vLLM

The high-throughput open-source inference server for LLMs — uses PagedAttention and continuous batching to serve open-weights models at production rates on a single GPU.

Definition

What vLLM means in practice

vLLM is the open-source LLM inference server that has become the de facto choice for sovereign deployments. Its core innovations — PagedAttention (memory management for the KV cache borrowed from operating-system virtual memory) and continuous batching (new requests can join a batch mid-flight rather than waiting for the batch to complete) — give 3-5× the throughput of a naive transformers.generate loop. In MindMap deployments vLLM serves Llama 3.3 70B (quantised) on 2× H100, or Llama 3.3 8B on a single A100, with median time-to-first-token under 400ms at 30-50 concurrent users.
