Ollama, vLLM, and llama.cpp: Choosing the Right Local LLM Engine

This article compares three local LLM engines: Ollama, vLLM, and llama.cpp, focusing on their performance for different use cases. For single users on a laptop, Ollama and llama.cpp are recommended due to their ease of use and lower resource requirements. vLLM is highlighted as the superior choice for GPU servers handling many concurrent users, owing to its advanced features like PagedAttention and continuous batching for higher throughput. Benchmarks on an Apple M1 showed Ollama was faster for single requests by default, but llama.cpp handled concurrent requests more efficiently until Ollama was configured with parallel processing. AI
