GGUF
GGUF (GGML Unified Format) is the standard file format for ggml models, designed to replace the older GGML format. It supports metadata, tensor names, and various quantization types, enabling efficient inference across diverse hardware backends.
Key Characteristics
- Metadata Support: Stores model configuration, tokenizer info, and training details.
- Quantization: Native support for Q4_K_M, Q5_K_M, Q8_0, and other quantization schemes to reduce VRAM/RAM usage.
- Compatibility: Read by llama.cpp, Ollama, lm-studio, and other inference engines.
Ecosystem & Deployment
GGUF files are central to the local LLM ecosystem, allowing users to run large models on consumer hardware.
- llama.cpp: The primary reference implementation for GGUF inference.
- Ollama: Simplifies GGUF management via its library and CLI.
- LM Studio: Provides a GUI for loading and testing GGUF models.
