+# **Llama 2**
+
+Llama 2 is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. This is the repository for the 7B fine-tuned model, in `npz` format suitable for use in Apple's MLX framework.
+
+Weights have been converted to `float16` from the original `bfloat16` type, because `numpy` is not compatible with `bfloat16` out of the box.
+
+How to use with [MLX](https://github.com/ml-explore/mlx).
+
+```bash
+# Install mlx, mlx-examples, huggingface-cli
+pip install mlx
+pip install huggingface_hub hf_transfer
+git clone https://github.com/ml-explore/mlx-examples.git
+
+# Download model
+export HF_HUB_ENABLE_HF_TRANSFER=1
+huggingface-cli download --local-dir Llama-2-7b-chat-mlx mlx-llama/Llama-2-7b-chat-mlx
+
+# Run example
+python mlx-examples/llama/llama.py --prompt "My name is " Llama-2-7b-chat-mlx/ Llama-2-7b-chat-mlx/tokenizer.model
+```
+
+Please, refer to the [original model card](https://huggingface.co/meta-llama/Llama-2-7b-chat) for details on Llama 2.
