llama.cpp vs vLLM

Short answer

llama.cpp: Lightweight C/C++ engine that runs quantized open models on CPU or GPU, with an OpenAI-compatible server. vLLM: High-throughput LLM inference server for GPUs with an OpenAI-compatible API. Both are in our Local model runtimes category.

Choose llama.cpp if you want: no GPU server needed.

llama.cpp publishes no official RAM figure, so we cannot compare hosting cost directly.

llama.cpp vs vLLM: FAQ

llama.cpp or vLLM: which should a small business choose?

Choose llama.cpp if you want: no GPU server needed. llama.cpp publishes no official RAM figure, so we cannot compare hosting cost directly.

Which is cheaper to self-host, llama.cpp or vLLM?

llama.cpp: not estimated (no official RAM figure). vLLM: GPU server (not estimated). Our estimate is the cheapest Hetzner Cloud plan that meets each project's official RAM and vCPU figure; it covers the server only.

How much hardware do llama.cpp and vLLM need?

llama.cpp: not published. vLLM: not published. vLLM needs a GPU for practical use.
