Model Card for SungJoo/llama2-7b-sft-detox

This model is an instruction-tuned version of meta-llama/Llama-2-7b-hf, fine-tuned to reduce toxicity in Large Language Models (LLMs).

Model Details

Model Description

This is an instruction-tuned model based on the LLaMA-2-7b architecture. It has been fine-tuned using a comprehensive instruction dataset specifically designed for detoxification of LLMs.

• Developed by: Sungjoo Byun (Grace Byun)
• Model type: Auto-regressive language model
• Language(s) (NLP): English
• License: Apache License 2.0
• Finetuned from: meta-llama/Llama-2-7b-hf

Model Sources

• Repository: TBD
• Paper: TBD

Uses

This model is intended to be used for generating less toxic language in various applications, including chatbots and other NLP systems.

Bias, Risks, and Limitations

While this model aims to reduce toxicity, it may still generate biased or harmful content. Users should apply this model with caution and review outputs for sensitive applications.

How to Get Started with the Model

Use the code below to get started with the model:

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("SungJoo/llama2-7b-sft-detox")
model = AutoModelForCausalLM.from_pretrained("SungJoo/llama2-7b-sft-detox")

Training Details

Training Data

The model was fine-tuned using a dataset specifically created to detoxify LLMs. This dataset will be publicly available soon.

Training Procedure

The model was trained using full fine-tuning with the following hyperparameters:

The training was conducted on 4 A100 80GB GPUs.

Objective

The main objective of this research is to reduce toxicity in LLMs by applying instruction tuning and Direct Preference Optimization (DPO). This version has been tuned with instruction tuning only. A comprehensive instruction and DPO dataset was constructed for this purpose, which will be released in the future.

The table above shows the effectiveness of this model in reducing bias, measured using the RealToxicityPrompt dataset and the Perspective API.
