LLaMA2-13b-Stop-Hate

LLaMA2 Fine-Tuned on not Engaging with Hate Speech

This model was created as part of the work "Decoding Hate: Exploring Language Models' Reactions to Hate Speech," which was accepted for the main conference of NAACL 2025.

Model Description

This model is a fine-tuned version of meta-llama/Llama-2-13b-chat-hf on a hate speech dataset using the PEFT approach, to prevent the model from exacerbating hate discourse.

Intended Uses & Limitations

This model is intended for research purposes in conversational applications to stop hate speech generation.

Bias, Risks, and Limitations

• Biases: The model may carry biases present in the training data.
• False Positives/Negatives: It's not perfect and may continue some hate speech conversations.
• Domain Specificity: Performance may vary across different domains.

How to Get Started with the Model

Use the code below to get started with the model.

from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM, AutoTokenizer, Conversation, pipeline

# Load the model
config = PeftConfig.from_pretrained("irlab-udc/LLaMA2-13b-Stop-Hate")
base_model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-2-13b-chat-hf", config=config)
model = PeftModel.from_pretrained(base_model, "irlab-udc/LLaMA2-13b-Stop-Hate")
tokenizer = AutoTokenizer.from_pretrained("irlab-udc/LLaMA2-13b-Stop-Hate")

# Test the model
chatbot = pipeline(task="conversational", model=model, tokenizer=tokenizer)
conversation = Conversation("Your input text here")
conversation = chatbot(conversation)
result = conversation.messages[-1]["content"]
