 You can specify attention or linear layers. With the CLI, you can specify layers with `--target_modules "q_proj" "v_proj" "k_proj" "o_proj"` or `--target_modules "all-linear"`.
 
+#### Recommended target modules per model architecture 
+As per [LoRA paper](https://arxiv.org/pdf/2106.09685), section 4.2 , by using the query and value projection matrices, we can achieve reasonable quality with efficient GPU utilization. Hence, while thinking about what LoRA adapters to specify, we recommend starting with query and value matrices. You could also refer to the defaults specified by PEFT library for popular model architectures in section [TRANSFORMERS_MODELS_TO_LORA_TARGET_MODULES_MAPPING](https://github.com/huggingface/peft/blob/7b1c08d2b5e13d3c99b7d6ee83eab90e1216d4ba/src/peft/utils/constants.py#L70) as a good starting point.
