Groq vs vLLM

TL;DR: Groq is a hosted inference service built on proprietary LPU hardware optimizing for raw speed and low latency, while vLLM is an open-source serving engine you deploy yourself that maximizes throughput efficiency through advanced memory management (PagedAttention) and supports virtually any hardware platform. Choose Groq for instant access to extremely fast inference without infrastructure management, or vLLM if you need self-hosted deployment, want fine-grained control over optimization techniques like quantization and distributed inference, or require flexibility across different hardware vendors beyond NVIDIA/LPU.
