Model Card for Zephyr 7B β
Zephyr is a series of language models that are trained to act as helpful assistants. Zephyr-7B-β is the second model in the series, and is a fine-tuned version of mistralai/Mistral-7B-v0.1 that was trained on on a mix of publicly available, synthetic datasets using Direct Preference Optimization (DPO). We found that removing the in-built alignment of these datasets boosted performance on MT Bench and made the model more helpful. However, this means that model is likely to generate problematic text when prompted to do so. You can find more details in the technical report.
Model description
- Model type: A 7B parameter GPT-like model fine-tuned on a mix of publicly available, synthetic datasets.
- Language(s) (NLP): Primarily English
- License: MIT
- Finetuned from model: mistralai/Mistral-7B-v0.1
Model Sources
- Repository: https://github.com/huggingface/alignment-handbook
- Demo: https://huggingface.co/spaces/HuggingFaceH4/zephyr-chat
- Chatbot Arena: Evaluate Zephyr 7B against 10+ LLMs in the LMSYS arena: http://arena.lmsys.org
Performance
At the time of release, Zephyr-7B-β is the highest ranked 7B chat model on the MT-Bench and AlpacaEval benchmarks:
Model | Size | Alignment | MT-Bench (score) | AlpacaEval (win rate %) |
---|---|---|---|---|
StableLM-Tuned-α | 7B | dSFT | 2.75 | - |
MPT-Chat | 7B | dSFT | 5.42 | - |
Xwin-LMv0.1 | 7B | dPPO | 6.19 | 87.83 |
Mistral-Instructv0.1 | 7B | - | 6.84 | - |
Zephyr-7b-α | 7B | dDPO | 6.88 | - |
Zephyr-7b-β 🪁 | 7B | dDPO | 7.34 | 90.60 |
Falcon-Instruct | 40B | dSFT | 5.17 | 45.71 |
Guanaco | 65B | SFT | 6.41 | 71.80 |
Llama2-Chat | 70B | RLHF | 6.86 | 92.66 |
Vicuna v1.3 | 33B | dSFT | 7.12 | 88.99 |
WizardLM v1.0 | 70B | dSFT | 7.71 | - |
Xwin-LM v0.1 | 70B | dPPO | - | 95.57 |
GPT-3.5-turbo | - | RLHF | 7.94 | 89.37 |
Claude 2 | - | RLHF | 8.06 | 91.36 |
GPT-4 | - | RLHF | 8.99 | 95.28 |
In particular, on several categories of MT-Bench, Zephyr-7B-β has strong performance compared to larger open models like Llama2-Chat-70B:
However, on more complex tasks like coding and mathematics, Zephyr-7B-β lags behind proprietary models and more research is needed to close the gap.
Intended uses & limitations
The model was initially fine-tuned on a filtered and preprocessed of the UltraChat
dataset, which contains a diverse range of synthetic dialogues generated by ChatGPT.
We then further aligned the model with 🤗 TRL's DPOTrainer
on the openbmb/UltraFeedback dataset, which contains 64k prompts and model completions that are ranked by GPT-4. As a result, the model can be used for chat and you can check out our demo to test its capabilities.
You can find the datasets used for training Zephyr-7B-β here
Here's how you can run the model using the pipeline()
function from 🤗 Transformers:
# Install transformers from source - only needed for versions <= v4.34
# pip install git+https://github.com/huggingface/transformers.git
# pip install accelerate
import torch
from transformers import pipeline
pipe = pipeline("text-generation", model="HuggingFaceH4/zephyr-7b-beta", torch_dtype=torch.bfloat16, device_map="auto")
# We use the tokenizer's chat template to format each message - see https://huggingface.co/docs/transformers/main/en/chat_templating
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?"},
]
prompt = pipe.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
outputs = pipe(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
print(outputs[0]["generated_text"])
# <|system|>
# You are a friendly chatbot who always responds in the style of a pirate.</s>
# <|user|>
# How many helicopters can a human eat in one sitting?</s>
# <|assistant|>
# Ah, me hearty matey! But yer question be a puzzler! A human cannot eat a helicopter in one sitting, as helicopters are not edible. They be made of metal, plastic, and other materials, not food!
Bias, Risks, and Limitations
Zephyr-7B-β has not been aligned to human preferences for safety within the RLHF phase or deployed with in-the-loop filtering of responses like ChatGPT, so the model can produce problematic outputs (especially when prompted to do so).
It is also unknown what the size and composition of the corpus was used to train the base model (mistralai/Mistral-7B-v0.1
), however it is likely to have included a mix of Web data and technical sources like books and code. See the Falcon 180B model card for an example of this.
