Instructions to use HuggingFaceH4/zephyr-7b-alpha with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use HuggingFaceH4/zephyr-7b-alpha with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="HuggingFaceH4/zephyr-7b-alpha")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("HuggingFaceH4/zephyr-7b-alpha")
model = AutoModelForCausalLM.from_pretrained("HuggingFaceH4/zephyr-7b-alpha")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Better or worse than Mistral?

Is it just me, or does Mistral7B instruct version provide a better user experience in chat? I tried generating Python code with Zephyr and it imported non-existent functions from sklearn. It never happened with Mistral in my experience.

Disagree, Zephyr is best next to oasst.

It is worse from my experience. It will make up answer eventhough I have alrd set prompt that it shouldnt do that. Mistral is much more reliable and behave like you you expect it to do

I tested physics, buddhism and philosophy topics, all worked out better than the original Mistral.

Writes w/o basic grammar. And it is pretty biased.
