vLLM

vLLM is an open-source library for fast and memory-efficient LLM inference and serving. It implements the PagedAttention algorithm to optimize GPU memory usage during text generation, allowing larger models to run on limited hardware. The system dramatically increases throughput while reducing latency for production LLM deployments.

Companies need vLLM expertise now because the cost of serving large language models at scale has become a major bottleneck for AI applications. With the shift from experimental models to production deployments, organizations require 2-5x better throughput to make LLM services economically viable. The recent surge in multi-modal and multi-tenant LLM applications makes efficient serving infrastructure critical for competitive AI products.
