llama.cpp
llama.cpp is the lightweight C/C++ inference engine that runs open LLMs efficiently on CPUs and consumer GPUs, serving as the foundation beneath many local AI tools like Ollama and LM Studio. Its GGUF quantization formats let large models fit into modest hardware without dedicated accelerators.

Our Verdict
llama.cpp is the free, open-source engine that made local LLMs practical: a lightweight C/C++ codebase that runs open models on ordinary CPUs, Apple Silicon, and consumer GPUs — no Python required. Its GGUF quantization and OpenAI-compatible server mode are the substrate beneath tools like Ollama and LM Studio. The trade-offs are real: it's command-line first, so you assemble your own interface, and quantized models give up a little quality for size. For developers who want maximum control with minimal footprint, this is the reference implementation — start here before reaching for wrappers.
