Parameter-Efficient Fine-Tuning: LoRA, QLoRA, 2026 Methods
TL;DR Parameter-efficient fine-tuning (PEFT) trains a small set of new or selected weights on a frozen model, and LoRA is the right default for most teams. Pick QLoRA when GPU memory is the limit, since its 4-bit base let researchers fine-tune a 65-billion-parameter model on one 48GB GPU. Test DoRA, AdaLoRA, rsLoRA or PiSSA only after a benchmark on your
