and join us!

## 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 and AMD GPUs
