# PEFT

The [`~integrations.PeftAdapterMixin`] provides functions from the [PEFT](https://huggingface.co/docs/peft/index) library for managing adapters with Transformers. This mixin supports all non-prompt-learning PEFT methods (LoRA, IA3, AdaLoRA, and others). Prefix tuning methods (prompt tuning, prompt learning) aren't supported because they can't be injected into a torch module.
