Libraries

How to use ek826/LlamaGuard-7b-4.65bpw-exl2 with Transformers:

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

pipe = pipeline("text-generation", model="ek826/LlamaGuard-7b-4.65bpw-exl2")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("ek826/LlamaGuard-7b-4.65bpw-exl2")
model = AutoModelForCausalLM.from_pretrained("ek826/LlamaGuard-7b-4.65bpw-exl2", device_map="auto")
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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Model Details

Original LlamaGuard 7b model can be found here

Llama-Guard is a 7B parameter Llama 2-based input-output safeguard model. It can be used for classifying content in both LLM inputs (prompt classification) and in LLM responses (response classification). It acts as an LLM: it generates text in its output that indicates whether a given prompt or response is safe/unsafe, and if unsafe based on a policy, it also lists the violating subcategories. Here is an example:

These are exl2 4.65bpw quantized weights. Original 7B model performs on binary classification of 2k toxic chat test examples Precision: 0.9, Recall: 0.277, F1 Score: 0.424

4.0bpw performs Precision: 0.92, Recall: 0.246, F1 Score: 0.389

4.65bpw performs Precision: 0.903, Recall: 0.256, F1 Score: 0.400
