Frequently Asked Questions 常见问题

What is llama.cpp? ▼

llama.cpp is a high-performance C++ implementation for running Large Language Models (LLMs) efficiently on consumer hardware. It supports quantized models (GGUF format) that can run on CPU, Apple Silicon, NVIDIA, and AMD GPUs.

What is GGUF format? ▼

GGUF (GPT-Generated Unified Format) is a binary file format for quantized LLM weights, introduced by llama.cpp. Quantization reduces model size by 4–8x, enabling large models to run on consumer hardware with acceptable accuracy loss.

How does llama.cpp compare to Ollama? ▼

llama.cpp is the underlying inference engine that Ollama uses internally. Ollama wraps llama.cpp with a user-friendly CLI and model management system. Use Ollama for easy model management; use llama.cpp directly when you need low-level control or maximum performance tuning.
