โŒ = not implemented

โœ… = implemented

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

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