vLLM vs Ollama for Production LLM Serving in 2026: The Honest Comparison
Choosing between vLLM and Ollama for serving LLMs in production is not a matter of which tool is “better” — it is a matter of which tool solves the problem you actually have. vLLM serves 18.4 million Docker pulls and 2.79 million weekly PyPI downloads from teams running high-throughput inference APIs on GPU clusters.
