vLLM / Inference Serving Stack

Open-source inference engine standard

vLLM (with SGLang, TensorRT-LLM) became the de facto open serving engine that neoclouds and enterprises use to run open models efficiently via PagedAttention. It is strategically important because it commoditizes inference serving, pressuring proprietary API margins and enabling the neocloud business model.
