Zephyr-7B-beta

Next-Gen Open Chat Model by Hugging Face

What is Zephyr-7B-beta?

Zephyr-7B-beta is the latest iteration of Hugging Face’s open-weight conversational LLM, fine-tuned on the Mistral-7B base model using Direct Preference Optimization (DPO). It improves upon Zephyr-7B-alpha by offering safer, more helpful, and more aligned outputs—with better performance across instruction-following and multi-turn chat tasks.

With full open access and a strong safety-alignment focus, Zephyr-7B-beta provides an ideal foundation for developers seeking ethical, transparent, and efficient AI agents.
