Introduction

As language models Continue to evolve and grow in capabilities, one of the latest innovations is the Zepha 7B Beta. This model, developed by the Hugging Face H4 team, is a fine-tuned version of the Mod Mistral and has about 7 billion parameters. It can answer user questions, generate sentences, and act as a helpful assistant. In this guide, we will explore what Zepha 7B Beta can do, how it performs compared to other models, its training method, pricing, and limitations. Let's dive in!

What is Zepha 7B Beta?

Zepha 7B Beta is a fine-tuned version of the Mod Mistral, developed by the Hugging Face H4 team. It is the Second model in the Zephyr series and acts as a helpful assistant. With its capacity to tap into a wide range of web data and technical sources, Zepha 7B Beta can understand and generate sentences like a human. It has shown impressive performance in multiple benchmark tests and is more accurate than other models like Llama 2 Chat 70B. However, as a beta version, it is still being improved and should be used for educational and research purposes.

Model Performance on Mt Bench

Zepha 7B Beta has been tested on Mt Bench, a benchmark for evaluating language models. In the tests, Zepha 7B Beta scored 7.34, while Llama 2 Chat 70B scored 6.86. Additionally, Zepha 7B Beta achieved a win rate of 90.6% on AlpacaEvil's benchmarks, while Llama 2 Chat 70B had a win rate of 92.7%. These results indicate that Zepha 7B Beta is a reliable and high-performing model.

How is the Model Trained?

The training process of Zepha 7B Beta is fascinating and incorporates some unique components. The model is pre-trained on the Mod Mistral 7B, which is adaptable to various use cases. To train Zepha 7B Beta, the developers used the Ultra Feedback data set, which consists of approximately 64,000 Prompts collected from various resources. The model's training also involves the Direct Preference Optimization (DPO) method, which optimizes the model directly on the preference data. This training approach has shown better results compared to traditional methods and helps overcome challenges in reinforcement learning.

Comparison with GPT 4
