Overview

Zephyr is a series of language models from Hugging Face that are trained to be helpful assistants. The Zephyr-7B-β model is a fine-tuned version of Mistral-7B-v0.1. It was trained on a mix of publicly available, synthetic datasets using Direct Preference Optimization (DPO) to better align the model with user intent. Zephyr models are known for their strong performance on conversational and instruction-following benchmarks.
