Low-Rank Adaptation

Also called LoRA.

Low-rank adaptation (LoRA) fine-tunes a language model by training small low-rank matrices added to its weight layers while freezing the original weights, drastically reducing the number of trainable parameters.

Description

LoRA is a common alternative when prompting alone cannot reach the required behavior, and adapters can be swapped per task on one base model.
