Llama.cpp FAQ
What hardware do I need to run llama.cpp?
Llama.cpp runs on most modern hardware including Apple Silicon Macs (M1/M2/M3), NVIDIA GPUs (via CUDA), AMD GPUs (via HIP), and standard CPUs with AVX/AVX2 support. For optimal performance, a dedicated GPU or Apple Silicon with unified memory is recommended. Smaller quantized models can run on systems with as little as 8GB RAM.
Is llama.cpp free to use commercially?
Yes, llama.cpp is released under the MIT license, which permits commercial use, modification, and distribution without restrictions. However, the AI models you run through it may have their own licensing terms that you need to comply with.
How does llama.cpp compare to Ollama?
Llama.cpp is the underlying inference engine that powers many tools including Ollama. While llama.cpp provides maximum flexibility and performance tuning options, Ollama offers a more user-friendly experience with automatic model management. Choose llama.cpp for advanced customization, or Ollama for ease of use.
What models work with llama.cpp?
Llama.cpp supports 50+ model families including LLaMA, Mistral, Qwen, Gemma, Phi, Falcon, and many others. It also supports multimodal models like LLaVA for vision-language tasks. Models need to be in GGUF format, which most popular models provide or can be converted to.
Can I use llama.cpp as an API server?
Yes, llama.cpp includes llama-server, an OpenAI-compatible REST API server. This allows you to run a local LLM that works as a drop-in replacement for OpenAI API calls, making it easy to integrate with existing applications and tools.
