Our Verdict
vLLM is the de facto engine for serving open-source LLMs in production, and PagedAttention is the reason: memory-efficient paging and continuous batching squeeze several times the throughput from the same GPU when traffic spikes. The OpenAI-compatible server means existing clients and SDKs just work. You will need a GPU and real ops skills to run it well, and it serves models — it doesn't train them. For anything beyond personal tinkering, this is where self-hosted inference should start.
