When raw performance matters, vLLM wins, but Ollama often wins on everything else.
My benchmarks showed vLLM delivering up to 3.2x the requests-per-second of Ollama on identical hardware, with noticeably lower latency at high concurrency.
If you're not looking for the ultimate performance on the latest GPU hardware, then Ollama is still hard to beat. It installs in minutes, runs on laptops, supports CPU fallback, and provides a curated model hub plus on-the-fly model switching. If your typical load is a handful of concurrent users, batch jobs that can wait an extra second, or local exploration during development, Ollama’s “good-enough” performance is exactly that, good enough.
Ollama is the reliable daily driver that gets almost everyone where they need to go; vLLM is the tuned engine you unleash when the freeway opens up and you really need to fly.
