**TLDR:** An approach that performs LoRA adaptation on a quantized base model to enable fine-tuning at lower hardware cost.

<p>QLoRA is a major practical innovation that makes it possible to adapt large language models with more limited GPU memory. The base model is kept at lower precision while LoRA layers are trained. This significantly reduces training cost while preserving task performance in many settings. It is especially valuable for individual developers and enterprise prototyping.</p>
