The choice between GGUF and safetensors file formats for LLMs is determined by the runtime environment rather than performance metrics. GGUF, developed by the llama.cpp team, is a single-file container that includes quantization, tokenizer, and chat templates, and is supported by runtimes like Ollama and LM Studio. Safetensors, on the other hand, is a serialization format that stores models in their original precision and is favored for its security, preventing code execution during model loading, and is supported by libraries such as transformers and vLLM.
