vLLM
by Community
A high-throughput and memory-efficient inference and serving engine for LLMs
OSS
vLLM
Added 1 June 2026
Overview
vLLM is a Python framework for serving large language models with optimized throughput and memory efficiency. It uses techniques like paged attention and continuous batching to reduce latency and increase request throughput compared to standard inference servers. Designed for production deployments that need to handle multiple concurrent requests.

Use cases
- Running inference servers that handle high request volume with low latency
- Reducing GPU memory footprint when serving large models
- Batching and scheduling inference requests efficiently
Pros
- Significantly higher throughput than standard LLM serving approaches
- Lower memory consumption enables serving larger models on same hardware
- Active community with 81k+ GitHub stars and ongoing development
Cons
- Requires Python and GPU infrastructure, not suitable for CPU-only deployments
- Steeper learning curve than simple inference libraries for basic use cases
- Performance gains depend on workload characteristics and batch patterns
