What is llama.cpp?
A highly optimized, bare-metal C/C++ library designed to run AI model inference efficiently on consumer hardware, particularly MacBooks and standard CPUs.
llama.cpp strips away heavy machine learning frameworks like PyTorch to run inference with minimal overhead. It leverages Apple Silicon (Metal) and advanced quantization techniques (GGUF) to allow massive models to run smoothly on machines that lack enterprise-grade NVIDIA GPUs. It serves as the underlying engine for many user-friendly tools like Ollama.
How it relates to Orbit
llama.cpp’s server speaks the OpenAI-compatible API, so Orbit can route a complexity tier to it as a custom base URL. See Complexity Tiers & Routing for details.
When you would use it
You use llama.cpp directly when you need maximum performance, memory efficiency, and granular control over how a local model executes on restricted hardware.
Common operations
- Compiling a customized inference engine for edge devices.
- Running large Llama models on consumer Mac hardware.
