Description
HuggingFaceH4/zephyr-7b-beta is a 7 billion parameter language model, a fine-tuned version of mistralai/Mistral-7B-v0.1. It has been trained using Direct Preference Optimization (DPO) on a mixture of publicly available and synthetic datasets. This approach, which involves removing inherent dataset alignment, has led to improved performance on benchmarks like MT-Bench and AlpacaEval, positioning Zephyr-7B-β as a highly capable conversational AI.

The model is primarily designed for English language tasks and is released under the MIT license. Its architecture is GPT-like, and it has been fine-tuned on diverse synthetic dialogues generated by ChatGPT and further aligned using the 🤗 TRL library's DPOTrainer on the openbmb/UltraFeedback dataset. This dataset comprises 64,000 prompts and corresponding model completions ranked by GPT-4, contributing to the model's helpfulness.
Zephyr-7B-β demonstrates strong performance, ranking as the highest 7B chat model on MT-Bench and AlpacaEval at its release. It shows competitive results against larger open models like Llama2-Chat-70B on several MT-Bench categories. However, the model's performance on complex tasks such as coding and mathematics may lag behind proprietary models, indicating areas for future research and development.
While Zephyr-7B-β is adept at chat applications, it's important to note its limitations. It has not undergone the same safety alignment or in-the-loop filtering as models like ChatGPT, meaning it may generate problematic text if prompted to do so. Users should be aware of this potential for generating undesirable outputs. The model's base, mistralai/Mistral-7B-v0.1, likely trained on a mix of web data, books, and code, contributes to its broad capabilities.
Integration with Zephyr-7B-β can be achieved using the `pipeline()` function from the 🤗 Transformers library. The model supports chat templating for structured conversational input. The provided example demonstrates how to set up the model for text generation, including system and user messages, and how to format the prompt for optimal interaction.
