GGUF - Quantization Format for llama.cpp

The GGUF (GPT-Generated Unified Format) is the standard file format for llama.cpp, enabling efficient inference on CPUs, Apple Silicon, and GPUs with flexible quantization options.

When to use GGUF

Use GGUF when:

• Deploying on consumer hardware (laptops, desktops)
• Running on Apple Silicon (M1/M2/M3) with Metal acceleration
• Need CPU inference without GPU requirements
• Want flexible quantization (Q2_K to Q8_0)
• Using local AI tools (LM Studio, Ollama, text-generation-webui)

Key advantages:

• Universal hardware: CPU, Apple Silicon, NVIDIA, AMD support
• No Python runtime: Pure C/C++ inference
• Flexible quantization: 2-8 bit with various methods (K-quants)
• Ecosystem support: LM Studio, Ollama, koboldcpp, and more
• imatrix: Importance matrix for better low-bit quality
