Our recommendation

Reach for vLLM when a GPU server needs to serve many people at once — continuous batching and PagedAttention keep one card ahead of a whole team's chat traffic, behind the same OpenAI-compatible API your clients already speak. If it's just you, or your VPS has no GPU, Ollama does the job with a tenth of the setup.

What you need

Install

Run these commands on your server:

# vLLM — official image needs an NVIDIA GPU (CPU builds exist but are a separate image)
docker run -d --runtime nvidia --gpus all -v ~/.cache/huggingface:/root/.cache/huggingface \
  -p 8000:8000 --ipc=host vllm/vllm-openai:latest --model Qwen/Qwen3-0.6B

What you take on

vLLM is production-grade serving infrastructure, and it asks you to operate like it:

non-negotiableIt effectively requires an NVIDIA GPU. The official vllm/vllm-openai image assumes CUDA — you'll install the drivers and the NVIDIA container toolkit before anything serves, and the CPU builds exist mostly for development, not the throughput vLLM is chosen for.

non-negotiableVRAM math comes first. vLLM loads full Hugging Face weights, so the model claims most of your card before the clever cache management helps — size the GPU to the model you actually want to serve, or startup will fail with an out-of-memory error, not a warning.

non-negotiableIt moves fast. Releases land frequently and flags shift between them — pin an exact image tag rather than latest, and re-read the server flags on every upgrade instead of assuming yours still mean the same thing.
