What is vLLM?
vLLM is a high-throughput and memory-efficient inference and serving engine for large language models (LLMs). Originally developed at UC Berkeley's Sky Computing Lab, it has grown into one of the most active open-source AI projects with over 2000 contributors. vLLM is designed for speed and flexibility, leveraging advanced techniques like PagedAttention to manage memory efficiently, enabling high throughput even with large models. It supports seamless integration with Hugging Face, offering compatibility with 200+ model architectures including LLaMA, Mistral, Falcon, and GPT-NeoX. vLLM provides a user-friendly Python API and supports popular serving frameworks like OpenAI-compatible API, making it easy to deploy models in production. Key features include continuous batching, tensor parallelism, and prefix caching, which optimize resource utilization and reduce latency. Use cases range from real-time chatbots and code generation to large-scale document processing and research. vLLM can be installed via pip or uv, and built from source for customization. Its documentation and community forums offer extensive support. By combining high performance with ease of use, vLLM empowers developers and researchers to deploy LLMs efficiently, reducing costs and improving user experience. Whether you are building a production-grade service or experimenting with cutting-edge models, vLLM provides the tools needed to scale inference workloads with minimal overhead.
