zephyr-7b-beta is a kit in the Productivity category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-13. Download it on this page, a zip of its files. Nothing in it runs by itself.

Made by HuggingFaceH4

## About

### What it is

Zephyr-7B-beta is the second model in HuggingFaceH4's Zephyr series of chat assistants. It is a 7.2 billion parameter fine-tune of Mistral-7B-v0.1, trained on public synthetic datasets with direct preference optimization (DPO). The card says removing the built-in alignment from those datasets helped its scores and made it more helpful.

### Who it suits

It suits people who want a compact open chat model, from developers adding a self-hosted assistant to researchers studying how DPO shapes a model. The record lists English.

| Industry | Who uses it | How they use it | Example |
| --- | --- | --- | --- |
| Software | App developers | Add a small chat assistant they host themselves | A support bot with a custom persona |
| Research | Alignment researchers | Study a model tuned with DPO on public synthetic data | Compare it with its alpha predecessor |
| Hobby | Local model users | Chat with a 7B model on their own machine | Ask everyday questions in a chosen style |

People who need strong coding or maths help can skip it, since the card says it trails proprietary models on those tasks.

### Where to use it

- Python with the Hugging Face transformers library, on Windows, macOS or Linux
- A hosted demo chat that the model card points to
- Your own machine, since the weights are about 14.5 GB in BF16 or an estimated 3.6 GB at 4-bit

| Use case | Who | What they get back |
| --- | --- | --- |
| General chat | Hobbyists | Helpful answers in conversation |
| Persona bots | Developers | Replies in a style set by a system message |
| Preference tuning research | Researchers | A reference model trained with DPO on UltraFeedback |

### How to set it up

You need a few things first.

- Python and pip
- The transformers library and torch
- Memory or disk for the weights, about 14.5 GB in BF16

1. Install the Hugging Face hub tool with pip.
2. Download the model files to your computer.
3. Load the model in Python with the transformers pipeline, as the card shows.

```sh
pip install -U huggingface_hub
hf download HuggingFaceH4/zephyr-7b-beta
```

### How to use it

You build a pipeline for text generation, then pass a list of messages. A system message sets the persona and a user message holds the question. The card formats them with the tokenizer's chat template before generating.

```python
import torch
from transformers import pipeline

pipe = pipeline("text-generation", model="HuggingFaceH4/zephyr-7b-beta", torch_dtype=torch.bfloat16, device_map="auto")

messages = [
    {
        "role": "system",
        "content": "You are a friendly chatbot who always responds in the style of a pirate",
    },
    {"role": "user", "content": "How many helicopters can a human eat in one sitting?"},
]
```

| Tool | What it does |
| --- | --- |
| pipeline() | Loads the model for text generation in transformers |
| torch\_dtype=torch.bfloat16 | Loads the weights in BF16 |
| device\_map="auto" | Lets the library place the model on available devices |
| messages list | Holds the system persona and the user question |
| Chat template | Formats the messages the way the model expects |

### Example

You set the system message to a friendly chatbot that answers like a pirate, then ask how many helicopters a human can eat in one sitting. The model returns a text reply, which you should expect in that pirate style.

### For newcomers and experts

If you are new, a chat model is a program that answers typed questions. Download the files, run the pipeline example above, and change the system message to see how the reply style changes.

Underneath, the model was first fine-tuned on a filtered version of UltraChat, a set of synthetic dialogues made by ChatGPT. It was then aligned with the TRL DPOTrainer on UltraFeedback, which holds 64k prompts with completions ranked by GPT-4. The card reports an MT-Bench score of 7.34 and an AlpacaEval win rate of 90.60 percent.

Mistral-7B-v0.1 base model → Fine-tune on filtered UltraChat dialogues → DPO on UltraFeedback rankings → Chat through the tokenizer template

### Good to know

- License: MIT.
- Cost to run: no API key or paid service named. You supply the hardware, and the weights download from Hugging Face.
- Data it reaches: only the prompts you pass in. The card names no file, web or account access.
- Not for: complex coding and maths, where the card says it trails proprietary models. The card also warns it is likely to produce problematic text when asked to.
