* Training LoRAs with GPTQ models also works with the Transformers loader. Make sure to check "auto-devices" and "disable_exllama" before loading the model.

** Requires the monkey-patch. The instructions can be found here.

*** Multi-LoRA in PEFT is tricky and the current implementation does not work reliably in all cases.
