+# Llama-2-13b-chat ONNX models for DirectML
+This repository hosts the optimized versions of [meta-llama/Llama-2-13b-chat-hf](https://huggingface.co/meta-llama/Llama-2-13b-chat-hf) to accelerate inference with ONNX Runtime for DirectML.
+
+## Usage on Windows (Intel / AMD / Nvidia / Qualcomm)
+```powershell
+conda create -n onnx python=3.10
+conda activate onnx
+winget install -e --id GitHub.GitLFS
+pip install huggingface-hub[cli]
+huggingface-cli download EmbeddedLLM/llama-2-13b-chat-int4-onnx-directml --local-dir .\llama-2-13b-chat
+pip install numpy
+Invoke-WebRequest -Uri "https://raw.githubusercontent.com/microsoft/onnxruntime-genai/main/examples/python/phi3-qa.py" -OutFile "phi3-qa.py"

+## What is DirectML
+DirectML is a high-performance, hardware-accelerated DirectX 12 library for machine learning. DirectML provides GPU acceleration for common machine learning tasks across a broad range of supported hardware and drivers, including all DirectX 12-capable GPUs from vendors such as AMD, Intel, NVIDIA, and Qualcomm.
