vLLM is a high-throughput, memory-efficient LLM inference engine with PagedAttention. The standard for self-hosted LLM serving with continuous batching and speculative decoding.
Reviewer scorecard
“The speed is mind-blowing. 500+ tokens/sec makes LLM responses feel instant. For latency-sensitive applications — autocomplete, real-time chat — nothing else comes close.”
“PagedAttention is a breakthrough for inference efficiency. The standard for production self-hosted LLM serving.”
“Speed is real but model selection is limited to open-source. No GPT or Claude. For apps that need the best model, you still need OpenAI/Anthropic. For speed-first use cases, Groq wins.”
“If you're self-hosting LLMs, vLLM is the obvious choice. Battle-tested and actively maintained.”
“Custom silicon for LLMs is the right long-term bet. GPUs are general-purpose. Groq is purpose-built. As open-source models match GPT quality, Groq becomes the default inference layer.”
“Self-hosted inference will remain important for latency, cost, and privacy. vLLM is the infrastructure layer.”
