# Zephyr 7B β |
|
|
|
Zephyr is a series of language models that are trained to act as helpful assistants. Zephyr-7B-β is the second model in the series, and is a fine-tuned version of [mistralai/Mistral-7B-v0.1](https://huggingface.co./mistralai/Mistral-7B-v0.1) that was trained on on a mix of publicly available, synthetic datasets using [Direct Preference Optimization (DPO)](https://arxiv.org/abs/2305.18290). We found that removing the in-built alignment of these datasets boosted performance on [MT Bench](https://huggingface.co./spaces/lmsys/mt-bench) and made the model more helpful. However, this means that model is likely to generate problematic text when prompted to do so. You can find more details in the [technical report](https://arxiv.org/abs/2310.16944). |

This repository contains the `zephyr-7b-beta` weights in `npz` format suitable for use with Apple's MLX framework. |
|
|
|
## Use with MLX |
|
|
|
```bash |
|
pip install mlx |
|
pip install huggingface_hub hf_transfer |
|
git clone https://github.com/ml-explore/mlx-examples.git |
|
cd mlx-examples |
|
|
|
# Download model |
|
export HF_HUB_ENABLE_HF_TRANSFER=1 |
|
huggingface-cli download --local-dir-use-symlinks False --local-dir zephyr-7b-beta alvarobartt/zephyr-7b-beta |
|
|
|
# Run example |
|
python llms/mistral/mistral.py --model_path zephyr-7b-beta --prompt "My name is" |
|
``` |
|
|
