+# LoftQ Initialization
+
+| [Paper](https://arxiv.org/abs/2310.08659) | [Code](https://github.com/yxli2123/LoftQ) | [PEFT Example](https://github.com/huggingface/peft/tree/main/examples/loftq_finetuning) |
+
+LoftQ (LoRA-fine-tuning-aware Quantization) provides a quantized backbone Q and LoRA adapters A and B, given a full-precision pre-trained weight W.
+
+This model, `Meta-Llama-3-70B-4bit-64rank`, is obtained from [LLAMA-3-70B](https://huggingface.co/meta-llama/Meta-Llama-3-70B). 
+The backbone is under `LoftQ/Meta-Llama-3-70B-4bit-64rank` and LoRA adapters are under the `subfolder='loftq_init'`.
+
+## Model Info
+### Backbone
+- Size: ~ 36 GiB
+- Loaded format: bitsandbytes nf4
+- Size loaded on GPU: ~36 GiB
+
+### LoRA adapters
+- rank: 64
+- lora_alpha: 16
+- target_modules: ["down_proj", "up_proj", "q_proj", "k_proj", "v_proj", "o_proj", "gate_proj"]
+
+## Usage
+
+### Training
+Here's an example of loading this model and preparing for the LoRA fine-tuning.
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, BitsAndBytesConfig
+from peft import PeftModel
+
+MODEL_ID = "LoftQ/Meta-Llama-3-70B-4bit-64rank"
+
+base_model = AutoModelForCausalLM.from_pretrained(MODEL_ID)
+peft_model = PeftModel.from_pretrained(
+    base_model,
+    MODEL_ID,
+    subfolder="loftq_init",
+    is_trainable=True,
+)
+
+# Do training with peft_model ...
+```
