 This is an INT4 quantized version of the `Llama-2-13b-chat-hf` model. The Python packages used in creating this model are as follows:
 ```
-onnx==1.16.0
-onnxruntime-directml==1.18.0
-onnxruntime-genai-directml==0.2.0
-torch==2.3.0+cu121
-transformers==4.40.1
+onnx==1.16.1
+onnxruntime-directml==1.20.0
+onnxruntime-genai-directml==0.4.0
+torch==2.5.1
+transformers==4.45.2
 ```
 This quantized model is created using the following command:
 ```
 python -m onnxruntime_genai.models.builder -m meta-llama/Llama-2-13b-chat-hf -e dml -p int4 --extra_options {"int4_block_size"=128} -o ./Llama-2-13b-chat-hf-onnx-int4
 ```
-`onnxruntime_genai.models.builder` quantizes the model using `MatMul4BitsQuantizer` from `matmul_4bits_quantizer.py` of `onnxruntime/quantization/` with the `"DEFAULT"` method.
