The term "NF4" is central to this "long paper" which revolutionized how large language models (LLMs) are fine-tuned on consumer hardware.

In the context of computer science and machine learning, refers to 4-bit NormalFloat , a specialized quantization data type introduced in the seminal paper QLoRA: Efficient Finetuning of Quantized LLMs by Tim Dettmers et al. (2023). 📄 Core Concept: The QLoRA Paper
